Copper Tubes/Copper Pipes
Copper Pipes are commonly used in the construction industry for water supply lines
and refrigerant lines in HVAC (heating, cooling, and air-conditioning) systems. Copper
pipes can be manufactured as soft or rigid copper and offer excellent
corrosion-resistance and reliable connections. The three most common types of
copper pipe used in residential and commercial construction are Type K, Type L, and
Type M. A fourth type, used for drain-waste-vent, or DWV, piping, can be found in
some older homes.
Copper Tubes/Pipes Applications
Type K Copper Tubes/Pipe
Copper Pipes are commonly used in the construction industry for water supply lines
and refrigerant lines in HVAC (heating, cooling, and air-conditioning) systems. Copper
pipes can be manufactured as soft or rigid copper and offer excellent
corrosion-resistance and reliable connections. The three most common types of
copper pipe used in residential and commercial construction are Type K, Type L, and
Type M. A fourth type, used for drain-waste-vent, or DWV, piping, can be found in
some older homes.
Has the thickest wall of all the common types. It is used for water distribution, fire
protection, oil, HVAC, and many other applications in the construction industry. Type K
pipe is available in a rigid and flexible form and can be used with flared and compression
fittings. It is recommended for main water lines and underground installations because
its thickness helps it withstand the pressure from backfilled earth in trenches.
Type L Copper Tubes/Pipes
Used for interior plumbing, fire protection, and some HVAC applications. It is available in
rigid and flexible forms and can be used with sweat, compression, and flare fittings. Type
L is considered the most common type of copper piping, as it can be used in many more
applications than Type K. Flexible Type L copper can be used to repair or replace old
water lines, although rigid tubing is more durable. Type L also can be used outside the
home where it will be directly exposed. Type L copper is thinner than Type K but thicker
than type M.
Type M Copper Tubes/Pipes
Thinner than both type K and L copper. Sold in both rigid and flexible forms, Type M is
used most commonly for domestic water service and vacuum systems. It can be used
with sweat, compression, and flare fittings. Type M tubing is favored for residential work
for its relatively low price; a thinner wall means less copper and thus a lower price. Type
M copper is not always allowed by plumbing codes in all areas and applications. Always
check with the local building authority for restrictions on its use.
