1、PVC conduit pipe introduction:
PVC pipe threading refers to the PVC resin as the main raw material, adding other additives by extrusion molding, wire and cable for straight conduit to protect below 2000V industrial and construction engineering, has been widely used in recent years in the family tube wear protective interior decoration and construction of hydropower installation etc..
2、PVC conduit sizes
3、Precautions for installation of PVC electrical pipe:
1, of course, the most important thing is to use threading pipe embedding.
2, walk the line should grasp the "circuit between the two ends of the nearest distance on line", not without winding, it will not only cause deadlines, but also increases the power to change the input.
3, a threading pipe does not wear too many lines, should be pulled after the line, to see whether it can easily pull.
4, the joint line must leave cassette under the joint buckle panel, days after the replacement and maintenance are convenient.
5, the diameter is less than 25 PVC pipe bend pipe line used to wear, not with elbow bend, right angle bending die tend to cause a deadline
4、PVC conduit pipe characteristics：
1). strong resistance to pressure: high impact resistance of medium-sized pipe series can withstand strong pressure.
2). corrosion resistance, insect pest resistance: has the resistance to general acid and alkali properties.
3). flame retardant performance is good: PVC tube left on the flame, the natural fire spread along the pipeline.
4). strong insulation performance: can withstand high voltage without being broken, effectively avoid leakage, electric shock dangerous.
5). simple construction:
Weight diameter: easy to transport vehicles and human transport, construction and installation of light and labor-saving.
Easy bending: as long as a tube spring is inserted into the tube, it can be bent artificially at room temperature.
Easy splicing: a special tube cutter is used to connect the PVC tube to the desired shape quickly and conveniently.
