1.1. Hot- rolled seamless pipes are generally produced on automatic rolling mills. After inspection and removal of surface defects, the solid tube blank is cut into required lengths, centered on the end face of the perforated end of the tube blank, then sent to a heating furnace for heating, and perforated on a punching machine. During the continuous rotation and advancement of the perforation at the same time, under the action of the roll and the plug, a cavity is gradually formed inside the tube blank, which is called a capillary tube. And then sent to the automatic rolling mill to continue rolling. Finally, the wall thickness of the whole machine is averaged, and the diameter is sizing by a sizing machine to meet the specification requirements. It is a more advanced method to produce hot-rolled a106b seamless steel pipe with continuous rolling mill.
Seamless pipes are widely used. General-purpose seamless pipes are rolled from ordinary carbon structural steel , low-alloy structural steel or alloy structural steel, with the largest output, and are mainly used as pipelines or structural parts for conveying fluids.
According to different uses, it is divided into three categories: a, according to chemical composition and mechanical properties; b, according to mechanical properties; c, according to hydraulic test. Steel pipes supplied according to categories a and b, if they are used to withstand liquid pressure, shall also be subjected to a hydrostatic test.
There are many kinds of seamless pipes for special purposes, such as seamless pipes for boilers, seamless pipes for geological use and seamless pipes for petroleum.
The steel-plastic composite pipe is made of hot-dip galvanized steel pipe as the base, and the inner wall (the outer wall can also be used when needed) is coated with plastic by powder melting spraying technology, and has excellent performance. Compared with galvanized pipe, it has the advantages of anti-corrosion, no rust, no fouling, smooth and smooth, clean and non-toxic, and long service life. According to the test, the service life of the steel-plastic composite pipe is more than three times that of the galvanized pipe. Compared with plastic pipes, it has the advantages of high mechanical strength, good pressure resistance and heat resistance. Since the substrate is a steel tube, there is no embrittlement and aging problems. It can be widely used in fluid transportation and heating projects such as tap water, gas, chemical products, etc. It is an upgraded product of galvanized pipes. Because its installation and use method is basically the same as that of traditional galvanized pipes, and the pipe fittings are also the same, and it can replace aluminum-plastic composite pipes to play a role in large-diameter tap water transportation, it is very popular among users and has become the most competitive in the pipeline market. One of the new products.
The coated steel pipe is made of plastic coated on the basis of large-diameter spiral welded pipe and high-frequency welded pipe . The maximum diameter of the pipe mouth is 1200mm . Resin (EPOZY) and other plastic coatings with different properties, good adhesion, strong corrosion resistance, strong acid, strong alkali and other chemical corrosion resistance, non-toxic, non-rusting, wear-resistant, impact resistance, strong penetration resistance , The surface of the pipeline is smooth and does not adhere to any substances, which can reduce the resistance during transportation, improve the flow rate and transportation efficiency, and reduce the transportation pressure loss. There is no solvent in the coating and no exuding substances, so it will not pollute the conveyed medium, so as to ensure the purity and hygiene of the fluid. It does not crack, so it can be used in harsh environments such as cold regions.
A106B is also the Chinese material 20# corresponding to the American standard seamless steel pipe, the difference between the domestic American standard steel pipe and the imported American standard steel pipe.
