Fastening polypropylene pipes to the walls with special
When constructing communication systems, it becomes necessary to fix the pipelines to the side surfaces; therefore, various fasteners have to be used. Most often, prior to installation, special clips are installed, the price of which is low.
The holding parts of this type are great when laying the heating and plumbing.
Advantages of fasteners
A similar mounting for polypropylene pipes can be installed on the surface of concrete, brick, drywall and wood. For some systems, double clips are specially produced, allowing to fix two lines parallel to each other at once.
The following are the basic advantages of the elements:
- A simple installation process makes it possible to facilitate the installation work carried out when connecting communications. Fixing to surfaces is carried out with the help of screws.
- Reliable fixation allows you to avoid distortions of pipelines and their attacks, if, of course, during the installation the distance between fasteners was correctly chosen. The step depends on the operating conditions.
- The ability to use in a wide range of temperatures provides the ability to mount pipelines of various communication networks.
- Thanks to an aesthetically appealing look, it is quite possible to use these elements when carrying out systems without subsequently hiding the main components.
Note! In addition, a special strap can be supplied complete with fasteners to protect the clamped pipe from unintentional jumping out of the fixed support.
Self install
Before proceeding with the installation of their own hands, novice masters are invited to consider this operation in detail so that after installation work there is no difficulty. The main problems, as a rule, appear when choosing the wrong step between the parts and low-quality fixing to the surface. Pipes just fall out of support.
Step between elements
Polypropylene, like all other plastics, is prone to expansion and contraction when temperature changes, so the distance between the anchors of polypropylene pipes should be chosen taking into account this factor. Below is a table that will help determine the choice of step. The main emphasis in it is on the temperature regime.
| Pipe diameter in millimeters | Distance in centimeters at a certain temperature | |||||
| +70 | +60 | +50 | +40 | +thirty | +20 | |
| 110 | 140 | 160 | 165 | 175 | 180 | 185 |
| 90 | 125 | 145 | 150 | 155 | 165 | 165 |
| 75 | 115 | 130 | 135 | 145 | 150 | 155 |
| 50 | 90 | 105 | 110 | 115 | 120 | 125 |
| 40 | 85 | 95 | 100 | 105 | 110 | 110 |
| 32 | 75 | 85 | 90 | 95 | 95 | 100 |
| 25 | 70 | 75 | 80 | 85 | 85 | 85 |
| 20 | 60 | 65 | 70 | 70 | 75 | 80 |
| sixteen | 55 | 65 | 65 | 70 | 70 | 75 |
Attention! The table below provides an opportunity for beginners to understand what the distance between polypropylene pipe and wall fastening is considered to be the most optimal.
Installation process
After reviewing the theoretical information, the instructions for directly installing the parts in place should be carefully studied. In the presence of stone walls, dowels should be used.
If the side surfaces are made of wood, then you only need screws.
- First of all, fasteners are fixed along the edges of the wall so that it is possible to align. In this case, the screw is inserted into the central part of the plastic part, after which it is screwed in with a screwdriver or a cross-head screwdriver.
- After the installation of the extreme elements took place, the lace is compulsorily tensioned, which will make it possible to expose the rest of the fasteners. If necessary, you can use the level to repel the line from one part to another.
- Directly along the stretched rope, the remaining elements are installed.. However, before this, the installation step must be defined. After that with the help of a tape measure attachment points are marked.
- At the last stage, the pipes are installed and neatly inserted into the finished fasteners. In the presence of fasteners with an additional latch, the process of closing elements is carried out.
Note! Products made of polypropylene, which have a reinforcing layer of aluminum foil, have a much smaller linear expansion, so for them the step can be slightly increased.
additional information
Installation work on the installation of polypropylene pipes in our country is governed by paragraphs of GOST 52134-2003, where there is complete information on pressure products from thermoplastics. The basic purpose of installing such products is to ensure operating conditions under which the temperature and pressure of the transported medium will not cause internal stresses that could compromise the integrity of the system.
The most important task is to compensate for linear expansion, from which the fixed supports, which react autonomously to temperature fluctuations, can save. As the sliding fasteners are double or single clips, corresponding to the diameter of the pipeline.
The provisions of SP 40-101-96 do not allow the fastening of polypropylene products in a rigid position. It is for this reason that the fixed supports are made on the basis of sliding analogs, which prevent axial movement of the laid pipeline.
In conclusion
After studying the presented information, even a beginner can correctly fix pipes made of polypropylene, however, it is recommended to watch the video in this article as a visual aid (learn here how to solder polypropylene pipes).
In this case, it will be much better to assimilate the topic being analyzed, and then to do the work as well as possible. Fastening on clips to avoid difficulties that sometimes arise after installing clamps.
