Product Description

Good Quality Weldolet

The branch pipe stand is also called branch pipe seat, saddle, saddle pipe joint. Reinforced pipe fittings mainly used for branch pipe connection, instead of branch pipe connection types such as reducing tee, reinforcing plate, and strengthening pipe section. It has outstanding advantages such as safety and reliability, cost reduction, simple construction, improvement of medium flow channels, standardization of series, and convenient design and selection, especially in high-pressure, high-temperature, large-diameter, thick-walled pipelines.

usual format

The main body of the branch pipe is made of high-quality forgings, and the materials used are the same as those of the pipeline, such as carbon steel, alloy steel, stainless steel, etc. The branch pipe base and the main pipe are welded, and the connection with the branch pipe or other pipes (such as short pipes, wire plugs, etc.), instruments, and valves has three types: butt welding connection, socket welding connection, and threaded connection. The commonly used manufacturing execution standards for branch pipe platforms include MSS SP-97, GB/T19326 and other standards.

Features

The branch pipe stand has outstanding advantages such as safety and reliability, lower cost, simple construction, improved medium flow path, serialization and standardization, and convenient design and selection, especially in high-pressure, high-temperature, large-diameter, thick-walled pipelines. connection method.

composition technology

1. The welded branch pipe stand is generally made of integral forgings. The structure of the branch pipe stand is divided into the main pipe connection end, the reinforcement part, and the branch pipe connection end.

2. Welding procedure evaluation of branch pipe stand The groove of the weld of the branch pipe stand is a unilateral V-shaped groove, and the form of the weld can be determined as a combination of butt weld (groove weld) and fillet weld.

3. Welder qualification requirements for pipe stand Welders need to obtain relevant welding qualifications in accordance with the relevant provisions of the "Special Equipment Welding Operators Examination Rules".

For project qualification, when considering the coverage of the outer diameter of the pipe, the groove surface diameter of the branch pipe stand (outer diameter of the branch pipe) should be considered, and the diameter of the main pipe is not considered in the welder qualification. When there is a transition slope, the groove surface diameter refers to the actual diameter measured from the groove surface, which is generally smaller than the outer diameter of the branch pipe stand, and the pipe stand is welded as a combined weld of butt weld and fillet weld with groove for branch pipe. Therefore, the welder can cover it with a 6G pipe certificate.

Classification

1. Butt welding branch pipe stand is a common branch connection. Its end is beveled and connected with straight pipe butt welding, so it is considered as a butt welded pipe fitting. The design of the butt-welded pipe stand minimizes stress concentrations and provides overall reinforcement. There are three pressure grades for butt welding branch pipe stand: STD, XS and Sch160.

2. The base of the socket and socket branch is the same as that of the butt welding branch, but its branch connection adopts socket welding connection. There are two pressure levels for the socket and branch pipe stand, 3000# and 6000#.

3. The base of the threaded branch pipe is the same as that of the butt welding branch, but the branch connection is threaded and does not require welding. There are two pressure levels of 3000# and 6000# for the threaded branch.

4. The mitered branch pipe stand is used for 45° branch. Butt welding, socket welding and threaded connections can be used for connection with branch pipes.

5. The elbow branch stand is used to provide branch connections on long radius elbows or short radius elbows. Butt welding, socket welding and threaded connections can be used for connection with branch pipes.

6. The short pipe branch is often used for valve installation and exhaust. Available in thicknesses XS and XXS, lengths from 3.1/2" to 6.1/2", with socket or male threaded ends.

7. The shape of the embedded socket is corrugated and the overall reinforcement is provided. It is butt-welded connection with the branch pipe, which is often used in low-pressure pipelines.
