With the development of society, steel pipes are becoming more and more popular in our lives, and plastic-coated spiral steel pipes have received extensive attention and use. In this field, the outer diameter of 273*7 water supply plastic spiral steel pipe is even more attention-grabbing. Water Coated Steel Pipe First of all, let's take a look at the basic information of this kind of steel pipe. The outer diameter of 273*7 water supply plastic spiral steel pipe is a new type of pipe material, which is made of a layer of plastic powder coated on the surface of the steel pipe. This kind of steel pipe has excellent anti-corrosion performance and good hygienic performance, so it is widely used in the field of water supply. With an outer diameter of 273 mm and a wall thickness of 7 mm, this specification is sufficient to meet the needs of most water supply projects.
Secondly, let's take a look at the characteristics and advantages of the outer diameter 273*7 water-coated spiral steel pipe. This type of steel pipe has the following characteristics:
1.Excellent anti-corrosion performance: The surface of the plastic-coated spiral steel pipe is coated with a layer of plastic powder, which can effectively prevent oxidation and corrosion on the surface of the steel pipe, thereby prolonging the service life of the steel pipe.
2.Good hygienic performance: Due to the smooth surface of the plastic-coated spiral steel pipe, it is not easy to adhere to dirt and bacteria, thus ensuring the hygienic safety of drinking water.
3.Easy installation: The connection method of plastic-coated spiral steel pipe is simple and easy, which can greatly shorten the installation time and reduce the installation cost.
4.Good pressure resistance: Because the steel pipe itself has good strength and pressure resistance, coupled with the protection of the coating, the plastic-coated spiral steel pipe is more pressure-resistant and durable.
Next, let's take a look at the application range of water-coated spiral steel pipes with an outer diameter of 273*7. This kind of steel pipe is widely used in the following fields:
1.Water supply engineering: In water supply engineering, plastic-coated spiral steel pipes are widely used in the field of tap water and sewage treatment, which can ensure the sanitary safety of drinking water and the smooth discharge of sewage.
2.Construction: In the construction field, plastic-coated spiral steel pipes are widely used in building water supply, drainage and heating projects, which can effectively ensure the transmission of water and the durability of pipelines.
3.Petrochemical field: In the petrochemical field, plastic-coated spiral steel pipes are widely used in transporting high-temperature and high-pressure fluids such as petroleum and chemical media, with excellent pressure resistance and corrosion resistance.
4.Other fields: In addition to the above fields, plastic-coated spiral steel pipes are also widely used in electric power, communications, transportation and other fields, with a wide range of application prospects.
Finally, let's take a look at the production process of water-coated spiral steel pipe with an outer diameter of 273*7. The production process of this kind of steel pipe mainly includes the following steps:
1.Steel pipe surface treatment: First of all, the surface of the steel pipe needs to be cleaned and treated to remove impurities such as oil, rust and oxide scale on the surface to ensure the cleanliness and quality of the surface.
2.Coated plastic powder: After the surface treatment of the steel pipe is completed, the steel pipe needs to be coated with plastic powder, which is one of the most critical links in the whole production process. In the coating process, it is necessary to ensure that the plastic powder is fully bonded to the surface of the steel pipe, and at the same time, it is necessary to control the coating thickness and uniformity.
3.Heat treatment: After the coating is completed, the steel pipe needs to be heat-treated, so that the plastic powder is fully melted and solidified on the surface of the steel pipe to form a protective layer. This step is also one of the most critical steps in the entire production process, and it is necessary to control factors such as heating temperature and time.
4.Cooling treatment: After the heat treatment is completed, the steel pipe needs to be cooled so that the plastic powder is fully cooled and fixed on the surface of the steel pipe to form a stable protective layer.
5.Testing and acceptance: Finally, it is necessary to test and accept the plastic-coated spiral steel pipe produced to check whether its appearance, size, quality and performance meet the requirements to ensure the quality and safety of the product.
In a word, as a new type of pipeline material, the 273*7 water supply plastic-coated spiral steel pipe has the characteristics and advantages of excellent anti-corrosion performance, good health performance and pressure resistance, and is widely used in water supply engineering, construction, petrochemical industry and other fields. Its production process mainly includes steel pipe surface treatment, coating plastic powder, heat treatment, cooling treatment and testing and acceptance. In the future development, with the continuous progress of technology and the continuous growth of market demand, the application prospect of 273*7 outer diameter water-coated plastic spiral steel pipe will be broader.
