At present, hot rolling technology is mostly used in seamless pipe production. Because of the high temperature, the deformation resistance is relatively small. Generally, the steel plate is used to complete the rectification and rolling process. In this process, the specific thickness of the steel plate should also be taken into account. If the precision requirement is relatively low, the shape of the steel plate will not appear. In other words, in the aspect of temperature control, it is also a problem that must be taken into account. It can be said that the consideration of this part is also very important for quality of seamless pipe.
There are distinct quality requirements for seamless pipe in the market, especially for different alloy elements. The harmful elements in seamless pipe must be strictly controlled. The hazards and defects of pipeline materials after production, such as cracks, internal folds and external folds, should also be taken into account. The problems of rolling, delamination, scarring, drawing and concave must also be controlled within the agreed scope to avoid quality problems of seamless pipe.
