Pipes for water supply - the most exploited life support system for human habitation. Used from the distant past, steel or cast iron pipes are not resistant to corrosion and require frequent replacements. The use of polymers as a material for pipes has led to an increase in the life of water pipes up to 40 years.
Modern polymeric materials for pipes are endowed with exceptional operational properties. They can operate at high pressures up to 30 atmospheres, high temperatures - up to +90 degrees, can be used for external water supply, and are resistant to direct solar radiation. When freezing, polyethylene pipes do not lose their shape and performance. A disadvantage for polypropylene and polyethylene products is a significant coefficient of linear expansion. The advantage is low heat dissipation.
Plastic pipes are an inexpensive, reliable and very quickly mounted material.
Plastic pipes for water supply are mounted in cold, hot water and heating systems. Choosing pipes to replace or install a new water supply system, it is necessary to find out their operational characteristics and the conditions in which they will be operated. If for cold water supply you just need to find out the pressure the pipe can withstand (in atmospheres), then for heating pipes you need to know at what maximum temperature they can work for a long time. The connecting elements are the so-called “fittings”. The diameter of the pipe for home water is optimal at 3/4 inch.
Plastic pipes for water supply are mounted in three ways. PVC pipes are connected by the method of "cold welding", a special solution softens the walls of the connected elements, which, when cooled, create a solid structure. The internal walls of the polypropylene pipe are heated with a special soldering iron, and the fittings are connected, after cooling, the structure is ready for operation. Polyethylene and plastic pipes are crimped when the fitting is put on the pipe, and with the help of a mounting tool, the required joint density is achieved. The advantage of polymer water pipes is the possibility of self-assembly, many men will be able to assemble a designer - a plastic water pipe.
Copper plumbing - operated for centuries.
Copper pipes for water supply are resistant to erosion, withstand temperature extremes from - 200 to +250 degrees Celsius, there is practically no linear expansion, they suppress harmful microorganisms. They can be operated in systems with high pressure up to 50 atmospheres. High heat transfer makes it possible to use in heating systems and always in hot and cold water supply. The price of materials and work is very high.
In the construction market, there are plastic pipes that can meet the requirements for operation in any conditions, from enclosed spaces to open spaces. Choosing pipes for water supply, you can focus on those that satisfy your needs.
