Large diameter stainless steel seamless pipe is a kind of hollow section, no joints around the strip of steel. The thicker the wall thickness of the product, the more economical and practical it is, the thinner the wall thickness, its processing costs will rise substantially. The process of the product determines its limited performance. Generally, the precision of seamless steel pipe is low: uneven wall thickness, low internal surface brightness, high measuring cost, and the internal surface and pitting and black spots are not easy to remove; Its detection and shaping must be handled offline. Therefore, it embodies its superiority in high pressure, high strength and mechanical structure materials.
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.
