The main production processes of A106 steel pipe include hot rolling, cold rolling, cold drawing and extrusion.
A106 steel pipe, especially A106GrB seamless steel pipe, has various production processes. Hot rolling is one of the common production methods, usually carried out on an automatic pipe rolling unit, including the steps of heating the tube blank, perforating, rolling, uniform wall thickness and sizing to obtain steel pipes that meet the specifications.
In addition to hot rolling, if you need to obtain seamless pipes with smaller sizes and better quality, you can also use cold rolling, cold drawing, or a combination of the two. Cold rolling is usually performed on a two-roll mill, while cold drawing is performed on a single- or double-chain cold drawing machine. These methods can further improve the dimensional accuracy and surface quality of steel pipes.
In addition, the extrusion method is also a production process for A106 steel pipes. In this method, the heated tube blank is placed in a closed extrusion cylinder. Through the joint movement of the perforated rod and the extrusion rod, the extruded part is extruded from the smaller die hole, thereby producing a smaller diameter steel pipe.
The choice of these production processes depends on the specific steel pipe specifications, quality requirements and production conditions. A106 steel pipe is very popular due to its excellent performance and wide range of application fields, such as petroleum, chemical industry, boilers, power stations, etc.
