Can

PE pipes be used for indoor drainage? This is a common question when many families decorate or renovate old houses - after all, PE pipes (polyethylene pipes) are more used in outdoor scenes such as municipal water supply and drainage, farmland irrigation, etc., and are less used indoors, which inevitably makes people hesitate. In fact, as long as the characteristics of PE pipes are sorted out with the core requirements of indoor drainage, the answer will be very clear.

First, a simple understanding of PE pipes: it is made of food-grade polyethylene as raw materials. The most outstanding features are that the inner wall is super smooth, flexible, corrosion-resistant, and light weight and easy installation. These characteristics just match the "rigid requirements" of indoor drainage.

What are the core requirements of indoor drainage? Nothing more than "no blockage, no leakage, safety and durability" - we compare the performance of PE pipes one by one:

1. Anti-clogging: Natural solution to drainage pain points

The most troublesome thing about indoor drainage is oil pollution and hair blockage, while the roughness of the inner wall of the PE pipe is only 0.0015mm (much lower than the 0.006mm of the PVC pipe), the water flow resistance is extremely small, and impurities can hardly adhere; coupled with flexibility allows the pipe to bend naturally, and will not form a "dead angle of water accumulation", even if there is a small amount of debris can be washed away by the water flow. For example, kitchen drainage, the smooth inner wall of the PE pipe can effectively reduce oil pollution hanging on the wall, which is less likely to be blocked than traditional pipes.

2. Temperature resistance: It is no problem to meet the daily household

Some people are worried that the PE pipe is afraid of hot water? In fact, the long-term use temperature range of PE pipes is -60 ° C to 60 ° C, while the daily drainage temperature of households - kitchen dishwashing water 40-50 ° C, bathroom bath water 38-42 ° C, are within the safe range. Even if you occasionally pour some warm water (such as freshly cooked soup), it will not damage the pipeline in a short time; as long as you do not come into contact with liquids over 60 ° C for a long time (such as directly pouring boiling water), there is no need to worry about aging.

3. Connection reliability: hot melt seamless, no leakage at all

Indoor drainage is the most avoid "water leakage", and the connection method of PE pipes is hot melt butt/socket - by heating the pipe port, the plastic is melted and fused into a whole. After cooling, there are no gaps, no glue or sealing rings and other easy-to-age parts, and the risk of leakage is almost zero. Compared with the "glue bonding" of PVC pipes (glue will age and degummed over time), the connection of PE pipes is more stable and will not leak for decades.

4. Environmental protection: indoor use is more secure

PE pipes are food-grade materials (many water dispenser pipes are PE pipes), do not contain formaldehyde, heavy metals and other harmful substances, no odor after installation, fully meet the indoor environmental safety requirements. For families with the elderly and children, this is more reassuring than some "odor" plastic pipes.

Of course, there are also "precautions" for indoor drainage of PE pipes to avoid stepping on pits:

- Choose the right grade: PE100 grade is preferred (higher density and greater strength), which is more suitable for indoor than PE80 grade - after all, indoor pipes have to withstand long-term water flow pressure and daily collisions.

- Construction specifications: the temperature should be controlled at about 210 ° C during hot melt (too high charred, too low sticky); the slope of the pipeline should meet the requirements of 1% -3% to ensure smooth water flow; when buried or concealed, use thermal insulation cotton or casing protection to avoid sharp collision.

- Avoid long-term high temperature: Although temperature resistance, do not let PE pipes contact liquids over 60 ° C for a long time, such as directly pouring freshly boiled water, which will accelerate aging.

see this, the conclusion is very clear: PE pipe can be used for indoor drainage. It not only meets the core needs of "no blockage, no leakage, and safety", but also is lighter and more environmentally friendly than traditional pipes. As long as the right grade is selected and the construction is standardized, PE pipe will be the "cost-effective choice" for indoor drainage - easy-to-use pipes are not necessarily "commonly used", but "suitable".
