PLUMBING
Since before
the dawn of history – when primitive man first discovered
copper – the red metal has constantly server the advancement
of civilization.
Archeologists,
probing ancient ruins, had discovered that this enduring metal
was a great boon to many people. Tools for handicraft and
agriculture, weapons for hunting, and articles for decorative
and household uses were made from wrought copper by early
civilizations.
Modern man, recognizing that no material is superior to copper
for conveying water, has reestablished it as the prime
material for such purposes.
For plumbing purpose, there are four classes of copper
tube. These includes types K, L, M and DWV. All tubes supplied
to these ASTM standards is a minimum of 99.90 percent pure
copper.
These classes
and types of tubes are commercially available in the tempers
and lengths described in the Plumbing tube product range
chart. Types K, L, M and DWV are designated by ASTM standard
size, with outside diameter always 1/8" larger than the
standard size. Each type (K, L, M and DWV) represents a series
of sizes with different wall thickness. The inside
diameter depends on tube size and wall-thicknesses.
All four types are available in drawn
temper straight lengths 20 feet long. Type K, L and M are
available also in annealed temper in 8 feet straight lengths
or in long coils in sizes from 1/4 inch to 7/8 inch.
We in India, manufacture plumbing tubes
to meet the requirements of specifications established by the
American Society for Testing and Materials (ASTM).
