DIN 17175 Material Comparison Tables

DIN 17175 steel pipes are used in boiler installations, high-pressure pipelines and tank construction and special machinery for both high (градусов 600) temperature and high-pressure devices. This alloy steel pipe is just a big class,and it has many classifivations. We mainly produce DIN 17175 ST35.8,DIN 17175 ST45.8, and 10CrMo910 steel pipes.
Application:
used for the pipelines of boiler industry.

Tech & Service of Seamless pipe

Seamless pipes are extensively applied for the nuclear device, gas, petrochemical, ship building and boiler industries. seamless pipes dominates 65% of market share in Chinese boiler industry.

Seamless steel pipe eddy current testing and magnetic flux leakage testing comparison

With the development of the national economy, all kinds of seamless steel pipes are widely used in petrochemical, boiler manufacturing industry, especially the harsh working conditions such as high temperature, high pressure, seamless steel pipe quality higher requirements.
