This question of the month discusses a pipe loop or coupon rack, sometimes referred to as a coupon rig. A coupon is a test specimen made of copper, lead, mild steel, or other metal that can measure by weight material what is lost to corrosion. If the corrosion is occurring in copper pipe, copper would be the appropriate material to use.
