When the device of any pipeline it is important to secure it. From the quality of the operation is directly related to the reliability of any future system. When attaching the steel pipes to the wall need to follow the rules of this work, choose a high-quality fixtures, all pre-calculated circuit design. This will create a robust communications system that will last long.
types of fasteners
Steel pipes are fixed to the wall with the help of several types of attachments:
- Special staples.
- Brackets.
- Clamps required configuration.
All the elements are selected with consideration of the outer diameter of the installed system requirements the appearance of lines, and possibly the frequency of mounting and dismantling joints, flange connections and all design.
it is impossible to build a pipeline without reliable fastenings. First you need to select the appropriate item for your conditions and perform the assembly of the system correctly.
metal clamps
The design is the same for the large and the little collars, the set includes:
| semirings | Can reliably clamp the pipe. Two half rings are joined together by bolts, they allow you to adjust the compression force. |
| rubber gaskets | Wear on the half-rings serve to clamp tightly compressed the pipe, reduce vibration experienced when pumping liquid. |
| stud fastening | Welded to the semiring thereon thread diameter of 8-10 mm, is used for pipe installation. The length can be different 80-180 mm. Acquiring clamps need to calculate the required length of the element based on the construction of the pipeline. |
Plus these products in the long life and reliability, minus - uncomfortable to hide from the eyes indoors.
Clips
Such elements are known a lot of people use them to assemble in generally thin lines differ in that:
- In the production of polystyrene is used - robust and durable material, which serves long withstands external influences.
- The articles may be single or double, design speeds gasket system.
- Can collect the required design of several elements for the laying of different branches (for example, the pipings of hot and cold water) due to the grooves on the products.
- Special pipe clips are able to retain a diameter of 15-50 mm.
- With the aid of screws or dowels, which simplifies installation.
Clips for pipes
Similar to the clips, these products have their own characteristics:
- The main difference - the closed fastener with its help you fix the pipe, rather than just its latches. This increases reliability, which is important on systems arranged vertically.
- Produce 2 kinds of products, the first clamping screw holds a holding pipe and fixes the fastening in the wall. In the second embodiment, the flip part is separated from the screw and, mounted for dismantling steel pipe is required to unscrew the screws.
- There are products whose plugs are purchased separately, they are attracted by its cheapness.
They make it possible to reliably fix the pipeline laid.
staples
Made of galvanized steel, obtained thanks to this long-lasting products. They are used in places where important life and reliability. Pay attention to the thickness of the bracket, thick metal capable of withstanding heavy loads:
- Classical design - arched bracket with two legs, with two of its sides are made lugs into place. The most important thing - to choose a suitable diameter products.
- Second option - a bracket-shaped products P, it strips 2 are joined together and have one opening for installing products. They are well suited for mounted water pipes, corrugated and so on. May clamp the pipe diameter of 10-120 mm.
- Staples are used with one foot at low loads.
The products can be used in conjunction with a rubber gasket for fixing and reliable reduce possible vibrations.
The choice of fastening of pipelines
It is easier and cheaper to fix the pipe, non-collapsible brackets. Clamps with rubber gasket installed in them will cost a bit more expensive, but it is convenient to put and in the future can be required to dismantle part of the pipeline, for example, to replace the steel pipe, and then re-assemble the system. Brackets are used infrequently, generally at the device of complex pipelines.
Putting steel structures, do not forget that when they are filled with water, it weighs a lot. Therefore it is necessary to choose the device that will be able to withstand the total weight of the line. It is important to choose the right element rigidly connecting it to the wall, it can be an anchor or anchor. It is necessary to take into account the total weight of the system and the fluid moving through it, and then divide the weight by the number of attachment points. The result is a weight acting on one anchor (anchor).
It is necessary to take into account the quality of the walls bearing material. During installation of pipeline steel pipes to walls of concrete, reliability problems would arise. When attaching the structure to the walls built of wood, aerocrete and similar materials with low shear stress or separation, have to buy more powerful fastening. In such a material it is desirable to do more attachment points system for secure fastening.
Tips for installation of steel pipes
Pipeline installation is carried out by performing several mandatory rules:
- Vertical installation would cut line is performed using longer fasteners compared with installation in the horizontal position.
- When installing the steel pipe of small thickness need to do more fixing points than when installing large articles.
- At the bend in bottom of the tube clamped vertically in a field where it becomes horizontal, it is necessary to fix the additional clamp. It is unacceptable that the deformation load of the vertical branch system, passed directly to "lounger".
- When installing the riser does not exceed 3m, mount can be left out. If the system get the length of 3 m, the center of the floor to install mount.
- Pipes extending to the radiators, should be carried out by installing fasteners through 1.5m.
Choose the appropriate spacing between individual fasteners in horizontal allows a simple table:
Cross-section mm |
The maximum distance between the supports of steel pipe in meters | |
| uninsulated | Isolated |
|
| 15 | 2.5 | 1.5 |
| 20 | 3 | 2 |
| 25 | 3.5 | 2 |
| 32 | 4 | 2.5 |
| 40 | 4.5 | 3 |
| 50 | 5 | 3 |
| 70.8 | 6 | 4 |
| 100 | 6 | 4.5 |
| 125 | 7 | 5 |
| 150 | 8 | 6 |
These data allow to determine the required distance between the individual fastening elements for pipes of different diameters.
Any system must be installed, taking into account temperature. When heated air or high-temperature coolant, metal expands inevitably, this does not succeed completely eliminate, placing reinforced pipes. The assembly of the heating system to perform better by a sliding connection or plastic brackets.
The desired space between the points of support according to SNIP
A suitable distance between the points of support of the pipeline is an important characteristic for operation of the system. The point where the installed mounting, allow distribute the available load, minimize the possible voltage. When laying the heating mains is centrally distribute the thermal load.
The characteristics are listed in Tables snip contain requirements for acceptable free space between the fixed supports, with the destination system. These data are required to have in the tables, which greatly simplify the calculation system. Remember that the data is not recommended in the table, and a specific distance corresponding SNP at what distance, which and how many fasteners must be installed.
The selection of suitable holders is directly dependent on the characteristics of the mounted system and the level of future pressures on used items. Free pipe arrangement required where possible effect of expansion under heat. Suitable attachment allows you to expand the elements to move freely when heated, but it is good to keep the system on a wall surface.
