Stainless Steel Pipes And Tubes Advantages And Disadvantages Of Steel Pipe

Stainless Steel Pipes And Tubes Advantages and disadvantages of steel pipe

Due to production needs, reduce production costs and production, many customers from the original cold drawn seamless steel pipe procurement of precision seamless steel pipe. The following is that we will gradually understand the advantages and disadvantages of precision seamless steel pipe:

Advantages: 1, precision seamless tube forming speed, high yield. , Without damaging the coating, can be made into a variety of cross-sectional models, applicable to the requirements of the conditions. 2, cold rolling process can make a huge lifting deformation of precision steel pipe, which improves the yield point of precision steel pipe. 3, the accuracy of precision steel pipe to reduce the waste of the user.

Disadvantages: 1, precision seamless pipe section residual stress exists, the overall and local buckling characteristics of precision seamless steel pipe effect; 2, precision steel pipe section free torsional stiffness is low; 3, cold-rolled precision seamless steel pipe wall thickness is small, Local centralized load capacity.

China Metallurgical News reporter from the China Metallurgical Construction Association, compared with the previous period (July 1 - December 31, 2012), the current (January 1, 2013 to June 30) to start a new project in China's steel production Reduced in recent years at a low level, but in 20 # precision steel pipe steel production capacity.

From a new start in the first half of this year, iron and steel production capacity, 11, the new project iron production capacity of 13.86 million tons, steel production capacity of 6.83 million tons on the 7th, six new ironmaking engineering design projects, production capacity of 280 10,000 tons, eight steel works, production capacity of 1.4 million tons; integrated iron and steel enterprises in the new project two or more process projects, the production capacity of 8 million tons; new production projects integrated steel enterprises 1 or more process Engineering, production capacity of 3 million tons, iron works 5, the production capacity of 6.92 million tons, 11 steel works, the production capacity of 1 million tons.

From the iron and steel production capacity of the various metallurgical projects: 35 in the ironworks project, the production capacity of 64.85 million tons; 27 steel engineering, production capacity of 24.42 million tons, 1 or more process engineering, integrated enterprise steel production capacity of 1.2 million tons. So, has started construction of iron ore production capacity of about 66 million tons, steel production capacity of about 26 million tons. Compared with the previous, the current productivity of about 12 million tons of iron, iron and steel production capacity of about 600 million tons. Eight steel engineering projects, production capacity of 4.1 million tons; 16 steel projects, production capacity of 7.76 million tons, two or more of the process of engineering, integration of the enterprise iron and steel production capacity of 6.3 million tons. In this way, the current design of the project iron production capacity of about 10.4 million tons, steel production capacity of about 14 million tons. Compared with the previous period, this period to reduce steel production capacity of about 700 million tons. Plan 1 ironmaking engineering, steel engineering 2, is the reform and reform projects, do not increase the capacity; 6 or more process projects, integrated enterprise steel production capacity of 34 million tons. In this way, the current planning project steel production capacity of about 34 million tons. If these projects under construction, design and planning have started to build project production capacity, will increase the iron production capacity of about 110 million tons of steel production capacity of about 74 million tons.

China Metallurgical Construction Association, the relevant person in charge, for metallurgical projects, the current statistics and the amount of investment, respectively, an increase of 99 and 83.43 billion yuan, an increase of 11.8%. Metallurgical industry as a whole, the scale of fixed asset investment at a low level. In addition, the statistical results also show that backward, energy-saving emission reduction, product structure adjustment and optimization of industrial layout of the project has gradually become the main content of the metallurgical construction market, reflecting the development of industrial engineering investment direction.
