Ring Stiffness Tester for Corrugated and Solid Wall Pipes

Compression frame that measures the ring stiffness of buried drainage and sewer pipes by deflecting a pipe ring to 3 percent. Used by manufacturers of corrugated and structured-wall pipes.

Specification

A pipe section is loaded between parallel plates at a constant speed, and force at 3 percent deflection is used to determine ring stiffness in kN/m2. Sizes up to 1000 mm can be tested. The machine includes laser measurement of the pipe diameter and a computer for results.

Features

• Capacity 50 kN
• Plate length 500 mm to 1000 mm
• Automatic deflection control
• Pipe diameters 100 - 1000 mm
• Software with SN class reports
