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, at present, most of the pipeline project with cast tee, Forged tees, tee welding tee and squeeze tee. Quality assurance is not easy because the seamless tee, during the installation process often requires a lot of welding work and thus directly affect the progress of the project, and the defect is not easy to check seamless tee, often spill occurred after the project put into operation, it should not in oil CHEMICAL pipe use. Seamless tee larger size, in the processing of a lot of material to be cut, steel consumption and the process is more complicated 16mn carbon steel tee, high processing costs. Hebei steel pipe industry Chiho tee factors influence coverage of parts and materials hardness, projectile diameter, spray angle and distance, shot peening time. When peening intensity at the specified conditions, the hardness of the parts is less than or equal to the standard test piece hardness steel tee, coverage can reach 100%; the other hand, the coverage will decline. In the same projectile flow, the longer the distance between the nozzle and the workpiece, the smaller the angle of ejection, the smaller the diameter of the projectile to reach the shorter the time required coverage. Carbon steel tee manufacturer should choose the right size projectiles when shot peening, spray angle and distance so that shot peening intensity and coverage while achieving the required value. Due to the surface roughness of steel shot injection, the surface roughness of the workpiece of carbon steel tee produce some changes. Factors affecting the surface roughness has the strength and hardness, projectile diameter of parts and materials, the original surface angle and speed of injection, parts of roughness. Under the same other conditions, part material strength and surface hardness higher the value, the more difficult the plastic deformation, the more shallow crater, the smaller the surface roughness; the smaller the diameter of the projectile, the slower the speed, the more shallow crater, surface roughness becomes small; injection angle, the projectile velocity normal component is smaller, the smaller the impact, the more shallow crater, the larger the cut the projectile velocity projectile abrasive surface of the greater surface roughness smaller; the original surface roughness of the parts is one of the factors, the rougher the surface of the original steel tee, reducing the surface roughness after blasting smaller; on the contrary, the smoother the surface, the surface becomes after blasting too rough. When the parts are high-intensity blast, the deep crater, not only to increase the surface roughness, but also form a large stress concentration, severely weakened the effect of shot peening blast tee carbon steel tee manufacturer, Qingdao carbon steel tee, Hebei Chiho (view) provided by Chiho Hebei Industry Co., Ltd. .
