High-pressure seamless steel pipe is a kind of seamless pipe. The manufacturing method is the same as seamless pipes, but there are strict requirements on the steel grades that used to produce steel pipes. According to the operating temperature, it can be divided into two types: ordinary boiler tubes and high-pressure boiler tubes.

①If the service temperature of high-pressure seamless steel pipes is below 450℃. Domestic pipes should be made of No. 10 and No. 20 carbon steel hot-rolled pipes or cold-drawn pipes.

②High-pressure seamless steel pipes are often used in high temperature. The pipes will be oxidized and corroded under the action of high-temperature flue gas and water vapor. The steel pipe is required to have high durable strength, high oxidation and corrosion resistance, and good organizational stability.
