Most of the
seamless steel tubes produced now use hot rolling technology. Because of the high temperature, the deformation resistance is relatively small. Generally, the steel plate is used to complete the rectification rolling process. In this operation, it is also necessary to consider the The specific thickness, if the accuracy requirements are relatively low, the shape problem will not occur, mainly control-oriented, that is, in terms of temperature control, it is also a problem that must be considered at the same time, It can be said that the consideration of this part is also very important.
There are clear quality requirements for seamless pipes in the market, especially for different alloy elements. The harmful elements must be strictly controlled, and the danger of pipeline materials after production is also considered. And defects, such as cracks, internal folds, external folds, rolling, delamination, scarring, dents, etc., these must also be controlled within the agreed range to avoid quality problems.
