B16.5 1500lbs 2500lbs A694 F60 F65 F70 Type Rtj Swivel Flange

Manufactured in strict accordance with ASME B16.5 standard, this product covers high-pressure working conditions of Class 1500 and Class 2500. It is forged from high-yield ASTM A694 grades F60, F65 and F70, matching X60/X65/X70 line pipe steel with outstanding mechanical properties and meeting NACE anti-sulfide service requirements.It adopts RTJ ring joint face for metal-to-metal hard sealing, which resists high temperature, high pressure and vibration to eliminate leakage of high-pressure media. The swivel design allows free alignment of bolt holes, greatly simplifying on-site pipe fitting and installation for complex pipeline layouts.Fully forged as a single piece, the product undergoes quenching and tempering heat treatment and passes full non-destructive testing with high dimensional accuracy. Available in sizes NPS 1/2 to 24 and compatible with octagonal and oval metal ring gaskets, it balances pressure tightness and easy assembly, serving as a reliable connecting component for harsh environments including oil & gas gathering, offshore platforms, high-pressure chemical plants and long-distance transmission pipelines.
