ANSI B16.5 F304 CL150 RF Socket Weld Flange is inch-size closed forged socket weld flange, dedicated for American-standard refinery, gas station, petrochemical small-bore flammable medium piping. Exclusive overseas energy project advantages: full ANSI inch socket size, anti-fatigue reinforced weld groove, oil-resistant double anti-corrosion layer, ATEX hazardous zone certification, low assembly tolerance, compatible with US standard seamless oil pipe directly.
CL150 pound class rated working pressure 2.07MPa, perfectly adapted for small-bore natural gas, diesel, crude oil flammable medium conveying. Closed die forging compact metal texture, improve socket shear resistance, avoid socket cracking under pipeline vibration and pressure fluctuation. Reinforced fillet weld groove design, increase welding fusion area, strengthen joint tensile strength, suitable for long-term vibration oilfield pipeline operation without weld joint fracture.
Integral stress relief heat treatment eliminates forging residual stress, stabilizing socket size under temperature alternation. Double anti-corrosion treatment: passivation base + oil-proof surface coating, resisting long-term hydrocarbon oil soaking corrosion. Inch precision CNC socket machining, match NPS standard oil pipe end without field reaming. 1/2''-2'' oilfield inch small bore in stock. Support weld groove anti-rust customization. Passed ultrasonic flaw detection. 16-month oil&gas explosion-proof warranty, complete ANSI customs clearance certificates provided.
Core Product Advantages:1.Full inch socket interchangeable with US oil pipe;2.Reinforced weld groove anti-joint fracture;3.Double anti-corrosion oil soaking resistant;4.Stable size after stress relief treatment;5.Low tolerance easy on-site oilfield assembly

11：What industries can Shangdian Flange serve?
—Flanges and pipe fittings are core connecting components for industrial piping systems, widely used in chemical engineering, pressure vessel equipment, pharmaceutical clean piping, semiconductor high-purity piping, data center liquid cooling systems, LNG (liquefied natural gas), nuclear power, marine & offshore engineering, power station boilers, metallurgy, water treatment, papermaking and many other sectors.
— Shangdian Flange focuses on two core product lines:
Industrial heavy-duty flanges and pipe fittings, designed for working conditions requiring high strength, resistance to high temperature, high pressure and severe corrosion;
Sanitary clean-type flanges and pipe fittings, applied to scenarios demanding high precision and high cleanliness.
We specialize in custom solutions for extreme operating environments, including heavily corrosive media in chemical plants, pharmaceutical clean pipelines, semiconductor high-purity systems, liquid cooling systems for data centers and energy storage facilities. We have mature manufacturing experience covering materials from nickel-based alloys and Hastelloy to super duplex stainless steel.
