Plastic-coated steel pipes combine the advantages of various pipe materials, offering safety, reliability, and environmental friendliness. They not only possess the strength of steel pipes but also benefit from the corrosion resistance, wear resistance, and low fluid resistance characteristic of plastic pipes. Next, let’s discuss the precautions for installing plastic-coated composite pipes.

Next, let’s talk about installation. Plastic-coated composite pipe Precautions?
Plastic-coated composite pipes boast superior overall performance and represent a new type of piping material in the modern pipeline industry—offering excellent cost-effectiveness, energy efficiency, and environmental friendliness. Plastic-coated composite pipes are set to see increasingly widespread applications in the future. They are suitable for both underground and humid natural environments and can withstand extreme high and low ambient temperatures. These pipes also exhibit strong resistance to electromagnetic interference. When plastic-coated steel pipes are used as cable protection conduits, they can effectively shield against external signal interference. The pressure-bearing formulation is highly robust, enabling these pipes to withstand gas pressures exceeding 6 MPa. Plastic-coated steel pipes possess excellent insulating properties, ensuring that no short circuits occur when used as cable protection conduits. Plastic-coated steel pipes should be free of burrs; their inner walls must be smooth and well-suited for wire threading during installation. When using plastic-coated composite pipes with large diameters, a sawing machine should be employed. During disc-type cutting, the rotational speed must not exceed 800 r/min. The cross-section of the cut pipe must be perpendicular to the pipe’s axis. After cutting, the pipe ends should be carefully deburred using a fine file. A specialized reamer should be used to chamfer the thickness of the plastic lining by 1/2, with a chamfer angle ranging from 10° to 15°. At the pipe ends, the plastic-coated composite pipes must remain intact and should be cut with a cutting tool to form an inclined internal chamfer. If the pipe end is damaged, it must be properly repaired.
Continue until the coating is free of cracks. After grooving, inspect and repair any damage to the plastic coating on the protruding parts of the groove until the coating surface becomes smooth and free of cracks and defects. When cleaning and processing coated composite pipes, use cotton swabs and brushes to remove oil, water, and metal chips from both the pipe ends and the inside of the pipe. Coated composite pipes—especially those with internal and external epoxy resin coatings—are highly competitive, whether used in potable water distribution systems or fire sprinkler systems, and whether applied in HVAC hot- and cold-water circuits or in underground coal mines where flammable and explosive conditions prevail. Thanks to their food-grade epoxy resin powder coating, these pipes fully meet the requirements of water supply systems as well as national standards for drinking water and related water quality. They offer excellent flame-retardant and fire-resistant properties; when burned at high temperatures, they do not produce dripping that could clog pipes. Complying with building fire safety and industrial safety regulations, these pipes are easy to install, which will further expand their application in fire protection systems.
