Updated pressure-temperature rating alignments with ASME B16.5 and B16.34.
updated requirements for essential dimensions, materials, and testing for both 90° and 45° branch connections.
The MSS SP-97 standard establishes requirements for forged branch outlet fittings with butt-welding, socket-welding, and threaded ends. These fittings are designed to provide a 90-degree branch connection from a main run pipe (the "header"). Mss Sp-97 2019 Free Download Pdf

Legally, no.
One of the primary focuses of MSS SP-97 is the reinforcement of the branch connection. Unlike standard tees, these fittings are designed to provide the necessary structural integrity without the need for additional reinforcement pads. The standard specifies the exact dimensions and tolerances required for various pressure classes, ranging from 2000# to 9000#, ensuring compatibility with both ASME B16.11 and ASME B31.3 piping codes.
Better coverage for larger diameter headers.
