Can PVC pipes be used for weak current wiring in home decoration?

The standards currently implemented for PVC threading pipes (flame retardant threading pipes) include the Ministry of Public Security industry standard GA305-2001, the Ministry of Construction standard JG3050-2000, the local standard DB51/169-96, and some enterprise standards. If the standard implemented is the Ministry of Public Security standard threading pipe quality, the threading pipe that meets this standard is the most reliable, especially in terms of fire safety.

The full name of the threading tube is "insulated electrical conduit for construction". Generally speaking, it is a white hard PVC hose that is corrosion-resistant, leak-proof, and used for threading wires. It is divided into plastic threading tubes; stainless steel threading tubes; and carbon steel threading tubes.

It can be used in normal indoor environment and in places with high temperature, dust, vibration and fire hazard. It can also be used in humid places. It should not be used in places with extremely humid, acid, alkali, salt corrosion and explosion hazard.

It is used in normal indoor environment and in places with high temperature, dust, vibration and fire hazard. It can also be used in humid places. It should not be used in places with particularly humid, acid, alkali, salt corrosion and explosion hazard. The ambient temperature for use is -15℃～+40℃. The threading tube has excellent mechanical properties. Excellent corrosion resistance, the threading tube has high compressive strength and the working pressure exceeds 2.5Mpa. The threading tube has a smooth surface, low fluid resistance, no scaling, and is not suitable for the breeding of microorganisms. The thermal expansion coefficient is small and does not shrink and deform. Traditional installation and connection method. The epoxy coating layer of the threading tube more effectively solves the corrosion of water delivery, burial and acid, alkali and salt to metal pipes, and the service life can reach more than 50 years.

Different application fields require PVC pipes to have different functions, so the application of PVC conduit will also be different. The following editor will show you how to use PVC conduit in different places.

1. For conduits concealed in walls, buried in non-combustible materials, and used in ordinary residential buildings such as rural buildings, PVC conduits must be used that meet the Ministry of Construction standard JG3050-199[1] 8 "Insulating electrical conduits and accessories for buildings" and have certain flame retardant properties and meet the physical and mechanical property requirements. This should be done according to the specific conditions and local conditions.

2. For places with higher fire risk, such as hotels, restaurants, shopping malls (large supermarkets), libraries, singing and dancing entertainment venues and other public gathering places, when the lines in the ceiling and floor are protected by pipes, because there are more combustible and flammable materials in the ceiling and floor, flame-retardant PVC wire pipes with higher combustion performance levels should be used.

3. For fire-fighting power distribution lines and electrical lines of automatic fire alarm systems, it is mandatory to use flame-retardant PVC conduit that meets the standards of the Ministry of Public Security.

4. For the renovation of exposed electrical lines in cultural relics and ancient buildings, interior decoration and secondary decoration of houses, as well as the renovation of old buildings, exposed lines (hidden in the ceiling and floor) must be used, and flame-retardant PVC wire conduits with a combustion performance of B1 or above must be used.
