Tubing made of copper was introduced in about 1900, but
didn't become popular until
approximately
1950, depending on local building code adoption. Common wall-thicknesses
of copper tubing are "Type K", "Type L" and "Type M";[2] Type "M" is
relatively inexpensive (until recently. Since 2002 Insert non-formatted
text hereInsert non-formatted text here copper prices have risen
exponentially due to rising global demand and a stagnant supply.) and
relatively thin-walled and generally suitable for condensate and other
drains, but generally illegal for pressure applications, Type "L" has a
thicker pipe wall section, and is used in residential and commercial water
supply and pressure applications, Type "K" has the thickest wall section
of the three types of pressure rated tubing and is commonly used for deep
underground burial such as under sidewalks and streets, with a suitable
corrosion protection coating or continuous polyethylene sleeve as required
by code. Types "K" and "L" are generally available in both hard drawn
"sticks" and in rolls of soft annealed tubing, Type "M" is usually only
available in hard drawn "sticks".
In the plumbing trade the size of copper tubing is measured by its
nominal diameter (average inside diameter). Some trades, heating
and cooling technicians for instance, use the outside diameter
(OD) to designate copper tube sizes. The OD of copper tube is
always 1/8th inch larger than its nominal size. Therefore, 1"
nominal copper tube and 1-1/8th" inch ACR tube are exactly the
same tube with different size designations. The wall thickness of
the tube, as mentioned above, never affects the sizing of the
tube. Type K 1/2" nominal tube, is the same size as Type L 1/2"
nominal tube (5/8" ACR).
