SEAMLESS PIPE

SEAMLESS PIPE

What is a seamless tube? It is a type of boiler tube and belongs to the category of seamless steel tubes. The manufacturing method is the same as that of seamless steel pipes, but there are certain strict requirements on the steel grades used in the manufacture of steel pipes. Since seamless pipes are often in high temperature and high pressure conditions when they are used, seamless pipes are mainly used to make superheater tubes, reheater tubes, steam guide tubes, and main steam seamless tubes for high pressure and ultra-high pressure boilers.

The production method of seamless pipes can be divided into general boiler pipes and high-pressure boiler pipes according to the use temperature. When seamless pipes are used, they are often exposed to high temperature and high pressure. The pipe will be oxidized and corroded under the action of high temperature flue gas and water vapor. The steel pipe is required to have high durability, high resistance to oxidation and corrosion, and good structural stability.
