The seamless steel tube is produced according to EN 10216-1 standard. It is provided with specified room temperature properties. The high pressure steel pipe is used to manufacture pipeline, vessel, equipment, pipe fitting and so forth. Due to special composition of its material, the industrial tube can be applied at normal working temperature, and is commonly seen in petroleum, gas and petrochemical industry.
