Our company was founded in 2000, which initially committed to providing high-quality steel A514 Gr Q QT steel plate products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export A514 Gr Q QT steel plate steel to the international market, opening up the international steel market.
The diameter of large diameter seamless steel pipe is 325mm-1220mm, and the maximum thickness that can be achieved is 200 mm. The diameter of small diameter seamless steel pipe is generally less than 89mm. The processing technology of large diameter seamless steel pipe is hot rolling or hot expanding. There are many materials for large diameter seamless steel pipe, such as A514 Gr Q QT steel plate, which can be processed and customized according to customer requirements. The large diameter seamless steel pipe is usually used in the chemical, petroleum, mechanical and other industries.
Now many manufacturers will use CNC equipment to complete the steel plate cutting processing, this processing method is also gradually increasing, but if you want to make the processing effect meet the specifications and standards, the control requirements of operation technology are also relatively high. Now there are many kinds of steel plate cutting, during the actual processing, it is necessary to select the appropriate processing method according to the cutting requirements of steel plate, so as to achieve the ideal processing effect for A514 Gr Q QT steel plate.
