Product Description
Copper tube for plumbing and gas is suitable for drinking water purposes, both hot and cold, sanitation, central heating, gas
and general engineering applications. Plumbing copper tube is available in nominal size from 6mm to 108mm (from 1/4" to 4").
The range of plumbing copper pipe is available as hard temper and half hard temper in straight length, soft annealed temper in coils.
The copper tube is available and in a variety of wall thickness to meet the safe working pressure requirements for varying applications.
The copper tubes are manufactured according to ASTM B88 standard (for American), EN 1057 standard (for European),
AS 1432 standard (for Australia).

Material
The copper tubes are made in compliance with UNS C12200 (Cu-DHP) alloy, with copper content more than 99.90% and
with phosphorous range of 0.015% to 0.040%
