Marine Pipe Fitting

Our factory is a professional manufacturer with over 30 years experiences in pipe fittings, which mainly produces steel BW seamless and welded elbow, tee, cross, reducer, big -R-bend, cap, stub end, forged flange, socket-welding and thread fitting, and induction heating bend, etc. in materials of carbon steel and low temperature steel, alloy steel, stainless steel, duplex stainless steel, titanium and nickel base alloy, etc.; the products are widely used in the process piping and power piping in petroleum, chemical, electric power, shipbuilding, natural gas,nuclear power and coal chemical industries, as well as in piping for utilities.

Our piping fittings can be provided with CE/PED Certificate, API
Certificate and classification society certificates as BV, CCS, ABS, DNV, LR for factory approval and design approval.

  • Size range: 1/2”-96” (DN15-DN2400), wall thickness 1mm-80mm.

  • Pressure grade SCH5S ~ SCH160,

  • Standard: GB、HG、HGJ、SH、SY、DL, ANSI、JIS、DIN

  • Customs-made available as per customer’s drawing.

Focus on technological innovation and brand building in recent years, our factory has developed over 20 hi-tech products, such as duplex stainless steel pipe fitting, nickel alloy pipe fitting, double metal composite elbow, nuclear class stainless steel fitting, alloy steel high press seamless elbow by hot pushing, titanium and titanium alloy pipe fitting, and high pressure hydrogen stainless steel pipe fitting, including more than 10 proprietary intellectual property rights.

Depending on advanced technological equipment, sound quality management system, perfect detection means, reliable quality, and circumspect after-sales service,our factory has made long cooperation relationship with domestic companies including Sino-foreign joint venture in fields as chemical, petroleum, natural gas, electric power and nuclear power, shipbuilding etc. and also cooperated with some great designing institutes.
