10 To make the high quality products of Ductile Iron Fitting, KXD factory utilizes new equipment for machining work, hydrostatic test, shot blast, heating and Fusion Bonded Epoxy coating, in the production of Ductile Iron Fittings. In order to secure the leakage from internal pressure, KXD will do the double times of hydrostatic test after finishing 1 st Machining work and the boring of flange bolt hole or 2 nd Machining work. In accordance with KXD s Quality Control System, All of materials will be produced as the high level quality products. Before starting the manufacturing work of Ductile Iron Fittings, all of shop drawings shall be prepared and submitted to the client if required. And also, If some Fittings are Non Standard Fittings, KXD will submit the concerning drawing to conform from the client. As per approved shop drawing, each part of patterns for Ductile Iron Fittings shall be assembled. Each pattern is made from polystyrene molds. After assembling the pattern, QC engineer will inspect all dimensions, ovality and straightness of it. Before the preparation of mold in the cast sand box, the polystyrene pattern shall be waxed with unburned coating materials. This is one of the process to secure the shape of Ductile Iron Fittings. 10

11 The waxed pattern shall be carefully placed in a molding box (flask). The flask is filled with molding sand and the sand compressed around the pattern by automatic vibrator System. Cores which form the internal profile of the Fitting are produced with the pole of polystyrene. Raw materials such as Pig Iron, Scrap Iron, Scrap Ductile Iron are charged into the induction furnace in controlled quantities and melted. The molten cast metal is analyzed, the chemical composition and temperature shall being adjusted. Ductile Iron is produced when a measured volume of this base iron is tapped into a treatment ladle which has been pre-charged with a weighed amount of magnesium bearing ferro alloy. Whilst transferring the nodularised iron into the pouring ladle, the final inoculation occurs. After the molten cast metal is poured into the molding box (flask), the cooling System should control to ensure the good quality. After pouring the molten cast metal, the castings are taken off from the molding box, shot blasted and then sent to the dressing area to remove metal flash. The fettled castings are checked and corrected for dimensional accuracy and quality before proceeding machining 11

12 Before the hydrostatic test to secure the casting defect, the flange face and socket part of Ductile Iron Fittings shall be enough machined to do the hydrostatic test. To secure the casting defect, all products shall be hydro - static tested by special hydro static test equipment. Test pressure shall be applied in accordance with standard specification or client requirement. 2nd Machining- Flange & Socket After finishing the hydrostatic test, the flange face & socket shall be fine machined in accordance with the standard specification. KXD shall machines all part of flange and socket with new modern model turning machines. Maximum production range is 1,600 mm diameter. The holes of flange bolt shall be bored in accordance with the standard specification or the client requirement. For the installation of the flange joint insulation kit, KXD will drill 2 mm over size comparing original bolt hole size in the standard specification, if required. After finishing machining & drilling hole, KXD will do 2nd hydrostatic test to secure the casting defect finally.2nd hydrostatic test will be randomly tested. Test pressure shall be applied in accordance with standard specification or client requirement. 12

13 The surface preparation for the coating shall be blast cleaned to achieve a near white surface conforming to Sa 2.5 of BS 7079: Part A The micro-profile range shall be set at 50~175 microns using G17~G24 steel grit. Before Fusion Bonded Epoxy(FBE) or Polyethylene(PE) coating, the surface temperature on Ductile Iron Fittings shall be monitored using a non-contact infrared thermometers. The surface temperature should be taken after coating to ensure that the temperature has not dropped to below the coating manufacturer's recommended lower temperature. Before the temperature drops on the surface of Ductile Iron Fittings, the Epoxy powder shall be applied by electrostatic spraying or flock spraying. A preliminary application of Fusion Bonded Epoxy powder to minor pinholes in the casting by palette knife will be used prior to spray application. After the application of Fusion Bonded Epoxy powder, the coating shall be cured at 170 ~210 for 20 ~ 35 minutes to increase adhesion in accordance with manufacturer's recommendation of the epoxy powder. After curing, the coating will be cooled down to 93 and below prior to testing. KXD will do final inspection as per Inspection Test Plan (ITP). Major Test Activities are ; Mechanical property test Hydrostatic test Coating holiday test Coating adhesion test Dimension check 13
