DN250 Water Supply Coated Composite Steel Pipe Manufacturing: DN250 Water Supply Coated Composite Steel Pipe is a new type of pipe material, and its manufacturing process needs to go through multiple steps. This article will introduce the manufacturing process and characteristics of DN250 water-coated composite steel pipe in detail. Plastic-coated steel pipes for water supply
First, the manufacturing process.
The manufacturing process of DN250 water-coated composite steel pipe mainly includes the following steps:
1.Tube selection and surface treatment.
First of all, choose the pipe that meets the requirements, such as seamless steel pipe, longitudinal steel pipe or spiral steel pipe. The inner and outer surfaces of the pipes are inspected to ensure that there are no defects. Pre-treatment of the pipe, including rust removal, degreasing, drying, etc., to improve the adhesion and corrosion resistance of the coating.
2.Preparation before painting.
Before coating, it is necessary to ensure that the surface temperature of the pipe is within the specified range and cannot be too high or too low. The surface of the pipe is re-inspected to ensure that there are no residues and impurities. According to the requirements of the coating, select the appropriate coating material and coating method.
3.Painting application.
Electrostatic spraying or other coating methods are used to evenly coat the surface of the tube. Control the thickness and uniformity of the coating to ensure that the coating quality meets the requirements. In the process of coating, the coating environment and temperature should be strictly controlled to avoid bubbles, cracks and other problems in the coating.
4.Curing and post-processing.
After the coating is completed, the pipe is cured to allow the coating to dry and cure fully at a certain temperature and time. After curing, the tube is post-processed, including inspection, trimming, packaging, etc., to ensure product quality and transportation safety.
Second, manufacturing characteristics.
The manufacturing characteristics of DN250 water-coated composite steel pipe mainly include the following aspects:
1.Excellent corrosion resistance.
DN250 water supply plastic coated composite steel pipe is made of high-quality coating material, which has good corrosion resistance, which can effectively prevent the pipeline from being eroded by various chemicals during use and prolong the service life of the pipeline.
2.Good environmental friendliness.
The coating materials are environmentally friendly products, which are non-toxic and harmless, and will not cause pollution to the environment. At the same time, the waste and wastewater generated in the manufacturing process have also been effectively treated and controlled, in line with environmental protection requirements.
3.Excellent hygienic properties.
The coating material has good hygienic properties, does not breed microorganisms such as bacteria and algae, and ensures the cleanliness and hygiene of the water in the pipeline. At the same time, the coating surface is smooth, not easy to accumulate scale, and is easy to clean and maintain.
4.Good thermal insulation performance.
The coating material has certain thermal insulation properties, which can effectively reduce the loss and waste of heat energy. In cold winters or hot water transportation, it can keep the water temperature stable and improve energy efficiency.
5.Easy to install.
DN250 water supply plastic-coated composite steel pipe adopts special connection methods, such as socket connection, clamp connection, etc., which is easy and quick to install. At the same time, the steel pipe is light in weight, easy to transport and install, which reduces the difficulty and cost of the project.
