Hebei steel pipe industry Chiho tee pipe welding preheat before. Preheating is an important process carried pipeline welding, the purpose is to avoid preheated during welding SOUTH to high or low temperatures, or should become brittle and cracks of. During the welding operation, should be strictly in accordance with the specific requirements of the welding process to control the preheating temperature. After preheating, solder joints will reduce the cooling rate, cooling time is extended Forged steel tee, it is a good emission and diffusion of hydrogen to avoid hydrogen cracking. Easy to wear tee Chiho Pipe installation Hebei produced: the outer wall seamless series of specifications, which greatly facilitates the design and installation of the pipe, while good welding performance, weld, flanged connections. Fourth, high temperature resistance: high-chromium-nickel alloy lining can be applied at 600 ° C condition no distortion, no oxidation, and maintain a high abrasion resistance. Fifth, good corrosion resistance: in a certain temperature and concentration ability of various corrosive media (acids, bases, salts) and organic media (except for naphthalene solvent), 80 kinds of organic solvents in 20 ℃ and 80 ℃ were immersed Lag 30 days, without the appearance of any anomaly, other physical properties are almost unchanged. Sixth, good appearance, anti-fouling: This product outer wall seamless appearance of the product quality greatly improved, the installation can improve engineering standards, lined with centrifugal and vacuum casting, smooth wall, greatly improving the ability of anti-fouling pipeline . My company specializes in: GB tee, non-standard tee, tee-shaped steel tee, American Standard Three, German standard tee; various carbon steel straight seam seamless tee, straight tee joints , thick-walled tees. Also: Our design and production of all kinds of difficult tee pipe fittings, of the same diameter at any angle oblique tees, reducers oblique tees. Material: carbon steel tee, Q235 welded carbon steel tee, the 20th, A105,16Mn like. Welded carbon steel tee, Hebei Chiho (certified), Hakusan steel tee provided by Chiho Hebei Industry Co., Ltd.
