Copper and metalloplastikovye water pipes are increasingly replaced in homes as the usual steel, and modern plastic.
Both types of pipes are very much in demand during construction and repair, but copper, even despite the high price, is gaining more and more advantageous positions in the construction market.
Types of pipes
Currently, for water and heating systems, several types of pipes are used, different in materials, properties, methods of installation and operating conditions.
The most common pipes are stillRemain steel. They can be both galvanized and conventional, without coating. Galvanized pipes serve a little longer than ordinary, but they are more expensive. Steel pipes are heat-resistant, durable and long enough to serve, but they have a number of significant drawbacks: they are prone to corrosion and the assembly of pipelines from them is more difficult. In addition, tap water from copper pipes gets quite a lot of rust, which reduces the quality of such water. In addition, the inner surface of steel pipes is gradually covered with mineral outgrowths, the lumen of the pipe is narrowed due to this, which can cause problems with water supply.
Also widely used are pipes made of plastic. There are several types of such pipes: polypropylene, including cross-linked polypropylene, polyethylene, polyvinylchloride and metal-plastic.
There are two types of polypropylenePipes (not from cross-linked polypropylene): ordinary (unreinforced) and reinforced (foil). For hot water supply it is desirable to use foil polypropylene pipes. Connections of polypropylene pipes are carried out with the help of tees, couplings and various adapters. Such pipes are used for a long time, they are not subject to corrosion, they do not need to be serviced, they can be laid in stitches. In this case, polypropylene has several very significant drawbacks: the pipes are inflexible, any assembly fault is eliminated only by replacing the whole site, the installation is laborious and not expensive.
Pipes made of cross-linked polypropylene have exactlyThe same advantages as conventional polypropylene, but perfectly bend, easy to assemble and less susceptible to mechanical damage. True, their price is much higher.
Polyethylene pipes, contrary to the prevalentOpinion, are used not so rare. Their undoubted merits are ease of installation and low price. At the same time, the pipeline made of polyethylene becomes very fragile at low temperatures, and therefore it is infrequent in our latitudes.
Polyvinyl chloride is used for water pipes andHeating is rare enough because of the myth of its toxicity. However, harmful substances are released from polyvinylchloride pipes only in case of fire. At low temperatures this does not happen. But polyvinylchloride has the same drawback as polyethylene: brittleness at low temperatures. In addition, the tube of this material has a harmful effect of ultraviolet radiation.
Metal-plastic combines advantagesMetal and plastic pipes. This is the main competitor of copper, but it also has a lot of flaws, such as the impossibility of sealing fittings in the wall, unreliability and high pressure in the junctions. However, from the point of view of ease of installation and cheapness, this is one of the best options. That is why the most widely available in the market is metal-plastic and copper.
So, copper pipes are becoming more and moreIn demand. So why should you buy them? To begin with, copper is a material with excellent resistance to corrosion, high and low temperatures. In addition, copper pipes have good bactericidal properties, flexibility and plasticity, which is the result of incredible durability. Theoretically, copper pipes can serve you (as well as your grandchildren and great-grandchildren) faithfully and truthfully, up to 200 years, although more often sellers of copper pipes and joints cautiously speak after all about 50-60 years. In addition, copper is universal in use. Copper pipes and connections are excellent for manufacturing various engineering networks: plumbing, heating, gas and others.
The strength and stability of copper is incredible. So, chlorine and fluorine, present in water for its disinfection and destroying ordinary steel pipes, connecting with copper, create a protective layer on the inner surfaces of copper pipes, thereby strengthening your water supply. In addition, copper pipes are gas-tight. If properly installed, a copper or copper heating system will be much more resistant to any external influences than a plastic or steel system.
Copper has an excellent thermal conductivity, whichIt is very important for the construction of the heating system. In this case, it is necessary to isolate copper from aluminum, which is often used for making heating batteries. Copper and aluminum joints should be made of steel or plastic only, and aluminum and copper parts themselves should not come into contact, otherwise a chemical reaction will begin between them, leading to a reduction in the service life of copper pipes.
Workers who will perform the installation of copper pipes will appreciate another advantage of this material. Copper is extremely easy to bend, cut and join.
Disadvantages of copper
Despite the many advantages of copperWater, heating and other systems, they have their shortcomings. For example, although the cost of copper pipes is not much higher than the cost of pipes made of other materials, and sometimes even lower, the cost of installation and connections is quite high. It can be compared with the cost of the pipes themselves. In addition, only specialists can perform the installation of a copper pipeline, and an open flame can not be used in the installation.
Rigid water is highly undesirable for pipes fromCopper, because it can cause damage to them. Therefore, it is often necessary to install a pre-filter in the system, which also does not cheapen the work.
This step is not mandatory, but will significantly prolong the life of your pipeline.
When installing copper pipes, it is necessary to resort toAssistance of skilled workers. If this condition is met, as well as the use of quality pipes and fittings, the copper pipe will serve you faithfully for the rest of your life, and the quality of the water from such a water pipe will not decrease, as it happens in steel pipes. The copper pipe joints are sufficiently reliable, so you can forget about their maintenance and be sure that they will not leak, as is often the case with plastic pipelines.
