Who We Are
Wenzhou Xinzhe Tech Co., Ltd. is a China-based stockist and supplier of seamless stainless steel, duplex, super duplex, and nickel alloy pipes and tubes, founded in 2019 in Wenzhou, Zhejiang Province.
Backed by direct manufacturing capacity through our affiliated factory, Zhejiang Xintongda Special Steel Manufacturing Co., Ltd. (XTD Special Steel), Xinzhe combines the flexibility of a trading and stocking company with the production control, quality traceability, and cost advantages of a mill-direct source.
Manufacturing Strength Behind the Stock
Because Xinzhe's supply is rooted in XTD Special Steel's production facility, every order can be backed by full production traceability — from raw material certification through final testing — rather than relying on third-party sourcing with limited visibility. This is a key point of difference versus typical trading companies that resell inventory of unknown or mixed origin.
Product Range
Seamless stainless steel pipes & tubes; duplex & super duplex stainless steel (S31803/S32205, S32750/S32760); nickel alloys including Inconel (600/625/825), Incoloy (800/825/925), Hastelloy (C276/C22), Monel (400) and pure nickel (200/201).
Product forms: boiler tubes, heat exchanger tubes, U-tubes, condenser tubes, and high-pressure & heavy-wall pipe for demanding service conditions.
Quality Assurance
Every order is supported by complete mill test certificates and full production traceability. QC checkpoints are applied at each stage — raw material inspection, dimensional control, mechanical & corrosion testing, and final inspection. Third-party inspection (SGS, BV, or client-nominated bodies) is welcomed prior to shipment upon request.
