With the development of the economy and the needs of society, the plastic pipe industry is developing faster and faster, but how much do we know about PVC-U drain pipes, PVC water pipes, PE water pipes, HDPE bellows and other water pipe fittings? In fact, there are a lot of plumbing fittings, and each fitting has a different role to help us complete the waterway reconstruction project, then let's take a look.


Plastic pipes - what are the specifics of water pipes?


First, direct - plastic pipe fittings

Also known as straight through, casing, pipe joints. Pay attention to the size of the water pipe when using it. When the pipe is not long enough, it can be used as an accessory connecting the two pipes to extend the plastic pipe.


Second, elbow - plastic pipe fittings

It is used for turning water pipes. Since the water pipes themselves are straight and cannot be bent, if the direction of the water pipes is to be changed, it can only be realized by elbows, mainly including 45° elbows and 90° elbows.


Third, inner wire and outer wire - plastic pipe fittings

It is used when connecting faucets, water meters and other types of water pipes. It is usually used together. The main components used in home decoration are the inner wire pieces.


Fourth, three links - plastic pipe fittings

Divided into three-way and three-way three-way, it is used to connect water pipes in three different directions. It needs to be used when a waterway is drawn from a water pipe.


 Fifth, size head - plastic pipe fittings

It is used to connect two pipes with different pipe diameters. Direct, elbow and tee have different sizes.


Sixth, plugging - plastic pipe fittings

After the water pipe is installed, it is used to temporarily close the water outlet. It will be removed when the faucet is installed. When using the plug, pay attention to the size and the corresponding pipe fittings.


 Seventh, winding bends - plastic pipe fittings

Also called the bridge, when the two water pipes meet in the same plane without docking, in order to ensure the normal use of the water pipe, we use the transition of the winding curve, just like the arch bridge, avoiding the direct intersection of the water pipes through the plane avoidance.


 Eighth, the valve - plastic pipe fittings

The function is to open and close the water flow; the function of the pipe clamp is to fix the position of the water pipe and prevent the water pipe from shifting.


 Ninth, S-bend and P-bend--plastic pipe fittings

Generally used for the water bucket and the water pipe link, both have the function of deodorization, the S curve is generally used for the misalignment link, and the P curve is the deodorization link. Its role is to prevent blockage and deodorization.


Water pipe fittings purchase method:

First, choose matching

When purchasing water pipe fittings, it is necessary to select the fittings that are compatible with the pipe, and it is best to choose the matching pipe fittings of the same brand.


Second, smell

You can use your nose to smell whether the plumbing fittings contain irritating odors, and good quality fittings should have no odor.


Third, look at the appearance

When purchasing pipe fittings, pay attention to observe whether the color and gloss are uniform, whether the wall thickness of the pipe fitting is uniform, and whether the pipe wall is smooth or not; the pipe fitting with threaded wire should also pay attention to whether the distribution of the thread is uniform.


Fourth, test performance

When purchasing water pipe fittings, carefully read the product manual and certificate to understand the performance indicators of the product. The safest way is to go shopping in the large formal building materials market.


Fifth, choose a brand

The selection of pipe fittings of well-known brands is relatively quality-assured, not only in terms of product size and design, but also more secure in use.
