303 Stainless Steel Pipe
Excellent Machinability: Sulfur or selenium additives significantly improve chip breaking and surface finish during turning, drilling, and threading operations.
Moderate Corrosion Resistance: Suitable for atmospheric, freshwater, and mild chemical exposures typical of indoor and general industrial use.
Non-Magnetic Properties: Maintains austenitic non-magnetic characteristics in the annealed condition.
Good Strength and Formability: Can be cold-formed and welded with appropriate techniques, though machinability is the primary advantage.
Applications
Ideal for machined fittings, valve bodies, pump components, fasteners, instrument tubing, and automated production parts where high-speed machining is required.
We provide pipes in various diameters, wall thicknesses, and lengths, with options for cutting, threading, polishing, and surface finishing. Full material certification compliant with ASTM A582, EN 10088-3, JIS G4303, and related standards is included to ensure quality and performance consistency.
Our stainless steel pipes are manufactured from premium austenitic, duplex, and ferritic grades (304, 316, 310, 2205, 430, etc.), ensuring exceptional corrosion resistance, high-temperature stability, and mechanical strength. Available in seamless and welded types, these pipes comply with ASTM A312, ASTM A269, EN 10216, and other international standards. Customization options include varying dimensions, surface finishes (polished, brushed, pickled), and end treatments (beveled, threaded, capped). Ideal for chemical processing, oil and gas, food and beverage, and architectural applications.
Our state-of-the-art production line integrates precision piercing, cold drawing, and automated TIG welding processes, supported by solid-solution treatment and pickling passivation systems. Advanced eddy current testing, hydrostatic pressure testing, and laser sizing equipment ensure dimensional accuracy and defect-free quality. The fully digitized workshop enables real-time monitoring of critical parameters (temperature tolerance ±5°C, wall thickness deviation ≤±0.1mm), delivering pipes with consistent microstructure and superior performance for high-pressure and corrosive environments.
In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.
Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
