Product Description

Seamless Carbon Steel Pipe DIN17175 used for Boiler and Pressure vessels


DIN 17175 standard applies to seamless steel pipes. These pipes can be used to manufacture steam boilers, pipes, pressure vessels and instruments operating at temperatures up to 600 ° C and at high temperatures. Due to the total load and special oxidation conditions, these pipes can be lowered or raised. High-listed temperature limits.
