ISO2531/EN545 Ductile Iron Pipe Fitting: Internal ordinary portland cement mortar lining comply with ISO4179, external sprayed metallic Zinc coating (min.130g/m2) according to ISO8179 + bitumen painting (min.70μm) according to BS3416. Flange drilling EN1092-2, PN10/PN16

Product Description

Our ductile iron fittings are produced with vacuum lost foam Process according to standard ISO2531 EN545 and EN598.

Advantages of vacuum lost foam technique:

a) Higher productivity and faster delivery.

b) The castings have excellent finish with much less pinhole or blowhole.

c) With even thickness.

d) Maintains high dimensional accuracy, which is so vital for the leak-tightness.

e) Any combination and length of fittings can be more flexible.

Packing and transportation of Ductile Iron Fittings:

Compared with ductile iron pipes storage and transportation, Fittings are much easier.

If Fittings size≤DN300, we arrange packing in timber cage or wooden cartons. For those ≥DN300, we arrange packing in wooden pallets.
