Sinopec Fourth Construction Co., Ltd. contracted and the quality of 2000 m3 propylene sphere welding tanks for auxiliary production facilities of Zhongyuan Petrochemical's ethylene raw material route reconstruction project was recently approved by the owners and supervisors. The propylene spherical tank is made of manganese nickel molybdenum vanadium cryogenic container material with a wall thickness of 48 mm and a metal weight of 350 tons. The company's project department in the process of welding the main body of the spherical tank in strict accordance with the first outside after the first, after the first longitudinal ring after the order, using the sub-districted step back symmetric welding method, the successful completion of the welding task.
The multifunctional hammer mill is widely used in crushing various biomass wood waste and straw material. The motor and the hammers are directly connected by the coupling. There is no dead angle during the crushing so the finished product is very fine. The corners of the hammers are welded with high hardness material like carbon tungsten alloy. The welding layer thickness is around 3mm. The lifetime is 7- 8 times by normal 65Mn overall quenching hammer. The rotor has made the balance test and can work backward. It`s the best choice to prepare milled material for pellet machine.
