Technical specification of ductile iron fittings

Ductile iron fittings in accordance with the International Standards ISO 2531 & BSEN 545. Fitting socket is of triduct push on joint. Flange joints are dimensioned and drilled according to ISO 2531 .PN10-16OR 25

All fittings are class K12 except the Tees which are class K14

Internal coating;

 All fittings are lined internally with Portland cement per ISO 4179

External coating

All fittings are coated externally by pure metallic zinc with thickness of 100 microns. Zinc is then covered by 120 micron of bituminous paint

Marking; the marking of fittings is in accordance with the Standards ISO 2531

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

FLANGED PIPES

Flanged pipes are class K9, centrifugally cast with welded flange PN10 -16 or 25. The gasket flange is normally EPDM Elastomer rubber as Per ISO 4633. The normal gasket can be improved by steel reinforced rubber gasket

PE SLEEVES.

Poly ethylene sleeve 200 micron thickness is supplied in accordance with ISO 8180 and AWWAC-105

Spheroidal Graphite cast iron

- Good resistance to natural corrosion

Easily machined

Spheroidal graphite (S.G) has

Higher mechanical feature

Higher deformation capacity

A high modulus of elasticity

A better shock resistance 

Rubber expansion joints  

Rubber expansion joint are specially designed in spherical shape and the rubber ball is reinforced with steel wire and nylon and then finally vulcanized under the high pressure. The joint is supplied with floating metallic flange or FMCB union

Because of its spherical ball shape, it poses high resistance to explosion and its elastic structure enables pipeline system
