Specification

Introduction of Large Diameter Steel Pipe


Large diameter stainless steel pipes (JIS G3468 & CNS 13517) refer to any pipes with an outer diameter between 165mm to 1016mm.
 

We carry a variety of JIS G3468 and CNS 13517 as follows.

 

SUS304TPY, SUS316TPY(refer JIS G3468)

304TPY, 316TPY, 304LTPY, 316LTPY(refer CNS 13517)

 

Large diameter steel pipes are popular for their resistance to corrosion and can be used in low or high temperatures, making it ideal for fire fighting.

Large diameter steel pipes are also used in various industries such as food processing, fabrication, oil and gas, chemical, plumbing, general purpose applications, heating, water supply, power plants, and paper and pulp industries.

 
  • High tolerance to low or high temperatures.
  • Ability to withstand high pressure.
  • Durable stability.
  • Rust, corrosion, and chemical resistance.
  • Easy to clean and does not tarnish.
