The service encompasses melting and casting ductile iron components to withstand extreme operating pressures and dynamic fluid loads:
▪ Metallurgical optimization of chemical composition ensuring superior mechanical ductility and tensile resilience.
▪ Advanced sand molding procedures guaranteeing dimensional accuracy and complete structural homogeneity free from internal porosity.
▪ Custom casting tailored for heavy municipal water, sewer, and high-spec industrial fire systems.
Utilizing advanced turning lathes and computerized CNC machining centers to satisfy strict engineering drawings:
▪ Flange facing, inside/outside diameter turning, wall thickness calibration, and precise chamfering.
▪ High-speed automated CNC milling executing complex geometries within a single setup to eliminate dimensional deviations.
▪ Multi-spindle drilling and tapping utilizing custom jigs ensuring 100% adherence to Pitch Circle Diameter (PCD) bolt patterns.
Castings are blasted with high-grade steel shot within enclosed automated chambers:
▪ Full elimination of oxidation, scale, foundry sand remnants, and surface contaminants.
▪ Attainment of international surface cleanliness standards in compliance with ISO 8501-1.
▪ Establishing the optimum surface roughness profile essential for durable chemical adhesion of polymer coatings.
The FBE coating service is conducted through an automated, tightly monitored four-stage thermal cycle:
▪ Preheating: Raising component temperature in controlled convection ovens above 210°C.
▪ Electrostatic Powder Application: Uniform spray application of certified drinking-water-grade epoxy powder (WRAS-approved).
▪ Thermal Curing: Controlled cross-linking ensuring complete polymer cohesion, chemical resistance, and high impact strength.
▪ Non-Destructive Quality Verification: Magnetic gauge verification of Dry Film Thickness (DFT exceeding 200 microns) and 100% high-voltage Holiday Testing to detect any microscopic pinholes.
Executed by trained assembly technicians on specialized product lines:
▪ Assembling resilient EPDM-encapsulated wedges, stainless steel stems, packing seals, and multi-layered O-ring seals.
▪ Calibrated torque tightening of body-to-bonnet fasteners to prevent local stress concentration and assure zero leakage.
▪ Mounting and calibrating manual gearboxes, electric multi-turn actuators, and limit switch signaling devices.
Conducted on dedicated hydraulic test benches in accordance with EN 12266-1, EN 1074, and ISO 2531:
▪ Shell Strength Test: Water pressure applied at 1.5 times the nominal working pressure (1.5x PN) to verify casting integrity.
▪ Seat Tightness Test: Water pressure applied at 1.1 times the nominal working pressure (1.1x PN) to ensure 100% bi-directional bubble-tight shutoff.
▪ Formal issuance of authenticated Factory Acceptance Test Certificates and inspection documentation
Supported by calibrated in-house quality laboratories and inspection equipment:
▪ Optical emission spectrometry for raw material chemical composition validation.
▪ Tensile, elongation, and Brinell hardness testing of metal test bars.
▪ Calibrated dimensional metrology following ISO 9001 governance protocols.
▪ Review and issuance of Material Test Certificates (MTCs Type 3.1) and Certificates of Conformity (COC).
A structured operational workflow providing:
