UPVC pipes and fittings

The insurmountable drawbacks of UPVC pipes. With the continuous deepening of reform and opening up, people's living standards are constantly improving, and the requirements for the quality of tap water are also increasing. In addition to ensuring that the produced water meets the standards for drinking water, the water supply industry must also ensure that the water transported through the pipeline network is qualified. People have a strong reaction to phenomena such as' yellow water 'and' black water 'in tap water, and the main reason for the deterioration of water quality in the pipeline network is the corrosion of water supply pipelines, especially cold galvanized pipes. The coating on the inner wall of the pipes is unstable, and the pipes start to rust after only a year or so of use, causing an iron smell and color in the water. The corrosion of galvanized pipes buried underground is even more severe. And UPVC pipes are corrosion-resistant. Not scaling, can inhibit bacterial growth, and is beneficial for protecting water quality from secondary pollution of pipelines. So UPVC pipes have a wide range of application prospects, especially for a large number of buried pipes in front of users' water meters.

In addition, UPVC pipes are also lightweight. The advantage of convenient transportation. The specific gravity of UPVC pipe is about 1.4 (the specific gravity of cast iron pipe is about 7.4), which is one-fifth of the weight of cast iron pipe. Using UPVC pipe can save 1/10-1/5 of transportation costs compared to cast iron pipe. It is very convenient for handling, loading and unloading construction. The construction environment for water supply pipelines is often harsh, and the construction site is muddy. It would be ideal to reduce the labor intensity of workers and shorten the construction period. And using UPVC pipes can achieve this ideal. UPVC pipes are lightweight and can be manually moved during installation, generally without the need for machinery. For example, a DN200 6m long UPVC pipe weighs about 55kg, while a cast iron pipe of the same diameter and length weighs 304kg. During installation, one person can carry the UPVC pipe, while the cast iron pipe requires three people or machinery to be lowered. This greatly reduces the labor intensity of workers and saves time and construction costs.
