Plastic fittings—ranging from couplings and elbows to tees and reducers—are critical junctions in piping systems. Testing these components guarantees leak-free connections, mechanical robustness, and compliance with pressure ratings under varied environmental conditions.
Essential Test Methods
Hydrostatic and Pneumatic Pressure Tests: Assess burst pressure, sustained-pressure endurance, and leak tightness at joint interfaces.
Pull-Out and Push-In Strength: Measure the force required to separate inserted fittings or slip-on connections, crucial for press-fit and push-fit systems.
Torque-to-Turn Tests: Determine actuation forces needed for threaded fittings, ensuring compatibility with manual or automated tightening tools.
Thermal Cycling: Repeatedly heat and cool assemblies to detect seal degradation and dimensional changes over daily or seasonal temperature swings.
System Specifications
Pressure Range: Up to 16 MPa, adjustable ramp rates for burst and endurance testing.
Force Measurement: Load cells with 0.2% accuracy for insertion and withdrawal forces up to 20 kN.
Temperature Control: Bath or chamber-based heating from 5 °C to 95 °C.
Data Logging: Continuous recording of pressure, force, temperature, and displacement with CSV or PDF export options.
Application Areas
Municipal Water Systems: Validating fittings in potable-water distribution networks.
Gas Piping: Verifying push-fit and electrofusion joints in PE and PP gas mains.
Irrigation and Agriculture: Testing fast-connect fittings used in drip and sprinkler systems.
HVAC and Plumbing: Ensuring solvent-weld and mechanical fittings meet pressure and leak-tightness requirements.
Professional Services
Customers benefit from adaptable test fixtures for non-standard sizes, integration guidance for automated test lines, and compliance consulting for regional standards such as ISO 16422 and EN 12266. On-site commissioning and user training round out the offering.
