Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a piping production plan management apparatus used for planning and managing the production of piping used for piping work in an oil plant or the like.
[0002]
[Prior art]
Conventionally, when piping work is done by prefabrication work and site work, first make a piping diagram for the piping of the target plant, make a functional isometric diagram describing the welded joint from this piping diagram, and then add this functional isometric diagram A production isometric diagram is created based on the data necessary for actual welding, such as piping dimensions, welded joint types, piping materials, etc. Further, a piece diagram in which this production isometric diagram is divided into pieces based on the size that can be manufactured in the factory is created.
[0003]
In general, an engineering company that designs a plant creates a functional isometric diagram, and a piping company that actually performs piping work creates a production isometric diagram. Therefore, it takes a lot of time and money to create production isometric drawings. Therefore, recently, a technique for automatically creating a production isometric diagram to some extent from a functional isometric diagram using a computer has been put into practical use. And this technique has begun to be adopted in some cases when manufacturing pipe prefabs using friction welding. In addition, some computers have been put into practical use for piping production planning and production management.
[0004]
[Problems to be solved by the invention]
However, since the conventional development focused on automatically creating a production isometric diagram from a functional isometric diagram, a piece diagram was created from an automatic welding joint determination technology, pipe dimension automatic determination technology, and production isometric diagram. Although the technology was developed, no further development was done. Therefore, in the range of the prior art, automatic creation of production isometric diagrams and production planning and production management of piping have been treated as completely different things.
[0005]
However, it is extremely effective to unify production isometric drawings and production planning and production management of piping for measures to reduce skilled workers, and to reduce production costs and improve productivity. I understand.
[0006]
An object of the present invention is to provide a pipe production plan management apparatus capable of unifying from production isometric drawing creation to pipe production planning and production management.
[0007]
It is another object of the present invention to provide a piping production plan management apparatus capable of determining the number of designated non-destructive inspection points required at the same time as creating a production isometric diagram and displaying it on the production isometric diagram.
[0008]
[Means for Solving the Problems]
In the present invention, the production isometric diagram data determining means is the functional isometric diagram data, the type of the welded joint input from the input means, the actual joint such as the welded joint welded in the prefab work and the welded joint welded in the field work. Based on data necessary for production and data necessary for welding such as welding allowance stored in the welding database, data necessary for creating a production isometric diagram is determined. Then, determination data such as the type of welded joint and the piping material determined along with the production isometric drawing are stored in the determination data storage database. The production plan and production management means performs production planning and production management of piping including prefab work and field work based on data accumulated in the decision data accumulation database.
[0009]
The most important point in piping work is the welded joint. Various types of welded joints are used as welded joints. The type of welded joint, weld shape, and piping material to be used are determined by the piping specifications (service class), and nondestructive depending on the service class and type of welded joint. The contents of the inspection are also defined. Therefore, in the present invention, this weld joint is used as a standard for unification. Therefore, in the present invention, the production isometric diagram data determining means is configured to determine data necessary for creating the production isometric diagram while assigning identification numbers to all the welded joints. The decision data storage database stores decision data based on the identification number.
[0010]
In this way, it is possible to centrally realize production management such as production isometric drawing, production planning such as material delivery, etc., quality management of welded parts, prefab construction and progress management of on-site construction. It becomes possible.
[0011]
The ratio of non-destructive inspection, that is, the sampling ratio required in the course of piping work at an oil plant or the like, for example, is specified as 5% for a butt weld of a certain service class. If the required number of non-destructive inspection points can be determined when creating a production isometric drawing, the production plan is simplified. Therefore, the present invention further includes a nondestructive inspection standard database for accumulating nondestructive inspection standard data relating to a predetermined nondestructive inspection according to the type of welded joint. And based on the nondestructive inspection standard data stored in the nondestructive inspection standard database, a function for determining the number of designated nondestructive inspection points required for each nondestructive inspection determined in advance according to the type of the welded joint, In addition, a function for notifying at least the types of weld joints, the number of each type, and the number of nondestructive inspection locations on the production isometric diagram is added to the production isometric diagram data determining means. In this way, the number of necessary non-destructive inspection points is displayed on the production isometric diagram, so that production management and quality management are facilitated.
[0012]
Also, if it is necessary to assign an identification number to parts other than welded joints to make production management easier (for example, when it is easier to search in pieces when viewing progress, etc.) A virtual welded joint may be set for the portion (for example, the entire piece including no welded joint). And an identification number is provided with respect to this virtual welded joint. If it does in this way, when the concept of attaching | subjecting an identification number to a welded joint is used, production management of the piping of the part which does not include a welded joint can also be performed easily.
[0013]

A change data input means for inputting is configured.
[0017]
FIG. 2 shows an example of a production isometric diagram output from the printer 6 based on the data determined by the production isometric data determination means 2. In the production isometric view, an isometric view is described in the area indicated by A, information on the piping material used in the area indicated by B is described, and information on the nondestructive inspection location of the nondestructive inspection of the welded joint is indicated in the area indicated by C. Is described. FIG. 3 is an enlarged view of the isometric view shown in the area A of FIG. 2, and FIG. 4 is an enlarged view of description of information regarding the nondestructive inspection location of the nondestructive inspection shown in the area C of FIG. 2. .
[0018]
The production isometric diagram data determination means 2 assigns identification numbers to all the welded joints when creating the production isometric diagram. The identification number assigned by the production isometric diagram data determination means 2 is composed of a combination of a line number, a piece number of each piece, and a weld joint number. Here, the piece is each part of the line divided on the basis of the length that can be prefabricated and transported in advance at the factory, and a piece diagram is created for each piece. The line number is given in three digits in order from the end of the pipe, for example “001”. The piece number is actually given in combination with the line number as “001-1201”. In this piece number, “001” is a line number, and “1201” is a piece number of a piece having the line. On the production isometric view, as shown in FIG. 3, the numbers “01” and “02” at the end of the piece number are indicated by a notation surrounded by a double ellipse. The weld joint numbers are, for example, “W01”, “W02” for welded joints for factory prefab welding, and “F09”, “F11” for welded joints for on-site welding, It is given in combination (see the section “Fitting number” in FIG. 6). In the production isometric view shown in FIG. 3, the weld joint number such as “W1” is displayed for the weld joint to be welded in the prefab work, and “FW9” is displayed for the weld joint to be welded in the field work. The weld joint number is displayed as "", and the weld joint number is displayed as "H24" in the weld joint of the welded portion of the support that supports the pipe. Of course, the display of the welded joint number on the drawing and the welded joint number used for giving the identification number may be different. As will be described in detail later, in the embodiment of the present invention, the weld joint number displayed on the drawing is different from the weld joint number used to give the identification number.
[0019]
When the identification number is determined as described above, the identification number assigned to each welded joint by the production isometric diagram data determination means 2 is, for example, “001-1201F13”. Although not a welded joint, a virtual welded joint may be set for a part (for example, the whole piece) necessary for production planning and production management, and an identification number may be assigned to that part. If you try to manage everything with welded joints, you can't manage pieces without welded joints, but if you set up virtual welded joints like this example, you can manage pieces without creating a database of pieces, for example. It also becomes possible to manage how many pieces have been installed on site.
[0020]
In piping construction, welded joints are the most important part, and if a database is created with identification numbers assigned to all welded joints as in the present invention, management of necessary materials, non-destructive inspection of welded joints, Production design and production management such as construction progress can be done easily and efficiently.
[0021]
Returning to FIG. 1, the decision data storage database 7 is determined in accordance with the creation of the production isometric diagram (data input from the input means 1 or data stored in the welding database 3 and the nondestructive inspection reference database 4. The determination data such as weld joint type, piping material, nondestructive inspection type, nondestructive inspection timing, nondestructive inspection location, heat treatment presence / absence, work execution date, work completion date, etc. Accumulated based on the identification number. In this example, the decision data storage database 7 includes a piping material database 7A and a welded joint database 7B. Although not shown, a LINE test database for storing data related to a test when the LINE is completed is also shown. included. In the piping material database 7A, determination data on piping materials necessary for construction work is accumulated based on the production isometric view. The data accumulated in the piping material database 7A are the material management means 8A in the production plan and production management means 8 for prefab construction and the material management in the production plan and production management means 8 'for site construction. It is used in the means 8'A, and is used for material procurement, material delivery, and material delivery management.
[0022]
In addition, the welded joint database 7B includes the service class, the type of welded joint to be used, the content of the welded joint, the type of nondestructive inspection, the nondestructive inspection time, the designation of the nondestructive inspection location, the presence of heat treatment, the work execution date, Determination data such as the completion date is stored or recorded with reference to the identification number of the weld joint. The contents to be recorded in the welded joint database 7B are arbitrary. In this example, the above contents are used in order to specify the nondestructive inspection location for the nondestructive inspection simultaneously with the production of the production isometric diagram. 7B. The contents of the data stored in the welded joint database 7B include information on the non-destructive inspection of the welded joint (see region C in FIG. 2) on the production isometric diagram, and the production plan and production management means for the prefab work. 8 is used for quality control of the welded portion in the quality control means 8B in 8 and the production plan for field work and quality control means 8'B in the production management means 8 '.

FIG. 4 shows an enlarged view of a region C in FIG. In order to facilitate understanding of the contents of data stored in the welded joint database 7B, the contents of FIG. 4 will be described first. First, the column “SERVICE CLASS” in the table of FIG. 4 indicates the service class (pipe specification) included in the line. Here, the service class is a class determined according to the temperature, pressure, type, and the like of the fluid flowing through the pipe, and various pipe elements (pipe, joint, etc.) are also determined thereby. In general, piping elements of the same service class are formed of the same material, and when the service class is different, the material of the piping element is often different. The column “NDI” indicates the contents of the nondestructive inspection. The notation in the uppermost line in the “NDI” column is the notation of the number of welded joints to be subjected to nondestructive inspection and the sampling rate (%) for nondestructive inspection. “WELDING” means a welded joint (welded joint) connected by ordinary welding, and “FRIC” means a pressure welded joint (welded joint) connected using friction welding. ing. “RT” means non-destructive inspection using X-rays, “MT” means non-destructive inspection using magnetism, and PT applies chemicals to welded joints to remove surface defects from color changes. A nondestructive inspection means a nondestructive inspection, and “UT” means a nondestructive inspection using ultrasonic waves. “BW” means that the type of welded joint is a butt weld, “SW” means that the type of welded joint is a socket weld, and “OTHERS” means that the type of welded joint is a boss or “SO” means that the type of welded joint is a slip-on flange weld, and “FILETT” means that the type of welded joint is a socket type fillet. It means a welded part, and “SUPPORT” means a joint welded part between the main pipe and the support that supports the main pipe. “FIRST LAYER” means the first layer of welding, and “COVER LAYER” means the final layer of welding. The numbers 1 to 14 displayed on the right side of “BW”... “SUPPORT” mean the combination number of the type of welded joint and the type of nondestructive inspection for each service class. For these 14 types of combinations, the sampling rate of the sample for nondestructive inspection is determined based on the designation in advance for each service class. The number under “Number” (eg, 14) is a specific non-destructive inspection (eg, X-ray non-destructive inspection) among welded joints in a particular service class line manufactured based on this fabrication isometric drawing. The number (for example, 5) under “%” indicates the sampling rate for nondestructive inspection. The number under “PTS” indicates the number of nondestructive inspection points to be designated. The operator who creates the production isometric diagram inputs the designation as the non-destructive inspection location of the appropriate welded joint from the input means 1 according to the number of non-destructive inspection locations to be designated. 2 in the welded joint database 7B.
[0024]
The contents and sampling rate of these nondestructive inspections are recorded in advance in the nondestructive inspection standard database 4. The production isometric diagram data determination means 2 reads out and determines the contents of nondestructive inspection for each welded joint (welded joint) from the nondestructive inspection standard database 4 at the stage of creating the production isometric diagram, and identifies the determination data. Record in the welded joint database 7B based on the number. In addition, the progress of construction and the result of nondestructive inspection are sequentially input from the input means 1 to the welded joint database 7B.

In step ST3, the specifications (service class, type of welded joint, type of nondestructive inspection, etc.) of all the welded joints (welded joints) are automatically set based on the data accumulated in the welding database and the nondestructive inspection standard database. To decide. In step ST4, a welding joint to be subjected to on-site welding in the on-site construction of piping is designated without performing welding when performing pipe prefab work at the factory from the input means 1. Regarding the designation of on-site welded joints, the degree of freedom in design is increased by enabling manual input designation. In step ST5, identification numbers are assigned to all the welded joints. At this time, a virtual weld joint is set and an identification number is assigned to the virtual weld joint. The identification number can be assigned according to the contents of the weld joint determined or specified previously.
[0028]
Next, in step ST6, the pipe dimensions are determined based on the welding allowance data stored in the welding database. The decision data is input to the piping material database in step ST9. In step ST7, the number of nondestructive inspection points is determined for each combination of service class, weld joint type, and nondestructive inspection type. In step ST9, the operator inputs a designation for setting the number of welded joints corresponding to the number of nondestructive inspection locations determined in step ST7 as nondestructive inspection locations. These determination data are input to the welded joint database 7B. In step ST9, the determined data is input to each database. In the production isometric diagram database, data necessary for drawing is input for each production isometric diagram. Of the above-mentioned specific data and decision data, those that can be displayed on the production isometric diagram are sequentially displayed in an appropriate display mode, so the operator can check the creation process of the production isometric diagram while viewing the CAD display screen. Manual input is also possible.
[0029]
