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, A709 Gr 36 bridge steel plate tube.
Ordinary carbon structural steel A709 Gr 36 bridge steel plate has many impurities and low price. The ordinary carbon structural steel is used in places with low performance requirements and low strength, but it has good plasticity, toughness and cold deformation performance. High quality carbon structural steel has less harmful impurities, and its strength, plasticity and toughness are better than those of ordinary carbon structural steel. High quality carbon structural steel is mainly used to manufacture important mechanical parts.
Due to the surge in business volume in recent years. In addition to coordinating our own truck fleet, our logistics department has continuously developed high-quality logistics companies and signed long-term cooperation agreements. While enjoying the professional and fast service of logistics companies, we have significantly reduced transportation costs. That not only ensure our customers receive the goods at the same time, but also help them reduce shipping costs.
Types of steel plates available: carbon structural steel plate, low-alloy high-strength steel plate, steel plate for bridge, steel plate for building structure, steel plate for shipbuilding and offshore platform, steel plate for boiler and pressure vessel, A709 Gr 36 bridge steel plate, steel plate for alloy structure, steel plate for oil and gas transmission pipeline, high-strength and high toughness steel plate, corrosion-resistant steel plate, clad steel plate, wear-resistant steel plate and more than 300 domestic and foreign steel grades.
