A brief analysis of temperature and lubrication problems in the production process of straight seam steel pipes
In the process of producing straight seam steel pipes, the temperature must be strictly controlled, to ensure the reliability of welding. If the temperature is too low, it may cause the welding position to fail to reach the temperature required for welding. When most of the metal structure is sti...Read more -
About the production process and inspection standards of thick-walled straight seam steel pipes
Thick-walled straight seam steel pipe is a steel pipe made by rolling the long steel strip of the specification into a round pipe through a high-frequency welding unit and welding the straight seam. The shape of the steel pipe can be round, square or irregular, depending on the sizing and rolling...Read more -
Description of the length and mechanical properties of large-diameter steel pipes
The main processing methods of large-diameter steel pipes are: Forging steel: a pressure processing method that uses the reciprocating impact force of a forging hammer or the pressure of a press to change the blank into the shape and size we need. Extrusion: It is a processing method for steel to...Read more -
Internal anti-corrosion treatment method of large-diameter spiral steel pipes
The construction of cement mortar fabric should usually be carried out after the large-diameter spiral steel pipe is laid, the pressure test is qualified, and the soil is compacted according to the design requirements. Because the steel pipe has small rigidity and thin wall, the pipeline must be ...Read more -
