SADIP Product Specification

 

Fittings Specifications
PIPES

  • Ductile Iron (Socket & Spigot) pipes manufactured by centrifugal process to meet in every respect the requirements of International Standard ISO 2531, BSEN 545.

  • All Pipes have standard 2 GS push - on joint.

  • The standard effective length of the pipe is 6.0 meters. However, 10% of the pipes can be supplied shorter than 6 meters as per ISO 2531.

INTERNAL COATING:

  • All pipes are lined with Portland cement (Sulphate resistant type V). Cement applied by centrifugal process in compliance with ISO 4179. Thickness of cement according to ISO, BSEN standards.

On request a seal coat of epoxy of bituminous coating can be applied on the cement.

EXTERNAL COATING:

  • Pipes are coated externally by pure metallic Zinc (minimum 99.995 purity) at the rate 200gm/m2, which represents 50% more than requirement of ISO 8179. Zinc is then covered by 120 microns of bituminous paint.

MARKING:

The following marking is casted on each pipe (on the socket):

  • The nominal diameter of the pipe (DN).

  • The type of socket (STD) which means standard type.

  • The manufacturer mark (SADIP).

  • An indication that the casting is of the ductile iron (2GS).

  • Date and ladle no. of casting.

...other markings can be made on request.

  • Maximum angular deflection will not affect the sealing of rubber gasket.
  • Note SADIP can offer any different specification of coating as per customer requirement.

2 FITTINGS

  • Ductile iron fittings (Casted in a Sand mould) are in accordance with the international standard ISO 2531 & BSEN 545. Fittings socket is of a triduct push-on joint. Flange joints are dimensioned and drilled according to ISO 2531, PN 10, 16 or 25 (PN 40 for diameters < or = 300). All fittings are class K12 except the Tees which are class K 14.

INTERNAL COATING

  • All fittings are lined internally with portland cement (sulphate resistance type V) as per ISO 4179.

EXTERNAL COATING

  • All fittings are coated externally by pure metallic zinc (minimum 99.995 purity) with thickness of 100 microns. Zinc is then covered by 120 microns of bituminous paint.

MARKING:

  • The marking of fittings is in accordance with the standard ISO 2531.

3 JOINTS

  • The rubber gasket for the pipes is standard type where as triduct gasket is offered for fittings which is similar to tyton joint. These gaskets are EDPM rubber according to ISO 4633.
