In the building drainage system, PVC drainage pipes have become "frequent customers" in every household and engineering construction due to their cost-effective, corrosion-resistant and easy installation characteristics, and the 110 specification is the most commonly used "main model". Many people are confused about its specific parameters, where it can be used, and what to pay attention to when installing. Today we will take this "drainage expert" apart to chat clearly.

Let's talk about the size you are most concerned about first - the 110 specification PVC drainage pipe. "110" refers to the outer diameter of the pipe 110 mm, which is a common nominal diameter marking method in the industry, which is convenient for everyone to quickly identify. In terms of wall thickness, it is divided into different grades: light pipe wall thickness is about 3.2 mm, suitable for daily drainage of ordinary houses; medium pipe wall thickness is 4.0 mm, which is the "standard" of residential and commercial buildings; heavy pipe wall thickness is 5.3 mm, which is mainly high strength and is mostly used in municipal engineering or high pressure scenes. In terms of length, the standard pipe is generally 4 meters/root. Although shorter or longer sizes can be customized, customization will increase transportation costs. Unless there are special needs, it is recommended to choose the standard length first.

Then look at what it can "do" - the 110-size PVC drain pipe covers almost 80% of the drainage scenarios: such as toilet drainage in the house (the toilet has a large instantaneous displacement, and the 110mm pipe diameter can just "catch"), laundry pool drainage in the balcony; shopping mall public toilets in commercial buildings, kitchen drainage in the back of restaurants (such places use water frequently, and large pipe diameters can avoid blockage); residential rain pipes in municipal engineering, street drain connecting pipes (municipal high-intensity requirements require heavy-duty 110 pipes); even basement sump drainage, air conditioning condensate main pipes, as long as the drainage flow matches, it can be competent.

Finally, talk about the "key points of avoiding pits" for installation. If this step is not done well, there will be problems with the pipes that are easy to use: first check the pipes - be sure to check whether the pipes are cracked or sunken before installation, and whether the pipe fittings (elbows, tee) are damaged. Don't use defective products to make up the number; then stick the interface - PVC pipes are commonly used for "socket bonding". First wipe the interface of the pipes and pipe fittings clean, evenly apply PVC special glue, rotate 1/4 turn after quick insertion, keep it still for 30 seconds, and don't touch the glue before it dries; then control the slope - the slope of the drainage pipe directly affects the smoothness. The standard slope of 110 pipes is 1.5% (1.5 cm per meter). For example, for a 3-meter-long pipe, the height difference between the two ends is 4.5 cm. The slope is too high Small is easy to accumulate water and stink, and too large will increase the difficulty of construction; and then fix it well - when fixing with a pipe clamp, the horizontal pipe should be every 1.5 meters and the riser pipe every 2 meters. The pipe clamp should be close to the wall and do not let the pipe dangle; finally do acceptance - be sure to do a "water closure test" after installation: block the two ends of the pipe, fill the water to the specified height, and see if there is any leakage after 24 hours. If there is no problem, bury the soil or seal the groove.

In fact, 110 specifications of PVC drain pipe is not so "complicated", figure out the size of the right level, according to the scene with the right place, the installation of the details in place, it can safely help you "out of trouble". Whether it is their own decoration or help others do the project, remember these points, you can less stepping on the pit, more worry.
