China DIN 17175 Seamless Carbon Steel Boiler Tube Manufacturer at Wholesale Price

China Din17175 Boiler Tube Manufacturer and Supplier

DIN 17175 specifies the technical requirements for seamless heat-resistant steel pipes. Suitable for boilers, high-pressure pipelines and high-temperature equipment.

It covers a variety of heat-resistant steel grades (such as St 35.8, 15Mo3) and specifies chemical composition, mechanical properties, dimensional to-term high temperature (up to 600°C) stress.

This standard ensures pipes are reliable and safe under harsh conditions. It matches international standards, like EN 10216.
