What is cpvc power tube? PVC-C resin is a masterbatch. The product has the characteristics of high strength, good flexibility, high temperature resistance, corrosion resistance, Flame Retardant, good insulation performance, no pollution, no aging, light weight, convenient construction and so on. National, provincial testing, identification and certification have reached or exceeded the level of similar products in China. So what is the connection method of cpvc power pipe? Let me introduce you to the following.
cpvc power tube
The main material of CPVC power pipe is PVC-C resin with excellent heat resistance and insulation performance. CPVC products are currently recognized as green and environmentally friendly products, and its excellent physical and chemical properties are being paid more and more attention by the industry.

Characteristics of cpvc power tube
1. Material characteristics: CPVC power pipes use PVC-C resin with excellent heat resistance and insulation properties as the main material. CPVC products are currently recognized as green and environmentally friendly products, and their excellent physical and chemical properties are getting more and more attention in the industry. The CPVC power pipe is a hard, straight and solid wall pipe. The inner and outer walls are smooth and flat, the color is orange-red, and the color is bright and eye-catching.
2. Heat resistance: CPVC power pipes have a heat resistance temperature increased by 15 ° C compared to ordinary UPVC double-wall corrugated pipes. They can remain undeformed in environments above 93 ° C and have sufficient strength.
3. Insulation performance: CPVC power pipes can withstand high voltages above 30,000 volts.
4. Compressive performance: The CPVC power pipe is modified by materials, and the ring stiffness of the product reaches 1Okpa, which is significantly higher than the regulations of the relevant state departments for buried plastic pipes whose ring stiffness should be above 8kpa.
5. High impact strength: CPVC power pipe can withstand 1kg weight and 2m height impact force at 0 ℃, fully reflecting the low temperature impact performance of the material is fully applicable to the requirements of the construction environment.
6. Flame retardant properties: Both PVC and PVC-C materials have good flame retardant properties and can be extinguished immediately after being fired. Especially PVC-C material, because its chlorine content is significantly higher than PVC, so the flame retardancy and smoke density index have been significantly improved.
7. Installation performance: CPVC power pipe is light in weight, high in strength, simple in construction and laying method, can be excavated and buried at night, backfill the road surface, and can be opened to traffic as usual during the day; using elastic sealing rubber ring socket connection, installation and connection The connection has good sealing performance, can prevent groundwater leakage, and effectively protect the safety of power cables.
8. Long service life: CPVC power pipe materials are resistant to corrosion, aging, and service life can reach more than 50 years.
CPVC power pipe connection method
1. Data preparation: Place the pipe or fitting in a straight position on the docking machine, leaving a 10-20mm cutting allowance.
2. Clamping: Select the appropriate slip clamp according to the welded pipe and fittings, clamp the pipe and prepare for cutting.
3. Cutting: cutting impurities and oxide layer on the welded pipe section and pipe end surface to ensure that the two butt end surfaces are smooth, smooth and free of impurities.
4. Alignment: The end faces of the two welded pipe sections should be completely aligned. The smaller the wrong edge, the better. The wrong edge should not exceed 10% of the wall thickness. Otherwise, it will affect the quality of the butt joint.
5. Heating: The jointing temperature is generally between 210-230 ℃, the heating time of the heating plate is different in winter and summer, and the melting length of the two end surfaces is preferably 1-2mm.
6. Switching: Remove the heating plate and quickly make the two hot melt end faces stick and pressurize. In order to ensure the quality of fusion butt, the shorter the switching period, the better.
7. Melt butt joint: It is the key point of welding. The process of butt joint should always be held under the melting pressure, and the crimping width should be 2-4mm.
8. Cooling: Keep the butt pressure unchanged, let the interface cool slowly, the cooling time depends on the curling of the hand, and you ca n’t feel the heat.
9. Realization of docking: After cooling, the slip is released, the docking machine is removed, and the next interface connection is prepared from the beginning.
10. The socket connection or interface connection is adopted for the connection of cpvc power sheath tube.
11. The surface of the cpvc power bushing should be marked with the insertion length. After the pipe is inserted into the socket, it is necessary to confirm whether the insertion mark is accurate and in place.
12. Before connecting the cpvc power jacket pipe, the soil or other attachments on the outside of the pipe socket and the inner surface of the rubber ring should be removed to facilitate the connection and prevent water leakage.
Editor's summary: Relevant information about the connection method of cpvc power pipe is introduced here for everyone, I hope this article will be helpful to everyone. If you still do n’t understand something, you can leave a comment below, we will answer it as soon as possible.
