1. Cutting of large-diameter plastic-coated steel pipes for water transportation. Metal saws should be used to cut steel pipes. Large-diameter steel pipes should be cut with saws. When cutting with entanglement, the rotation speed should not exceed 800r/min; the cross-section of the steel pipe to be

Hot-dip galvanized seamless pipes are generally coated with a layer of zinc on low-carbon steel, and the thickness of the zinc layer is generally 20um. The melting point of zinc is 419°C and the boiling point is about 908°C. During the welding process, zinc melts into a liquid.1. Use indirect fusion

1. Definition of straight seam steel pipe weldsStraight seam steel pipe weld refers to the joint part formed by joining two steel plates together through a welding process. The quality of the weld is directly related to the strength, sealing, and service life of the steel pipe.2. Welding process and

3PE anti-corrosion steel pipe base materials include seamless steel pipes, spiral steel pipes, and straight seam steel pipes. The three-layer polyethylene (3PE) anti-corrosion coating has been widely used in the oil pipeline industry due to its good corrosion resistance, water vapor permeability res

In construction projects, plastic-coated spiral steel pipes are an important pipe material and are widely used in various projects. Plastic-coated spiral steel pipe has the advantages of corrosion resistance, pressure resistance, wear resistance, etc. It has a wide range of applications and provides

Steel reducers are a type of reducing pipe fittings used at the reduced diameter of pipelines. Steel reducers are produced and manufactured by compression pressing, diameter expansion pressing, or reduction and expansion pressing. The steel reducer is The reducing forming process is to put the tube

The difference between seamless steel pipes and other long strips is that there are no seams around them, and the steel pipe section is hollow. Due to different cross-sectional shapes, they are often classified into round steel pipes and heterogeneous steel pipes. In terms of actual use efficiency,

Advances in materials processing have brought unique opportunities to the field of stainless steel pipe production. Typical applications include exhaust pipes, fuel lines, injectors, and other components. When producing stainless steel pipes, a flat steel strip is first formed and then shaped into a

Large-diameter seamless steel pipe is an important pipeline material and is widely used in petroleum, natural gas, chemical industry, electric power, aerospace and other fields. It has the characteristics of high strength, corrosion resistance, and good pressure resistance, and provides important su

The use of flanges in industrial structural parts is mainly to improve the connection function and keep the pipelines sealed and leak-free. However, many flanges will undergo corrosion and aging after being used for some time, thus losing the sealing effect. Therefore It is very necessary to conduct
