Material analysis of 3PE anti-corrosion steel pipe
3PE anti-corrosion steel pipe base material includes seamless steel pipe, spiral steel pipe and straight seam steel pipe. The three-layer polyethylene (3PE) anti-corrosion coating has been widely used in the oil pipeline industry due to its good corrosion resistance, water vapor permeability resi...Read more -
Advantages of hot-dip galvanized seamless steel tube
Hot-dip galvanized seamless tube is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pick...Read more -
Thermal expansion carbon steel pipe
What is heat-expanded steel pipe? Thermal expansion is a processing method of steel pipes, which is to process small-diameter steel pipes into large-diameter steel pipes. The mechanical properties of thermally expanded carbon steel pipe are slightly worse than that of hot rolled carbon steel pipe...Read more -
Structural seamless pipe
Structural seamless pipe (GB/T8162-2008) is a kind of seamless steel pipe used for general structure and mechanical structure. The fluid seamless steel pipe standard applies to seamless steel pipes that transport fluids. In addition to carbon (C) elements and a certain amount of silicon (Si) (gen...Read more -
How to avoid bubbles in welded carbon steel pipes?
It is common for welded carbon steel pipes to have air bubbles in the weld, especially large-diameter carbon seamless steel pipe weld pores not only affect the tightness of the pipeline weld and cause pipeline leakage, but also become the induction point of corrosion, which seriously reduces the ...Read more -
8 Precautions for seamless pipe forming
Forming and sizing of seamless pipes, some hole design and adjustment methods will directly affect the quality, so we should pay attention to the following eight points when handling the forming of seamless pipes: 1. Before there is no perforation, the hole shape of each rack should be adj...Read more
