The main production grade alloy tube specifications: 20MnG, 25MnG, 15CrMoG, 35crmo, 42crmo, 12Cr2MoG, 12Cr1MoVG, 12Cr2MoWVTiB, 10Cr9Mo1VNb, 10crmoal, 9cr5mo.9cr18mo, SA210A1, SA210C, SA213T11, SA213 T12, SA213 T22, SA213 T23, SA213 T91, SA213T92 , ST45.8 / Ⅲ, 15Mo3,13CrMo44,10CrMo910 etc. 1.1, hot P91 alloy pipe is generally automatic pipe mill production. Solid tube defects after inspection and clear surface seamless t91, t91 cut to the desired length of imported alloy pipe, end to end in the perforated tube centering surface, and then sent to the furnace heating Shanghai t91 alloy tube, perforated on the puncher. While continuing to rotate and move forward in the perforation, in the role of head of the roll and, gradually forming a cavity inside the tube, called capillary. Continue rolling and then sent to the automatic rolling machine. Finally, after all the whole entire thickness of both, the sizing mill sizing, to specifications. The use of continuous hot rolling pipe mill production P91 alloy tube is more advanced methods. I specialize in seamless steel, high alloy pipe, high pressure boiler tubes, low pressure boiler tubes, imported alloy pipe, oil cracking pipe, fertilizer tube, stainless steel casing pipe. While annual sales of several major steel production of seamless pipe, seamless pipe is larger suppliers. Company perennial with P91 steel pipe, T91 steel pipe, 10 #, 20 #, 35 #, 45 #, 20G, 40Cr, 20Gr, 16Mn, Q345B, Q345C, Q345D, 27SiMn, 1Cr5Mo, Cr5Mo, 12cr1movG, 10CrMo910,15CrMoG, 35CrMo, 40CrMo, T92, T23, T24, A335P92, A335P91, A335P22, A335P11 such as seamless steel pipe, sales outside diameter of 8-920, thickness 1-85mm20 #, 45 #, 16Mn seamless. Business: major steel production of seamless pipe, structural tubes, fluid tubes, low pressure boiler tubes, high pressure boiler pipe, fertilizer tube t91, oil casing, ship management, and a variety of domestic and imported alloy pipe materials Japan, the United States, Italy and other countries producing alloy tube.
