Ductile Iron Pipe DN80-2600mm Ductile Cast Iron Pipes Ball Tube
Nodular Iron Tube Nodular Cas DI Fittings Reducer Tee
Description:
After using the casting molten iron of No. 18 or above and adding
nodularizing agent,
Pipes cast by high-speed centrifugal casting of centrifugal ductile
iron machine,
Call it: Ductile Cast Iron Pipes
Abbreviation: ball tube, nodular iron tube and nodular cast tube,
etc.
It is mainly used for the transportation of tap water, and is an
ideal material for tap water pipelines.
Ductile iron pipe is a type of cast iron pipe.
In terms of quality, cast iron pipes are required to have the
essence of iron and the properties of steel.
The metallographic structure of the annealed ductile iron pipe is
ferrite and a small amount of pearlite, with good mechanical
properties, excellent anti-corrosion performance, good ductility,
good sealing effect, and easy installation. It is mainly used for
water supply and gas transmission in municipal, industrial and
mining enterprises. , oil transportation, etc.

Advantage:
In the medium and low pressure pipe network (generally used below
6MPa), the ductile iron pipe has the advantages of safe and
reliable operation, low breakage rate, convenient and fast
construction and maintenance, and excellent anti-corrosion
performance.
The newly developed "Rock Shield" series of pipelines can be
applied to trenchless construction and are widely used in pipeline
construction for crossing rivers, roads and buildings. "Sai Zinc"
series pipelines use a special zinc-aluminum alloy external
spraying process, which improves the corrosion resistance of the
pipeline several times, and is widely used in the construction of
strong corrosive soils.
Anticorrosion treatment
1. Asphalt paint coating
2. Cement mortar lining + special coating
3. Epoxy coal tar coating
4. Epoxy ceramic lining
5. Aluminate cement coating or sulfate cement coating
6. Polyurethane coating
