PEX expansion fittings may be used in many places. Although PEX expansion fittings are inconspicuous, they play a very important role. When installing PEX expansion fittings, you must master certain methods. Today we will Everyone introduces the installation method and usage skills of PEX expansion fittings, you can learn about it.

PEX expansion fittings—styles and classifications of PEX expansion fittings

The commonly used expansion pipes are straight-through expansion pipes and fish-shaped expansion pipes. With the expansion and demand of the market, the styles of expansion pipes are becoming wider and wider, and their functions are more obvious and more powerful. Such as the special expansion pipe for ceiling gypsum board (aircraft type expansion pipe), and the multifunctional knotted expansion pipe for hollow wall hollow bricks. ZHENGPENG expansion tube size is M4-M16 diameter, length from 20mm to 160mm. Styles include straight expansion tube, fish-shaped expansion tube, tapered expansion tube, flange expansion tube, straight extension expansion tube, knotted expansion tube, American expansion Tube, tooth-type expansion tube, drive-in rapid expansion tube, double-fin fish-shaped expansion tube, nylon expansion tube, etc.

PEX expansion fittings—PEX expansion fittings installation method

For the installation of expansion pipes, some people say that it is very simple, but improper installation will affect the installation effect of the product. For the installation of expansion pipes, we should first understand the weight of the items to be installed and the hardness of the installation substrate, and then choose a suitable expansion pipe. If the installation items are heavy objects, large-size expansion pipes should be used. In addition, products of various lengths can be selected according to the installation base material (installation wall material), such as non-concrete, conversion bricks, porous bricks, etc. It is necessary to use a longer expansion tube to install the fixed object, and the focal length and focal distance determine the bearing capacity. When installing the expansion pipe, first understand the size of PEX expansion fittings. According to the size, drill the prefabricated hole (open the wall with a power tool). The hole size is equal to the outer diameter of the expansion pipe, and the length should be longer than the total length of the expansion pipe. 5mm-7mm. Then use the inner diameter to match the corresponding screws, such as the M8 expansion pipe, the inner diameter entrance is 6, the more you go in, the smaller, because of the base material, if it is installed in concrete, it can be firmly installed with a 5mm expansion pipe. Hard wall base materials such as quality bricks should be installed with 6mm self-tapping screws. The length of the screw is the total length of the expansion tube plus the thickness of the hanging clamp +5mm.

Drill the prefabricated holes with vertical balance at one time to avoid repeated drilling of the same hole multiple times. To clean the holes, the cleaning can be blown with wind, water, sweeping with wool, etc., to remove the residue left during drilling, so as to reduce the sliding of the expansion tube caused by dust and increase the friction. Avoid repeated use of holes and expansion tubes. The holes used multiple times will expand when the expansion tube is expanded. However, if the same hole is used multiple times, it is easy to cause sliding. Using the same expansion tube multiple times will cause expansion. The pipe is broken and deformed, which can easily cause the screws to deviate and the tightening force is not good.

PEX expansion fittings are very common, and the structure of PEX expansion fittings is very simple. Many people think that there are no skills to use PEX expansion fittings. In fact, it is not the case. If PEX expansion fittings are not used correctly, it may affect our progress Causes impact, so it is very necessary to understand the installation method and use skills of PEX expansion fittings.
