How to choose a polypropylene pipes for heating homes .Reviews .

On what is the choice in favor of polypropylene pipes

Selection of plastic pipes in all their diversity as the primary structural material for domestic pipelines for various purposes has become almost the norm.Metal steel or even copper pipes gradually losing market of such equipment in the category of economy-class polypropylene and polyethylene (PE80) products, and the reasons are quite obvious.

For any choice of construction materials is always the three main questions: how much it will cost, how fast to install and how long will last.Top polypropylene pipes for heating and water supply system harmoniously fit in all criteria.Judge for yourself:

• polypropylene pipes of any type are chemically inert and capable of receiving low-quality heat transfer fluid (if only it could to support the heating boiler and pumping equipment);
• deposition system corrosion products and impurities on the walls of the conduits is much slower than in metal grids;
• pipe segments PN20 category and above are able to keep the operating pressure central heating systems and for autonomous heating conditions have ideal mechanical properties;
• ecological purity of the material under normal operating conditions;
• heat resistant internal coatings (up to 120 degrees) and low susceptibility to external fire;
• relatively low price: meter polypropylene pipe category STR032P20X 32x5,4 S2,5 (PN 20), suitable for heating and hot water, varies about 90 rubles;
• simplicity and economy of installation work under the most difficult layout design schemes;
• finally aesthetics: Polypropylene heating pipes of all sizes fit harmoniously into the interior without additional decoration.

Types of products made of polypropylene: how not to be mistaken in choosing

Before choosing polypropylene pipes for its heating system, it makes sense to at least skim product mix and labeling of these products.Regulatory requirements for such products to GOST R 52134-2003, where you can learn all about the pressure pipes and fittings in thermoplastic (connecting parts) to them.

• kinds of plastic pipe of this type: PP-H, PP-B and PP-the R, in the Russian edition labeled as PP type 1-3;
• scope of application: hot and cold water, heating;
• extensive assortment of sizes: Polypropylene tubes may have an outer diameter of 10 to 450 mm and a nominal wall thickness of 1.8 to 40 mm;
• thermal resistance, for example, the brand PP-H 100, it is 110 degrees, and this will agree, is not bad.

Many retailers and manufacturers use its own marking products, but if you see on the price list 32h5,4 S 2,5 PN20, understand that this is a polypropylene tube with an outer size of 32, the wall 5.4 and nominal cross-section of 2.5 millimeters,it is suitable for domestic heating network wiring.PN10 meets with stenochkoy 2.0 - take only cold running water in the country (almost garden hose).

variants and installation of PP pipe

1. Internal reinforcement aluminum.The rigidity of the structure, mechanical strength and heat-conducting properties are rising - the pros are obvious.This sandwich - the assembly and will last longer, and warming would be better.Structurally - just one tube to another, lined with aluminum foil (solid, corrugated or perforated).The last performance of the least successful, since it allows the oxygen penetration into the joints.
2. sealing layer of fiberglass.Lightweight variation of the metal structure.Extruded outer diameter insulated fiber glass fiber cloth.
3. Composite materials as a layer.Another way to reduce weight and improve its performance.

note that additional insulation made by manufacturers and nearly three-layer heat transfer surface makes polypropylene pipes heating is absolutely safe, that should definitely be considered when choosing intrahouse wiring.

Laying and installation of polypropylene pipes, as we have said, is fast enough, given the necessary tools and skill.The required range of compounds can pick up on their own design scheme, but it makes sense to entrust these problems to professionals.In any case, installation of the subtleties of PP pipes offer to evaluate via video instructions.
