Plastic-coated steel pipe is a new type of steel pipe material, which has the characteristics of excellent corrosion resistance, environmental protection and non-toxicity, long service life, etc., and is widely used in water supply, drainage, fire protection, gas and other fields. Among them, the outer diameter of 1820*16 water supply plastic-coated spiral steel pipe is a relatively common specification, which will be introduced below. Plastic-coated spiral steel pipe for water feeding
1. Specifications and characteristics of plastic-coated spiral steel pipe with outer diameter of 1820*16 water supply.
The specifications of the outer diameter of 1820*16 water-coated plastic spiral steel pipe are: outer diameter of 1820 mm, and the thickness of the pipe wall is 16 mm. The steel pipe of this specification is made of high-quality steel and plastic coating process, and has the following characteristics:
1.Strong corrosion resistance: The surface of the plastic-coated steel pipe is coated with a layer of plastic film, which can effectively prevent the metal surface inside the steel pipe from contacting with the external corrosive medium, thereby improving the corrosion resistance of the steel pipe.
2.Environmentally friendly and non-toxic: The plastic film of plastic-coated steel pipe does not contain any harmful substances, and will not cause pollution and harm to the environment and human body.
3.Convenient construction: The connection method of the plastic-coated steel pipe is simple, and the clamp connection or threaded connection can be used, which is convenient and fast for construction.
4.Long service life: Due to the excellent corrosion resistance and environmental protection and non-toxic characteristics of plastic-coated steel pipes, its service life is longer than that of traditional steel pipes.
Second, the outer diameter of 1820 * 16 water supply plastic coated spiral steel pipe production process.
The production process of 1820*16 water-coated spiral steel pipe with outer diameter mainly includes the following steps:
1.Material selection: select high-quality steel as the base material, and require the steel surface to be smooth, no rust, no defects, etc.
2.Cutting: The selected steel is cut into the required length and diameter of the steel pipe.
3.Bending: The cut steel pipe is bent to form a spiral shape.
4.Welding: The bent steel pipes are butt welded together to form a complete steel pipe.
5.Grinding: Grinding the welded steel pipe to make the surface smooth and flat.
6.Plastic coating: Put the polished steel pipe into the plastic coating machine for plastic coating, and coat the surface with a layer of plastic film.
7.Testing: Inspect the plastic-coated steel pipe to ensure that it meets the requirements.
8.Packaging: The steel pipes that pass the inspection are packed to prevent damage during transportation and storage.
3. The application range of plastic-coated spiral steel pipe with outer diameter of 1820*16 water supply.
The outer diameter of 1820*16 water supply plastic-coated spiral steel pipe is widely used in water supply, drainage, fire protection, gas and other fields. In the field of water supply, it is widely used in the water supply system of tap water pipeline network and industrial water pipeline due to its excellent corrosion resistance and environmental protection and non-toxic characteristics. In the field of drainage, it is widely used in the pipes of sewage treatment plants and rainwater drainage systems due to its corrosion resistance and convenient construction. In the field of fire protection, it is widely used in fire pipe systems due to its high temperature resistance, pressure resistance, non-combustion and other characteristics. In the field of gas, it is widely used in gas pipeline systems due to its characteristics of pressure resistance and corrosion resistance.
In short, as a new type of steel pipe material, the outer diameter of 1820*16 water supply plastic-coated spiral steel pipe has the characteristics of excellent corrosion resistance, environmental protection and non-toxicity, and long service life, and is widely used in water supply, drainage, fire protection, gas and other fields. Its emergence provides a safer, more reliable and environmentally friendly pipeline solution for pipeline systems in various fields.
