  Welded steel pipe blank steel sheet or strip, and which are welded steel pipe

Welded pipe commonly used material: Q235A, in fact q235 material steel pipe specifications table. Q235B, 16Mn, 20 #, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb. Welded steel pipe blank steel sheet or strip steel, hot rolled thick welded pipe Yan Sen. Its different welding process is divided into the furnace pipe welding (resistance welding) pipe and active arc welded pipe. Want to know the blank. Its the welding form of different divided into two kinds of Longitudinal and spiral welded pipe. Circular welded pipe and shaped (square, flat) pipe is divided into its end look. Hot rolled thick-walled welded pipe Yan Sen. Welded pipe is divided into following certain types: GB/T3091-2001 (high pressure fluid transportation with galvanized welded steel pipe) because of its material and useful. Critical for the conveyance of water, gas, environment, oil and heating hot water or steam ordinary high pressure fluid and other useful tube. Want to know Hebei thick-walled welded pipe. The representative of material: Q235A grade steel.
Seamless steel tube quenching tank water quenching and slot external water quenching. Tank water quenching process is the most simple way is to dip quenching; easy to make inconsistent steel top and bottom of the cooling rate, pipe bending. Slot external water quenching process more successful "rotation, while the steel pipe, steel pipe inner surface of the axial water spray, the outer surface of the laminar flow of water quenching water quenching heat treatment process. Immersion quenching immersion quenching plus inner axial injection outside injection plus inner axial injection layer stream injection plus inner axial injection cooling capacity of the cooling method, the steel pipe outer surface layer stream injection and the cooling capacity of the inner axial injection process strong, high efficiency of quenching. Together with steel pipe rotating device, allows uniform cooling and cooling minimal deformation pipe in the circumferential direction. Steel pipe internal and external surface of the cooling in the form of different, often cause steel pipe cooling uneven, resulting in deformation. Direction along the length of pipe within the axial injection uneven cooling can give to make up for by the local water volume adjustment layer. In actual production, large diameter steel pipe (DN ≥ 300) need to be quenched, within the axial jet full of inner hole is not only a waste of water resources, and will increase the cooling, pumping stations and other investment.
