Stainless Steel Threaded Fittings Factory Distributors China

Engineered for requiring flow systems, our Seamless Threaded Pipe Fittings supply leak-tight efficiency, lengthy service life, and quick installment throughout oil & gas, chemical processing, power generation, COOLING AND HEATING, water supply, and general commercial applications. Produced in an up and down integrated factory, each fitting starts with premium seamless hollows and close-grain forgings, then moves via precision CNC machining to attain concentric, burr-free NPT, BSPT, and BSPP strings. Dimensional precision is verified with calibrated evaluates, while surface area coatings are regulated for smooth assembly and trustworthy sealing.

Offered in carbon steel, stainless steel (304/304L, 316/316L), and pick alloy grades, our variety covers sizes 1/8 ″– 4 ″ and pressure courses 2000/3000/6000. Choose from elbow joints, tees, full and half couplings, unions, caps, plugs, crosses, bushings, and reducing adapters to build durable, modular piping formats. Heat therapy– stabilizing, satiating and solidifying, or service annealing– optimizes grain framework for durability and corrosion resistance. Every phase follows ISO 9001 quality monitoring and ASME B16.11/ ASTM material criteria, backed by 100% visual and string inspection, PMI material verification, firmness checks, and hydrostatic or air-tightness screening with deducible warm numbers.

To deal with deterioration in storage space and service, installations are cleaned up, rust-inhibited, and readily available with black oxide, zinc plating, electroless nickel, or stainless passivation; oxygen-service variants ship oil-free for instrumentation duty. Chamfered lead-ins speed positioning, while hex and shoulder features enable safe wrench-tight setting up in tight shelfs. Limited machining resistances decrease rework, and optimized wall density protects circulation area and mechanical toughness under pressure and vibration.

We support rapid OEM/ODM modification– special string types, non-standard lengths, bespoke markings, and private-label product packaging– enabled by flexible manufacturing cells and on-hand raw stock for short preparations. Each order ships with mill certifications, examination records, and export-ready packaging (poly bags, inner containers, fumigation-free crates). Select our Seamless Threaded Pipe Fittings to reduce installation time, reduce leakage risk, and keep systems running securely and efficiently– project after job.
