Weak domestic demand, thick-walled seamless steel overcapacity weak Chinese demand, steel overcapacity, high cost pressure on companies to become the head of the "three big mountains" place, especially iron and steel enterprises, including, all tightly with the world closely linked economies. Take for example the production capacity, the production capacity of the rapid decline in 2008 after peak production process stainless steel seamless pipe, excellent quality, but throughout the world production point of view, there is still a surplus of 500 million tons 16Mn seamless steel pipe, overcapacity in the next few years seamless steel tubes, with the rise of China, India, Latin America, thick-walled seamless steel pipe production still will increase, at least in the world, the supply will still be oversupply. A structural seamless steel pipe (GB/T8162-2008) is used for seamless steel pipe for general structure and mechanical structure. 2 fluid seamless steel pipe (GB/T8163-2008) is generally seamless steel pipe used to transport water, oil, gas and other fluids. 3 low-pressure boiler seamless pipe (GB3087-1999) is used to manufacture various structural low and medium pressure boiler superheated steam pipes sanitary stainless steel tube, boiling water pipes and superheated steam locomotive boiler tubes, opium pipe, small smoke tubes and arch bricks of high quality carbon structural steel hot-rolled and cold drawn (rolled) seamless steel pipe. 4 high-pressure boiler seamless pipe (GB5310-1995) is used to manufacture high-quality carbon steel and more pressure water tube boiler heating surface with steel, alloy steel and heat-resistant stainless steel seamless pipe. 5 fertilizer equipment with high-pressure seamless steel pipe (GB6479-2000) is applied to the working temperature of -40 ~ 400 ℃, working pressure of high-quality carbon steel and alloy steel 10 ~ 30Ma of chemical equipment and seamless steel pipes. 6. Petroleum cracking (GB9948-88) is applied to the oil refinery furnace tubes, heat exchangers and pipe seamless steel pipe.
