The working principle of carbon steel pipe mainly includes its manufacturing process and application areas. Carbon steel pipe is made by perforating, hot rolling, cold rolling or cold drawing of steel ingots or solid round steel. The specific manufacturing process is as follows:
Raw material preparation: The raw material of carbon steel pipe is round tube billet, which is cut into segments of about 1 meter long and then sent to the furnace to be heated to about 1200 degrees Celsius.
Piercing: The heated round tube billet is perforated by a pressure perforator. The common perforator is a tapered roller perforator, which has high production efficiency and good product quality.
Rolling: The perforated round tube billet is formed into a steel pipe by three-roller oblique rolling, continuous rolling or extrusion. This process will make the diameter and wall thickness of the steel pipe reach the required size.
Sizing and cooling: The sizing machine uses a tapered drill to rotate at high speed into the steel billet to punch holes to form the inner diameter of the steel pipe. After the steel pipe is cooled by water spraying in the cooling tower, it is straightened.
Quality Inspection: After straightening, the steel pipes are inspected internally by metal flaw detectors or water pressure tests to ensure that there are no cracks or bubbles.
Finally, the steel pipes are hand-selected, sprayed with numbers, specifications and production batch numbers, and stored in the warehouse.
