The difference between PVC water supply pipe and PVC chemical pipe

 The difference between PVC water supply pipe and PVC chemical pipe

Because PVC pipe has many advantages, it is widely used. The common characteristics of PVC chemical pipeline and PVC water supply pipeline are lightweight, good quality, convenient operation, corrosion resistance, good chemical resistance, long service life, smooth inner wall, low fluid resistance, high mechanical strength, good insulation, and sanitary materials, No pollution to water quality, good water tightness, convenient construction, and low maintenance cost.

　Although they are produced with PVC as the main raw material, their requirements are different due to different uses. Now compare the differences between the two.

1. Appearance: It is difficult to distinguish the appearance of PVC water supply pipes and PVC chemical pipes. The main water supply pipes and chemical pipes produced by the company can be distinguished by color and identification. From the color point of view, the color of PVC water supply pipeline is light gray, and the color of PVC chemical pipeline is dark gray.

　　2. Service life: According to national standards, with water as the medium, the service life of PVC pipes for water supply can reach 50 years, and the service life will be reduced correspondingly according to changes in pressure and temperature. For PVC chemical pipelines, due to different media and pressure and temperature changes, the corrosion degree of the pipeline is different. The life of the chemical pipe depends on the actual usage.

　　3. Connection mode: The connection mode of the water supply pipeline is mainly elastic sealing ring connection and glue connection. The elastic sealing ring should be made of a rubber elastic sealing ring that meets the requirements. This connection not only has good sealing performance but also meets hygiene requirements. The connection methods of chemical pipelines mainly include bonding and welding. The adhesive used in adhesive bonding cannot react with the transported chemical liquid. Chemical pipe joints are strictly required to be sealed because if chemical leakage occurs, it will not only cause accidents but also pollute the environment. In fact, the wall of the water supply pipe is printed with drinking water, and the wall of the chemical pipe is printed with industrial use.

The unique advantages of the pvc garden hose we produce:

1 Cold resistance: under normal atmospheric pressure, it does not harden at minus five degrees, and is still soft
2 Light resistance: light-blocking and heat-resistant material, resistant to 65°C, anti-UV and anti-aging.
3 Folding resistance: the pvc hose is flexible, and can be restored to its original shape after being discounted, leaving no creases.

Our pvc garden hoses remain intact after being bent, while other brands of flower pvc garden hoses start to turn white after being bent.

4 Abrasion resistance: The surface coating significantly reduces the friction when dragging the water pipe, facilitates sliding over obstacles, and is not easy to stick weeds or dirt on the surface.

How to flared PVC pipe

 

How to flared PVC pipe

The flaring of the PVC pipe requires the use of equipment. A series of actions complete the conveying of the pipe, lateral transmission, rolling uniform heating, tightening of the PVC pipe, flaring formation, and other working processes. The flaring of the PVC pipe is in the closed molding room. It is carried out in medium and high pressure is adopted. After the expansion of the PVC pipe, it is cooled with circulating water. According to different equipment models and manufacturers, PVC flared pipes are divided into vacuum forming and air-cooling forming. All processes are executed by air cylinder, oil cylinder, or chain drive, limit switch or photoelectric tube realizes fiber control, and time, temperature, and other parameters are set through PLC or computer background program. Ensure that the work of all processes is coordinated, and the flaring of the PVC pipe is completed.

There are three types of PVC pipes: PVC bell end pipes,PVC straight flared pipes, andPVC ring pipes. Only R-port pipes need to use rubber rings, which have the best sealing performance.

pvc bell end pipe

Compared with PVC water supply pipes, PVC drainage pipes have worse toughness. Because they do not need to be under pressure, it is more difficult to expand the ring flaring when flaring, but there is direct flaring.it will be changed PVC bell end pipes.

The construction of swimming pool projects should have both water supply and drainage, and the specifics have to be asked by the engineering technician.

PVC bell end pipe and PVC ring pipe has many standards,

how long does pvc pipe last

pvc pipe

The service life of PVC water pipes is generally more than 15 years. However, there are many factors that lead to different lifespans. The specifics depend on the surrounding conditions of the pipes and whether the environment is severe, such as acid corrosion, high temperature, severe cold, and irresistible external factors, which are all serious threats to the life of PVC water pipes. Factors, all the service life of PVC water pipes is based on a single sentence? From the perspective of the problem, the official answer is that it can be used for more than 15 years.

Normally, the service life of a PVC drainage pipe is determined by the quality of the PVC drainage pipe itself, and the quality of PVC drainage pipes produced by different manufacturers due to factors such as raw materials, technology, and formulas are different.
In order to protect the health of the pipeline market, China has also stipulated the service life of PVC water pipes. The general requirement of PVC water pipes is to guarantee a service life of 50 years.

We are a manufacturer of PVC pipes and fittings. We resolutely prevent inferior pipes from flowing into the market from our workshop. We have stricter requirements on the quality ofPVC drainage pipes, which can be used for 70 years under correct use.
The factors that affect the life of PVC water pipes are nothing more than four points. Below I will help you to explain in detail through a comprehensive comparison so that everyone can understand. I hope that customers who encounter such problems in the future can learn more about Pvc through my article today Water pipe life.

        1. The general service life of PVC

　　 Generally speaking, the service life of PVC is determined by the manufacturer of water pipes and pipes. Of course, different PVC pipe raw materials and production technology used by different manufacturers will also affect the service life of PVC pipes. Once the PVC water pipe industry has entered a stage of rapid development, many manufacturers have made a lot of fake and inferior PVC water pipe decoration materials for profit in order to make money. This also affects its service life to a certain extent. In order to protect the health of the pipeline market, my country also makes provisions for the service life of PVC water pipes. The general requirement for PVC water pipes is to guarantee a service life of 50 years.

　　 2. The relationship between the service life of PVC water pipes and the environment

　　 Although the country has made regulations on the service life of PVC water pipes, it is generally not really used for such a long time in actual use. Many people will find that PVC water pipe material is often used as a concealed project, generally, half of it is buried under the ground, and the other half is directly exposed to the air. The exposed PVC water pipes will gradually become weathered after a long period of wind and sun, while those buried under the ground will probably rot. It can be seen that the PVC water pipe will have a theoretical life and an actual life after indoor installation. The theoretical life is the service life provided by the manufacturer, and the actual life is the actual use time of the PVC water pipe after installation.

　　 3. the relationship between the service life of the PVC pipe and the installation location

　　According to the data, the normal use temperature of PVC pipe is between 0 and 70℃, and the best temperature is between 5 and 60℃. In the four seasons of the year, the temperature is constantly changing, and it is within this temperature under normal circumstances. This is related to the installation position of the PVC water pipe. As for PVC pipe hardware and building materials, it should be installed underground as much as possible during construction, and the supporting pipes should be installed indoors instead of outdoors, and heat sources must be avoided during the installation process, such as installation in the kitchen. Places with heat sources such as gas stoves. When there is no way to install it outdoors, especially in cold winters, PVC pipes must be kept warm. Asbestos, glass fiber, or foam can be used for certain heat preservation measures to effectively extend their service life.

　    4. the relationship between the service life of the PVC pipe and the connection method

In the previous article, I also introduced the connection method and method of PVC pipe, but in fact, the service life of PVC pipe is also related to the installation method, especially when the connection method is bonded, it is best to choose High-quality glue can better ensure the leakage of water pipes during use. Perhaps one or two days of water leakage will not cause a big impact, and the accumulated water leakage that day will affect the material of the PVC pipe itself to a large extent. Therefore, when connecting PVC pipes, a new home improvement material, the glue should be applied to the joint completely and evenly, and the two should be installed together quickly when the temperature is high in summer to avoid the glue in a short time. Kill failure. Only in this way can its service life be guaranteed.
