Carbon steel tube material and use
Carbon steel tubes are made of steel castings or solid round steel through holes to make capillaries, and then made by hot rolling, cold rolling or cold drawing. Carbon steel tubes have an important position in China’s seamless steel tube industry. The key materials are mainly q235, 20#, 35...Read more -
Seamless steel tube straightening process
1. The seamless steel tube enters the roller table at the entrance of the leveler from the upstream roller table. 2. When the head of the seamless steel tube is sensed by the sensor element in the middle of the entrance roller table, the roller table will decelerate. 3. When the head of the seaml...Read more -
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
