UPVC air duct

· Product advantages

UPVC pipe is a plastic pipe made from polyvinyl chloride (PVC) resin without plasticizers. With the development of chemical industry technology, non-toxic grade pipes can now be produced, which have the properties of general polyvinyl chloride and some excellent properties. Specifically, it has the advantages of corrosion resistance and flexibility, making it particularly suitable for water supply networks. Due to its non-conductive nature, it is not easily subjected to electrochemical reactions with acids, bases, and salts, making it difficult for them to corrode. Therefore, there is no need for an external anti-corrosion coating or inner lining. And its good flexibility overcomes the brittleness of plastic pipes in the past, allowing them to yield under load without breaking. I once conducted an experiment where a DN50mm UPVC pipe was placed on the ground and a Crown 3.0 car was driven on it. The pipe was only flattened, but not broken. Then we had the Dongfeng truck loaded with goods pass over the pipe, and the pipe only deformed without breaking. In addition, UPVC pipes have a smaller elastic modulus, which can reduce the amplitude of pressure impact and alleviate the impact force of water hammer. The inner wall of U-PVC pipe is smooth and has low resistance (the resistance coefficient of UPVC pipe is 0.009, while that of general galvanized pipe and cast iron pipe is 0.012-0.013), so it is obvious that the hydraulic conditions are good. When using pipes of the same diameter to transport the same liquid, the resistance of UPVC pipes is about 30% lower than that of galvanized pipes and cast iron pipes; When the head loss is the same, the water carrying capacity of UPVC pipes is more than 20% greater than that of cast iron pipes. Due to the smooth inner wall of the UPVC pipe, the liquid flowing inside will not scale, so its conveying capacity will not decrease with the increase of operating time. And this is precisely the insurmountable disadvantage of galvanized pipes and cast iron pipes. With the continuous deepening of reform and opening up, people's living standards are constantly improving, and the requirements for the quality of tap water are also increasing. In addition to ensuring that the produced water meets the standards for drinking water, the water supply industry must also ensure that the water transported through the pipeline network is qualified. People have strong reactions to phenomena such as "yellow water" and "black water" in tap water, and the main reason for the deterioration of water quality in the pipeline network is the corrosion of water supply pipelines, especially cold galvanized pipes. The coating on the inner wall of the pipes is unstable, and the pipes start to rust after a year or so of use, causing an iron smell and color in the water. The corrosion of galvanized pipes buried underground is even more serious. And UPVC pipes are corrosion-resistant. Not scaling, can inhibit bacterial growth, and is beneficial for protecting water quality from secondary pollution of pipelines. So UPVC pipes have a wide range of application prospects, especially for a large number of buried pipes in front of users' water meters.

In addition, UPVC pipes are also lightweight. The advantage of convenient transportation. The specific gravity of UPVC pipe is about 1.4 (the specific gravity of cast iron pipe is about 7.4), which is one-fifth of the weight of cast iron pipe. Using UPVC pipe can save 1/10-1/5 of transportation costs compared to cast iron pipe. It is very convenient for handling, loading and unloading construction. The construction environment for water supply pipelines is often harsh, and the construction site is muddy. It would be ideal to reduce the labor intensity of workers and shorten the construction period. And using UPVC pipes can achieve this ideal. UPVC pipes are lightweight and can be manually moved during installation, generally without the need for machinery. For example, a DN200 6m long UPVC pipe weighs about 55kg, while a cast iron pipe of the same diameter and length weighs 304kg. During installation, one person can carry the UPVC pipe, while the cast iron pipe requires three people or machinery to be lowered. This greatly reduces the labor intensity of workers and saves time and construction costs.

The connection methods of UPVC pipes include socket rubber ring connection, adhesive connection, and flange connection. These connection forms do not require digging a separate work pit and can be installed directly in the pipe trench. There is no need to use oil hemp or expanded cement to make joints. A manual hoist or a rubber ring can be used to insert the pipe socket end directly into the socket, and the depth of insertion can be determined by the marking at the end of the pipe.

· Product use

1. Tap water piping engineering (including indoor water supply and outdoor municipal water pipes), due to the advantages of UPVC plastic pipes such as acid and alkali resistance, corrosion resistance, non rusting, non scaling, water quality protection, and avoiding secondary pollution, has been widely promoted and applied in China and even globally as an ideal "green building material" for protecting human health in today's era of vigorously promoting the production of environmentally friendly products.

2. Water saving irrigation piping engineering, the use of UPVC drip irrigation system can save 50% -70% water compared to ordinary irrigation, while also saving fertilizer and pesticide usage, and increasing crop yield by 30% -80%. In today's China, where water resources are scarce and agricultural irrigation methods are outdated, this has great social benefits for promoting the development of water-saving agriculture production in China.

3. Building piping engineering.

4. UPVC plastic pipes have excellent insulation capabilities and are widely used as conduits for postal and telecommunications cables.

5. UPVC plastic pipes are acid and alkali resistant and corrosion-resistant, and are used as infusion piping in many chemical plants. Other applications include drilling engineering, pharmaceutical piping engineering, mineral salt water transportation piping engineering, electrical piping engineering, etc.
