Renovation of water and electricity can not know the knowledge of water pipes and accessories
Decoration of the waterway transformation is the main event, that can not be ignored. And to do a good job of waterway transformation, waterway decoration materials purchase is very critical. May be a lot of owners will feel like buying a good water pipe, it is not true, in addition to water pipe water transformation also need a variety of water pipe fittings. Although these accessories are inconspicuous, but indispensable. Xiaobian together with the following to understand when the home appliances need to use the water pipe accessories.
Get started with water pipes and accessories
Waterway materials are mainly divided into water supply pipe, drainage pipe, pipe fittings three categories, water supply pipe is the home of the water pipe, drainage pipe is used to discharge sewage, and pipe fittings are used in the pipe, for the connection, turn, etc. Multiple effects.
1, water pipe material classification
For waterway materials, we must first look at what its material is what. At present, the main pipe and pipe fittings metal pipe, plastic pipe, plastic composite pipe three, one of the plastic pipe is the mainstream choice.
Comparison of Three Kinds of Water Pipe Materials
Material: brass, galvanized pipe
Advantages and disadvantages: strong water repellency, acid and alkali resistance, earthquake resistance, crack resistance, insulation system compatibility is very good. But the tool to draw it when there will be scratches, prone to hollowing out.
Scope: brass suitable for drinking water pipes, galvanized pipe can not be drinking water pipes
Material: PPR tube
Advantages and disadvantages: non-toxic, light weight, pressure, corrosion resistance. But the construction technology requirements are high, need to use special tools and professional construction, in order to ensure system security.
Scope: for hot water pipes, and even pure drinking water pipes
Plastic composite pipe
Material: Aluminum-plastic composite pipe
Advantages and disadvantages: insulation performance, easy to corrosion, easy construction, excellent high temperature performance, pressure is not very good, the construction of a through a rigorous pressure test.
Scope: should be made for construction or buried in the wall, should not be buried underground.
In the past, the pipes used for water supply were mainly cast iron pipes. But because of the use of a few years after the easy to produce a lot of rust, breeding bacteria, serious harm to human health, has been gradually eliminated. The PPR pipe with the traditional cast iron pipe, galvanized steel pipe, cement pipe and other pipelines, compared with energy-saving materials, environmental protection, light high strength, corrosion resistance, smooth wall does not scale, construction and maintenance is simple, long life and other advantages , Has now become the main force of water pipe material.
2, water supply pipe introduction
Generally used for household water, and now the market is commonly used in the PPR inlet pipe, because the water involved in environmental protection, compression, hot melt and other issues, so the choice of water pipes, we must pay attention to this indicator. Commonly used inlet pipe for the 20mm (quarter) and 25mm (6 points), 32mm (1 inch) is generally used for a section of the main, in different floors will be used.
3, drainage pipe introduction
Compared with the water pipe, the drainage pipe on the material compression capacity and environmental requirements are not high, the most important reference factor is the service life. Drain pipe mainly divided into two kinds of cast iron pipe and UPVC pipe. Drain pipe in accordance with the specifications, usually divided into 40mm, 50mm, 75mm, 110mm, 40mm generally used for basin water, floor drain and balcony decoration renderings) water; 50mm general for the kitchen decoration renderings) Of the general for the kitchen, balcony, basin, etc. of the total drainage; 110mm is generally used for toilet decoration renderings) water, wall water.
4, water pipe fittings introduced
In addition to pipe, the waterway transformation also used a large material is the pipe. Pipe fittings is the waterway to change, increase the outlet, connect the interface required to use the accessories, a wide range of names are not uniform. More than 90% of the running water, water leakage events and the interface of the pipe, so consumers can not be sloppy in the purchase. Decoration of the waterway transformation is the main event, that can not be ignored. And to do a good job of waterway transformation, waterway decoration materials purchase is very critical. Understand the type of pipe knowledge, for the purchase, it is essential. The next step is to understand some of the skills to buy to help you buy quality products.
