The single length of galvanized pipe is 6 meters. The length of galvanized seamless steel tube is uncertain. It depends on the length of seamless steel tube
Q:What's the difference between No. 20 steel pipe and 27SiMn Steel Pipe?
20# steel pipe material is 20 steel, generally 20 seamless steel pipe, 20# steel pipe material is: high quality carbon structural steel
Q:Material of welded steel pipe
GB/T14980-1994 (large diameter welded pipe for low pressure fluid delivery). Mainly used to transport water, sewage, gas, air, heating, steam and other low-pressure fluid and other uses. Its representative material is Q235 grade a steel.GB/T12770-1991 (stainless steel welded pipe for mechanical structure). Mainly used in machinery, automobiles, bicycles, furniture, hotels and restaurants, decorations and other mechanical parts and structures. Its representative material 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb and so on.
