Reliable Connection Solutions

High-strength ductile iron fittings designed for PVC pipe systems, combining corrosion resistance with mechanical durability for water transmission and industrial applications.
Product Features
Designed for seamless integration with PVC piping systems, these ductile iron fittings deliver reliable performance in water distribution networks. The push-on joint configuration enables rapid field assembly without specialized tooling, reducing installation time and labor costs. Flanged options provide secure connections for pump stations, valve installations, and equipment interfaces where dismantling access is required.
Material selection prioritizes corrosion protection through epoxy coating applied internally and externally, meeting drinking water safety requirements. The ductile iron substrate offers impact resistance and structural integrity under soil loading and pressure surges. Gasket materials including EPDM and NBR accommodate varying fluid temperatures and chemical exposure levels.
Flow characteristics remain consistent with pipe system hydraulics, minimizing pressure loss at connection points. Component interchangeability follows standardized dimensions, allowing straightforward integration with existing infrastructure. These fittings support both above-ground and buried installations across municipal and industrial projects.
Media Compatibility
Suitable for potable water, raw water, treated wastewater, and industrial process water. Chemical resistance varies by gasket material selection and coating specification.

Quality Assurance
Each fitting undergoes dimensional inspection prior to coating application to verify compliance with drawing specifications. Coating thickness measured using non-destructive methods on both internal and external surfaces to ensure minimum requirements are met. Hydrostatic pressure testing conducted on random samples per batch, following EN 12266 or equivalent procedures. Gasket material certificates provide traceability to raw material batches and confirm physical property compliance with ISO 4633. Third-party inspection services including SGS or BV can be arranged for project-specific quality assurance requirements. Factory test reports and material certificates provided with each shipment, with digital copies available upon request.
