Description:
Mandev copper pipes & tubes – most precise thin wall copper tube India
Introducing MANDEV SPEC – the most precise thin-wall copper tube in India. MANDEV the only producer of the bright annealed copper tube with very low residue offers you:
Incredible gauge control.
More concentric and consistent tube.
Bigger/virtually defect-free coils.
Improved tube surface.
Higher yields.
The above benefits ascertain superior quality tubes for a superior quality end product, more tube footage per kilogram, reduced tooling problems, reduced the chance of costly leakages, increased productivity and fast manufacturing setup times.
Pancake coils are typically used in the installation of air conditioning and refrigerating systems. They are also used in OEM end uses. Pancake coils are provided in a flat coil which are two layers thick. Bunch coils are similar to pancake coils, but all of the individual loops have the same diameter much like the coil of wire.
– Produced in the following outside diameter size ranges.
— 3/16” (4.76 mm)
– ¾” (19.05 mm)
Standard available length is 50 feet. We can provide lengths ranging from 2 meters up to 100 meters as per the clients’ requirement in coil form.
Pancake coils are available in individual polythene bag, packed and stacked in corrugated box.
