Copper pipes in heating and water supply systems

Copper pipes in heating and water supply systems

Copper

The pipeline is in the lead

Among the pipelines of the elite class. Copper

Pipes have antibacterial properties,

Impermeable to gases, easy to hold

High pressure and temperature. Copper

Pipes do not collapse under the influence of

Ultraviolet rays (in contrast to

Polypropylene pipes), for them is typical

Low coefficient of thermal expansion

(About 7 times lower than in polymeric

Materials). Copper pipeline (on

Soldered joints)

Withstands pressure up to 40 atm. And temperature

Up to 600 gr. Celsius. Copper pipes can be

To be embedded in the walls of the building (with

Certain installation rules). When

Connecting copper pipes with other metals,

It is necessary to consider the possibility of destructive

Galvanic interactions of dissimilar

Materials, for example, copper with aluminum.

Copper can be processed in a wide

Temperature range. It is important that when

Lowering of temperature, strength of metal

Increases. Operating temperature

The range of copper pipes is wide - from -200 to

+500 gr. Celsius (without regard to characteristics

Material of joints). For

Different types of pipes, the maximum permissible

Working pressure varies from

Several dozen to several hundred

Atmospheres at 100 g. Celsius. This property

Copper allows her not to be afraid of repeated

Freezing of water inside the pipes. Similar

Load, in addition to copper, stands

Only steel.
Copper Pipeline

Is universal. Pipes and fittings of single

Standard are applied in all types

Communications: water supply, gas supply,

Heating systems, oil pipelines,

Conditioning systems, etc.

Assortment of pipes and fittings is very

It is wide and allows you to mount any

Pipeline system. Copper is almost

Is completely re-processed,

Does not pollute the environment. Copper

Pipes have a very long service life.

From practice it can be argued that

Communication from copper pipes inside

Buildings serve almost as much as

The building itself is maintained.
When

Copper is used in the production of pipes

CU-DPH (DIN 1412). The Cu + Ag content is more than 99.9%,

The residual phosphorus content of about

0.015%. From these figures it follows that such copper

Has a high anti-corrosion

Properties, easy to solder and give in to

The welds are easily cut and bent.

The method of joining copper pipes is simple

And reliable. The most common type

Connections - high temperature brazing

Silver-bronze solder.
