Our products are water - cooling metal centrifugal casting ductile cast iron pipes such as "T""S""N1"types of joints with the effective length 6m; nominal diameter ranges form DN80mm to DN2400mm, 4179, according to the standard ISO2531, 8179.
(1) Standard dimensions and weight of N1 type joint (K 9 class, standard effective length: )
The Data of Beitai Ductile Iron Pipes:
(2) Standard dimensions and weight of S type joint ();
(3) Standard dimensions and weight of T type joint ()
Smelting and Molten Iron Spheroidization
After smelting by mid - frequency furnace we treat molten iron with spheroidizing agent to adjust its composition.;
Centrifugal Casting and Extracting from Molds
On a centrifuge, water - cooled metal mould process is adopted in casting, Molten iron in the cupola is heated by an electric furnace and after being spheroidized, it is cast into a pipe mould turning at a high speed continuously.
Our products are water - cooling metal centrifugal casting ductile cast iron pipes such as "T""S""N1"types of joints with the effective length 6m; nominal diameter ranges form DN80mm to DN2400mm, 4179, according to the standard ISO2531, 8179.
ductile iron pipes
Manufactured using centrifugal casting method that ensure consistency in dimensions and compactness in its microstructure. All pipes undergoes stringent quality control. Sizes range from DN80mm to 900mm in diameter in standard lengths of 6 meters.
Cement mortar is lined onto the internal surface of each ductile iron pipe to prevent water from being polluted and to increase ability of transmitting water. All pipes are externally coated by metallic zinc and sprayed by bitumen according to ISO8179. All pipes are internally centrifugal lined by cement mortar lining according to ISO4179.
During finishing processes, the pipes will pass through visual inspection, zinc spraying (if ), internal grinding of spigot and socket, roundness checking, hydraulic pressure testing (or air ), grinding,ring test chamfering, dimension checking and mechanical properties test etc, in order to assure the quality of pipes.
To prevent corrosion and give the pipe a good look every ductile iron pipe is coated with bituminous paint, at the same time, it is necessary to inspect external coating quality.
