Best quality 40×40 Square Tube - Boiler Seamless Steel Tube – XUANZE
Mainly used to manufacture high-quality carbon structural steel and alloy structural steel seamless steel pipes for steam boiler pipes with high pressure and above.
These boiler tubes often work under high temperature and high pressure, and the tubes will also undergo oxidation and corrosion under the action of high temperature flue gas and water vapor.
Therefore, steel pipes are required to have high endurance strength, high oxidation resistance, and good structural stability.
Steel pipe material category: Carbon steel and Alloy steel.
20G, ASTM A179&192, ST52, 12Cr1MoV,etc…
20G SEAMLESS STEEL PIPE
Special pipe for boiler pressure vessel.
Special tube for heat exchanger.
In addition to ensuring chemical composition and mechanical properties, high-pressure boiler pipes must be subjected to hydrostatic tests, flaring and flattening test.
