Product introduction
Branch pipe platform is also called branch pipe seat, saddle and saddle pipe joint. Reinforcing pipe fittings mainly used for branch pipe connection, instead of using reducing tee, reinforcing plate, reinforcing pipe section and other branch pipe connection types. It has many outstanding advantages, such as safety and reliability, cost reduction, simple construction, improved medium flow path, series standardization, convenient design and selection, etc. It is increasingly widely used in high-pressure, high-temperature, large-diameter, thick-wall pipes, replacing the traditional branch pipe connection method.
Common specifications
The main body of the branch pipe is made of high-quality forgings, which are made of the same material as the pipe, including carbon steel, alloy steel, stainless steel, etc. The branch pipe base and the main pipe are welded. There are three types of connection with the branch pipe or other pipes (such as short pipe, plug, etc.), instruments and valves: butt welding connection, socket welding connection and threaded connection. The commonly used manufacturing executive standards for branch manifolds include MSS SP-97, GB/T19326 and other standards.

classification
1. Butt-welding olets are the most common branch connectors. Its end is made into a groove and connected with the straight pipe by butt welding, so it is considered as a butt welding pipe. The design of butt-welded branch pipe platform minimizes stress concentration and provides overall reinforcement. Butt-welding branch pipe supports have three pressure classes: STD, XS and Sch160.
2. The base of socket-branch is the same as that of butt-welding branch, but its branch connection is connected by socket-welding. There are 3000 # and 6000 # pressure classes for socket-outlet.
3. The base of the threaded branch pipe platform is the same as that of the butt-welded branch pipe platform, but its branch connection adopts threaded connection and does not need to be welded. There are two pressure classes of 3000 # and 6000 # for threaded branch pipe.
4. Mitered branch pipe is used for 45 ° branch. Butt welding, socket welding and thread connection can be adopted for connection with branch pipe.
5. Elbow olets are used to provide branch connections on long radius elbows or short radius elbows. Butt welding, socket welding and thread connection can be adopted for connection with branch pipe.
6. Spoolets are often used for valve installation and exhaust. There are two grades of thickness, XS and XXS, and the length is from 3.1/2 inch to 6.1/2 inch. The end is socket or external thread.
7. The shape of embedded pipe base is wavy, and it is reinforced as a whole. Butt-welding connection with branch pipe is commonly used for low-pressure pipeline.
