Now the production of seamless steel pipe, mostly using hot-rolled technology, because the temperature is high, so the deformation resistance is relatively small, are generally used to complete the steel rolling process, in this operation, but also need to take into account the steel of the specific thickness, if it is relatively low for the accuracy requirements, it will not appear plate-shaped problem, mainly to control the main, that is, in terms of temperature control, but also a must take into account the problem , It can be said that this part of the consideration is also very important.

The market for seamless steel pipe has a clear quality requirements, especially for different alloy elements of the requirements can not be sloppy, where the harmful elements must be strictly controlled, but also need to take into account the pipeline material in the production after the completion of the risk And defects, such as cracks may occur, within the fold, outside the fold, rolling, from the layer, scarring, pull concave and so on, these must also be controlled within the scope of the agreement to avoid the quality problems.
