As the basic processing materials and building materials, the medium and heavy plate is an important purchasing material for many manufacturers and construction enterprises, so the grasp of the latest price rise and fall of the medium and heavy plate, A514 Gr Q structural steel material is directly related to the cost and profit of enterprises. Therefore, it is necessary for purchasing staff to learn how to predict. Today, we share the latest price rise and fall skills, how to predict the price trend of medium and heavy plate, A514 Gr Q structural steel material.
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, A514 Gr Q structural steel material tube.
We have 4 typical production lines, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. SSAW pipe production line range is OD 219.1mm-3500mm, wall thickness 3.2mm-25.4mm. Product A514 Gr Q structural steel material annual capacity is 200 thousand tons.
