How to choose PVC pipe & how to maintain it?

PVC pipe refers to a pipe product made of polyvinyl chloride resin and stabilizer through plastic extrusion. PVC pipes are light in weight, convenient in transportation, labor-saving in installation, small in fluid resistance, and smooth in drainage. Compared with cast iron pipes of the same diameter, the flow rate can be increased by 30%, and they have high practicability, so they have also won the favor of the market.

How to choose PVC pipe?
let’s start!


First of all, observe the appearance of the pipe, such as the common white PVC drainage pipe on the market, the poor quality pipe is white or yellowish, uneven in color, brittle and hard, and the inner wall is rough and has small holes. The color of high-quality products should be milky white and uniform, and the inner and outer walls are relatively smooth and flat.


Inferior-quality PVC pipes, in order to save costs, excessive calcium powder was added during pipe production, and inferior pipes are cheap and easy to break. High-quality PVC pipes have sufficient toughness, and the hardness and toughness of the pipes are very strong. The heavy pressure test will flatten but will not break.


To check whether the wall thickness of the pipe is consistent with the packaging instructions, whether it has a complete printed mark and relevant implementation standards

04/Corrosion Resistance

Good pipes have corrosion resistance to chemicals (including strong acids, strong alkalis, etc.). And it is not attacked by fungi and bacteria, termite-resistant, weather-resistant, tasteless, odorless, and non-toxic. Under normal use conditions, the service life can reach more than 30-50 years.

How are PVC pipe fittings maintained?

The scope of application of PVC pipes and fittings is very wide. No matter how good the water pipe is, no matter how good the installation technology is, without good maintenance, the service life of PVC can be greatly reduced. To prolong the service life of perfusion, you need to learn its maintenance methods.

1.Prevent Clogging
Drain clogs are common, but one of the causes of clogs is a foreign object stuck to part of the pipe. Blocked water pipes will not only bring problems to our lives, but the local pressure of the water pipes will be too high, which will affect the life of the water pipes. In order to avoid clogging, we can add a branch flow at the drain to prevent large foreign matter from entering the water pipe.
2.Prevent Stress
The hardness of PVC continues to increase, but if the external pressure is too large, it may rupture and leak. When installing water pipes, if you install water pipes on the top of the room as much as possible, you can not only prevent water pipes from breaking and leaking due to heavy pressure, but also avoid the huge cost of patting the ground to repair water pipes after water leakage.
3.Sun Protection to Prevent Breakage
Long-term exposure will not only lead to PVC aging and performance degradation, but also because sunlight penetrates the pipe wall to provide conditions for a large number of microorganisms to multiply, causing moss to grow on the water pipe, affecting use. Plastic becomes brittle in cold weather, and once ice forms in the pipes, the pipes can rupture.
To prevent long-term exposure or over-cooling of PVC, do not lay exposed water pipes, or put insulation material packaging in exposed places, and drain the water in the water pipes at night in winter.
