Application: Seamless steel tubes for low and medium pressure boiler (working pressure ≤ 2.5Mpa) and medium pressure boiler(working pressure ≤3.9 Mpa).Usage: Build superheated steam tubes, boiling water tubes, water cooled wall tubes, fire tubes and generating tubes etc. Generally, tubes are manufactured by high quality carbon steel of hot rolled or cold rolled tubes such as GB-10# and 20#.
Main Steel Grades
Kinds of dimension and steel grade, excellent mechanical properties. Thick wall tubes with WT/OD reaches 36% and thin wall tubes with WT/OD less than 4% can be produced. Mature piercing process, unique cold finishing technology, advanced lubrication process and reliable heat treatment technology ensure the stable products quality.
