Stainless Steel Forged Pipe Welding Neck Flange Manufacturing
Precision-forged stainless steel welding neck flanges for high-pressure piping. Tapered hub ensures smooth stress transfer and leak-tight, low-turbulence flow. ASME/DIN sizes, RF/RTJ faces, CNC-machined, tested, and traceable—built for oil & gas, chemical, power, and marine.
Engineered for dependability popular piping systems, our Stainless-steel Forged Welding Neck Flanges provide leak-resistant, high-integrity links from plant to pipe. Precision-forged from premium stainless grades (304/304L, 316/316L, 321, 347, Duplex, Super Duplex), each flange features a conical hub that transfers stress smoothly to the pipeline, lessening turbulence, vibration, and tiredness.
Produced to ASME/ANSI B16.5, B16.47 Collection A/B, and MSS-SP-44 requirements with PN/CL 150– 2500 pressure courses, we offer sizes from 1/2″ to 48″ (DN15– DN1200) with increased face (RF), ring-type joint (RTJ), and level face (FF) options. Heat-treatment and normalized building generate a thick, consistent grain structure; CNC machining holds tight tolerances on bore, hub, and gasket surfaces for repeatable area fit-up.
Every flange is 100% dimensionally checked and PMI-verified, with ultrasonic/MPI screening on request. Surface surfaces satisfy 125– 63 μin Ra for gasket seats; serrated, stock, and smooth surfaces are readily available. Mill examination certifications (EN 10204 3.1/ 3.2), NACE MR0175/ISO 15156 conformity, and PED/AD 2000 documentation assistance international implementation.
Applications span oil & gas, chemical processing, desalination, power generation, marine, and heating and cooling. Deterioration resistance, temperature level stability, and weldability make these flanges suitable for corrosive media, high-temperature service, and cyclic tons.
Personalization consists of bespoke bores, long welding neck (LWN) and decreasing types, heavy-wall centers, special exploration (ASME/EN/BS/ DIN/JIS), corrosion-resistant overlays, and anti-galling finishings. Packaging is anti-corrosion covered, palletized, and barcoded for traceability, with brief lead times on conventional sizes and fast manufacturing for task call-offs.
Choose our stainless steel created welding neck flanges to lower downtime, streamline installation, and prolong property life– backed by strenuous QA, receptive design support, and constant, on-spec shipment.
Companion with a manufacturer that comprehends job facts: exact scheduling, thorough documentation packs, and batch-level traceability. From prototype to volume, our active cells, stocked billets, and automated examination assistance you fulfill budgets without jeopardizing security, compliance, or performance– every flange, whenever.
