Positive aspects of the use of XLPE pipes
Cross-linked polyethylene pipe elements are widely used by professionals to install low-temperature heating for residential and other premises. Low-temperature systems are systems whose total operating temperature does not exceed 80 ° C. This type of pipe is also suitable for use in cold and drinking water conduits. In working with this material, a tool is required for the assembly of cross-linked polyethylene.
Plumbing fixtures made of cross-linked polyethylene have a number of positive qualities and advantages in comparison with pipeline elements made of other materials.
- The most important property of a pipe made of cross-linked polyethylene professionals is the so-called "memory".This is manifested in the ability to restore the original shape after mechanical impact. This quality of the material helps to install the equipment in difficult conditions.
- Pipe products made of cross-linked polyethylene have a high coefficient of resistance to mechanical stress.
- Plumbing fixtures of the presented material have cushioning properties when providing various external influences on it.
- Resistance to temperature effects. Elements of a pipeline made of cross-linked polyethylene can be used in heating systems with an operating temperature of not more than 80 ° C.If necessary, short-term heating to a temperature of 95 ° C is allowed.
- High resistance to the effects of various chemical elements.
- The low weight of XLPE pipes greatly facilitates their installation and transportation. In view of this quality, the transportation of pipe products can be carried out in large volumes in the form of bays.
- Ease of installation, for the implementation of which requires a tool for mounting cross-linked polyethylene.
Specifics of installation of water supply systems using cross-linked polyethylene(
) fittings. The assembly of pipe systems is performed not by soldering( as in the case of polypropylene) and not by gluing( as in the case of PVC), but by connecting the pipeline components with various fittings. For the installation of water pipelines with the use of pipes made of cross-linked polyethylene, such tools are needed.
- Various fittings for connecting individual sectors of pipe products. Fittings are compression and pressing type.
- Sleeve or crimp nuts. To connect the pipe to the fittings.
- Hydraulic or manual press. To connect the cutter sleeves and fittings.
- Pipe cutter or pruner. Tools that are needed to divide the tap fitting into the required pieces.
- Spanners for tightening the threaded joints.
Installation of XLPE pipes using various
fittings. Connection using compression fitting. To install this type of connection, you need a tool for mounting a cross-linked polyethylene: crimping nut, split ring, fitting union, spanner. The work is carried out in the following order:
- The crimp nut is put on the pipe.
- Then, on the end of the tubular product, a split ring is placed, which should be one millimeter from the edge.
- Then the tube is pressed against the stop of the fitting as far as it will go.
- The crimping nut is tightened to the stop with a wrench.
This type of connection is easy to use and the need for a minimum set of tools. Also, this type of installation reserves the possibility of dismounting the connection without losing the working capacity of the material.
Connection with a non-pressure fitting. This type of bonding of cross-linked polyethylene pipes is very reliable and durable. The disadvantages of this type of connection are the impossibility of disconnecting materials and the need for a press tool to carry out work. To assemble this type of fixing parts of the water supply valves, such a tool is required for mounting cross-linked polyethylene: clamping threaded sleeve, expander, non-press fitting, hydraulic or manual press.
- A clamping nut is put on the pipe.
- Then the expander is placed on the end of the tubular product.
- Then it is necessary to move the handle of the expander and fix it for a short time.
- Then insert the end of the pipe into the fitting of the fitting.
- The threaded sleeve is pressed into the fitting of the fitting.
Thus, the article outlined the main characteristics and specific features of pipes made of cross-linked polyethylene. Also, the methods of connecting pipes and the tools necessary for this were listed.
