ANSI B16.5 F304 CL150 RF Threaded Flange is inch-size hot-forged NPT screwed flange, specially developed for American-standard oil, gas, petrochemical explosion-proof piping systems. Exclusive overseas project advantages: full ANSI inch thread dimension, ATEX explosion-proof grade, oil-resistant double anti-corrosion coating, anti-fatigue thread tooth, no welding fire risk, full interchangeable with US standard threaded pipe fittings.
CL150 pound-class pressure rated 2.07MPa working pressure, perfectly adapted for low-medium pressure crude oil, natural gas, diesel flammable medium conveying. Weld-free threaded assembly eliminates open fire construction risk, the top priority for refinery, gas station ATEX hazardous zone construction. After integral stress relief treatment, flange disc and thread base eliminate forging internal stress, thread tooth resistant to cyclic vibration fatigue, long-term gas pipeline operation no thread loosening leakage.
Inch standard NPT thread one-time CNC forming, strict tooth tolerance, match ANSI male thread pipe, thread valve directly without field rethreading. Matte oil-proof surface + passivation double anti-corrosion layer, resist hydrocarbon oil medium soaking corrosion. Every piece passed thread gauging, hardness test and ultrasonic inspection. 1/2''-24'' oilfield inch size in stock. Factory custom thread seal groove, anti-loose thread knurling, logo marking. FOB port delivery available, 16-month oil&gas explosion-proof warranty, complete ANSI clearance documents provided.
