Application of seamless steel pipe for fluid transportation
② High pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, gas pipes and main steam pipes of high pressure and ultra-high pressure boilers.
However, the circular tube also has some limitations. For example, under the condition of plane bending, the bending strength of the circular tube is not as strong as that of the square or rectangular tube, and the square or rectangular tube is commonly used in some agricultural machinery skeletons, steel and wood furniture. Special shaped steel pipes with other cross-section shapes are needed according to different uses. Seamless steel pipe for fluid transportation is a general seamless steel pipe used to transport water, oil, gas and other fluids.
