Plastic-coated steel pipe is widely used in various urban projects because of its excellent performance. Under the background of the rapid development of China's construction industry, its market promotion and application also ushered in a development opportunity. Following is a brief introduction of some important characteristics of plastic-coated steel pipe, which is convenient for you to understand the plastic-coated steel pipe.
Characteristics and Construction Requirements of Plastic-coated Steel Pipe
Aging Resistance of Plastic-coated Steel Pipe
Plastic-coated steel pipe is anti-aging, especially suitable for buried water transportation. The new pipeline overcomes the shortcomings of easy rusting and scaling at the beginning of the plateau, and is also not prone to pipeline obstruction, which further increases its use time. Because of the heavy anticorrosive technology and the addition of flame retardant, its temperature-resistant effect is very good, both in the temperature of Sanyugong below zero and Baidu above zero. Can be used for a long time. Steel-plastic composite pipe is a new kind of pipe material developed in recent years in China. It is composed of steel pipe as the matrix and various plastics coated inside the pipe. The use of plastic materials has given this kind of pipe more excellent performance. It has not only the strength and stiffness of steel pipe, but also the advantages of chemical corrosion resistance, smooth inner wall and low fluid resistance of plastic pipe.
Construction Requirements of Plastic-coated Steel Pipe
Plastic-coated steel pipe fills in the blank of large-diameter plastic-coated steel pipe. Its excellent characteristics meet the requirements of the construction of pipe materials: 1. High strength, directly buried under the lane, no need to mix with doubtful soil protective layer. 2. The pipe is flexible and can resist the damage caused by external heavy pressure and foundation settlement. 3. Insulation, no electric corrosion, suitable for laying single-core cable; can be used in high temperature saline-alkali zone. 4. Flame retardant, good heat resistance, can be used at 130 degrees high temperature for a long time without deformation. 5. The inner wall is smooth and does not scratch the cable. Rubber seals are added at the joints to adapt to thermal expansion and cold contraction, which can prevent sand from entering. 6. The design adopts socket connection mode to facilitate installation and connection.
