External:
Pipes are coated externally to protect its products from the harsh corrosive environments. SADIP can offer any different specification or coating as per customer requirement. Standard types of external coating:
Zinc & Bituminous Paint Coating
All SADIP pipes and fittings are coated externally by pure metallic zinc at the rate of 200g/m2 which represents 50% increase over ISO standards, then zinc is covered by a bituminous paint of 120 microns which is more than the ISO 2531 requirement which is 70 microns resulting in increased safety and protection.
Internal:
Pipes are lined internally by sulphate resistant cement mortar lining type V. SADIP can offer any other lining or coating as per customer requirement.
Cement Lining
Cement lining is applied internally by a centrifugal process, in which the mortar is introduced into the pipe and rotated at high speed, giving excellent compaction.
