Ductile Iron Pipe And Fittings

Main Technical Specifications

Standards:

ISO2531; BS EN545; EN545; EN598; GB13295; ISO7005-2; EN1092-2

 

Production Process:

Lost Foam or Sand Cast

 

Internal Lining:

Ordinary cement mortars: Surphase resistance cement; Epoxy paint brushing; Fusion Bonded Epoxy coating etc.

 

External Coating:

Zinc coating: Metallic zinc (for centrifugally cast pipes and zinc rich paint coating for non-centrifugally cast pipes and fittings.

Bitumen coating, Epoxy paint brushing; Fusion Bonded Epoxy Coating etc.

 

Pressure rate:

PN10; PN16; PN25; PN40

 

Thickness:

K9; K10; K12; K14; GGG50

 

Jointing Materials:

SBR or EPDM rubber rings for sockets end(s)

SBR or EPDM rubber gaskets, Galvanized steel bolts, nuts and washers for flanged joints.

 

Main Mechnical Properties

  1. Tensile strength: 420 Mpa Minimum
  2. Elongation: Fittings and non-centrifugally cast pipe are 5% minmum; centrifugally cast pipes are 10% minmum.
  3. Hardness: HB250 maximum for fittings and non-centrifugally cast pipes and HB230 maximum for centrifugally cast pipes.

 

We also have the cement mortar coating curing skills which will keep the coating quality much better in winter.

 

And the FBE(Fusion Bonded Epoxy) coating pipe length will reach 6m.
