Q345b High Pressure Boiler Tubes Steel Seamless Pipes Od 159mm Steel Pipe

 

Product Description: High-pressure boiler tubes are a type of boiler tubes and belong to the category of seamless steel tubes. The manufacturing method is the same as that of the seamless pipe, but there are strict requirements on the steel type used in the manufacture of the steel pipe. High-pressure boiler tubes are often under high temperature and high pressure conditions when used, and the tubes will be oxidized and corroded under the action of high-temperature flue gas and water vapor.
