Other critical pieces of equipment include extrusion machines, which force heated iron through a shaped die to create pipes of various diameters and wall thicknesses. This method allows for greater precision in dimensions compared to traditional methods. Additionally, advanced welding machines are employed to join pipe sections, ensuring strong and reliable seams that can withstand high pressure.
HF tube mills operate by feeding steel strips through a series of rollers that gradually shape the strips into a tubular form. The edges of the bent steel strip are then subjected to high-frequency electromagnetic fields, which induce currents in the material. This induction heating brings the edges of the steel to a high temperature, allowing them to be welded together without the need for additional materials or heat sources.
