Stainless Steel SWEEPOLET High Pressure Fittings With SCH120 Wall Thickness
Product Information
· Function: The socket-welding coupling is designed to join two pipes of the same size in a socket welding system.
· Material: Typically made from stainless steel, carbon steel, or other materials suitable for high-temperature and high-pressure applications.
· Design: Features a socket on each end to accommodate the pipe ends for welding, providing a strong and leak-resistant connection.
· Installation: Pipes are inserted into the sockets of the coupling and welded to create a secure joint.
· Applications: Widely used in industries such as petrochemical, chemical, and oil and gas for connecting pipes in high-pressure systems.
· Advantages:
o Strength: Provides a durable and reliable connection between pipes.
o Leak Resistance: Ensures a tight seal to prevent leaks in the system.
o Easy Installation: Socket welding allows for a straightforward and efficient joining process.

Note:
- Where a ellipsis(﹍)appears in the table, there is no requirement and the element need to be analyzed for or reported
- The method of analysis for nitrogen shall be a matter of agreement between the purchaser and manufacturer
- Columbium 0.10-0.30%; Vanadium 0.10-0.30%.
- For small diameter or thin walls, or both, where many drawing passes are required, a carbon maximum of 0.04% is necessary in grades TP304L and TP316L. Small outside diameter tubes are defined as those less than 0.500in.(23.7mm) in outside diameter and light wall tubes as those less than 0.049in.(1.24mm) in average wall thickness
