introduction
TP304 stainless steel steam pipe is made of austenitic stainless steel (UNS S30400, 304 stainless steel), suitable for medium and high temperature steam (≤650℃) transportation and distribution system. It is produced by welding (ERW/TIG), conforming to ASTM A312, ASME B31.1 and other standards, and is widely used in steam pipe networks, heat exchange equipment and sterilization systems in power, chemical, food, medicine and other industries.

Advantages of ASTM A312 TP304 high-frequency welded pipe
Effectively resist oxygen, water vapor and slightly corrosive media (such as sulfur-containing steam) in steam, avoiding oxidation peeling or pitting of pipelines.
TP304 seamless steam pipe is suitable for -20℃~650℃, meeting the temperature requirements of most industrial steam systems (such as saturated steam ≤300℃, superheated steam ≤500℃), maintaining good strength and creep resistance at high temperatures, and reducing the risk of pipeline deformation.
