Pipe Ring Stiffness Testing Machine

Reason	Benefit
Designed specifically for pipe testing	More suitable than a general compression machine for large pipe samples
Accurate radial compression	Measures pipe stiffness and deformation behavior reliably
Computer-controlled system	Automatic test control, curve display, data recording, and report output
Supports multiple pipe materials	Works for PVC, HDPE, PP, GRP, and corrugated pipes
Large test space	Suitable for different pipe diameters depending on machine configuration
High precision load measurement	Helps ensure reliable QC and certification testing
Real-time curve display	Shows load vs deformation during testing
Automatic calculation	Software can calculate ring stiffness and test results
Useful for quality control	Confirms pipe strength before installation or shipment
Standard-compatible	Can be configured for ISO, ASTM, EN, and GB pipe testing standards
