Water pipe is the key material for home decoration, whether it is new decoration or renovation, water pipe is an important material for our daily water supply.
See how to choose conduit below, buy pair conduit, let household waterway clear and unobstructed.
And the knowledge of choosing and buying water pipe accessories of waterway transformation.
One, water pipe material classification introduction
"Concealed work" is a very important problem, if the water pipe leakage and burst will bring irreparable consequences.
In the past, the main pipes used for water supply were cast iron pipes.
Sand cast iron pipes are used for outdoor and galvanized cast iron pipes are used for indoor.
However, after several years of use, it is easy to produce a large number of rust, breeding bacteria, and seriously harm human health.
The choice of material of visible conduit is very important.
Introduction of water supply pipe
Generally used for household water, now commonly used in the market is PPR inlet pipe, because the water is related to environmental protection, compressive resistance, hot-melt and other issues, so for the choice of the inlet pipe, must pay attention to the indicators in this respect.
The commonly used inlet pipe material is 25mm(6 min) and 32mm(1 inch), which is generally used for the section of the main pipe and can be used in different floors.
Introduction of drainage pipe
Compare with to give conduit, the requirement such as the pressure ability of conduit to material and environmental protection is not tall, the most important reference element is service life.
The main drainage pipes are cast iron pipes and PVC pipes.
According to the specifications, the drain pipe is usually divided into 40mm, 50mm, 75mm, 110mm and so on.
40mm is generally used for table basin launching, floor drain launching and balcony launching;
50mm is generally used for kitchen water;
The 75mm is generally used for the general drainage of kitchen, balcony, table basin, etc.;
110mm is generally used for toilet launching and outer wall launching.
Introduction of drainage pipe
Compared with the feed pipe, the drainpipe has low requirements on material compression capacity and environmental protection, which are the most important
According to the specifications, the drain pipe is usually divided into 40mm, 50mm, 75mm, 110mm and so on.
1. Classification of water pipes: Metal plastics are different
Water pipe is the conduit of water supply, contemporary decorate water pipe is to use construction of type of bury wall, the classification of water pipe has 3 kinds.
The first type is metal pipe, such as inside plastic hot plated cast iron pipe, copper pipe, stainless steel pipe, etc.
The second type is plastic compound metal pipe, such as plastic compound steel pipe, aluminum-plastic compound pipe.
The third type is plastic pipe, such as PB, PP-R.
2, the standard water pipe requirements: in line with the reality is the most important
Water pipe is the concealment project in household adornment, and the water pipe in hutch defends is the indispensable part in the home, domestic water, bath, toilet drain waits to cannot leave water pipe.
However, because of its concealment, the choice of water pipe becomes extremely important.
According to some data, once these hidden works have undergone a renovation, the cost will be more than 10 times of the previous investment.
So standard conduit should accord with what requirement
(1) Economic performance
Water economy can not be measured by the first investment, because it is a "small investment, big loss" product.
Long life, no maintenance, no loss, is the key to the economic performance of water pipes.
If conduit and conduit product cannot be equal with the building life, can bring the loss that water conduit invests 10 times above for the first time to consumer (basically be the loss of decorate material for many times), still may cause the property loss of the family, increase maintenance charge.
(2) Environmental health performance
High quality water pipe materials should not cause pollution to the water supply, and can be used repeatedly, there is no concern about reuse, will not leave a lot of pollution to future generations of garbage and no good way to deal with, we must think for the future generations.
(3) Corrosion resistance
High grade conduit material besides conduit material intensity wants sufficient besides, still must have very strong corrosion resistance performance.
It mainly includes: water resistance, water resistance, air resistance, etc.
Corrosion is the second cause of water pipe leakage, but the first cause of water pipe pollution.
(4) Thermal expansion performance
We use cold water, we use hot water;
The environment we live in also changes with the seasons of the year.
So high quality water pipe material should not be thermal conductivity material, should be coefficient of thermal expansion is small, to environmental temperature and use temperature adaptability is stronger.
High coefficient of thermal expansion is also a cause of leakage.
Two, conduit choose and buy considers main point
Water pipe engineering is a very important engineering problem in the home, involving the water supply and safety issues in the home, so what aspects should be paid attention to in the choice of water pipe?
Mainly from the quality of the water pipe, the construction of water pipe and water pipe installation, maintenance and renovation of convenience and after-sales service four aspects to consider.
1: The quality of water pipes determines the quality of water
"Good water quality, the key depends on the pipeline", the traditional galvanized pipe easy to rust, easy to corrosion, easy to scale, easy to breed microbes, produce secondary pollution, threat to human health.
We often have such experience, no one at home for a few days, turn on the tap, the outflow of yellow rust this is the best example of pipe pollution water quality.
Now the main domestic drinking water pipes are aluminum-plastic pipes and PP-R pipes, because they have corrosion resistance scaling characteristics, widely used in drinking water pipes, but because of the plastic easy doping false.
2: Water pipe construction is the guarantee of durability
Product quality is not equal to engineering quality.
Installation is not in place can make coefficient of product insurance hits big discount, conduit of average household expenses is buried more for dark, can be cheated by not careful, shoddy, consumer can want to take a mind more.
3. Consider the convenience of maintenance and transformation
It is very important to choose a kind of water pipe which is convenient and easy to maintain in case of unreasonable design or inconvenient use.
At present, there are commonly used aluminum-plastic tube and pure plastic tube (such as PVC tube, PPR tube), the aluminum-plastic tube can be bent by hand without rebound, the button is convenient, it is easy to detect the hidden location with metal detector, easy to maintain;
PPR pipe is brittle and fractured due to hot-melt connection. Maintenance and renovation will affect the safety of the entire pipe line, which requires great caution.
After the completion of the construction, it is best to take pictures of the pipeline layout as a record, so as to facilitate maintenance in the future.
4: After-sales service of water pipes
Dare to issue a written product service commitment, from one side to see a product's quality and reputation.
Consumer cannot graph cheapness, buy the conduit that does not have written commitment, general brand conduit has perfect after service, whether to have on quality guarantee letter 50 years quality assures, want to see clear at the same time is double quality assures.
And construction.
We should find a manufacturer with double warranty.
50 years of product quality + construction quality.
Only such a promise, in order to let consumers buy at ease, buy comfortable, with the heart.
As long as we go the right way to buy, you can buy a healthy, durable and secure water pipe.
Third, the high quality water pipe quality chooses the skill
The important step that chooses conduit is how to choose material namely, quality is good the key that conduit is durable.
Want to live in water safety to rest assured again, must pay attention to the identification work when conduit of choose and buy.
Smell: Smell the pipe smell.
Recycled toxic plastics are mixed into the gray pipe, which often smells a pungent peculiar smell.
2 look: the color that sees conduit, ply, glossiness, whether does tube outer wall indicate trademark, specification, temperature, pressure, production batch number, produce date and actual place of production, aluminous model tube sees aluminium layer thickness even, evenness, 2 look to have sanitation permit.
Water pipes without a sanitation permit cannot be used in drinking water pipes.
Three notes: one should pay attention to the formal authorized distribution of the pipe shop purchase shop;
Second, pay attention to whether the purchased pipe and fittings are produced by the same manufacturer;
Third, pay attention to obtain the product service card.
Iv. Introduction of common water pipe fittings
In addition to water pipe, water pipe fittings should be used in waterway reconstruction.
A lot of the owner that oneself are in charge of buying building materials, when needing to buy conduit fittings, often because do not understand, and buy wrong breed, model.
So the water pipe fittings that still understands commonly used below has what.
1, direct
Also known as a casing joint, it can be used to extend a pipe if it is not long enough.
When using, pay attention to match the size of the pipe. When the pipe is not long enough, connect two pipes.
2, elbow
It is used to make the pipe turn, because the pipe itself is straight, can not bend, to change the direction of the pipe, can only be achieved through the elbow.
The routine is divided into 45 degree and 90 degree elbows.
3. Inner and outer filaments
Is a complete set of use, connect faucet, water meter, and other types of water pipe will be used, and most of the use of home decoration are internal silk pieces.
4, t
As the name suggests, it is used to connect water pipes in three different directions. It is used when leading a water way from a water pipe.
5. Big and small heads
It is used to connect two pipes with different pipe diameters, direct, elbow and tee have the branch of big and small head.
6, plug
After the installation of the water pipe, it is used to temporarily close the outlet. When installing the faucet, it will be removed. When using the plug, the size should be matched with the corresponding pipe fitting.
7. Winding and bending
Also known as crossing bridge, when two water pipes intersect at the same plane but do not butt, in order to ensure the normal use of water pipes, we use curved transition, just like an arch bridge, to avoid the direct intersection of water pipes by avoiding the plane.
8. Stop valve
The function is to open and close the current;
The function of pipe clamp is to fix the position of water pipe and prevent water pipe from shifting.
9. S-bend and P-bend
Generally used for water bucket and sewer link, have the function of anti-odor, S bend is generally used for dislocation link, and P bend is a deodorant link.Its function is to prevent blocking, anti - odor.
