Mild steel sonic tubes for Cross Hole Sonic Logging (CSL) - the non-destructive pile integrity test used in ports, bridges, metro projects, and railway infrastructure.
Kridhan Sonic Tubes are Mild Steel ERW pipes manufactured for Cross Hole Sonic Logging (CSL) - the non-destructive testing method used to verify the integrity of cast-in-situ bored piles. Tubes are tied to the reinforcement cage before concreting, providing permanent access channels for ultrasonic probe insertion after the pile sets.
Each tube undergoes in-house pressure testing before dispatch to ensure zero slurry ingress. Available in three diameter variants (KST-50, KST-100, KST-150) to suit all standard bored pile sizes used in port, bridge, metro, and railway foundation work.
Three diameter variants to suit every bored pile specification - from congested small-diameter cages to large high-capacity foundation piles.
Standard-diameter tube designed for small-diameter piles with closely spaced reinforcement cages.
Standard diameter tube for smaller diameter piles and closely spaced cage reinforcement.
Mid-range diameter used in most standard bored pile applications across metro and bridge projects.
Large diameter tube for high-capacity piles requiring wider access for CSL probe insertion.
Each Kridhan Sonic Tube system ships as a complete kit - tube assembly, rubber gasket, and top cap - ready for immediate cage installation.
Complete tube unit with threaded couplers at both ends for seamless joint connection during installation.
Watertight rubber seal fitted at each threaded joint to prevent cement slurry ingress into the tube.
Protective cap fitted to the top open end of the tube after installation to prevent debris ingress.
Kridhan Sonic Tubes are engineered for fast site installation, zero-weld handling, and watertight integrity - minimising pile testing delays on your project schedule.
