Zhejiang Mingxin Stainless Steel Co., Ltd. applies hydrostatic testing as part of its quality control process. Each tube undergoes hydrostatic testing before shipment, using testers and other professional equipment to verify sealing performance under rated pressure. This testing is combined with eddy current flaw detection, ultrasonic testing, and tensile testing to ensure products meet applicable standards. The company’s seamless pipes, bright annealing tubes, and heat exchanger tubes are manufactured to [...]
In the chemical fiber industry, equipment such as polymerization reactors, acetic acid recovery towers, and heat exchangers are constantly exposed to corrosive media like acetic acid and caprolactam under high temperature and pressure. Zhejiang Mingxin Stainless Steel Co., Ltd. supplies 304 and 316L stainless steel seamless pipes and heat exchanger tubes tailored for polyester, nylon, and viscose fiber production. 304 stainless steel is suitable for cooling equipment in [...]
Zhejiang Mingxin Stainless Steel Co., Ltd., established in 2016, has gradually built a multi-material product system covering austenitic stainless steel, duplex stainless steel, and nickel-based alloys. 304 stainless steel offers good corrosion resistance for general industrial applications; 316L stainless steel, with added molybdenum, provides better resistance to chloride corrosion, making it suitable for coastal chemical and marine engineering. Duplex stainless steel combines austenitic and ferritic phases, offering stable performance in [...]
Zhejiang Mingxin Stainless Steel Co., Ltd. has developed a stable supply chain for its stainless steel seamless pipes and heat exchanger tubes.
