ASTM A105 Forged CL150 ANSI Plate Flange is American standard die-forged flat welding flange manufactured per ANSI B16.5 industrial standard, customized for onshore petrochemical, natural gas and fuel oil conveying piping systems. Different from ordinary rolled plate flanges, this flange adopts closed die hot forging integral molding, after high-temperature stress relief heat treatment, the internal metal grain is compact and uniform, owning excellent high-temperature resistance, pressure resistance and anti-brittle performance, adapting outdoor temperature alternation and harsh industrial working conditions.
Class150 pound-level pressure rating matches US standard piping load standard, maximum working pressure reaches 2.07MPa at normal temperature, RF raised face sealing design compatible with ANSI standard spiral wound gaskets and rubber gaskets. Adopt precision CNC inch-size drilling, unified US standard bolt diameter and hole spacing, interchangeable with all ANSI standard pipe fittings, valves and pipeline accessories. Each batch provides official ASTM A105 MTC mill test certificate, chemical composition and mechanical strength data traceable.
Surface finished with high-temperature anti-rust black painting, paint layer firm adhesion, resistant to outdoor wind and rain erosion, no paint peeling during conventional field welding. Size range 1/2Inch-24Inch(DN15-DN600), full inch specification in stock. Strict third-party ultrasonic flaw detection to check internal forging crack, ensure zero defect finished product. Suitable for onshore crude oil pipeline, city natural gas trunk pipe, petrochemical workshop process pipe, American-standard industrial equipment interface connection. Support FOB port delivery, mixed container loading, 14-month industrial heavy-duty quality warranty, third-party inspection acceptable before shipment.
