1) Internal Coating
Pipes are lined internally with Portland cement (Sulphate resistant type V). Cement is applied by centrifugal process
in compliance with ISO 4179. Thickness of cement is according to ISO & BSEN standards.
SDS can offer any different specification or coating as per customer requirement.
2) External Coating
Pipes are coated externally by pure metallic Zinc (minimum 99.995 purity) at a rate of 200g/m2, which represents 50%
more than the requirement of ISO 8179 (DN 900 mm and above 130g/m2 or 200g/m2 as per customer request). Zinc
is then covered by 120 microns of bituminous paint as per ISO 8179-1.
SDS can offer any different specification or coating as per customer requirement.
3) Cement Lining
The lining is then cured under controlled temperature and humidity giving it the optimum mechanical strength and also
producing a very smooth surface which reduces head losses and guarantees long-term hydraulic efficiency.
Cement lining is an acive coating, when the pipe is filled, the mortar gradually absorbs water, which becomes enriched
in Alkaline substances. Consequently, it is non-corrosive when it reaches the proximity of the metal wall. Also, cement
lining demonstrate the ability to withstand limited pipe deflection and good performance under high top loads.
