    Good manufacturing and quality controlling system can assure to make perfect products

  • 2

    Centrifugal casting machine with

    water- cool ing metal mould.

    High quality molten iron with its low content of sulphur, phosphorus and other trace elements, together with the Delavaud Process of the world advanced level, combines to produce perfect quality iron pipes.

  • 3

    The annealing furnace of

    horizontal type performs the

    treatment ductile cast iron pipes

    75 meter long with 45 meters

    effective wo rking length and

    equipped with computerized

    control system up from siemens

    in Germany. The furnace is up

    to now the most advance in the

    w o r l d t e c h n o l o g i c a l l y .

    No leakage will be appeared on the socket and

    spigot when tested under specified pressure.

  • 4

    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, dimension checking and

    mechanical properties test etc, in order to assure the quality of pipes.

  • 5

    After the precise quality inspecting, Ductile Cast Iron Pipes possess

    reliable strength, correct dimensions, uniform wall thickness, smoothly

    surface of inside and outside.
