We produce large diameter Thin-walled stainless steel pipes common specifications: 219.1 mm * 3.76mm, 273.1mm * 4.19mm, 323.9mm * 4.57mm, 355.6 mm * 4.78mm, 406.4mm * 4.78mm, 457.2 mm * 4.78mm, 508mm * 5.54mm, 558.8 mm * 5.54mm, 609.6 mm * 6.35mm, 660.4mm * 7.92mm, 711.2mm * 7.92mm more commonly used in the specifications of the American standard, some standard specifications of the Japanese standard of GB have mold.Such as non-standard, custom mold production.Such large diameter Thin-walled stainless steel pipes in early 2009, we started to develop large volume production starting with the end of the year, 11-year company manufacturing grades: 0Cr18Ni9 Specifications: 630mm * 6.5mm large diameter thin-walled stainless steel pipe (seamless Production), the national oil drilling and refining equipment of Quality Supervision and Inspection Center of Special Equipment type test certificate number: TSX71004320110063, the current in large diameter thin-walled stainless steel pipe (seamless) are already quite mature, especially in outer diameter and far more than the standard control of wall thickness tolerance GB GB | T14976, 14975,13296, American Standard ASTM A312 A213, the European standard EN-10216-05 D3 \ T3 standards.
TP 310, Stainless steel 310 is a combination, of good strength and corrosion, resistance in temperatures up to, 1149°C (2100°F). The high, chromium and nickel contents, give the steel excellent oxidation, resistance. 310 is also very ductile,, and has good weldability, enabling its widespread usage in, many applications. Stainless steel, 310S contains less carbon than, 310 to minimize carbide, precipitation.
Type 310S may be, used in atmospheres containing, moderate amounts of sulfur, because of high chromium and, medium nickel contents. It is not, usually recommended for liquid, quenching., Main Application: paper, production plant, heat recuperator, tubing, combustion chambers,, molten salt applications, thermo, wells, equipment to handle, sulfite liquors and gas turbines,, furnace parts, oil burner parts,, welding filler wire and electrodes.
TP 316 TP 316Ti, Stainless steel 316 is an austenitic, grade second only to 304 in, commercial importance. Type 316, contains molybdenum that gives, it improved corrosion resistance,, increased strength at elevated, temperatures and resistance to, pitting from chloride ion solutions., It has good resistance to oxidation, up to 900°C (1650°F). Type 316, has variety of uses especially in, marine applications due to the, materials high corrosion resistance., Type 316H has carbon content, between 0.04% - 0.10%.
This, makes the steel more suitable for, use in applications where elevated, temperatures are present. 316H, is sometimes used for structural, and pressure containing, applications at temperatures, above about 500°C (900°F)., Type 316L has the same,
TP 304, Stainless steel 304 is an, austenitic grade that can be, severely deep drawn. This, property has resulted in 304, being the dominant grade used, in applications like sinks and, saucepans.
Type 304L is, probably the world’s most, common stainless steel. The L, stands for Low and refers to the, carbon content. 0.035% is the, maximum allowable carbon, content in 304L. Low carbon, content ensures better ductility, and avoids the intergranular, corrosion. Type 304H is austenitic, chromium-nickel steel alloy with, high carbon content, which, delivers increased, tensile and, yield strength.
The H in 304H, stands for High carbon content., 304H must contain carbon, between 0.04% - 0.10%., It is used where elevated, temperatures are present., Main Application: pressure vessels,, oil refining, heat exchangers,, pipelines and condensers,, chemical equipment, brewery,, dairy, food and pharmaceutical, production equipment.
Main steel tube grade: a53-a, a53-b etc. Other grade can also be provided after consulting with acustomers.
