Seamless Steel Pipe Extrusion Process Definition
Seamless steel pipe extrusion process is a manufacturing method to plastically deform the raw metal material by extrusion equipment, so as to obtain the seamless steel pipe with the desired cross-section shape and size.
How It Works?
Seamless steel pipe extrusion is the use of extruder to heat the metal billet to a certain temperature, and then in the mold to apply large pressure, so that the metal billet to produce plastic deformation, so as to form a certain shape and size of the tubular metal products. During the extrusion molding process, the billet in the die cavity produces a large amount of stress and deformation, which can eliminate defects in the metal billet and make the product structure more dense.
The Main Process Of Seamless Steel Pipe Extrusion Technology
1. Blank Heating
Before the extrusion molding of seamless steel pipe, the blank needs to be heated to a certain temperature. The heating temperature is generally above the recrystallization temperature of the metal, so that the metal blank can have good plasticity.
2. Pipe Extrusion
The heated blank is pushed into the extruder and extruded by the die to form a tubular metal product with a certain shape and size. The extrusion process requires high pressure to produce plastic deformation of the metal blank and continuously push the blank forward.
3. Cooling
After extrusion molding, tubes must be cooled to below room temperature. Cooling can be done with water or air.
4. Cut-To-Length
After cooling, the tubes need to be cut to length. The cuts must be accurate and not affect the tubes' properties.
5. Inspection And Warehousing
The cut steel pipe must be inspected for size and condition. Once approved, the pipe will be packed and stored until it is shipped.
