Reinforced plastic pipes: types, devices, plus

To select a reinforced plastic pipe is important to understand what functions they will perform. Will part of the water pipe with cold or hot water, or perform the heating operation circuit.

Types of reinforced plastic pipes

For communications devices assign markings. Each of them reminds the buyer of functionality:

RTD - cold water supply and heating apparatus with the highest level of safety.

PPH - ventilation device, cold water.

PPR - universal model. This PVC products for the heating device for hot and cold water. Needed in the economy, in backyards, garages and buildings.

An alternative to traditional metal pipe is reinforced propylene which is different qualities:

• Strength
• Temperature resistance
• Resistance to the destructive influence of chemicals.

An inexpensive option - a single-layer type. Provide increased strength multilayer embodiments, having from three to 5 layers. Durability is achieved by alternative materials. Thanks to aluminum, it increases, but the weight does not become the cause of complicating the structure, as the invoice is easy.

Strength can be achieved through other material - fiberglass, which is applied to the inside surface. The multilayer polypropylene product is present adhesive area, without which the layers would not be kept. Due to the different markings to distinguish them easily.

When viewed in the context of the design is similar to the sandwiches, which are very clearly visible identity of the upper and lower layers, and in the middle layers of fiberglass or aluminum is clearly visible. According to the composition layout are:

• PPR-FB-PPR - form a middle layer of glass fibers;
• PPR-AL-PPR or PPR-AL-PEX - view middle aluminum layer.

Strengthening organized in five ways:

1. Thermostrengthening aluminum sheets with the appearance of the texture of hand. Solid aluminum sheets are interconnected at a distance of about one millimeter;
2. Thermostrengthening perforated aluminum sheetWhen the outside of the communications devices during welding, the sheets are cut off one millimeter;
3. Reinforcement aluminum sheetsWhen the increase in the inner wall or the middle portion. This allows you to do a preliminary sweep during welding;
4. Glass fiber reinforcementWhen they pave the middle part. Other parts are made from polypropylene;
5. Reinforcement composite. Kompozitnoy material used in the manufacture of the external and internal balloons - polypropylene and fiberglass.

The apparatus of reinforced plastic pipes

Reinforcement involves drawing up a rigid framework. Since polypropylene is characterized by its ductility, involves applying reinforcement preservation length and width of the prototype, even at elevated temperature.

The fluid that passes through the communication adaptations, does not affect the wall thickness, they do not narrow and does not become clogged over time.

For internal use a base layer of polyethylene balls, which increases service life by acting as a supporting wall. To the adhesive composition through a ball attached aluminum foil, which stabilizes the texture, since aluminum prevents the diffusion of oxygen.

The end of the foil sheets butt welded with a laser beam. Laser joints are strong, do not require additional connections.

The decorative and protective function is performed by a white coating of the outer polyethylene layer.

Structural feature reinforcement consider areas:

• polyethylene;
• glue;
• aluminum;

Reinforced models have a long service life. Polyethylene, which is crosslinked and the inner zone, giving them smoothness. The two polymeric zones protect the central portion of the aluminum from the creation of a galvanic couple with the steel and the brass part of communication devices. Reduce heat conduction and condensation.

Guarantor durability diameter is reinforced products. The outer diameter coincides with the internal, that is taken into account when choosing.

Any embodiments reinforced pipes bent several methods:

• manual bending. Importantly, do not do it in one step, so as not to break;
• special tool - more secure;
• spring - for bending small radii models;
• version of the application and heating of the sand dryer construction.

For thermal highways selected design with a low coefficient of thermal expansion. Equipment for hot and cold water, for the water sewerage can be used varieties fiberglass products.

To simplify the operating conditions of the pipelines, it is recommended to use reinforced polypropylene variants. They are characterized by vitality and security.

Pros and cons of reinforced plastic pipes

Advantages:

• invulnerability corrosive processes;
• throughput 1.3 times higher relative to other products of similar diameter;
• resistance corrosive environment;
• low weight and ductility;
• low thermal conductivity;
• installation with a minimum of waste and a list of tools;
• soundproofing;
• anti-static;
• repairability without requiring welding;
• aesthetic appearance.

Disadvantages:

• Attenuation of connecting points at constant temperature difference;
• When laying need to take into account the length of the supply;
• Bends should provide compensation loop.

The valves are suitable for both exterior and internal masonry. This increases the useful floor space.

Mounting

At installation time, cost little. Pipes are welded, like others of homogeneous plastic ball. When the exploitation is not delaminate and remain an integral structure.

To carry out installation work of laying the pipeline do a drawing with all the detailed snaps. This simplifies installation. Products are cut to length, according to the project drawing. Heated joints and fittings, and fixed so that they stick together. After the "hot" sizing system is ready for operation.

Important to remember:

Polypropylene model PPR-AL-PPR must be cleaned before connecting. To install the pipe with aluminum take longer than for models with fiberglass.

At the same time, the fiberglass pipe PP will not be in need of special sweeps. Are joined by soldering, the installation is done quickly.

Reinforced polypropylene product is much more effective than traditional metal. Over time, they will completely replace them.

Precautionary measures

Connecting parts are not always reliable. Exposure to temperature changes, as well as water pressure, weaken joints that may leak. The best solution is to leave all the connections in the public domain, not zamurovyvaya them.

Reinforced pipe condensed. They are either insulated or hidden in the wall while using a collector wiring diagram of all the necessary instruments, leaving sockets connections available.

Limits the flexibility of communication devices are according to the markings. Curved tube correctly is more durable. When the pressure of water and air, sometimes broken integrity. Then there is a break at the fold.

When using reinforced pipes are used in the creation of new technology pipeline. A landlord can own hands to build water supply, without using specific knowledge and not hiring experts. Reinforced products have become a fundamental design in modern buildings.
