Cold rolling refers to the processing of steel plates or strips into various types of steel through cold working such as cold drawing, cold bending, and cold drawing at room temperature. Carbon steel pipes are divided into two categories: hot-rolled and cold-rolled (drawn) steel pipes. Carbon steel pipes are made of steel ingots or solid billets through perforation into…
Read MoreThe production method of seamless steel pipe is roughly divided into the cross-rolling method and the extrusion method. The former method is to pierce the tube with oblique rolls and then stretch it with a rolling mill. This method has a fast production speed, but has higher requirements on the processing performance of the tube blank, and is mainly…
Read MoreWhat are the factors that affect the quality of American Standard seamless tubes? 1. Temperature Temperature is the main factor affecting the quality of American Standard seamless steel tubes. First of all, the uniformity of the heating temperature of the tube blank directly affects the wall thickness uniformity and inner surface quality of the perforated capillary, which in turn…
Read MoreWhat is carbon steel pipe? Carbon steel pipe is also called CS pipe. Carbon steel pipes are made of steel ingots or solid round steels through perforation into capillary tubes, which are then hot-rolled, cold-rolled or cold-drawn. Carbon steel pipe plays an important role in my country’s steel pipe industry. Types of carbon steel pipes: Carbon steel pipes are…
Read MoreThe oxide film on the surface of the hot-rolled seamless pipe is thin and high in density, and it is not easy to fall off. Under normal circumstances, the hot-rolled seamless pipe will cause 0.2-0.3mm oxide scale in the heat treatment equipment, and the casting defects in this range will be It can be removed with the oxidation of…
