The production method of seamless steel pipe can be roughly divided into cross rolling method (menesmann method) and extrusion method. The cross rolling method (menesmann method) is to pierce the tube blank with the cross roll first, and then extend it with the rolling mill. This method is fast in production, but requires high machinability of tube blank. It is mainly suitable for producing carbon steel and low alloy steel tube, AH32 marine grade steel plate tube.
The steel used for offshore platforms in various countries in the world is divided into mild steel, medium-high-strength steel and high-strength steel. At the same time, considering the stability and reliability of offshore platform components, steels of different strengths need to meet different yield ratios. In addition, due to the different parts used on the offshore platform, the thickness requirements of the steel plate are also different.
Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
