1. Butt weldedolet is the most common branch connection. It is made of bevelled end and welded with straight pipe, so it is considered as a butt welded pipe fitting. The design of the butt weldedolet minimizes stress concentration and provides overall reinforcement. There are three pressure levels of STD, XS and Sch160 for butt welded branch pipes.
2. The base of the socketolet is the same as that of the butt welded branch pipe platform, but its branch connections are welded by socket. There are two pressure levels of 3000# and 6000#.
3. The base of the threadedolet is the same as that of the butt weldedolet, but its branch connection is threaded and does not require welding. There are two pressure levels of 3000# and 6000#.
4. Latrolet for 45° branch. The branch pipe can be connected by butt welding, socket welding and thread connection.
5. Elbolet is used to provide branch connections on long radius elbows or short radius elbows. The branch pipe can be connected by butt welding, socket welding and thread connection.
6. Short pipe branch table is often used for valve installation and exhaust. There are two grades of thickness, XS and XXS, from 3.1/2 "to 6.1/2" in length, with a jack or external thread at the end.
7, the embedded tube seat shape is wavy, the overall reinforcement. It is butt welded with branch pipe and is often used for low pressure pipe.
