Ductile cast iron pipes are widely used for water supply, drainage and gas transportation in municipal construction, they are related closely with our production and daily life.
Even today, with new technology and new material emerging in large numbers, ductile cast iron pipes can’t be completely replaced by other materials, they play an important role in constructions of water supply, drainage and gas transportation because of three advantages: rich and recyclable materials, economical and corrosion resistant, improved performance and increased production.
Material of pipe body: ductile cast iron
Inner coating: cement mortar lining
Outer coating: zinc coating and bituminous painting
Manufacturing standard: ISO2531 & EN545
Grade: K9
Manufacturing method: centrifugal casting
Connection: T type joining

Cast iron pipes are made of cast grey iron complying with ISO185 grade 150, they are widely used for drainage in high-rise buildings because they are solid and durable with excellent noise suppression, fire resistance, low thermal expansion and chemical resistance. They are also easy to be installed by couplings or clamps.
Centrifugal cast iron pipe system comprises non-hub pipes, non-hub fittings, joints(couplings or clamps) and accessories. It’s an ideal and economical building drainage system because of the above advantages.
Material of pipe body: cast iron
Inner coating: coking bituminous or epoxy resin paint
Outer coating: anti-rusting paint or epoxy resin paint
Manufacturing standard: ISO6594 & EN877
Manufacturing method: centrifugal casting
Connection: couplings or clamps joining
