Stainless carbon steel composite pipe

Stainless carbon steel composite pipe

Stainless steel, with its excellent corrosion resistance, abrasion resistance, heat resistance, and its shiny, luxurious surface, and are widely used in various fields of the national economy.

Lack of limited by the resources of our NI, relies heavily on imports of stainless steel demand, the price is more expensive, the popularization and application of stainless steel to a certain extent by with constraints.

Carbon steel, especially the Q series carbon structural steel, with high bending strength, good impact resistance and anti-fatigue limit, as well as low prices, thus making it the basis of the national economic construction materials, carbon structural steel, its main elements Fe metal reactivity, oxidation in the atmosphere, it is easy to rust, let alone in a corrosive medium or special (wet, dark) environment. Year for its anti-corrosion investment as well as economic losses because of its natural corrosion, several hundred billion yuan, due to corrosion and are too numerous to lead to a major accident.

Two metal materials of stainless steel and carbon structural steel, using high-tech plastic pressure synchronous composite, composite field of new materials is a major innovation without glue pressure stainless steel composite pipe (Stainless Steel / Carbon Steel Clad Pipe) not only significantly improve the law system steel pipe surface defects and the use of performance, and both good stainless steel corrosion abrasion resistance and excellent appearance gorgeous appearance, is the perfect combination of decorative and load, energy-saving and low-cost organic unity, in line with the composite materials industry policy to develop the country, thus by all levels of government attention and support.


Material stainless steel grades:

Also known as "marine grade" stainless steel due to its increased ability to resist saltwater corrosion compared to type 304. SS316 is often used for building nuclear reprocessing plants.

  • Type 304 has slightly lower strength than 302 due to its lower carbon content.
  • Type 316/316L is a molybdenum steel possessing improved resistance to pitting by solutions containing chlorides and other halides.
  • 310S Stainless Steel has excellent resistance to oxidation under constant temperatures to 2000°F.
  • 317L Stainless Steelis a molybdenum bearing austenitic chromium nickel steel similar to type 316, except the alloy content in 317L is somewhat higher.
  • 321/321H Stainless Steel is basic type 304 modified by adding titanium in an amount at least 5 times the carbon plus nitrogen contents.
  • 410 Stainless Steel is a martensitic stainless steel which is magnetic, resists corrosion in mild environents and has fairly good ductility.
  • Duplex 2507 (UNS S32750) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed.
  • Duplex 2205 (UNS S31803), or Avesta Sheffield 2205 is a ferritic-austenitic stainless steel.
  • SUPER DUPLEX UNS S32760 - is a super duplex stainless steel, so-called due to its higher Chromium and Molybdenum content.
