Part 1: Pay attention to quality and health and optimize the material of water supply pipe.
Water supply pipeline refers to the water inlet pipeline in the home, which provides the water needed for home life. The choice of water supply pipeline can't be casual. Let's take a look at the matters needing attention in the selection of water supply pipeline.
A, water supply pipeline selection matters needing attention
The water supply pipeline is a pressure pipeline. After the construction is completed, it is necessary to carry out pressure test, which requires high quality such as pressure resistance of the pipeline. At the same time, many families directly use the water in the water supply pipe as drinking water, so whether the water supply pipe will cause secondary pollution to the water and whether the pipe made of this material will affect the health is also a key consideration for the owners when purchasing the water supply pipe.
1, safety and reliability of pipelines
The water supply pipeline in home decoration is a pressure pipeline. Once the pressure resistance of the pipeline is not enough, the pipeline may burst and leak. Therefore, the selection of water supply pipes for home decoration depends not only on the strength and mechanical properties of the pipes, but also on the quality properties such as aging resistance and heat resistance. High-quality water supply pipeline should be able to withstand vibration impact, water hammer, thermal expansion and cold contraction. , and can withstand the test for a long time, no water leakage, no burst.
2. Health and safety of pipelines
Water supply companies produce qualified drinking water and deliver it to thousands of households through water supply pipelines. If inferior pipes are used in home decoration, it is likely to cause secondary pollution of water, and the quality of terminal drinking water will be difficult to guarantee. Therefore, when selecting water supply pipeline, it is necessary to focus on whether the pipeline will cause harm to human health.
Second, the more suitable water supply pipeline at present.
1, PPR tube
PPR tube has outstanding physical properties, non-toxic, light weight, pressure resistance and corrosion resistance. It is not only suitable for cold water pipes, but also for hot water pipes and even pure drinking water pipes. The interface of PPR pipe adopts hot melt technology, and the pipes are completely fused together, so once the installation and pressure test pass, there will be no aging and water leakage like aluminum-plastic pipe. In addition, PPR pipe is cheap and easy to install, and it is a widely used water supply pipe for home decoration at present.
Bian Xiao reminded: At present, there are many PPR tube manufacturers in the market, and there are also many inferior PPR tubes produced by bad manufacturers. Therefore, car owners need to pay attention to screening when purchasing, and it is best to choose brand products with good reputation. In addition, distinguish between hot and cold water pipes when purchasing. Hot water pipes can be used at the time of purchase, and hot water pipes can also be used as cold water pipes, but cold water pipes cannot be used as hot water delivery pipes.
2. Copper tube
Copper tube has outstanding physical properties such as corrosion resistance and sterilization, and is the first-class product in water pipes. However, due to the high price, complicated installation and construction, the utilization rate is not very high.
3, stainless steel tube
The performance of stainless steel pipe is similar to that of copper pipe, and it has the advantages of excellent corrosion resistance, sanitation, no rust, no scaling, no dialysis, no release of foreign substances, good self-cleaning, long service life and environmental protection. However, the price of stainless steel pipes is relatively high, and the construction is difficult, so the use penetration rate is not very high.
The second part: It is the most important to choose the drainage pipe material for long-term use.
Household drainage pipes are generally used as sewage pipes and belong to pressureless pipes. Blank houses generally have preset drainage pipes, but when decorating, it is often necessary to buy some drainage pipes according to the needs of design. Let's take a look at what we should pay attention to when choosing a drain pipe relative to a water supply pipe.
A, drainage pipe selection matters needing attention
1, pay attention to service life.
Compared with the water supply pipe, the drainage pipe is used to discharge sewage, so the requirements for the compressive strength, environmental protection and hygiene of the material are not high. The most important thing is that it has strong anti-aging ability and long service life. If the drain pipe leaks, it is likely to affect the residents downstairs, and it is more difficult to maintain it. Therefore, when choosing a drain pipe, you should not be careless.
2, choose the appropriate specifications
There are many specifications of drainage pipes, which are usually divided into 40mm, 50mm, 75mm, 1 10mm, etc. 40mm is generally used for basin launching, floor drain launching and balcony launching; 50mm is generally used for kitchen launching; 75mm is generally used for the total drainage of kitchens, balconies and basins. 1 10mm is generally used for toilet water and exterior wall water. When purchasing, it is necessary to purchase according to the requirements and specifications of the positions used.
Second, the current more suitable drainage pipeline.
1, UPVC tube
At present, UPVC materials are usually used in sewer pipes. UPVC pipe has the characteristics of acid resistance, alkali resistance, strong corrosion resistance, good pressure resistance, high strength, light weight, low price and small fluid resistance, and has the characteristics of long service life and corrosion resistance that cast iron pipe can't compare with. In construction, it has the advantages of light weight, convenient transportation and processing, simple connection and so on.
Bian Xiao reminds: Connecting glue is very important.
When UPVC pipe is used as sewer pipe, attention should be paid to the selection of matching adhesive. U-PVC and U-PVC pipes should be connected with special U-PVC glue, evenly brushed with a small brush, and then connected tightly. If the U-PVC pipe is connected to the original sewer pipe of the same material, special U-PVC glue should also be used. If the original sewer pipe is cast iron pipe, it is recommended to seal it with glass glue. Because glass glue has good waterproof and sealing performance and certain elasticity, it can ensure that water does not leak and stink.
2, cast iron pipe
Cast iron pipe is made of pig iron with high strength and long service life, and can also be used as drainage pipe. However, due to the complicated construction and high labor cost, it is not the mainstream choice for sewer pipes.
Part3: Although the water supply and drainage fittings are small, they are very important and are the first choice.
In addition to pipelines, one of the main materials used in waterway reconstruction is pipe fittings. Pipe fittings are accessories needed to change the direction of waterway, increase water outlets and connect interfaces. Although these are small pieces, according to experts, more than 90% of the water leakage incidents are related to the pipe fittings at the interface, and the owners should not be careless when purchasing.
I. Introduction of Common Waterway Fittings
According to the purpose, pipe fittings are mainly divided into 9 types: straight-through, tee joint, elbow, winding pipe, valve, pipe clamp, pipe cap, adapter and raw material belt.
Among them, straight-through, tee joint, elbow and winding pipe have four forms: ordinary type, internal type, external type and variable diameter type respectively. The so-called common form means that the dimensions and materials at both ends of the pipe fittings have not changed; Inner wire is also called inner tooth, and those pipes with metal grooves at one end can be called inner wire. Opposite to the inner wire is the outer wire, also called the outer tooth, that is, one end of the pipe has a metal flange; Reducing diameter means that the dimensions of both ends of the pipeline are inconsistent.
Second, the waterway pipe fittings purchase skills
There are many pipe fittings used in waterway reconstruction. Although the price of a single pipe fitting looks very low, the total price is generally not low because of the large number. Therefore, avoid buying inferior products when purchasing. When purchasing, please refer to the following purchase methods.
1, pay attention to support
When selecting pipe fittings, you must choose the pipe fittings that match the waterway pipeline, and it is best to choose the matching pipe fittings with the same brand and material.
Step 2 look at the appearance
When buying pipe fittings, first look at whether the color and luster are uniform; See whether the pipe wall thickness is uniform and whether the pipe wall is smooth; Threaded pipe fittings should also pay attention to whether the threads are evenly distributed.
Step 3 choose a brand
When purchasing pipe fittings, first of all, read the product manual and certificate carefully to understand the performance index of the product. The safest way is to go to a large formal market to buy materials.
