Supplier of DIN 17175 St52.8 Seamless Tubes

As a professional supplier of st52.8 seamless pipe, Rainbow steel industry will provide the price of st52.8 seamless pipe and the processing service of st52.8 seamless pipe. Our DIN 17175 st52.8 seamless pipes and tubes are used for boiler installation, high pressure pipes and tank structures, as well as special machinery for high temperature and high pressure equipment.



"ST" refers to carbon steel pipes of general construction (i.e. ordinary carbon steel pipes rather than low alloy steel pipes), which are not intended to undergo heat treatment (i.e. rolling operation in addition to heat treatment naturally occurring during high temperature cooling).


Din 17175 st52.8 seamless boiler tube is widely used in boiler industry, petroleum, chemical industry, chemical fiber, metallurgy, medicine, machinery, paper making, heat preservation, refrigeration, mechanical equipment, food, electricity, water, construction, aviation, aerospace, ship, shipbuilding, environmental protection and boiler heat exchanger.


St52.8 seamless tube is specially used for heating surface tube of medium and low pressure boiler (working pressure not higher than 5.88 MPa, working temperature lower than 450 ℃). The seamless boiler tube can also be used as heating surface tube, economizer, superheater, reheater and petrochemical industrial tube of high-pressure boiler (the general working pressure is above 9.8 MPa, and the working temperature is between 450 ℃ and 650 ℃)
