ASTM A182 F316/F316L Stainless Steel Fitting Weldolet BW MSS-SP-97

What is weldolet?

A Weldolet is a type of branch connection fitting used in piping systems to create a secure, high-integrity outlet from a main run pipe. It is a welded reinforcement fitting designed according to standards like MSS-SP-97. The fitting is welded directly onto the main pipe, and the branch pipe is then welded to the outlet of the Weldolet. This design provides significant structural reinforcement, minimizes stress concentration, and ensures a smooth flow transition. Weldolets are particularly valued in critical applications—such as high-pressure, high-temperature, or corrosive service—where system integrity and reliability are paramount. The use of materials like ASTM A182 F316/F316L stainless steel further enhances their corrosion resistance and durability in demanding environments.
