Structural characteristics of steel jacket steel insulation pipe
Steel pipe piles are widely used in various situations such as support piles and friction piles. Especially when it is used as a support pile, since it can be fully driven into a relatively hard support layer, it can exert the bearing effect of the entire section strength of the steel material. E...Read more -
The comparison of production processes of lsaw pipe and dsaw pipe
Longitudinal Submerge-arc Welded pipes shortly for LSAW pipe is a kind of steel pipe whose welding seam is longitudinally parallel to the steel pipe, and the raw materials is steel plate, so the wall thickness of the LSAW pipes can be much heavier for example 50mm, while the outside diameter limi...Read more -
The comparison of safety between LSAW pipe and SSAW pipe
The residual stress of LSAW pipe is mainly caused by uneven cooling. Residual stress is the internal self phase equilibrium stress without external force. This residual stress exists in hot rolled sections of various sections. The larger the section size of general section steel, the greater the ...Read more -
The comparison of application scope between LSAW pipe and SSAW pipe
Steel pipe can be seen everywhere in our daily life. It is widely used in heating, water supplying, oil and gas transmission and other industrial fields. According to the pipe forming technology, steel pipes can be roughly divided into the following four categories: SMLS pipe, HFW pipe, LSAW pipe...Read more -
The advantages and disadvantages of spiral welded steel pipe
The advantages of spiral welded pipe: (1) The different diameters of spiral steel pipes can be produced by the same width coil, especially large-diameter steel pipes can be produced by narrow steel coil. (2) Under the same pressure condition, the stress of spiral welding seam is smaller than that...Read more -
Several common anti-corrosion processes of spiral steel pipe
Anti corrosion spiral steel pipe generally refers to usespecial technology for anti-corrosion treatment of ordinary spiral steel pipe, so that the spiral steel pipe has a certain anti-corrosion capacity. Usually, it is used for waterproof, antirust, acid-base resistance and oxidation resistance. ...Read more -
Action of chemical composition in steel
1. Carbon (C) .Carbon is the most important chemical element affecting the cold plastic deformation of steel. The higher the carbon content, the higher strength of steel, and the lower of cold plasticity. It has been proved that for every 0.1% increase in carbon content, the yield strength increa...Read more
