Description
Technical Field
The application relates to the field of pipe processing, in particular to an adjustable connection method for ports of large-caliber stainless steel pipes.
Background
In recent years, field construction welding has been increasingly limited with the strengthening of national safety and environmental regulations. Because welding can lead to site fire hidden danger, a large amount of waste gas and waste residue can also be produced, serious pollution is caused to the environment, and the prohibition of site construction welding has become a common management measure.
In addition, in the diameter-reducing and diameter-expanding process of the stainless steel pipe with the large diameter of more than 300mm, huge force is required to be applied to overcome the strength of the material so as to enable the material to be plastically deformed. Typically, these tasks are performed using specialized large-scale equipment, and the construction site for installing the pipeline is hardly provided with such equipment, and even if the construction cost is not acceptable, the time and cost for on-site construction of the large-caliber stainless steel pipe are very high in the conventional pipeline engineering, and safety, environmental protection and quality problems are easy to occur.
If the method of the patent is adopted for connecting the large-caliber stainless steel pipe with the diameter of more than 300mm by adopting the CN 112628488B-a tensile strength enhancement connecting method for metal pipe fittings, when the metal connecting outer pipe and the reinforced inner pipe are subjected to step position limiting locking necking and necking, as mentioned above, the problems of difficult site necking construction difficulty (excessive force required for necking caused by large pipe wall thickness and large necking caused by large pipe diameter difference of the outer pipe and the inner pipe) and excessive deformation of the outer pipe caused by large necking are caused, and the problems of influencing the strength of the pipe body are caused, and the limitations and limitations seriously influence the progress and the efficiency of engineering projects.
Therefore, there is a need for a new pipe connection method that can achieve efficient, environmentally friendly and high quality pipe handling without being limited by field devices, thereby improving the progress and efficiency of engineering projects. This patent was designed to address this need.

For a clear and complete description of the technical solutions, the following examples are chosen for illustration; the following examples are some of the examples of the present application; other embodiments, which are obtained based on the present application without making any inventive effort, are within the scope of the present application.
In the following embodiments, it should be noted that, the terms "upper", "lower", "left", "right", "inner", "outer", "top/bottom", and the like are all based on the orientation or positional relationship shown in the drawings, and are merely for the sake of clarity in describing the present embodiment, and do not indicate or imply that the apparatus or element to be referred to must have a specific orientation, and therefore, should not be construed as limiting the application. Meanwhile, the "first" and "second" in the embodiments are used for distinguishing descriptive purposes only and are not represented as indicating or implying relative importance.
As shown in fig. 1-4, a first embodiment of the present application is an adjustable connection method for a large-caliber pipe port.
The large-caliber pipe is mainly used for conveying liquid, the pipe diameter (namely the outer diameter of the pipe) is usually selected according to the national standard during design, but the wall thickness of the pipe is selected according to the actual transfusion (mainly water conveying) pressure requirement, the actual use environment and the like, for example, a common rain and sewage drain pipe is generally a thin-wall drain pipe, a high-pressure water supply pipe is a thick-wall pipe, and as the pipe walls of the pipe are different in thickness, cavities with different sizes are required to be formed during the pipe adopting a snap connection method, therefore, the application adopts an annular snap cavity to carry out press connection on the 2 ports of the large-caliber pipe, and the design of a connecting piece needs to consider the factors such as the diameter, the length and the thickness of the pipe so as to ensure that the pipe achieves proper strength and rigidity; the welding construction is not allowed in the general field, so the connecting method is suitable for being processed in advance in factories to facilitate the field construction; based on the above, in order to match large-caliber pipes with different thicknesses, the outer pipe can be matched and connected only by selecting the inner connecting pipes with different outer diameters so as to realize adjustable connection. The method of the application comprises the following implementation steps:
step one, selecting a section of metal connecting outer tube 1 according to the outer diameter of a port of a large-caliber pipe 2, wherein the inner diameter of the connecting outer tube 1 is matched with the outer diameter of the port of the large-caliber pipe 2;
selecting a section of metal connecting inner pipe 3 according to the inner diameter of the port of the large-caliber pipe 2, wherein the outer diameter of the connecting inner pipe 3 is matched with the inner diameter of the port of the large-caliber pipe 2; expanding one end of the connecting inner tube 3 to match the expanded outer diameter of the end with the inner diameter of the connecting outer tube 1;
and step three, manufacturing a section of metal ring 4, wherein the thickness of the annular wall of the metal ring 4 is smaller than or equal to the difference between the inner diameter of the connecting outer tube 1 and the outer diameter of the connecting inner tube 3, so that the metal ring 4 can be sleeved between the connecting outer tube 1 and the connecting inner tube 3, and the connecting piece is ensured to have good sealing performance.
Step four, placing the metal ring 4 into the connecting outer tube 1, welding the metal ring 4 on the inner wall of the connecting outer tube 1 for fixing, and then plugging the connecting inner tube 3 into the connecting outer tube 1 to pass through the metal ring 4 until the expanded end of the connecting inner tube 3 is propped against the metal ring 4, so as to form a butt joint end component with an annular occlusion cavity;
if the method of directly welding the connecting inner pipe and the connecting outer pipe is adopted, the formed connecting annular cavity is fixed and can not be changed, the connecting annular cavity can only be used for connecting the pipes with one thickness, flexible allocation can not be realized, and if the pipes are processed in batches for storage, the connecting annular cavity can not be used and scrapped under the condition of adjusting the wall thickness of the pipes. The metal ring is welded on the inner wall of the connecting outer pipe for fixation, and then the connecting inner pipe is plugged into and matched with the connecting outer pipe to form the butt joint end component with the annular occlusion cavity, so that the connecting inner pipe with various specifications is convenient to operate, the matched connecting inner pipe is found according to the pipes with different wall thicknesses during connection, the annular cavities with different sizes are formed, the adjustable connection is realized, and the effects of reducing the cost and the storage are achieved.
Specifically, the length of the expanded end of the connecting inner tube 3 is smaller than the distance between the port of the connecting outer tube 1 and the weld metal ring 4, and the following two ways can be adopted for locking: the first way is that after the expanded diameter end of the connecting inner tube 3 is propped against the metal ring 4, the opening end of the connecting outer tube 1 corresponding to the connecting inner tube 3 is pressed and reduced, so that the expanded diameter end of the connecting inner tube 3 is limited between the metal ring 4 and the reduced diameter position of the connecting outer tube 1; the clamping or ring pressing tool can be used for locking the position of the connecting outer tube 1 corresponding to the port of the connecting inner tube 3 when the pressing is reduced, the connecting outer tube is pressed according to the specified pressure, and the selected pressure for the pipes with different pipe diameters belongs to common knowledge in the field. The connecting mode has the advantages of easy installation, convenient on site and strong adaptability, and can be suitable for pipelines with various sizes and shapes and be used for connecting different types of pipeline materials. In the second mode, after the expanded diameter end of the connecting inner tube 3 is propped against the metal ring 4, the opening end of the connecting inner tube 3 is welded with the inner wall of the connecting outer tube 1, so that the connecting inner tube 3 is fixed in the connecting outer tube 1. The inner pipe 3 is connected in a welding mode and is combined with the outer pipe 1 more tightly, so that higher connection strength can be provided, leakage is not easy to occur due to high temperature resistance, and the stability is stronger.
Fifthly, the end part of the other side of the connecting outer tube 1, which is opposite to the annular occlusion cavity, is welded to other connecting structural members to form a connector for site construction;
the other connecting members are other butt joint end members, and the connecting outer tubes 1 of the two butt joint end members are welded to form a straight connecting joint for being communicated with the straight pipe; the other connecting components can also be any one of elbow pieces, tee pieces and four-way pieces, and are used for being communicated with the pipe fittings in different directions.

selecting a section of metal connecting inner pipe 3 according to the inner diameter of the port of the large-caliber pipe 2, wherein the outer diameter of the connecting inner pipe 3 is matched with the inner diameter of the port of the large-caliber pipe 2; the middle part of the connecting inner pipe 3 is expanded to ensure that the expanded outer diameter of the end part is matched with the inner diameter of the connecting outer pipe 1, so that the replaceability of the inner pipe 3 is ensured, and the pipe diameter of the inner pipe 3 can be adjusted on site according to the wall thickness of the large-caliber pipe 2 to ensure that the meshing annular space gap formed by the inner pipe and the outer pipe 1 is matched with the wall thickness of the large-caliber pipe 2;
step three, manufacturing two sections of metal rings 4, wherein the thickness of the ring wall of the metal rings 4 is smaller than or equal to the difference between the inner diameter of the connecting outer tube 1 and the outer diameter of the connecting inner tube 3;
step four, respectively placing two sections of metal rings 4 into the two sections of connecting outer pipes 1, welding the metal rings 4 on the inner walls of the corresponding connecting outer pipes 1 to fix the two sections of connecting outer pipes 1, sleeving the two connecting outer pipes 1 from the two ends of the connecting inner pipes 3 until the metal rings 4 are propped against the diameter expanding end parts of the connecting inner pipes 3, and respectively forming two butt joint ports which are symmetrical left and right and provided with annular occlusion cavities at the two ends of the connecting inner pipes 3; simultaneously welding and connecting two adjacent ports of the outer connecting pipes;
