Materials used for Plumbing

Copper
Copper pipe is the most popular type of piping
used in domestic hot and cold water systems. It
is also used in domestic central heating
systems. Copper is a good conductor of heat, it
is also relatively easy to bend when cold. It
will not corrode to any great extent. Copper
connections can be easily soldered.

Mild Steel
Mild steel or black iron pipe as it is normally
known is used in large scale industrial plumbing
such as factories, schools and hospitals. Black
iron pipes are generally much larger in diameter
than copper pipes. They are joined by threaded
fittings or by welding. The greatest disadvantage
to black iron pipe is the fact that it will rust
and corrode easily.

Lead
Sheet lead is used for a variety of different
uses within the construction industry
i.e.- Flashing round chimneys and dormer
windows. Flashing round where a flue projects
through the roof. Dressing round special window
features. Lead valleys. Lead is no longer used
in pipes as it can contaminate water and make it
poisonous.

Plastic pipe
Plastic P.V.C. pipes are generally used as waste
pipes from domestic sanitary ware. They can be
used in sinks, bathrooms and also in underground
drainage. Vent pipes are generally also
P.V.C. Several new types of plastic pipe have
recently become available for cold water systems
although they have not become very popular as yet.
