2025-08-08
Steel jacketed insulated steel pipes for heating networks are mainly used in high-temperature industries and are suitable for transporting steam or other media at pressures up to 2.5MPa and temperatures below 350 degrees Celsius.
Steel jacket insulated steel pipes for heating networks are mainly used in high-temperature industries and are suitable for transporting steam or other media at pressures up to 2.5MPa and temperatures below 350 degrees Celsius.
The price of steel jacket insulated steel pipes for heating networks is relatively high, generally higher than that of ordinary polyurethane insulated steel pipes.
The working steel pipe of the steel jacket insulated steel pipe for heating networks uses seamless steel pipe, and the outer protective steel pipe uses spiral steel pipe.
1. The production of steel pipes should comply with the requirements of CJ/T3022-93 "Spiral Submerged Arc Welded Steel Pipes for Urban Heating". (Steel pipes need to be produced from rolled plates, and the rolled plate manufacturers should be Taiyuan Iron & Steel, Benxi Steel, or Anshan Steel.)
2. Steel grade: The steel used for the pipes should meet the requirements of Q235-B grade steel according to GB700 standard. The chemical composition and mechanical properties should comply with the requirements of GB700 standard.
