While high pressure boiler tube is mainly used for manufacturing superheater tube, reheater tube, gas pipe and main steam pipe of high pressure and ultra-high pressure boiler.
We supply all types of boiler pipes and heat-exchanger pipes, including seamless, heat-resistant steel pipes in accordance with DIN / EN and ASTM. Except seamless boiler tube ,we have stock carbon and alloy welded steel boiler tube，Please find more detailed information in our products catalog. welcome for inquiry.
Carbon seamless steel pipes is a kind of circular steel pipe with hollow section. Compared with solid steel such as round steel bar, Hot rolled seamless steel pipes has the same bending and torsional strength and light weight. It is an economic section steel. It is widely used to manufacture structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffold used in construction. Manufacturing ring parts with steel pipes can improve material utilization, simplify manufacturing processes, and save materials and processing hours, such as rolling bearing rings, Jack sleeves, etc. At present, steel pipes have been widely used for manufacturing.
