Hot rolled pipe A106B seamless steel pipe

〣Description

Hot rolled seamless pipes are usually produced on automatic tube rolling units. The solid tube billet is inspected and cleared of surface defects, cut into the required length, centered on the perforated end face of the tube billet, and then sent to the heating furnace for heating, and perforated on the perforating machine. In the perforation at the same time constantly rotating and advancing, under the action of the roll and the head, the blank tube gradually formed inside the cavity, called the capillary tube. It is then sent to the automatic pipe mill for further rolling. Finally, the wall thickness of the whole machine is adjusted, and the sizing machine is calibrated to meet the specification requirements. It is an advanced method to produce a106b seamless steel pipe with continuous tube rolling unit.

〣Use

Seamless pipes are very versatile. The general purpose seamless pipe is rolled by ordinary carbon structural steel, low alloy structural steel or alloy structural steel, and has the largest output. It is mainly used as pipe or structural parts for conveying fluids.

〣Classification

(a) Supply by chemical composition and mechanical properties; b. Supply according to mechanical properties; c. Supply according to hydraulic test. Steel tubes supplied according to class a and Class b, if used to withstand liquid pressure, shall also be subjected to hydrostatic tests.

Special purpose seamless pipe with boiler seamless pipe, geological seamless pipe and seamless pipe with oil and so on.

〣Performance

Steel-plastic composite pipe is made of hot-dip galvanized steel pipe as matrix, and coated with plastic on the inner wall (or outer wall when necessary) by powder melting spraying technology, with excellent performance. Compared with galvanized pipe, it has the advantages of corrosion resistance, no rust, no scaling, smooth and smooth, clean and non-toxic, long service life, etc. According to the test, the service life of steel-plastic composite pipe is more than three times that of galvanized pipe. Compared with plastic pipe, it has the advantages of high mechanical strength, good pressure resistance and heat resistance. As the matrix is steel pipe, there is no embrittlement, aging problems. Can be widely used in tap water, gas, chemical products and other fluid transportation and heating projects, is galvanized pipe upgrading products. Because its installation and use method is basically the same as the traditional galvanized pipe, the form of pipe fittings is also exactly the same, and can replace the aluminum plastic composite pipe in large diameter tap water transmission to play a role, welcomed by users, has become one of the most competitive new products in the pipeline market.

Coated steel pipe is coated with plastic on the basis of large diameter spiral welded pipe and high frequency welded pipe. The maximum diameter of pipe mouth is 1200mm. It can be coated with PVC, PE, EPOZY and other plastic coatings with different properties according to different needs. Non-toxic, no corrosion, wear resistance, impact resistance, strong permeability resistance, smooth surface of the pipeline, does not adhere to any substance, can reduce the resistance of transportation, improve the flow rate and transportation efficiency, reduce the transportation pressure loss. There is no solvent in the coating, no oozing substance, so it will not pollute the conveying medium, so as to ensure the purity and hygiene of the fluid, in the range of -40℃ to +80℃ can be used alternately hot and cold cycle, not aging, not cracking, so it can be used in harsh environment such as cold zone.

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.
