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 -
Brief introduction of steel piling pipes
Structural characteristics of steel jacket steel insulation pipe 1. The rolling bracket fixed on the inner working steel pipe is used to rub against the inner wall of the outer casing, and the thermal insulation material moves along with the working steel pipe, so that there will be no mechanical...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 production process of spiral steel pipe
The spiral steel pipe is made by rolling low-carbon structural steel or low-alloy structural steel strip into pipe , according to a certain angle of spiral line (called forming angle), and then welding the pipe seams. It can be used for produce large diameter steel pipe with narrow strip steel. T...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 -
