Application of reinforced plastic and polypropylene pipes was made possible through a formal resolution of the document SNIP 2.04.05-91 "HVAC" and SNIP 2.04.01-85 "Internal water supply and sewerage of buildings".However, it should be carried out only one requirement - the manufacturer must have a license.

for the material from which the manufactured products must meet the sanitary standards of the Russian Federation, the coolant temperature must be within 90 degrees, and the pressure should be measured not more than 10 atm.Let's compare the advantages and disadvantages of MP and PP pipes.

Plastic pipes are composed of five layers, which are made of polyethylene, adhesive and aluminum foil.When installing these pipes is necessary to distinguish between three types of connection: Plug, conditionally detachable and permanent.Two of these include fittings that immediately puts them under the supervision of SNIP.

When installing this type of high-quality pipe manufacturers offer immediate order and fi

ttings.Among Plus MP pipes plasticity, which allows their use even in geometrically complex premises;oxygen impermeability;low probability of corrosion;resistance to low temperatures.But the ultra-violet rays (ie direct sunlight and) can significantly harm MP pipes.In addition, they must be protected from mechanical impact, flames and sparks, which means their "hidden" installation.

As polypropylene pipes, there should be noted the following: the basic element is a Polypropylene Random Copolymer, which allows you to use them in pipelines of water supply, heating and air conditioning.Tubes connect the specialized staff using propylene or combined fittings, or else simply welded.

The main difference from the MP pipes is increased because of the wall thickness diameter (1.7 times).In its other characteristics are similar to the PP pipe MP pipes.But the disadvantage is the inability to change direction.At the moment, we created three kinds of pipe PP: PN 10 (for cold water), PN 20 (for hot and cold water) and PN 25 (for heating).

As for the price, the pipes themselves MP cheaper than the PP, but with the purchase of the fitting you will spend much more.But when installing systems installers will cost you about the same cost.
