Copper pipes for water supply : how to set up and operating features.

features and assortment of copper pipes for plumbing

When it comes to the installation of water pipes made of expensive and not very familiar material, you can safely draw the conclusion: the end users of the pipeline system are autonomous happy future tenants of private estates.Making personal distribution inside running water from copper pipes in an apartment house, in our opinion, is not rational.We will try to explain why.

1. Let's start with the fact that the tube is manufactured from copper rolling seven different compositions, technical and operational properties are directly dependent on the content of chemical additives (nickel, zinc, tin, etc.) In the final tube product.From 99.5 to 99.9 (M1 grade) of the rental of Cu + Ag, but the other alloying metals significantly expand the scope of application of copper pipes, sometimes very far from the needs of the domestic water supply.How not to make the wrong choice, and what to pay attention.
2. Copper pipes according to the method of manufacture in accordance with GOST 617 -2006, the cold-divided into three versions (hard, semi-hard, soft) and compressed, and water systems are suitable for all.What is the difference?High plasticity of copper allows to produce round pipes with outer diameters up to 60 mm with wall thickness of only 1.0.The weight of a meter length of the standard 1/2 and 3/4 (12 and 18 mm) will be as low as 0.307 and 0.475 kg, which agree quite a bit.
3. Large interior cross section with guaranteed hydrodynamic qualities allows to exploit the copper pipes in the heating and water systems from 50 to 80 years.The choice between the annealed (soft) and tube rental without firing depends on the technical conditions of the future layout of the pipeline, but the final price of the installation slightly affects.

Solid cold-copper pipes for plumbing

They not only have a higher mechanical strength, but are still a number of advantages over steel and plastic counterparts:

• high resistance to corrosion and the formation of corrosive depositsand loop hardware for water supply, even with low quality water;
• low thermal expansion coefficient, which allows the use of pipeline networks of hot water and not worry about depressurization copper fittings with pressure differentials;
• weak sensitivity to kinematic loads and resistance to external deformation;simply put: Copper water pipes can be bent as desired, but it is very difficult to break;
• design novelty effect: even the external wiring is copper looks stylish and unusual in any interior.

Information: hard rolled copper produced dimensional segments, if you need to make an extended and complex gasket with a minimum number of joints, it is best to choose a practical Bay water annealed copper pipe of the same diameter and similar in price.The workers of the quality system with the correct assembly is not affected.

waterpipe Installation of copper pipes

Copper - material quite easy to use and at the same time terribly naughty.At first, about what not to do when installing plumbing in your house:

• straight taps copper water pipes from the main pipeline networks in steel and aluminum: do not play well these metals and their direct contact in an aqueous electrolyte with a high temperature (hotwater) can lead to the rapid destruction of the connection points;
• temporary grounding of household appliances to pipeline elements: the best natural conductor of electric current than copper, not yet invented, and can penetrate anywhere.

Installation of copper water pipes is carried out by two conventional methods:

• simple soldering (not welded) gas burners or soldering lamps at low temperatures;connection pieces (fittings) and the pipe ends are stripped, and applied flux is heated to complete adhesions element;
• assembly using union nuts flare pipe: assembly is crimped connection is a pair of ordinary adjustable wrench similar to the fittings made of plastic.
