ANSI B16.5 F304 CL150 RF Plate Flange is an American standard inch-size flat weld flange, specially designed for overseas refineries, gas stations and petrochemical explosion-proof pipeline systems. The CL150 pressure grade (2.07MPa) meets the medium-pressure load requirements of flammable and explosive oil and gas media. The standard plate flat weld structure features simple on-site assembly, low welding fire risk, and fully complies with ATEX explosion-proof standards for hazardous area construction.
Adopting closed die forging and integral stamping process, the product has dense internal metal structure, high overall rigidity and excellent vibration resistance, adapting to long-term micro-vibration working conditions of oil and gas pipelines. Precision inch-size processing fully matches NPS American standard oil and gas pipelines without on-site cutting or modification. Special oil-proof passivation treatment resists long-term hydrocarbon medium soaking corrosion, preventing flange sticking and sealing failure in oil and gas working environments.
