Product Specification Summary

This MSS SP-97 A182 F22 CL3 extended branch outlet set is built on a 6 inch run pipe, with two different branch take-off sizes: 1 inch and 1-1/2 inch, both to XS / Schedule 80 wall thickness. Unlike standard short branch outlets, this extended length design gives extra clearance around insulation, support brackets and instrument hook-ups, a practical detail frequently specified for refinery pipe racks in Singapore. Every MSS SP-97 A182 F22 CL3 extended branch outlet follows the area reinforcement rules defined in MSS SP-97, removing the need for reinforcing pads at the branch intersection.

Made from ASTM A182 F22 Class 3 chromium-molybdenum alloy steel, each extended branch outlet is controlled carefully for hardness and microstructure to satisfy NACE sour service requirements. F22 alloy maintains stable mechanical strength under elevated temperature, while the NACE restriction guards against sulphide stress cracking when H₂S is present in process media. Our QC team reviewed forging records, dimensional checks and material test reports to confirm the fittings meet both the standard and the client’s project inspection matrix.

Both units are finished with plain butt-weld ends for direct field welding to matching branch piping. The high Class 6000 rating makes these MSS SP-97 A182 F22 CL3 extended branch outlets suitable for high-pressure take-offs used for drains, vents, sampling points and instrument taps. For Singapore refinery and petrochemical projects, sour-service alloy branch connections demand tighter traceability than ordinary carbon steel fittings, and we package all certification documents together for third-party review on site.

Haihao Group supplies MSS SP-97 forged branch outlets, reinforced take-off fittings and alloy piping components for Singapore and Southeast Asia energy facilities. We can deliver extended outlet variants, butt-weld, socket weld and threaded styles in F11, F22, F5, F9 and other alloy grades with NACE compliance. If you need reinforced branch connections for high-temperature or sour process lines, send your run and branch sizes, class and service requirements for a quotation.
