Waterway reconstruction pipe is preferred to ensure the quality of home improvement

Part1: Focus on quality and health, preferred for water pipe materials

The water supply pipe refers to the water inlet pipe in the home, providing the water needed for home life. The selection of the water supply pipe can not be casual. Let's take a look at the considerations for the water supply pipe.

I. Considerations for the selection of water supply pipes

The water supply pipe is a pressure pipe, and the pressure test is required after the completion of the construction, and the quality requirements for the pressure resistance of the pipe are high. At the same time, many households directly use the water in the water supply pipe as drinking water. Therefore, whether the water supply pipe will cause secondary pollution to the water, whether the pipe with the material will affect the health is also a key consideration for the owner when purchasing the water supply pipe. .

1. Safety and reliability of pipes

The home supply water supply pipe has a pressure pipe. Once the pressure resistance of the pipe is insufficient, there may be a case where the pipe bursts and leaks. Therefore, the choice of home improvement water supply pipe, the first depends on the strength and mechanical properties of the pipe and anti-aging, heat and other quality properties. High-quality water supply pipes should be able to withstand vibration shock, water hammer and thermal expansion and contraction, and can withstand long-term tests without leakage or bursting.

2, the health and safety of the pipe

The water company produces standard drinking water that is delivered to thousands of households through water pipes. If the inferior pipes are used in the decoration, it is likely to cause secondary pollution of the water, and the quality of the terminal drinking water will be difficult to guarantee. Therefore, when selecting the water supply pipe, it is necessary to focus on whether the pipe will cause damage to human health.

Second, the current suitable water supply pipe

1, PPR tube

PPR pipe has outstanding physical properties. It is non-toxic, light, pressure-resistant and corrosion-resistant. It is not only suitable for cold water pipes, but also for hot water pipes and even pure drinking water pipes. The interface of the PPR tube adopts the hot-melt technology, and the tubes are completely fused together. Therefore, once the installation pressure test is passed, it will not exist as long as the aluminum-plastic tube has a long time aging and water leakage. In addition, the PPR pipe is relatively inexpensive and easy to install, so it is a widely used home improvement water supply pipe.

Xiao Bian reminds: At present, there are many PPR pipe manufacturers on the market, there are many inferior PPR pipes produced by bad manufacturers, so the owners need to pay attention to the screening when purchasing, it is best to choose brand products with good reputation. In addition, the hot and cold water pipes need to be separated when purchasing. Hot water pipes can be used when purchasing, and hot water pipes are also used for cold water pipes, but cold water pipes cannot be used as hot water transportation pipes.

2, copper tube

The copper tube has the advantages of corrosion resistance, sterilization, and the like, and has outstanding physical properties, and is a superior product in the water pipe. However, due to high prices and complicated installation and construction, the penetration rate is not very high.

3, stainless steel tube

The performance of the stainless steel tube is similar to that of the copper tube. It has excellent corrosion resistance, hygienic type, no rust, no scaling, no dialysis, foreign matter, good self-cleaning, long service life and environmental protection. However, the price of stainless steel pipe is good. It is also relatively high, and construction is difficult at the same time, so the penetration rate is not very high.

Part2: Use long-lasting and most important preferred drainage pipe material

The drain pipe of the household is generally used as a sewage pipe and belongs to a non-pressure pipe. Rough houses generally have a certain set of drain pipes, but in the decoration, according to the design needs, it is often necessary to purchase some drain pipes. Let's take a look at what should be paid attention to when the drainage pipe is purchased relative to the water supply pipe.

First, the consideration of the selection of drainage pipe

1, pay attention to the service life

Compared with the water supply pipe, the drainage pipe is less stressed and used for sewage discharge. Therefore, the pressure resistance and environmental sanitation of the material are not high. The most important point is that the anti-aging property is strong and the service life is long. . If there is water leakage in the drainage pipe, it is likely to affect the downstairs residents, and the repair is more difficult. Therefore, when purchasing the drainage pipe, you should not be careless.

2, choose the right specifications

Drainage pipes are available in a variety of sizes and are usually classified into 40mm, 50mm, 75mm, 110mm, etc. 40mm is generally used for basin water, floor drain water and balcony water; 50mm is generally used for kitchen water; 75mm is generally used for kitchen, balcony, basin, etc.; 110mm is generally used for toilet launching, external wall launching . When purchasing, you need to purchase according to the required specifications of the location you are using.

Second, the current more suitable drainage pipe

1, UPVC pipe

UPVC pipes are generally used in the current water pipes. UPVC pipes have the characteristics of acid resistance, alkali resistance, corrosion resistance, good pressure resistance, high strength, light weight, low price and low fluid resistance, and are incomparable with cast iron pipes. Long life and corrosion resistance. In the construction, it has the advantages of light weight, easy transportation and easy connection.

Xiaobian reminder: connecting glue is very important

When using UPVC pipe as the down pipe, you need to pay attention to the matching adhesive. U-PVC and U-PVC pipe joints should be made of special U-PVC glue, evenly spread with a small brush and then tightly connected. U-PVC pipe and original down pipe connection If the material is the same, use special U-PVC glue. If the original down pipe is cast iron pipe, it is recommended to seal with glass glue. Because the glass glue has a good waterproof sealing and a certain elasticity, it can ensure that the water does not leak or return.

2, cast iron pipe

Cast iron pipe is made of pig iron as the main raw material, with high strength and long service life. It can also be used as a drainage pipe. However, due to the complicated construction and high labor costs, it is not the choice of the current mainstream plumbing.

Part3: Although the pipe fittings are small, the water supply and drainage pipe fittings are important.

In addition to the pipe, a large material to be used in the waterway transformation is the pipe fittings. The pipe fittings are the accessory parts that need to be used when the waterway is redirected, the water outlet is added, and the interface is connected. Don't look at these are small pieces, but according to experts, more than 90% of the running water and water leakage incidents are related to the pipe fittings at the interface, so the owner can not be sloppy at the time of purchase.

First, the introduction of common water pipe fittings

According to the use, the pipe parts are mainly divided into straight, three-way, elbow, winding pipe, valve, pipe clamp, pipe cap, adapter and raw material belt.

Among them, the direct, the three-way, the elbow, and the curved pipe are respectively in the form of ordinary, inner wire, outer wire and different diameter. The so-called common form means that the size and material of the ends of the pipe are not changed; the inner wire is also called the inner tooth, and the pipe fittings with the metal groove at one end can be called the inner wire; the outer wire is the outer wire, also called The outer teeth, that is, the end of the pipe has a metal flange; the different diameter is the size of the ends of the pipe is inconsistent.

Second, the water pipe fittings purchase support

There are quite a few pipe fittings used in the waterway reconstruction, and although the individual pipe fittings seem to be inexpensive, the total price is generally not low due to the large number. Therefore, you need to avoid buying inferior products when purchasing. You can refer to the following shopping methods when purchasing.

Short-wave Pass Linear Gradient Filter

The short-wave pass linear gradient filters are continuously coated to achieve spatially continuous variation of filtering characteristics based on a multi-layer wedge-shaped film structure. The slope of the film can be adjusted according to the dispersion requirement to obtain the target linear rate of change. The Linear Gradient Filter is highly integrated and has an irreplaceable advantage in the miniaturization and lightweight design of spectroscopy instruments.
