Product Description

DIN17175 St35.8 Carbon Steel Seamless Boiler TIube 
 

DIN17175 St35.8 St45 Heat seamless steel pipe is used for the high-pressure boiler (working pressure generally above 9.8 Mpa, working temperature between 450 ºC ~ 650 ºC) of the heating surface pipe, economizer, superheater, reheater tube, petrochemical industry, etc.

DIN 17175 steel pipes are used in boiler installations, high-pressure pipelines and tank construction, and special machinery for both high temperature and high-pressure devices.

Surface treatment: Oil-dip, Varnish, Passivation, Phosphating, Shot Blasting.
