PVC electrical conduit: the full name is "insulated electrical casing for construction". It is a rigid PVC hose with anti-corrosion, anti-leakage, flame-retardant and other functions. Because of its affordable price, good flexibility and good thermal insulation performance, it is also widely used in pre-buried buildings and home decoration.

1. PVC electrical pipes and wire pipes have strong pressure resistance, PVC threading pipe series can withstand strong pressure, can be laid open or hidden in concrete, and are not afraid of cracking under pressure.

2. Corrosion-resistant, insect-proof, PVC threading pipe series have acid and alkali resistance, and there is no plasticizer in the pipe, so there is no insect disaster.

3. The wire pipe has good flame retardancy. After the PVC threading pipe series is burned on the flame, it can stop itself quickly and prevent the fire from spreading.

4. The wire tube has strong insulation performance, can withstand high electricity without being broken down, and can effectively prevent leakage and electric shock accidents.

5. The construction of PVC electrical pipe and wire pipe is convenient, and the PVC threading pipe is light in weight-only 1/5 of the steel pipe is easy to bend. Insert a bending spring provided by us into the pipe, and it can be bent and formed manually at room temperature.

It is precisely because PVC wire pipes save investment, compared with steel pipes, the cost of materials and construction and installation costs can be greatly reduced during installation. Therefore, it has been recommended by more and more installers

PVC Electrical Conduit Installation Guide

1. Material acceptance

The quality of construction materials directly affects the construction quality and the hidden dangers caused by poor materials in future use. The inner and outer walls of the wire tube should be smooth and flat, free of bubbles, cracks, cracks, depressions, peeling and serious cold spots and obvious Mark of.

2. On-site disclosure

The installer should carefully read the drawings, confirm the location of the facilities and equipment, and know whether the owner or designer has any special requirements. If there are special requirements, the construction should be carried out according to the instructions of the owner or designer.

3. Pipe cutting

The pipe is cut by special pipe shearing. The bayonet of the pipe scissors should be adjusted to match the diameter of the pipe to be cut. When rotating and cutting, the force should be applied evenly. When the pipe is cut, the cross section should be perpendicular to the pipe axis. No glitches.

4. Pipe connection

The wire pipe is connected with the pipe fittings by hot melting. Before connecting, the dust and foreign objects on the pipes and accessories should be removed. When hot melting welding, do not rotate.

Precautions for the use of PVC wire and tube:

1. Should choose cost-effective PVC wire and tube

First observe the appearance of the wire tube. The inner and outer walls of the high-quality wire tube should be smooth, without obvious defects such as bubbles, cracks and uneven color; the inner and outer surfaces should have no convex edges and similar defects; The insulation layer of the cable; the wall thickness of the conduit should be uniform, at least 1.2mm or more. Generally speaking, the thinner the wall tube, the worse the mechanical properties, the better the combustion performance, and the tube wall is prone to brittleness, cracking and breaking.

2. Installation guide for PVC conduit related accessories

Manufacturers of PVC power pipes are generally equipped with direct fittings, elbows, tees and other accessories as standard. If the length is not enough during construction, they should be directly connected. Some workers often do not use elbows or straight heads in order to save trouble, and use manual bending or 2 The direct connection of each pipe will affect the pipe threading effect to a certain extent; the end of the pipe should go through the bottom box of the switch. Cut, the end here is the same as the middle, no wires are allowed to be exposed outside the pipe to prevent cement erosion, the pipe must be required to pass through the switch bottom box; when there is a bend, the standard angle can be connected with an elbow, or the wire pipe can be connected with a spring Bend to any angle.

Preservation Guide for PVC Conduit:

With the increasing use of PVC threading pipes, the number of manufacturers producing PVC threading pipes has gradually increased. Foreign importers should pay attention when storing PVC threading pipes to prevent PVC threading pipes from being damaged. When the PVC threading pipe is placed directly on the ground, the ground is required to be flat, there should be no stones and sharp objects that are likely to cause damage to the pipe wall, and measures must be taken to prevent the pipe from rolling. During the storage process of PVC threading pipe, the maximum storage deflection should not exceed 3% of the nominal diameter. The maximum operating temperature of the pipeline should be around 37°C. During the high temperature season in summer, sun exposure should be avoided, and the air circulation between the pipes should be maintained to prevent the temperature from rising. When stacking pipes with diameters of PVC threading pipes, the large and heavy ones should be put down, and the small and light ones should be placed on top. layer storage. During the storage process of PVC threading pipes, strict fire prevention measures are taken, and open flame construction such as electric welding and cutting near the pipes is prohibited.

In order to ensure that the PVC threading pipe can function normally, we must pay special attention when storing it to ensure that the PVC threading pipe is not damaged and that the PVC threading pipe works normally.
