Schedule 40 Steel Pipe 4 Steel Pipe Hot-rolled seamless steel pipe delivery status is generally hot-rolled state after heat treatment for delivery. Hot-rolled seamless steel pipe after the quality inspection to go through the rigorous manual selection of workers, after the quality of the surface to be painted oil, and then followed by a number of cold drawing experiments, hot rolling after the perforation of the experiment , If the perforation is too large to be straightening correction. In the straightening and then sent by the transmission device to the flaw detector for testing, and finally labeled, the specifications arranged after the placement into the warehouse.

High-quality products
General seamless steel pipe production process can be divided into two kinds of cold drawing and hot-rolled, cold-drawn seamless steel pipe production process is generally more complex than the hot-rolled, the appearance of cold drawn seamless steel pipe is shorter than hot-rolled seamless steel pipe , Cold drawn seamless steel pipe wall thickness is generally smaller than the hot-rolled seamless steel pipe, but the surface looks thicker than seamless steel pipe, the surface is not too rough, caliber is not too much glitch.
