Practical Application Of PVC Materials

Advantages of UPVC pipe fittings and pipe materials

Portable: the proportion of UPVC material is only 1/10 of that of cast iron.

Excellent chemical resistance: UPVC has excellent acid-base resistance performance, except near saturation point strong acid-base or strong oxitargets agents atmaximun.

Non-conductive: the UPVC material cannot conduct electricity and is not corroded by electrolysis and current, so no secondary processing is required.

Not to burn, not to fuel, no fire concerns.

Brand new PVC material

Brand new PVC material

Simple installation, low cost: easy cutting and connection. The practice of PVC glue connection proves reliable and safe, easy operation and low cost.

Durability: good weather resistance and can not be corrupted by bacteria and fungi.

Low resistance, high flow rate: smooth inner wall, low fluid loss, dirt is not easy to adhere to smooth pipe wall, easy maintenance, low maintenance costs.

Commonly used specifications

The conventional specifications of common PVC pipe drain pipes are as follows: 32mm, 40mm, 50mm, 75mm, 90mm, 110mm, 125mm, 160mm, 200mm, 250mm, 315mm respectively. The length of pvc-u pipe is generally 4m or 6m, and the other length shall be determined by both parties through negotiation.

Production standard

National standard: GB/T5836.1-2006

Identification of PVC pipe

1: first, look at the surface finish and whiteness.

2. If you take the sample and break it easily, it is usually high calcium product. Of course, it is ok to meet your requirements if the price is appropriate.

3. Take the sample and step on the side of the pipe with your foot to see if it can crack, or the elongation at break after cracking. (generally, you have to set up the relationship first, ha-ha, otherwise people won't let you step on it.)

4: fire resistance is very troublesome. The most direct way to do this is to take a high temperature, high light place for a few days and see how much the surface changes, but it's a waste of time. Let's focus on the first three terms. The brand is really good, but the products of some small factories are also very good. I suggest you learn how to distinguish the good from the bad

PVC pipe leakage treatment

Step 1: find out where the water is leaking. Water leakage always has a source bar, general conduit is embedded in the wall inside, when conduit leaks, metope is qin dampness, but still can see water leakage place in what place. The water is coming down from the top, so you can still find the leaking pipe by following the wet mark on the wall all the way.

Step 2: mark leaking pipes. If the water pipe is really in the wall, it is necessary to invite workers to punch holes and open the wall. If a leaking pipe is outside the wall, that's fine. Check what the pipes are made of. Such as plastic, steel, PV and so on.

Step 3: waterproof tape. This one can be bought at the hardware store. It's very cheap. Outside the leaky pipes with waterproof tape first (also known as waterproof paper) wrapped in several layers, and then use foam wrapped in a layer in the outside, and then on the outside of the foam wrapped with waterproof paper, then a layer on the outside of the waterproof paper in foam plastic coated, finally hit the glass glue is OK!
