Product Description

Model No.: Product Origin:China Brand Name:Beitai Price Terms:FOB Dalian or CNF Payment Terms:L/C Certification: Description:Product Name: Ductile Cast Iron Pipe and FittingsPlace of Origin: ChinaOur products are water-cooling metal centrifugal casting ductile cast iron pipessuch as "T" "S" "N1" types of joints with the effective length 6m; nominal diameterranges form DN80mm to DN2400mm, according to the standard ISO2531, 4179, Data of Beitai Ductile Iron Pipes: (a)Standard dimensions and weight of N1 type joint (K 9 class, standard effectivelength: 6m)(b) Standard dimensions and weight of S type joint (ditto);(c) Standard dimensions and weight of T type joint (ditto) ;Smelting and Molten Iron Spheroidization:After smelting by mid-frequency furnace we treat molten iron with spheroidizing agentto adjust its composition.Centrifugal Casting and Extracting from Molds:On a centrifuge, water-cooled metal mould process is adopted in casting, Molten ironin 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.

The molten ironsets into a ductile iron pipe and cooled down by water then extracting frommolds according to set time strictly.

Heat Treatment:The qualified cast ductile iron pipe is put into an annealing furnace to attain therequired metallographic structure of ductile iron.Finishing: During finishing processes, the pipes will pass through visual inspection, zinc spraying(if necessary), roundness checking, internal grinding of spigot and socket,hydraulic pressure testing (or air test), ring test chamfering, grinding, dimensionchecking and mechanical properties test etc, in order to assure the qualityof pipes.

All pipes are externally coated by metallic zinc and sprayed by bitumenaccording to ISO8179.Cement Lining: Cement mortar is lined onto the internal surface of each ductile iron pipe to preventwater from being polluted and to increase ability of transmitting water.

Allpipes are internally centrifugal lined by cement mortar lining according to ISO4179.Bitumen Coating:To prevent corrosion and give the pipe a good look every ductile iron pipe is coatedwith bituminous paint, at the same time, it is necessary to inspect externalcoating quality.Price Term: FOB, C&F, CIF
