Designed to seal test pipes securely with durable seal rings and metal rings for accurate testing results.
Range of Application
This specialized assembly is purpose-built for sealing and encapsulating pipe specimens including PVC, PE, PP-R, ABS, and composite pipes. It serves as a critical component for validations such as:
Hydrostatic pressure testing
Burst testing
Negative pressure testing
Other pipe performance assessment protocols
Featuring a semi-circular pot structural design, it delivers streamlined installation, hermetic leak-tight sealing, and intuitive operation—ensuring consistent, stable sealing integrity throughout the entire test cycle.
Available in custom diameter configurations tailored to individual specifications, with material options including 304 stainless steel and carbon steel for superior durability and compatibility.
Working Principle
End caps function as the core sealing components for pipe test specimens. High-temperature-resistant silicone sealing rings are pre-embedded in dedicated seal grooves, while integrated metal rings apply uniform compression to these silicone rings.
The O-ring achieves reliable sealing via elastic deformation induced by external compressive force, securing consistent sealing integrity throughout the test cycle.
Configuration
Delivered as a fully pre-assembled unit including bolts, O-rings, vent valves, and all associated functional parts—eliminating on-site assembly efforts.
Fixture Structure
The semi-circular pot-type design ensures streamlined installation, hermetic leak-proof performance, and intuitive operational handling for reliable sealing throughout all pipe test cycles.
