With the wide application of pipeline engineering in urban construction, the requirements for water supply pipes are getting higher and higher. As a new type of pipe, DN300 water supply plastic-coated composite steel pipe has been widely used in the field of water supply because of its excellent performance and environmental protection. In this paper, the production process and quality control of DN300 water-coated composite steel pipe will be elaborated in detail. Plastic-coated steel pipes for water supply
First, the production process.
1.Raw material preparation: high-quality steel is selected as the base material to ensure that its surface is smooth, no rust and no oil stains. The coating material needs to meet the relevant standards to ensure its adhesion, anti-corrosion performance and environmental performance.
2.Pretreatment: The substrate is treated with rust and oil removal to ensure that its surface is clean to improve the adhesion and anti-corrosion performance of the coating.
3.Coating process: advanced coating equipment is used to evenly coat the coating material on the surface of the substrate. During the coating process, the temperature, humidity and coating time need to be controlled to ensure that the thickness and uniformity of the coating meet the requirements.
4.Curing treatment: After the coating is finished, it needs to be cured at high temperature to make the coating tightly bound to the substrate. The curing temperature and time need to be strictly controlled to ensure the quality of the coating.
5.Testing and packaging: Perform various performance tests on the finished tube to ensure that it meets the requirements of relevant standards. Qualified products are packaged for easy transportation and storage.
Second, quality control.
1.Quality control of raw materials: strictly control the quality of raw materials, select high-quality steel and environmentally friendly coating materials, and ensure product quality from the source.
2.Production process control: formulate strict process operation procedures to ensure that the process parameters in the production process are effectively controlled. Strict monitoring of key process links to prevent quality fluctuations in the production process.
3.Quality inspection and inspection: Establish a sound quality inspection and inspection system, and carry out strict quality inspection on the finished pipe. Including appearance, size, coating thickness, adhesion and other items to ensure that the product quality meets the standard requirements.
4.Personnel training and assessment: Regularly train and assess production personnel to improve their skill level and sense of responsibility. Through training and assessment, ensure that production personnel can be proficient in process operation procedures and improve product quality stability.
5.Quality traceability and continuous improvement: Establish a sound quality traceability system to monitor the whole process of product production. Trace and deal with quality problems in a timely manner to prevent them from expanding. At the same time, by collecting user feedback and market information, we will continue to improve product performance and production process to improve product quality and market competitiveness.
As a new type of pipe, DN300 water supply coated plastic composite steel pipe has excellent performance and environmental protection. Through strict control of production process and quality control, the quality of its products can be guaranteed to be stable and reliable. With the continuous progress of technology and the continuous growth of market demand, it is believed that DN300 water supply plastic-coated composite steel pipe will play a more important role in water supply projects in the future.
