ANSI B16.5 ASTM A182 F304 CL150 RF Welding Neck Flange is inch-size hot forged stainless steel butt weld flange, designed for American-standard oil, gas, petrochemical and overseas engineering piping. Exclusive advantages for overseas project: strict ANSI inch dimension standard, stress-relief annealing anti-fatigue, high temperature oxidation resistance, full penetration weld anti-leakage, interchangeable with US-standard pipe fittings without site modification.
CL150 pound-class pressure bears 2.07MPa rated working pressure, adapt mild corrosive crude oil, natural gas, diesel medium long-term conveying. After professional stress relief annealing, the whole flange eliminates forging internal stress, resistant to high-low temperature alternating fatigue, no neck fracture under refinery seasonal temperature change. Tapered hub smooth inner bore reduces fluid turbulence, lowers medium erosion on welding seam, prolong pipeline whole service life.
Ultra-precision inch hole drilling, 100% matched with ANSI bolts, valves and mating flanges, save on-site processing cost. Matte anti-oil surface treatment + passivation double anti-corrosion, resistant to hydrocarbon medium corrosion. Every piece passes ultrasonic flaw detection and hardness test. Size 1/2''-24'' oilfield inch size in stock. Factory support custom inch bevel, logo marking, special gasket face processing. FOB port delivery available, 16-month oil&gas project warranty, complete ANSI inspection documents provided.
