PIPING

PIPING: CONNECTION OF DOMESTIC WATER:
To use for domestic water you must in regard of corrosion
avoid using first copper and then galvanized pipes (in the
flow direction of the water). Schematic view:
Comments on the two most commonly used materials:

PIPES OF GALVANIZED STEEL:

One of the major causes of damage to the water system is internal corrosion of hot water pipes of galvanized steel
systems. Normally fittings are most vulnerable to internal corrosion. Dissolved copper in the water from copper pipes
in the system, increasing the risk of corrosion. While respecting the basic rule that copper should follow galvanized
steel in water flow direction there can via branches of copper pipes from steel pipes happen some reflux because of
their own circulation, thus increasing the risk because of copper content.

PIPES OF COPPER:

Copper is usually fully resistant to corrosion in water, but as all other materials, it has its limitations. Internal
corrosion of copper due to turbulence corrosion is a frequent cause of damages. This applies particularly in bends.
Turbulence corrosion occurs when water velocities greater than 1.2 to 1.5 m / sec. certain types of water give pitting
in copper pipes. One should inquire about local experiences, or have examined the water before you use copper. Flux
residues inside the tubes should be avoided as they sometimes can cause corrosion. If these things are respected they
will very rarely happen inside corrosion of copper pipes.
