ANSI B16.5 F316L CL150 RF Socket Weld Flange is an upgraded anti-corrosion version of American standard oilfield flange, aiming at the high chloride and salt content characteristics of oilfield produced water. The low-carbon molybdenum structure solves the pitting corrosion and thread seizure failure of ordinary 304 flanges in oilfield complex corrosive environments, and is the special matching fitting for overseas oilfield water injection and corrosive medium pipelines.
CL150 (2.07MPa) medium-pressure rating adapts to oilfield circulating water and corrosive crude oil mixed medium transmission. Ultra-low carbon formula avoids weld intergranular corrosion, ensuring long-term connection stability. Molybdenum element enhances chloride ion erosion resistance, effectively coping with oilfield brine and salt-containing medium scouring. Optimized anti-residue socket structure reduces corrosive medium accumulation and lowers crevice corrosion risk.
Core Selling Points
  1. Low carbon anti-weld corrosion, no brittle cracking in long-term oilfield service;

  2.  Molybdenum alloy anti-chloride pitting, exclusive for high-salt oilfield media;

  3. Oil-salt dual anti-corrosion, adapt to oil-water mixed corrosive environment;

  4. ANSI inch full standard, interchangeable with global oilfield standard fittings;

  5. Anti-vibration socket structure, stable for long-term pipeline vibration;

  6. Low maintenance rate, reduce oilfield pipeline operation cost.
