Seamless steel tubes for boilers: These boiler tubes often work under high temperature and pressure, and the tube will also oxidize and corrode under the action of high temperature flue gas and water vapor. Therefore, the steel tube is required to have high durability and high oxidation resistance. And has good organizational stability.
