SDS is producing ductile iron pipes in the range of 80 mm to 800 mm diameter and fittings in the range of DN80 mm to DN 2600 mm.

SDS is awarded ISO 9001/9002 since 1998.

SDS product is complying with international standards, i.e. ISO 2531 & EN 545 and can provide costomized product as per customer request.

Pipe Specifications

Ductile Iron (Socket & Spigot) pipes are manufacturered by centrifugal process to meet in every aspect the requirements of International Satandard ISO2531, BS EN 545.

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.

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.

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.

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.
