What are the factors that affect the quality of alloy steel pipe?

The thickness uniformity and internal surface quality of gold capillary tubes affect the thickness and quality of alloy steel pipe products. Secondly, the temperature and uniformity during cold rolling of alloy steel pipes, especially the final rolling temperature, are related to the physical properties, diameter accuracy, and surface quality of products ordered under hot rolling conditions. Especially when the steel or pipe exceeds the temperature or even coarse-grained, it can lead to scrap. Therefore, in the processing of hot-rolled alloy steel pipes, heating and deformation temperature control must be strictly carried out in accordance with the processing requirements. The quality of processing process adjustment and the key quality of work affect the geometric appearance quality of alloy steel pipes. For example, the adjustment of cutting machines and rolling mills affects the thickness accuracy of alloy steel pipe products, while the adjustment of sizing machines is related to the diameter accuracy and straightness of alloy steel pipes. Moreover, the adjustment of processing technology also affects whether the entire cold rolling process can proceed normally. The quality and stability of special tools are directly related to the specification, accuracy, surface quality, and cost control of alloy steel pipes.
The cooling and lubrication of the processing technology, the cooling quality of the broken hole top edge, and the hot rolled strip steel not only affect their service life, but also affect the quality control of the inner and outer layers of alloy steel pipes. The cooling and lubrication quality of the core rod first affects the internal surface quality of the alloy tube, the accuracy of the alloy tube wall thickness, and the cost of the core rod; It also affects the load during cold rolling. The elimination and control of surface dirt on steel billets refers to the reasonable elimination of zinc dust on the inner and outer layers of alloy tube capillaries and waste tubes immediately before cold rolling deformation, and the control of reprocessing. For the solution of nitrogen and boron blowing on the internal threads of alloy steel pipes, high-pressure water descaling and equal diameter inlet can be reasonably improved and increased for the inner and outer layers
