If it is necessary to lay communications in public and residential buildings, an important point is the fastening to the wall of the pipe. Depending on which products are used, different types of fasteners can be used. The latter differ in design, material and method of fixing in the wall.
The mounting method will depend not only on the pipes themselves, but also on the type of wall. The main types of pipes that are used in laying communications can be divided into the following categories: drainpipes and polypropylene pipes. The latter option is used for laying sewerage and plumbing systems. They can vary in diameter, and clips and clamps are used for fixation.
If we are talking about downpipes, then they are intended for the installation of drainage systems. They are made of metal or plastic, and fixation is carried out using special clamps. Metal pipes are used for the installation of water supply systems, gas pipelines and sewerage. You can use clamps to fasten them.
Preparation of tools andmaterials
If you will be fixing the downpipe to the wall, then you need to stock up on some tools and materials. This is:
- hammer;
- Phillips screwdriver;
- roulette;
- marker;
- drill;
- knife or scissors for cutting pipes;
- level.
Use clamps
If it is necessary to fasten the pipe to the wall, then you can use different clamps for this, which can be plastic or metal. The first variety is used for the installation of sewers, drainage systems and polypropylene pipes. These elements are a support with a dowel, which is installed in the wall. To fix the pipe, a semicircle is used, which is connected to the support-screw element.
Fastening to the pipe wall can be done using metal clamps, which are designed for pipes of the same material. Sometimes they are used for mounting systems made of plastic. These elements are a support with an impact anchor or dowel for wall mounting. Pipes are fixed with a semicircle on screw connections. On the outer diameter of the pipe inside the clamp there is a rubber ring, which is used to reduce noise and dampen vibration.
Use staples
Fastening to the wall of the pipe can be carried out not only according to the technology described above, but also with the help of brackets. If the pipeswill be used to equip the plumbing system, then this technique can be used. This element is a nylon support, which is fixed with dowels to the wall. A pipe will have to be snapped into it.
When laying the system, the brackets are distributed along the axis of the water pipe, and the distance between them should be 50 cm. To install them, markings are first applied to the wall, along which holes are made. After the brackets are installed in their places, and the pipe is laid on them. If we are talking about a sewer pipe, then metal or plastic clamps can be used for it.
More about fixing downpipes
Clamps for pipes are used according to a certain technique. If you purchase plastic pipes, then suitable clamps should come with them. To install them on the wall, it is also necessary to make markings first, given that the first hole should be placed under the water collector. The distance between the remaining fasteners should be 50 cm or less. It is important to calculate the pitch between the fasteners so that there are two clamps per linear meter of the pipe.
For gutters, you must use brackets that are attached to the front board or rafters with self-tapping screws. When marking, it is necessary to take into account the slope of the drain, it should be 3 mm per linear meter. Some home craftsmen think about what to choose - staples or pipe clamps. Staples are a cheaper method, but not asreliable. Therefore, quite often, metal pipes are fixed with clamps, which consist of a support installed in the wall using a dowel or anchor.
Using clips
When choosing a fastener for plastic pipes, you may prefer clips that have high quality heat resistance and are resistant to mechanical stress. Among the technical characteristics, attention should be paid to the diameter, which should be equal to this indicator of the polypropylene pipe. The correct installation of fasteners will affect the life of the finished communication system.
If the clips are set too far apart, a kink may occur at the supports. When installing a communication system with parallel pipes, a double clip should be used. It is important to know about the dependence of the distance between the clips on temperature and pipe diameter. Thus, if the pipe diameter is 16 mm and the temperature is 20 °C, then the distance between the clips should be 75 cm. With the same pipe diameter and a temperature of 80 °C, the distance should be reduced to 55 cm. When the diameter increases to 32 mm, and the temperature remains at 20 ° C, then the distance between the clips should be made equal to 100 cm. The same pipe diameter and a temperature of 70 ° C require a distance of 75 cm. With a pipe diameter of 110 mm and a temperature of 40 ° C the distance between the clips should be 175 cm, while if, with the same diameter, the temperature increases to 70°С, the distance should be made equal to 140 cm. It is also important to remember that the bracket for attaching the pipe to the wall must be selected taking into account the outer diameter of the installed system element.
Expert advice on using clamps
Fixation of polypropylene pipes with clamps is carried out in cases where it is necessary to mount pipes of impressive diameter and heavy weight. With the help of these elements, the pipe will be securely held, and strong vibrations will be leveled. The bracket for attaching the pipe to the wall is supplied with a clamp, this fixing provides a rigid grip, which can be achieved by tightly tightening the clamp around the pipe. If the fastening should be floating, then between the clamp and the pipe, free space should be left for the movement of the element. The mobility of the fastener guarantees the possibility of expansion of the material with temperature fluctuations.
Conclusion
Before installing the pipe on the fixture in the wall, it is necessary to connect the elements to each other using polyfusion or butt welding, which is sometimes replaced by the electrofitting method. Holes for dowel-nails in the wall are made with a drill.
