Heating in the private house of polypropylene pipes with his own hands

Polypropylene tubes can be reinforced with fiberglass or aluminum

Description of the design features, purpose and application of the product leads the manufacturer in the technical data sheet. Table, as an example, cites the VALTEC products manufacturer (Italy):

Products with an inner insert of aluminum foil is preferably used for heating. Reinforcement of polypropylene pipes with fiberglass also enables their use in the radiator circuits, underfloor heating and hot water supply of private homes. However, tubes with an internal layer of fiberglass fibers allow slight elongation linear portions during heating and oxygen permeability.

Specifications reinforced pipes made of polypropylene (manufactured VALTEC):

Fittings and valves for heating systems made of polypropylene similar random copolymer pipe material. unthreaded elements intended for connection into a socket in which the pipe is inserted into the fitting body. The inner diameter of the connecting parts (corner 90º and 45º, joints, adapters, tees, valves and crosspieces) corresponds to the outer diameter of the pipe. The linear thermal expansion negate ready compensatory loops or weldments self-fulfillment.

Clips (single and blocks of clips) are designed for direct mounting, horizontal or vertical pipe runs along the walls. Step installation fastener (recommended by manufacturer) depends on the size of the pipe and qualitative parameters of the coolant. Clamps of the same materials are used for fixing the PP pipe of large diameter. Fastening may be rigid or floating, a small gap will enable freewheel during thermal expansion.

Polypropylene tubes in a water heating circuit private homes

Pipework transmits thermal energy flow from the boiler to the instrument. Water - a traditional coolant heating systems for country houses. Amorphous polymers to aggressive environments under high temperatures is the guarantee of durability pipes. The inner surface of pipes provides a negligible flow resistance of the directional motion. Impurities contained in the coolant in suspension (organic compounds hardness, scale, sand particles), the formation of deposits on the walls of the tubes of polypropylene. articles reinforced aluminum exclude oxygen from the heating system from a pipeline. A metal foil layer reduces the risk of corrosion of the boiler heat exchanger, increases the service life of the whole system. Numerous materials, diagrams, videos, heating their own hands in a private home can be easily found on the Internet.

Emergency freezing tube wiring is not threatened destruction polypropylene tubes. After defrosting water restores the original properties of the material. However, remember that warm the pipes made of PP with an open flame can not be!

Increasing the linear dimensions of the tube during heating, perhaps the only significant disadvantage of polypropylene products. Reinforcement aluminum foil decreases in times indicator of thermal expansion and increases klassnosti pipes.

Important! In suburban homes for heating antifreeze of propylene is not used (allowed to pipe material "nezamerzayku" coolant - steel, copper, brass and plastic, rubber outer loop).

heating scheme: 1 - polypropylene tubes; 2 - valve ball; 3 - cocurrent radiator valve; 4 - expansion; 5 - circulation pump; 6 — check valve; 7 - a group of security; 8 - a radiator; 9 - thermostatic valve; 10 - a radiator valve; 11 - the plug; 12 — Majewski crane; 13 - ball valve; 14 - the plug; 15 - Thermostatic head

Given that the optimum pressure in the boiler domestic circuit 1,5 ÷ 2 bars, the heat source is as close to the user and the temperature in a building does not fall below 5 ° C, we conclude: aluminum reinforced polypropylene - an ideal material for a wiring pipe privately house.

Rules for the production of thermal contact welding

Heating systems of polypropylene produced at room temperature of not lower than 5 ° C. Consumables for heat sealing (component parts) must match the destination (PPRS).

compound Steps polypropylene tubes using soldering

The sequence of manufacturing units at the work site:

• Res produce pipes for special scissors provisional marking on the housing;
• Preparation cut surface comprises chamfering to a depth of 1 mm at an angle of 30 ° and degreasing with acetone pipe end;
• melting mark boundaries - the end of the pipe pencil applied restrictive risk;
• processing workers soldering surfaces;
• heating tool;
• melting items (with an exposure time ranges diameter pipes device passport, and alignment of parts with the iron casing);
• docking assembly without displacement and rotation elements;
• cooling.

Temporal regulation manual thermal welding process (standard values):

Voltage to electric soldering iron for polypropylene - 36B. Tools work from home network requires a tripping machine.

After cooling compounds check the straightness of the joint, the uniformity of the weld bead and no welding defects. The number of connecting nodes, when the rules of contact welding does not affect the capacity of the system. Low resistance in welded parts due to the physical properties of the material and the method of connection without reducing the passage section of the pipe. Hydraulic testing the strength and density of the PP pipe system is carried out 16 hours after welding.
