How to Buy Water Pipes in Hidden Projects

Decoration friends know that there is a project in the home improvement called hidden construction. It refers to buildings, structures, and objects that are hidden behind the surface after they are buried in objects during construction. Hydroelectric reform is one of the hidden projects, in which the repair of water pipes naturally requires water pipes. So, did you pay attention to how to buy water pipes? How to choose a good quality water pipe? What is the material of the water pipe in the house? Now let's look at it with Xiaobian!

First, the classification of water pipe material

The selection and installation of water pipes in “hidden projects” has become one of the issues that cannot be ignored. In order to make the living room look beautiful, people generally use buried wall construction when decorating, and once the water pipe leakage and bursting will bring irreparable consequences.

In the past, pipes used for water supply were mainly cast iron pipes. Sand cast iron pipes are mainly used outdoors, and galvanized iron pipes are used indoors. They can be divided into cold (electric) galvanized and hot galvanized. The galvanized pipe is used as a water pipe. After a few years of use, a large amount of rust is generated in the pipe. The outflow of yellow water not only pollutes the sanitary ware, but also contains bacteria that grow on the rough inner wall. Corrosion causes excessive levels of heavy metals in the water and seriously harms human health. The state has stipulated that sand mold casting fittings and cold galvanized cast iron fittings should be eliminated from June 1, 2000. The use of hot-dip cast iron pipes should be gradually restricted, and aluminum-plastic composite pipes and new-type plastic pipes should be promoted. Therefore, there are three major categories of pipelines currently in use. The first category is metal pipes, such as hot-dip cast iron pipes, copper pipes, stainless steel pipes and so on. The second category is plastic compound metal pipes, such as plastic compound steel pipes and aluminum plastic composite pipes. The third category is plastic pipes, such as PP-R (cross-linked polypropylene high density mesh engineering plastics).
