Sonic testing tube , is a Push-Fit Solution dedicated for sonic test applications. They are specially designed to be encased in foundations such as bored piles, diaphragm walls and barrettes to allow for future testing of the concrete integrity by ultrasonic waves. Push-fit assemblyNo preparation off site No equipment required Easy & fast handing (5 times faster than traditional tubes)Easy fixing to rebar cage No weather limitations StandardOD (mm) Thickness(mm) tensile strength percentage of elongtation internal pressure external pressure Yhscg50×1-tc 50±1% 1±5% ≥315Mpa ≥14% ≥1 Mpa ≥4Mpa Yhscg50×1.2-tc 50±1% 1.2±5% ≥315Mpa ≥14% ≥1 Mpa ≥4Mpa Yhscg50×1.5-tc 50±1% 1.5±5% ≥315Mpa ≥14% ≥1 Mpa ≥4Mpa Yhscg50×1.8-tc 50±1% 1.8±5% ≥315Mpa ≥14% ≥1 Mpa ≥4Mpa Yhscg50×1-qy 50±1% 1±5% ≥315Mpa ≥14% ≥1 Mpa ≥4Mpa Yhscg50×1.2-qy 50±1% 1.2±5% ≥315Mpa ≥14% ≥1 Mpa ≥4Mpa Yhscg50×1.5-qy 50±1% 1.5±5% ≥315Mpa ≥14% ≥1 Mpa ≥4Mpa Yhscg50×1.8-qy 50±1% 1.8±5% ≥315Mpa ≥14% ≥1 Mpa ≥4Mpa
