Instrumentation Tubing Materials

  • Our standard tubing material is 304 stainless steel and 316L stainless steel. Stainless steel is a popular choice of both tubing and fittings for its strength and durability. Stainless steel tubing is widely used for piping installations across various industries. In addition to our tubing, customers also prefer to order the related double compression tube fittings or instrumentation fittings from us.
  • While stainless steel is the preferred choice for many engineers in piping installations, there is increasing usage of high nickel containing special alloys in LNG, natural gas and petrochemical plants for specialized applications. We offer Nickel 200 tubing, Nickel 201 Tubing, Alloy 400 Tubes,  Alloy 825 tubes and Alloy 625 tubes. Generally our tubes are stocked in 6 meter random lengths, but for ease of transport,  we can also cut the tubes in half. Tube can be supplied in any length.
