Abstract

The utility model relates to a socket welding 45-degree branch pipe seat which is used for carrying out socket welding connection of a pipeline branch from tapping in a main pipeline in an industrial metal pipeline. The socket welding 45-degree branch pipe seat comprises the main pipeline (1), a branch pipe (4) and a 45-degree branch pipe seat (3), wherein an inner hole at the root part of the 45-degree branch pipe seat (3) is a conical hole, an opening is arranged in the outer circular surface of the main pipeline (1), and the inner hole at the root part of the 45-degree branch pipe seat and the opening of the main pipeline (1) are aligned, welded and connected with each other; and the branch pipe end part of the 45-degree branch pipe seat (3) is in socket welding connection with the branch pipe (4). The socket welding 45-degree branch pipe seat does not need to carry out field processing and fabrication, does not need to additionally fabricate or purchase a stiffening ring and a double-socket pipe coupling, and is beneficial to safe running of the pipeline.

Description

45 ° of branch holders of SOCKET WELDING

(1) technical field

The utility model relates to 45 ° of branch holders of a kind of SOCKET WELDING.Be used for the SOCKET WELDING connection that the Industrial Metal pipeline carries out carrying out from the main pipe perforate pipe branch.Metal conduit link technical field.

(2) background technique

In the Industrial Metal pipeline, in order to improve pipeline quality, the following pipeline connection of DN50 adopts socket welded mode to carry out usually.In the time need connecting from the SOCKET WELDING that pipe branch is carried out in the main pipe perforate, its linkage structure is as shown in Figure 1: when the SOCKET WELDING of carrying out pipe branch from main pipe 1 perforate connected, at first an end of the short arm 7 that will be connected with main pipe 1 was made into the shape that matches with main pipe 1 excircle configuration and at this end making bevel for welding; This end that to lack arm 7 again leans against on main pipe 1 periphery finds branch location accurately, marks the line of perforations of main pipe 1 by hole shape in its root; Then along line to main pipe 1 perforate, be weldingly connected after the internal diameter of short arm 7 these ends and main pipe 1 perforate aligned; Intensity reduces after the pipeline tapping, need carry out reinforcement for openings, usually adopt the mode of stiffening ring 5 to carry out reinforcement, therefore to make the stiffening ring 5 that a surface conforms to main pipe 1 outer round surface shape with steel plate, it is inserted in short arm 7 is placed on the main pipe 1, endoporus and outer rim along stiffening ring 5 adopt the mode of built-up welding to be welded on the main pipe 1, and stiffening ring 5 melts the effect that metal plays reinforcement for openings jointly with applying of bead-on-plate weld 6; One end of the other end of short arm 7 and arm 4 is inserted respectively carry out SOCKET WELDING in the socket joint hole of double-bellmouth pipe collar 8 and be connected.Its shortcoming is:

1) need the end of the short arm of on-the-spot processing and fabricating, it is conformed to the main pipe outer round surface and process bevel for welding, difficulty is bigger;

2) need to make in addition or buying stiffening ring and double-bellmouth pipe collar; Need lack the welding of arm and stiffening ring respectively, the engineering time is long;

3) sudden change from the main pipe internal diameter to a short bore can cause the rapid change of pressure medium, is unfavorable for the safe operation of pipeline.

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of 45 ° of branch holders of SOCKET WELDING that do not need the short arm of on-the-spot processing and fabricating, do not need making in addition or purchase stiffening ring and double-bellmouth pipe collar and be beneficial to the safe operation of pipeline are provided.

The purpose of this utility model is achieved in that 45 ° of branch holders of a kind of SOCKET WELDING, comprise main pipe, arm and 45 ° of branch holders, the root endoporus of described 45 ° of branch holders is a taper hole, perforate on the main pipe periphery, the root endoporus of described 45 ° of branch holders and described main pipe perforate align and are weldingly connected; A tube end of 45 ° of branch holders is connected with the arm SOCKET WELDING.

Principle:

When the SOCKET WELDING of using 45 ° of branch holders to carry out pipe branch from the main pipe perforate connects, at first 45 ° of branch holders are leaned against on the cylindrical of main pipe and find branch location accurately, mark the line of perforations of main pipe by hole shape in the root of 45 ° of branch holders; Then along line to the main pipe perforate, be weldingly connected after the root endoporus of 45 ° of branch holders and main pipe perforate aligned; Carrying out SOCKET WELDING in the socket joint hole, end with 45 ° of branch holders of arm insertion again connects.The deposited molten metal of 45 ° of branch holders itself the reinforcement shape that has and the weld seams that are connected with main pipe plays the effect of reinforcement for openings jointly.

In the Industrial Metal pipeline, in the time need connecting from the SOCKET WELDING that pipe branch is carried out in the main pipe perforate, the utility model is by being weldingly connected 45 ° of branch holders of SOCKET WELDING and main pipe and branch pipe(tube) respectively, realizes connecting and the reinforcement for openings of pipeline from the branch of main pipe perforate; The cone structure of the inner gradual change of 45 ° of branch holders of SOCKET WELDING has improved the situation that pressure medium changes, and helps the safe operation of pipeline.

The beneficial effects of the utility model are:

1) bevel for welding of 45 ° of branch holders is made by factory and is finished, and has saved the time of the bevel for welding that the job site processing and fabricating conforms to the main pipe outer round surface;

2) 45 ° of branch holders itself the reinforcement shape that has and the weld seams that are connected with main pipe apply the effect that molten metal plays reinforcement for openings jointly, do not need to use the other reinforcement of stiffening ring;

3) cone structure of 45 ° of inner gradual changes of branch holder has improved the situation that pressure medium changes, and helps the safe operation of pipeline.
