Ductile Iron Fittings
We manufacture ductile iron fittings with the adoption of the Lost-Form techniques. The D.I fittings are made according to EN545-2010, EN598-2007 and ISO2531-2009 standard, pushed on "T" joints, "K" joints, and PN10, PN16, PN25  flange joints, with the standards of DN80-DN1600. Inside, we have cement lining, which differs into Portland cement or high alumina cement.It complies with the standard ISO4179 . Metallic Zinc can be made upon the client requirement, usually 200g/㎡in thickness, complying with the standard ISO8179. The bitumen sprayed outside is usually ≥70um. And we also provide epoxy resin and polyurethane coating inside and outside, whose thicknesses is determined upon our clients'request.
