Abstract
The utility model relates to a combined pipe piece formed by connecting a flange and a pipe piece, wherein the size of the flange is the same as a pipe piece joint. Different frocks can be made according to arranging size needs for the combined pipe piece. Thus, the pipe matching speed is high, and size is exact and uniform; the on-site arrangement is simple and easy, and the arranging speed is high; not only the quality can be ensured, but also the assembling time can be saved.
Description
Technical field
The utility model relates to the pipe fitting standard configurations, relates in particular to a kind of combined pipe fitting.
Background technique
In the middle of the use of pipe fitting, normally with standard pipe fitting (comprising elbow, threeway, four-way, reducer fitting etc.) and standard flange pipe arrangement, welding, heat treatment at the scene.Pipe fitting and flange are prepared at the scene, owing to do not have benchmark and frock, so accuracy of manufacturing (size and perpendicularity, parallelism) is low; Yielding, easy to crack with associated conduit welding back, cause medium to reveal easily; It is slow that preparation speed is installed, and the pipe fitting configuration is random big; Because be on-the-spot preparation, size can not be accomplished unified, so the pipe fitting assembly is not a dimensional standard, so can't exchange at all, brings great difficulty for the later stage retubing; Moreover, there is not good heat-treat condition, welding stress can't fully be eliminated, and the long-play weld seam is easy to generate crackle, has therefore reduced the bulk life time of equipment.
The model utility content
The purpose of this utility model provides a kind of, change the situ configuration of pipe fitting and flange into batch configuration in advance, make that each pipe fitting size is unified, the accuracy of form and position is high, interchangeability is strong, thereby reach the combined pipe fitting that the pipe fitting standardization is made, to solve above-mentioned defective of the prior art.
For achieving the above object, the utility model adopts following technological scheme.
A kind of combined pipe fitting that the utility model provides, this combined pipe fitting is connected and composed by flange and pipe fitting, and described flange and pipe fitting joint are measure-alike.
Wherein, described flange and described pipe fitting are connected by casting or screw thread or welding manner.
Wherein, described pipe fitting is an elbow.
Wherein, described pipe fitting is threeway.
Wherein, described pipe fitting is a four-way.
Wherein, described pipe fitting is a reducer.
Combined pipe fitting of the present utility model can require to make different frocks according to installation dimension, makes that pipe arrangement speed is fast, and size is accurate, unified; On-the-spot simple installation, easily row, installation rate are fast, both can ensure the quality of products, and can save installation time again.

Embodiment
The combined pipe fitting that the utility model proposes is described as follows in conjunction with the accompanying drawings and embodiments.
Combined pipe fitting of the present utility model, this combined pipe fitting is connected and composed by flange and pipe fitting, and flange and pipe fitting joint are measure-alike.Described flange and described pipe fitting are connected by casting or screw thread or welding manner.This pipe fitting can be standard or off-gauge elbow, threeway, four-way or reducer, and flange quantity can be decided according to the quantity different and assembling of pipe fitting.
It is prefabricated that combined pipe fitting of the present utility model can require to carry out batch according to installation dimension, guarantees the dimensional accuracy and the Geometrical Tolerance Principle of each combined pipe fitting, welds with the pipe fitting that links to each other at the scene then.
The utility model can be used for various large-scale double pipe heaters.Double pipe heater has many places, a plurality of elbow, pipe fitting that has flange, earlier with various flanges and elbow, pipe fitting according to the installation dimension requirement, be prefabricated into the combined pipe fitting of unified size of the present utility model in batches, weld with the pipe fitting that links to each other at the scene then, easy, the easy row of installation process, installation rate is fast, has promptly guaranteed quality, has saved the time again.And through long runtime verification, combined pipe fitting and other pipe fitting joint acomia change shape and leakage were not changed yet, and can guarantee the normal operation of producing.
Shown in Fig. 1-2, the combined pipe fitting of present embodiment is connected and composed with elbow 2 by two flanges 1 of same size.Flange 1 can be connected two of elbow 2 by casting or screw thread or welding manner.Elbow 2 can be standard or non-standard elbow.
As shown in Figure 3, the combined pipe fitting of present embodiment is connected and composed with threeway 3 by three flanges 1 of same size.Flange 1 can be connected three joints of threeway 3 by casting or screw thread or welding manner.Threeway 3 can be standard or non-standard threeway.
Embodiment 3
As shown in Figure 4, the combined pipe fitting of present embodiment is connected and composed with four-way 4 by four flanges 1 of same size.Flange 1 can be connected four joints of four-way 4 by casting or screw thread or welding manner.Four-way 4 can be standard or non-standard four-way.
As shown in Figure 5, the combined pipe fitting of present embodiment is connected and composed by two identical with 5 liang of joint dimensions of reducer respectively flanges 1.Flange 1 can be connected two joints of reducer 5 by casting or screw thread or welding manner.Reducer 5 can be standard or non-standard reducer.
Above mode of execution only is used to illustrate the utility model; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technological schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
