Ductile Iron Pipes
We supply and export "SUNS" D. I. pipes. The brand of "SUNS" enjoys a high reputation throughout China and thewhole world. Our D.I pipes are designed and made according to EN545-2010, EN598-2007, and ISO2531-2009  standards, pushed on "T" joints, K9, 6m and 5.6m in length, according to the specification of DN80-DN800. Inside our pipes, we have cement lining, which differs into Portland cement or high alumina cement, depending on supply or drainage pipes. It complies with the standard ISO4179 . Metallic Zinc can be made upon the client requirement, usually 130g/㎡ 200g/㎡ in thickness, complying with the standard ISO8179. The bitumen sprayed outside is usually ≥70um.
Our D.I Pipes factory has been certified by ISO9001-2000 and gets the "BV" inspection certificate. For many years, we have exported D.I pipes to Europe, Middle East, Southeast Asia, Africa etc. We also do OEM or ODM for our clients.
