タイトルまたは説明

Ultrasonic testing tube is the only specialized application for ultrasonic testing of a reliable system. This ultrasonic testing tube is to adopt fastener connection and concrete impervious connection to achieve a reliable anti-seepage effect with sonic logging.
Hooping ultrasonic testing tube finished products usually include the standard length of 9M, 6M, 3M steel tubes, a sealed steel apron and a fastener. And a channel can be reserved to enable detector have direct access to the bottom pile.

Hooping Ultrasonic Testing Tube
Technical Parameters Item: JT/T*******7 standards
Appearance: Inspect acoustic tube whether is of burr, cracks, scarring, folding, layer, welding defects, zoned road, abrasions, incorrect weld, burn, thin oxide with eyes and hand. Curvature is not more than 5mm/m.
