ANSI B16.5 F304 CL150 RF Loose Lap Joint Flange is inch-size closed forged loose flange, dedicated for American-standard refinery, gas station, chemical plant adjustable oil and gas piping. Exclusive overseas energy project advantages: full ANSI inch dimension, anti-vibration gap design, oil-resistant double anti-corrosion layer, ATEX explosion-proof qualified, offset-angle installation adaptable, easy cross-site bolt matching for overseas EPC projects.
CL150 pound class rated working pressure 2.07MPa, suitable for low-medium pressure natural gas, diesel, light crude oil flammable medium conveying. Closed die forging densifies flange ring internal structure, improves ring surface impact resistance, adapts pipeline micro-vibration of oilfield station. Reserved tiny movable gap between flange ring and stub end, offsets pipeline thermal expansion displacement, avoiding flange bolt fatigue fracture under temperature alternation.
Double anti-corrosion treatment: passivation base + hydrocarbon oil-proof coating, resisting long-term fuel soaking corrosion. Full inch standard inner bore and bolt hole, directly matched NPS pipe and ANSI stub end without field cutting modification. Reinforced edge thickness prevents edge crack during high torque bolt fastening. 1/2''-24'' inch full size in stock. Support anti-vibration gap customization, flange surface logo engraving. Passed ultrasonic flaw detection. 16-month oil&gas explosion-proof warranty, complete ANSI customs clearance certificates provided.
Core Product Advantages:1.Full inch size interchangeable with US oil pipe fittings;2.Movable gap offset pipe thermal expansion;3.Double oil-proof coating fuel corrosion resistant;4.Explosion-proof certified for hazardous oil-gas zone;5.Adapt skew pipe installation, reduce site construction difficulty
