The PVC transparent wire tube is the main material of the polyvinyl chloride resin and the main material of the polyvinyl chloride resin. But the additives are different in the production process. These additives are not visible, but their differences directly affect the flame retardancy and bending properties of PVC pipes. In addition, the quality of the resin directly affects the price and quality of the PVC production line. The most important thing about PVC pipes is their pressure resistance.
If the compression performance is poor, cracks and cracks may occur under a certain strength and pressure. Therefore, when purchasing PVC pipes, we should pay attention to the applicability of PVC pipes at the price. Rugged and resistant to breakage. The PVC pipe can be tested in the field. Foot pedals or hollow bends, cracks or cracks do not meet higher standards. Due to the different brands of PVC transparent conduits, the matching parts are also different. Different pipe fittings have great differences in the pressure resistance of pipes, and the price of PVC pipes is also different.
In general, PVC pipe fittings have the same brand, and their price and quality are relatively high. Of course, some small brand manufacturers will also reduce the cost and development of matching pipe fittings. PVC pipe has the properties of flame retardant, insulation and shockproof, which can effectively avoid leakage and electric shock accidents.
Widely used in circuit wiring and home protection lines. Pay attention to the following points when using: 1. It is safer to use PVC pipe with pipe fittings when laying pipes. 2. Field materials should be controlled. Flame-retardant plastic pipes shall have continuous flame-retardant signs with a spacing of not more than 1 m and comply with the factory standards of PVC-buried pipeline manufacturers. The inner and outer walls of the pipe should be smooth, free of knurls, depressions, pinholes, and air bubbles. The inner and outer diameters should conform to the national unified standard, and the wall thickness should be uniform. 3. Flame-retardant plastic pipe fittings and ordinary flame-retardant plastic products, such as switch boxes, junction boxes, sockets, pipe fittings, pipe clamps, etc., must be matched with flame-retardant plastic products. 4. The flame-retardant switch box, junction box, pipe joint and pipe clamp have neat appearance, complete reserved holes and no bursting and other damage.
