 Production process flow of ductile iron pipesÂ
 Molten iron → molten iron purification → heating and sphereodization →
spherodization →centrifugal casting → annealing→znic spraying→rounding and grinding→hydraulic testing→cement lining→cultivating→bitumen coating→packing
Â
 Quality control processÂ
 Screen material( ductile cast iron) → metallographic examination→ fast
 analysis→hardness test→twist test→ flat test→elongation test→damage test
 → type test
Antiseptic treatmentÂ
 Â
 1). Epoxy coating inside
 Â
 2). Epoxy coating oustside
Â
 3). Zinc spray
Â
 4). Bitumen coating
Â
 5). Cemen liningÂ
Â
 6).Other antisepsis treaments according to customer's request
Â
      During production process , we carry out tests on line strictly and test Items
Â
includes:  hydraulic pressure, cement linning thickness, zinc spraying thickness,
Â
bitumen coating  thickness,dimension test, impressing test and so on. Expecially,
Â
we have the most advanced  y -ray  detector to test wall thickness of each pipe
Â
precisely so that ensure pipes
