1.ISO 9001:2008/24001:004/28001:2001 2.ductile iron fittings 3.high quality & competitive price.

1.Made according to ISO9001:2008 & ISO 9001:2000.

2.Ductile iron.

3. Advanced technique. We have the blast furnace, intermediate frequency furnace, water-cooling metal mould centrifugal tube casting machine and many other high tech equipment. Production line of clearly-defined responsibilities and rational division of  labor is made, thus, 200,000 tons water-cooling metal mould centrifugal ductile iron pipes are manufactured.
