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.
