In order to better protect electric wires, people nowadays use electric wires to lay pipes. The threading material used today is PVC. It refers to polyvinyl chloride resin as the main raw material, adding other additives through extrusion molding, used in industrial and construction engineering below 2000V wire and cable protection straight pipe. What are the advantages of PVC wire and pipe? What are the precautions for PVC wire and pipe construction? The following Xiao Bian made a sharing of these issues with everyone, looking forward to helping friends in need. What are the advantages of PVC wire and pipe? Compared with common wire tubes, PVC wire tubes have better cold bending performance, especially for big-brand products. The wire tube can be bent manually to a desired angle at room temperature without any other treatment. In addition, PVC wire and pipe have high compressive performance, and the heavy-duty PVC heavy-duty pipe has a maximum pressure of 1250N, so it can be concealed in the concrete and will not be damaged by pressure. What are the advantages of PVC wire and pipe? Hydropower is a hidden project. In order to ensure its safety, wire and pipe materials must have good flame-retardant insulation properties. The PVC pipe satisfies this requirement to the greatest extent. The coffin will self-extinguish within 30 seconds of leaving the flame; and the pipe can withstand AC2000V, 50Hz alternating current without breakdown, and the insulation resistance is more than 100MΩ. What are the advantages of PVC wire and pipe? Hydroelectricity is a hidden project. In many cases, electrical conduits are buried under the ground. Therefore, the wire tube should have good moisture resistance and corrosion resistance. PVC electrical conduits fully comply with this requirement. The joints of the pipes are adhesively bonded with PVC adhesive according to regulations, and can be waterproofed and infiltrated into the pipes. The moisture-proof effect is good, and it will not be rusted by various acid-base salts. PVC wire and pipe construction considerations In order to ensure the safety of hydropower construction, everyone has to pay more attention to construction. First of all, we need to pay attention to: the transportation, laying, installation and bending work of PVC threaded pipe and its accessories should be carried out at the permitted temperature specified by the material. All joints shall be sleeved with PVC adhesive to connect the corresponding fittings of the same specifications with the ends of the threading tube. When pre-embedded construction and wall piping are to be carried out on the first floor of the electrical piping structure, the electrical positioning must be marked on the wall one by one with a colored pencil according to the electrical layout of the apartment, and then the PVC threading pipe and the switch box must be installed. PVC wire and pipe construction considerations two After laying the wires, everyone should do a good job of troubleshooting. The requirements for construction are: the pipelines should be integrated, and there should be no defects such as the exposed wall of the pipe, the wall of the pipe, cracks, holes, or defects in the wall surface. Everybody should use the lead wire when sweeping. After the lead wire is passed through the pipeline, two insulated wires of appropriate cross-section and length should be taken. In addition, if there is a blockage in the PVC threading pipe in the sun terrace or toilet floor where waterproofing is required, it shall be handled in place prior to waterproof construction; if the pipe is modified and displaced after waterproof construction, the damaged waterproof layer must be re-constructed. Waterproof works and ensure that the test water passes. The above is the Xiaobian about the advantages of PVC wire and pipe and PVC wire pipe construction precautions related to sharing, to everyone to be a reference!
