The under cold Spinning Head plant material, high-quality cold spinning the head plant http://www.hebftc8.com/ phone 0317-8210122, Phone 13722724665 cold Spinning Head plant material for chemical companies choose its operation harsh conditions, the material long-term exposure to high temperature, high pressure and critical hydrogen conditions, only a few steel mills abroad are able to produce steel for hydrogenation equipment. With China's increasingly high demand for oil quality, rapid growth hydrogenation plant construction, the hydrogenation steel increased sharply. In addition, the large scale of the scale of the device also makes a substantial increase in vessel wall thickness, all materials rely on imports, on the one hand, the long steel procurement cycle, increase product manufacturing cycle; On the other hand, the procurement costs increased dramatically, will restrict the development of the petrochemical industry .
