321 stainless steel pipe has good processing and welding properties, making cutting, bending, welding and other processing operations easy to perform. Besides, it has superior mechanical properties such as tensile strength, flexural strength and elongation, and can meet the requirements of use in various environments. Because 321 stainless steel pipes have excellent corrosion resistance and high temperature performance, they are commonly seen in petroleum, chemical industry, aviation, aerospace. Since the production process of petroleum and chemical industries involves a large amount of corrosive media such as acids, alkalis, and salts, 321 stainless steel pipes can effectively cope with the corrosion of these media and ensure the stable operation of the equipment. 321 stainless steel pipe has become one of the important structural materials in the aviation and aerospace fields.
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.
