Hebei Chiho seamless tube industry is generally standard tee, diameter and have Ⅰ series Ⅱ series, if the nominal size DN150x100, an outer diameter of Ⅰ series, thickness grade Sch20, made of 20 concentric reducer fittings # marked as DN150X100 Ⅰ-Sch20-20 R (C) GB / T12459. Butt tee by GB / T12459 identification, such as DN100X100X80. Seamless tee oil, chemical pipeline project is an important and a larger amount of pipe fittings, currently 316 stainless steel tee, in the most part of the pipeline project tee casting, forging tee, tee welding tee tube and squeeze tee. Quality assurance is not easy due to the seamless stainless steel tee tee, during the installation process often requires a lot of welding work stainless steel links, which directly affect the progress of the project, and the defect is not easy to check seamless tee, often leak occurs after the project begins accident, so should not be used in the oil, chemical pipeline. Seamless tee larger size, in the processing of a lot of material to be cut, steel consumption and the process is more complicated, high processing costs. Hebei Chiho carbon steel pipe industry: brands such as Q235-A · F, represents σs = 235MPa. Note (Q represents the yield strength, A represents quality level (there are four ABCD), F represents boiling steel). Used in general engineering construction and general mechanical parts, such as can be made bolt, nut, pins, hooks and less important mechanical parts and steel building structure, steel, steel and so on. Quality carbon structural steel: grade as in Example 45,65Mn, 08F (direct representation of the amount of square metal carbon fraction), an important non-alloy steel used in the manufacture of mechanical parts, are generally required to heat treatment after use. 08F of low carbon content, plastic, low intensity seamless stainless steel links for stamping parts such as automotive and instrumentation shell; Cast: Grade example ZG200-400, expressed σs = 200MPa, b = 400MPa of steel. Its performance is worse than having a cast iron, but the mechanical properties better than cast iron. Mainly used in the manufacture of complex shape, the mechanical performance requirements, but in the process the more important and difficult to use mechanical parts, such as forging forming method, such as the transmission housing of the car, rolling stock coupler and couplings. 316 stainless steel tee, stainless steel tee Laiwu, Hebei Chiho (view) provided by Chiho Hebei Industry Co., Ltd.
