Steel Sonic Logging Pipe for CSL Pile Integrity Testing
Our steel sonic logging pipe is purpose‑built for Crosshole Sonic Logging (CSL) and other ultrasonic pile integrity tests. Manufactured from high‑strength carbon or stainless steel, each acoustic testing tube features a smooth internal bore and leak‑tight connections, guaranteeing reliable sound‑wave transmission in deep concrete pile foundations.
Key Features
Welded & Seamless Options – economical welded tubes or premium seamless pipes.
Smooth Bore – minimal signal attenuation for accurate CSL readings.
Corrosion‑Resistant Finish – galvanized or stainless surface for long‑term underground service.
Quick Installation – threaded, coupler or press‑fit joints save time on‑site.
Custom Sizes – diameters 50 / 54 / 57 mm; lengths up to 12 m.

Installation Guide
Fasten the steel sonic logging pipes to the reinforcement cage at the design spacing.
Connect sections using the selected coupler; seal the bottom with an end cap.
After concrete cure, flush the tube; ensure the ultrasonic probe passes freely.
FAQ
What is a sonic logging pipe?
A steel tube installed in a pile to form an access channel for ultrasonic probes used in CSL tests.
Is the pipe compatible with my CSL equipment?
Yes. Our inner diameter and straightness comply with global CSL standards and fit most probe sizes.
Need ultrasonic test equipment? We supply steel sonic logging pipes and can support CSL system integration on request.
