Welded steel pipe refers to the steel pipe with a joint on the surface which is welded after the steel strip or steel plate is bent and deformed into circular, square and other expected shapes. According to different welding methods, it can be divided into arc welded pipe, high frequency or low frequency resistance welded pipe, gas welded pipe, furnace welded pipe, Bondi pipe, A514 grade J alloy steel plate, etc. According to the weld shape, it can be divided into straight welded pipe and spiral welded pipe. Electric welded steel pipes are mainly used in oil drilling and production, machinery manufacturing, etc.; furnace welded pipes can be used as water gas pipes, large-diameter straight seam welded pipes for high-pressure oil-gas transmission, etc.; spiral welded pipes are used for oil-gas transmission, pipe piles, piers, etc. Welded steel pipe has lower cost and higher production efficiency than seamless steel pipe.
The global share of my country's steel production has increased substantially. In the first nine months of 2020, my country's crude steel output accounted for 58% of the world's total, pig iron accounted for 69%, and imported iron ore accounted for 71% of global iron ore exports. "Such a high proportion is a manifestation of the effective control of the epidemic situation in our country and the strong demand. As the situation of epidemic prevention and control in various countries gradually improves, the proportion of my country's output will gradually decline." Luo Tiejun said.
