ASTM A182 F304 F304L MSS SP-97 Stainless Steel Weldolet valve Instruments Pipeline
What is Weldolet?
Weldolet is also called branch pipe seat, saddle seat, saddle type pipe joint. Mainly used for branch connection reinforcement type pipe fittings, instead of using reducer tee, reinforcement plate, reinforced pipe section and other branch connection type, with e and reliable, reduce the cost, simple construction, improve the media flow channel, series standardization, design and selection of convenient and other outstanding advantages, especially in high pressure, high temperature, large diameter, thick wall pipeline is increasingly used, replacing the traditional branch connection method. The body of the branch pipe table is made of high-quality forgings, and the materials used are the same as those of the pipe, such as carbon steel, alloy steel and stainless steel. The branch pipe seat and the main pipe are welded, and the branch pipe or other pipes (such as short pipes, silk plug, etc.), instruments, valves are connected with butt welding connection, socket welding connection, threaded connection three types. The common manufacturing execution standards of branch pipe table are MSS SP-97, GB/T19326 and other standards.
