Select Category pipeline renovation

 For home decoration , it was meant mainly to the sewer water pipe sections. Now the market streaky one hundred pipe material , users often can not touch the clue. So what exactly are those types , there are those appropriate to use it ? Here and Sally went to see a detailed analysis .

A pipe type

1 , galvanized iron pipes

Galvanized iron pipe is a maximum amount of material to use , due to the galvanized iron pipe corrosion caused by high levels of heavy metals in water , affecting human health , governments in many countries and regions have begun to explicitly prohibit the use of galvanized iron pipes . At present, China is gradually phased out this type of pipe exterior flooring options.

2 , brass

A more traditional but the price is more expensive piping materials, durable construction and more convenient . In many imported sanitary products, brass is the first choice. Price is the main reason affecting their usage , and the other hand is also a factor in copper corrosion .

3, stainless steel pipe

Stainless steel is a material more durable piping . But its high price , and the construction process is relatively high , the material strength of its still hard, very difficult scene processing . Therefore, the probability of the renovation project was selected low.

4 plastic composite pipe
Plastic composite pipe is a pipe market is more popular because of its light weight, durable and facilities
Workers convenient, its flexibility is more suitable for use in home decoration . Its main disadvantage is that as the hot water pipe
With time , due to the long wall of thermal expansion and contraction will cause dislocation resulting in leakage wpc floor tiles in singapore.

5, stainless steel composite pipe
Stainless steel composite pipe and plastic composite pipe in the structure is similar to a certain extent , the performance is relatively
Similar. Similarly, the intensity of the problem of steel, construction technology is still a problem.

6, PVC pipe
PVC ( polyvinyl chloride ) plastic pipe is a modern synthetic material pipes. But in recent years the scientific community found
Can become more flexible PVC phthalate chemical additives on the human body kidney, liver, testicles great impact ,
Cause cancer , kidney damage , destruction and recycling system of human function , affecting development. In general, the
Its strength is far from suitable for mains pressure requirements, so rarely used in water pipes . Large
In some cases , PVC pipe for wire and pipes and sewage pipes .

7, PP pipe
PP (Poly Propylene) tube is divided into multiple , are:

1, PP-B ( block copolymer polypropylene ) As a result of welding technology in the construction , it is also commonly known as hot-melt tube . Because of its non-toxic, light, pressure, corrosion resistance , is becoming a promotional material , but the choice is still relatively small renovations , in general , this material is not only suitable for cold water pipes, also suitable for use in the hot water pipes , and even clean drinking water pipeline .

2, PP-C ( modified copolymer polypropylene ) pipes , basic performance above.

2, PP-R ( polypropylene random copolymer ) tube , the performance of basic Ibid .

PP-C (B) PP-R and physical properties substantially similar to , the same application , the project can be used interchangeably. The main difference for the PP-C (B) low temperature brittle material than PP-R; PP-R materials at high temperature resistance PP-C (B). In practice , when a liquid medium temperature ≤ 5 ℃, the preferred PP-C (B) pipe ; When the liquid medium temperature ≥ 65 ℃ , the preferred PP-R pipe ; When the liquid medium temperature of 5 ℃ -65 ℃ time area , PP-C (B) consistent with the performance of PP-R .

Second, the pipeline installation considerations

In decoration, waterproof often more important than any of those topics. In the pipeline installation and use need to pay attention to those matters it wood composite doors china?

1, install piping must find professional mechanics . No matter how luxurious your grade , if you are not willing to use in this regard is not worth the money . Often Pulie pipes or leaking water pipe itself will cause the price several times, hundreds of times , and even the loss of thousands of times .

2 , the installation must be pressurized testing. Pressurization test is generally 1.5 times the water pressure in the case progresses, the test should be no leaking.

3 , the pressure conditions in the absence of test methods :
1 ) Turn off the main valve pipes . ( Ie water meter in front of the pipe switch )
2 ) Open the taps inside the room for 20 minutes, to ensure that no water again after dropping off all taps.
3 ) Turn off the toilet tank with water and washing water switch -enabled devices .
3 ) Turn on the water main valve .
4 ) After opening the main valve 20 minutes to see if the meter walk , including a slow walk .

If you have to move , that is leaking . If you do not move, that is fine.
4 , in daily use , if we find the following cases , inspect the pipeline as soon as possible :
1 ) wall paint surface mold out bulbs.
2 ) baseboard or flooring surface appears black and fine bubbles .
