The material of PVC pipe is called polyvinyl chloride. It is a thermoplastic resin material. It has very good mechanical properties and tensile strength of about 60 MPa. Adding some auxiliary agents in the process of pipe making PVC pipe is flame retardant and resistant. Acid and alkali, wear-resistant properties, and the most important insulation for the threading pipe. These excellent characteristics make PVC threading pipe occupy a huge market.
Different application fields require PVC pipes to have different functions, so PVC threading pipes will be different in application. The following small series will take you to see how to use PVC threading pipes in different places.
1. For the line pipe that is darkly applied to the wall, buried in the underground and not burned in the body, and the line pipe for ordinary residential houses such as rural buildings, it must be used to meet the requirements of the Ministry of Construction JG3050-1998 "Insulated electrical bushings and accessories for construction" 》The PVC threading tube has certain flame retardant properties and meets the requirements of physical and mechanical properties. According to the fine and local.
2. For places with high fire risk, such as hotels, restaurants, shopping malls (large supermarkets), libraries, song and dance entertainment venues, and other public gathering places, the ceilings and the lines inside the floor are protected by pipes, because of the ceiling inside the floor. If there are more flammable and flammable materials, flame retardant PVC threading pipes with higher combustion performance level should be selected.
3. For the fire-fighting distribution line and the automatic circuit of the fire alarm system, it is mandatory to use the flame-retardant PVC threading pipe that meets the requirements of the Ministry of Public Security.
4. For the renovation of cultural relics, the construction of electric wiring, the decoration of interior decoration and the secondary decoration of the house, and the transformation of old and old buildings, it is necessary to use the Mingchuang line (hidden in the ceiling and the floor), and the combustion performance must be above B1. Flame retardant PVC threading pipe.
