Stainless steel pipe is a hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, machinery and instrumentation and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also often used as furniture and kitchen utensils.
Stainless steel pipes are divided into seamless pipes and welded pipes according to the production method. Seamless steel pipes can be divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes and extruded pipes. Cold-drawn and cold-rolled are the secondary types of steel pipes. Processing; welded pipe is divided into straight seam welded pipe and spiral welded pipe.
Manufacturing method
According to different production methods, it can be divided into hot rolled tube, cold rolled tube, cold drawn tube, extrusion tube and so on.
1.1. Hot rolled stainless steel seamless tubes are generally produced on automatic tube rolling sets. The solid tube blank is checked and cleared of surface defects, cut into the required length, centering on the perforated end face of the tube blank, and then sent to the heating furnace for heating, and perforated on the punch machine. In the perforation at the same time continuous rotation and forward, under the action of the roll and the top, the tube blank gradually formed a cavity, called the wool tube. Then it is sent to the automatic pipe mill to continue rolling. Finally, the wall thickness of the whole machine is adjusted, and the sizing machine is adjusted to meet the specification requirements. It is an advanced method to produce hot rolled seamless steel tube with continuous rolling tube set.
1.2 If you want to obtain seamless tubes with smaller size and better quality, you must use cold rolling, cold drawing or a combination of both methods. Cold rolling is usually carried out on a two-high mill. The steel pipe is rolled in an annular pass consisting of a circular groove with a variable section and a stationary conical top. Cold drawing is usually carried out in 0.5 ~ 100T single chain or double chain cold drawing machine.
1.3. Extrusion method: The heated tube blank is placed in a closed extrusion cylinder, and the perforated rod moves together with the extrusion rod to extrude the extruded parts from the smaller die hole. This method can produce smaller diameter steel pipe.
