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.
