Vinyl plastic tube - features and scope
Today, the building materials market is simply replete with various types of plastic pipes, among which vinyl-plastic pipes occupy a worthy place.
In this article we will take a closer look at their features, types and scope.
What is viniplast
In fact, viniplast is a modified, well-known perchlorovinyl, to which are added:
- Stabilizers;
- Colorants;
- Lubricants;
- Perchlorvinyl resins.
As a result of all these additives, the material is more resistant to high temperatures, corrosive environments and exposure to ultraviolet radiation. I must say that vinyl plastic is also called unplasticized polyvinyl chloride, since it contains a low content of plasticizers - no more than 10 percent. Due to this, the pipes are more rigid.
The same polyvinyl chloride, but with a high content of plasticizers (up to 50 percent) is used in the manufacture of plastic decorative panels, vinyl leatherette, which is commonly used for upholstering furniture, and other certain products.
It should be noted that the low content of plasticizer does not make vinyl plastic pipes fragile at all. As an example of bending strength, we can cite spinning made of vinyl plastic and corrugated pipes.
Features of vinyl plastic pipes
Merits
Technical characteristics of the vinyl plastic pipe are very attractive.
In particular, the following advantages can be identified:
- The possibility of operating the pipeline at temperatures from -10 degrees Celsius to +50.
- The service life can be up to fifty years.
- Low weight.
- Resistance to chemicals.
- Easy installation.
- Low price.
- The tightness of the joints, which is achieved due to the presence of sockets with rubber sealing rings or welding.
- Resistance to corrosion and decay, which increases the service life of products.
- Relative fire resistance, so that corrugated tubes can be used for laying electrical networks.
- Environmentally friendly - the material is not harmful to human health.
disadvantages
Of the serious shortcomings of vinyl plastic, only brittleness at low temperatures can be distinguished. This somewhat limits the external use of such pipelines.
Application area
Viniplast was especially widely used in the construction of technological pipelines, which is explained by its resistance to such chemicals as:
- Acids;
- Alkalis;
- Solvents;
- Salt
However, besides technological pipelines, it is also often used for the following purposes:
| When laying power grids | As cable channels |
| When building ventilation systems | As exhaust shafts and ducts |
| When arranging sewers | Both in gravity and pressure systems |
| When the device is cold water | As an internal plumbing |
Kinds
Since the scope of the vinyl pipe is quite extensive, they are of different types.
In particular, products may vary:
- Diameter;
- The number of layers - are single-layer and double-layer;
- Coloring;
- Stiffness;
- Surface - can be smooth or corrugated.
Tip! In private housing construction, corrugated vinyl plastic is often used for outdoor sewage systems. However, according to building codes, smooth orange pipes should be used for outdoor sewage.
When choosing pipes, it must be borne in mind that the requirements for plumbing and free-flow sewerage are different requirements. So according to GOST 51613-2000 pressure pipes should have the following characteristics:
| Maximum elongation when heated | Not more than 5% |
| Maximum elongation at break | 25% |
| Heat resistance | The material should not lose its hardness and strength at temperatures up to 78 degrees C |
| Resistance with a pressure inside the system of 35 MPa and the temperature of the liquid - 20 degrees Celsius | At least 100 hours |
When constructing free-flow sewers, there are no requirements for the strength of the pipeline.
The only products should:
- To maintain the pressure declared by the manufacturer on the walls of the pipes and the specified maximum temperature.
- Fit standard sizes;
- Possess resistance to moisture and chemical elements.
Installation
The instruction for installation of the pipeline depends largely on its type. For example, installation of water supply will be performed using a low-temperature soldering iron. The process looks the same as when working with polypropylene pipes.
The assembly of sewage systems, as already mentioned above, is performed by the socket method. In this case, reliable sealing of the joints is ensured with the help of silicone sealant. In general, any type of installation can be done by hand with every home artist.
Tip! To connect the vinyl plastic with other materials of the pipeline, you should use special couplings.
At installation of the full-fledged pipeline, with branches, torsions, etc., regardless of its type, use various fittings. Their diameter must correspond to the diameter of the pipeline.
In general, it can be said that viniplast does not differ in any particular features of pipeline installation.
Conclusion
Vinyl plastic pipes surpass polypropylene analogues in some indicators, as well as other plastic pipes. Therefore, in many areas of construction, they are widely spread. In particular, these products enjoy a certain popularity in private housing.
