In our lives, PVC drainage pipes are like "invisible stewards" - hidden in the wall, buried in the ground, silently draining sewage and rainwater away, but few people really understand it. From the bathroom at home to the rainwater well in the community, from the waste water pipe of the factory to the irrigation canal in the countryside, PVC drainage pipes are everywhere. Today we will "take it apart" and say: what types are there? What are the "advantages"? Where is it suitable for use?

Let's talk about the classification first - the types of PVC drainage pipes are actually very easy to understand, and they are mainly divided into two categories: the most common is U-PVC pipes (hard polyvinyl chloride pipes), which do not add plasticizers, have strong rigidity and high hardness, and are the "main force" of home decoration and municipal engineering; the other type is flexible PVC pipes, which add a small amount of plasticizers and can be slightly bent, suitable for scenarios that require buffer displacement (such as pipe bends, equipment connection pipes). If divided by purpose, they can also be divided into building drainage pipes (home kitchens, toilets), municipal engineering pipes (residential rain water pipe networks, urban sewage trunk lines), and industrial pipes (factory acid and alkali wastewater discharge). The wall thickness and strength of each type will be adjusted according to the scene.

Let's talk about the core characteristics again - the PVC drain pipe can be "hot" for so many years, relying on these "hard strengths": First, it is corrosion-resistant and corrosion-resistant, unlike metal pipes that will be corroded by acid and alkali in sewage and detergents, and will not rust and leak for ten or twenty years; second, it is pressure-resistant and collision-resistant. The wall thickness of high-quality pipes is uniform. Buried in the ground can withstand vehicle rolling and soil pressure. Buried in the main road in municipal engineering is no problem; third, the drainage is smooth, the inner wall is smooth like ceramics, and the sewage flow will not hang on the wall, which is 80% less blocked than cast iron pipes; fourth, it is light and easy to install. A pipe is only a few kilograms, and workers can move it with one hand. It is firmly glued with special glue. Without welding, the decorator can install a set of pipes in half a day; fifth, it has PVC pipes with anti-aging stabilizers can be used normally for 20-30 years, and there is basically no need to change them once installed at home.

Finally, the applicable scene - choose the right scene to not waste: home decoration priority U-PVC pipe, kitchen sink, bathroom toilet, balcony washing machine drainage can be used, drainage fast and no odor; municipal engineering should use thickened municipal-grade PVC pipe, community rainwater collection, urban sewage trunk line rely on it to carry the pressure; factory discharge acid and alkali wastewater? Choose industrial PVC pipe, corrosion resistance is stronger; rural irrigation and drainage is also suitable, not afraid of microbial corrosion in the soil, much more durable than metal pipe.

There are other tips for choosing PVC pipe: look at the wall thickness (the thicker the stronger), look at the gloss (the inner wall is smooth and free of impurities), smell the smell (no pungent smell is a good material). In fact, PVC drainage pipes are not so complicated. If you understand the classification, characteristics and scenarios, you can choose the right one whether it is for your own decoration or engineering.

In the end, PVC drainage pipes can become the "top flow" of the drainage industry because it is cost-effective and adaptable - hidden in an invisible place, but solves the most critical "drainage problem". Next time you decorate or do a project, you might as well take a look at it more, that's right.
