  • Stainless Steel Seamless Coiled Tube

    Stainless Steel Seamless Coiled Tube

    We have been providing the seamless coil tubes to shipbuding ,plant ,oil & gas industries. Coil tube will solve many problems. Coil tube will reduce the welding times and the problems by the bad welds. Requires less fittings and orbital welds, reducing defects and failures.

    Coil tube has better corrosion resistance than other products with good internal roughness and cleanness by applying BA heat treatment.

  • 304 / 304L Stainless Steel Seamless Tubing

    304 / 304L Stainless Steel Seamless Tubing

    304 and 304L grades of austenitic stainless steel are the most versatile and commonly used stainless steels. 304 and 304L stainless steels are variations of the 18 percent chromium – 8 percent nickel austenitic alloy.They exhibit excellent corrosion resistance to a wide range of corrosive environments.

  • 316 / 316L Stainless Steel Seamless Tubing

    316 / 316L Stainless Steel Seamless Tubing

    316/316L stainless steel is one of the more popular stainless alloys. Grades 316 and 316L stainless steel were developed to offer improved corrosion resistance compared to alloy 304/L. The increased performance of this austenitic chromium-nickel stainless steel makes it better suited for environments rich in salt air and chloride .Grade 316 is the standard molybdenum-bearing grade, second in overall volume production to 304 amongst the austenitic stainless steels.

  • Bright Annealed(BA) Seamless Tube

  • Ultra High Pressure Tube(Hydrogen)

    Ultra High Pressure Tube(Hydrogen)

    Hydrogen pipeline materials should be HR31603 or other materials that have been tested to confirm good hydrogen compatibility. When selecting austenitic stainless steel material, its nickel content should be greater than 12% and the nickel equivalent should not be less than 28.5%.

  • High Purity BPE Stainless Steel Tubing

    High Purity BPE Stainless Steel Tubing

    BPE stands  for bioprocessing equipment developed by the American Society of Mechanical Engineers (ASME). BPE establishes standards for the design of equipment used in bioprocessing, pharmaceutical and personal-care products, and other industries with strict hygienic requirements. It covers system design, materials, fabrication, inspections, cleaning and sanitization, testing, and certification.

  • Instrumentation Tube(Stainless Seamless)

    Instrumentation Tube(Stainless Seamless)

    Hydraulic & Instrumentation Tubes are important components in hydraulic and instrumentation systems to protect and partner with other components, devices or instruments to secure the safe and trouble-free operations of oil and gas plants, petrochemical processing, power generation and other critical industrial applications. Consequently, demand on the quality of tubes is very high.

  • S32750 Stainless Steel Seamless Tubing

    S32750 Stainless Steel Seamless Tubing

    Alloy 2507, with UNS number S32750, it is a two-phase alloy based on the iron-chromium-nickel system with a mixed structure of about equal proportions of austenite and ferrite. Due to the duplex phase balance, Alloy 2507 exhibits excellent resistance to general corrosion like that of austenitic stainless steels with similar alloying elements. Besides, it possesses higher tensile and yield strengths as well as significantly better chloride SCC resistance than its austenitic counterparts while maintaining better impact toughness than the ferritic counterparts.

  • SS904L AISI 904L Stainless Steel (UNS N08904)

    SS904L AISI 904L Stainless Steel (UNS N08904)

    UNS NO8904, commonly known as 904L, is a low carbon high alloy austenitic stainless steel which is widely used in applications where the corrosion properties of AISI 316L and AISI 317L are not adequate.  904L provides good chloride stress corrosion cracking resistance, pitting resistance, and general corrosion resistance superior to 316L and 317L molybdenum enhanced stainless steels.

  • Monel 400 Alloy (UNS N04400/ W.Nr. 2.4360 and 2.4361 )

    Monel 400 Alloy (UNS N04400/ W.Nr. 2.4360 and 2.4361 )

    Monel 400 alloy is a nickel copper alloy which has high strength over a wide temperature range up to 1000 F. It is regarded as being a ductile Nickel-Copper alloy with resistance to a wide variety of corrosive conditions.

  • INCOLOY 825 (UNS N08825 / NS142)

    INCOLOY 825 (UNS N08825 / NS142)

    Alloy 825 is an austenitic nickel-iron-chromium alloy also defined by additions of molybdenum, copper and titanium. It was developed to provide exceptional resistance to numerous corrosive environments, both oxidizing and reducing.
