Seamless tube for high temperature and high pressure service

Date:2018-07-02    View:731      Tag:Seamless tube for high temperature and high pressure service

The seamless high temperature service pipe used for high temperature and high pressure service is usually considered as a heat exchange tube running at 400 degrees Celsius to 1100 degrees Celsius.

High temperature service alloy steel tubes are called chromium molybdenum tubes. There are basically two types of high temperature steel pipes: 1. high temperature carbon steel tubes and 2. super  alloy steel pipe.


High Temperature Carbon Steel tube

ASTM A179, A192A210 specification covers Carbon Steel Seamless tube for high-temperature service. These pipe are used heat exchangers, condensers, High Temperature Material should furnish to Specification A 530.

  • GB5310-2008 is applicable to seamless tubes for making steam boiler whose pressure is high or higher and seamless tubes used as pipelines.
  • ASTM A179 / A179M - 90a Standard Specification for Seamless Cold-Drawn Low-Carbon Steel Heat-Exchanger and Condenser Tubes
  • ASTM A192 / A192M Standard Specification for Seamless Carbon Steel Boiler Tubes for High-Pressure Service
  • ASTM A210/ASME SA210 Standard Specification for Seamless Medium-Carbon Steel Boiler and Superheater Tubes.
High Temperature Alloy Steel tube

ASTM A213, A209 specification covers Alloy Steel Seamless tube for high temperature service. These tube are suitable for bending and similar forming operations, and for fusion welding at high temperatures. High Temperature Alloy Steel tube are also considered as low Alloy Chrome Moly grades.

  • ASTM/ASME A/SA213 Gr. T2, T5, T5b, T5c, T11, T12, T17, T21, T22, T9, T91
  • ASTM/ASME A/SA335 Gr. P1, P2, P5, P11, P12, P22
  • EN10216-2 Gr. 10CrMo9-10,13CrMo4-5,EN10216-2,P195GH,P235GH,P265GH 
High Temperature Stainless Steel tube

High temperature stainless steel tubing maintain their mechanical properties when exposed to elevated temperatures on either a short- or long-term basis.
