What is the reason why PVC threading pipe is soft

The threading pipe is generally stuck with a pipe clamp at a certain distance. The pipe clamp is fixed to the wall. Use pipe clamps to standardize the wiring of PVC pipes, and leave a line of PVC pipe length at a certain distance, which is convenient to repair if there is a problem in the future.

Composition of PVC threading pipe: resin powder, calcium powder, stabilizer, wax, stearic acid, CPE, ACR, brightener, TiO2, etc.

PVC is polyvinyl chloride, English abbreviation PVC (polyvinyl chloride), is vinyl chloride monomer (VCM) in peroxide, azo compounds and other initiators; or polymers polymerized under the action of light and heat according to the reaction mechanism of free radical polymerization. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively known as vinyl chloride resins. The material is an amorphous material.

PVC materials are often added with stabilizers, lubricants, auxiliary processing agents, pigments, impact inhibitors and other additives in practical use. It has non-flammability, high strength, resistance to climate changes and excellent geometric stability. PVC is highly resistant to oxidants, reducing agents, and strong acids.

However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and is not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons.

Cheap wire pipes have no toughness, cannot be bent, and are brittle when cold; The medium one can be bent, but the maximum amount is about 90 degrees, and the *** line pipe can be bent more than 100 degrees to 360 degrees is not a problem.

PVC corrugated threading pipe, white coil by coil, small diameter is the majority.

Hello dear! Is it good to have a soft or hard cable pipe, and I think it's good to have a hard line 1Hard wire through the pipe is easier to operate than the soft wire, in accordance with the electrical installation standard specifications of the construction, the soft wire joint needs to be crimped or welded, the soft wire through the pipe after the joint electrician is difficult to do, so it is better to hard wire.

2.It is hard to know that the pure wire diameter is thick enough, the insulation material is strong and reliable, not easy to damage, and there is no problem at all when used under long-distance fixed lines. 3.

A hard wire is a single-strand wire with a thick diameter, low cost, and is also cheaper than a soft wire. 4.The hard wire is a solid core, and the wire and wire joints are more reliable, and there will be no false connections and punctures like soft wires.

5.The interface for installing the switch panel is designed according to the hard wire, which will be more convenient. 6.

The hard wires are rich in color and can distinguish different circuits. 7.The zero fire ground of the soft wire is wrapped together, which is not conducive to laying alone, and the hard wire is more standardized, convenient and material-saving.

1.The wire selling round pipe is not in line with the middle and collapsing, and it is difficult to pass through too many turns.

2.If there are too many wires in the conduit, it will be difficult to thread them if they affect each other.

3.The quality of the wire is not good, the copper content is low and there are many impurities, and the wire is stiff and not flexible, which will lead to the difficulty of threading.

The disadvantages of PVC threading pipes are that they are not suitable for hot water pipes, although they can be used as domestic water supply pipes, they are not suitable for direct drinking water supply pipes. Although this type of pipe has good hardness, it is easy to brittle under impact. Some low-quality counterfeit PVC pipes are added with plasticizers during production, which will cause media pollution and greatly shorten the aging period of PVC pipes.
