The use and manufacture of fluid tubes
General boiler pipes are mainly used to make water wall tubes, boiling water pipes, superheated steam pipes, locomotive boilers with superheated steam pipes, large and small smoke pipe and arch brick.
High-pressure boiler pipes are mainly used to manufacture high-pressure and ultra-high pressure boiler superheater tube, reheater tube, air pipe, the main steam pipe.
However, the tube also has some limitations, such as in the plane under the conditions of bending, the tube is not as good as the square tube bending strength, some agricultural machinery skeleton, steel and wood furniture on the commonly used side, rectangular tube. According to different purposes also need to have other cross-shaped shaped steel pipe.
Seamless steel pipe for fluid delivery (GB / T8163-2008) is a general seamless steel pipe for conveying water, oil and gas.
Fluid tube manufacturing method
General use of the boiler pipes temperature below 450 ℃, domestic tube mainly with 10, 20 carbon steel hot-rolled tube or cold-drawn tube manufacturing.
High-pressure boiler pipes are often used in high temperature and high pressure conditions, the tube in the role of high temperature flue gas and water vapor, will be oxidized and corrosion. Requiring steel pipe with high durability, high oxidation resistance, and good organizational stability.
