Interlocking micropile tubes

To meet the needs of certain applications, we also offer smooth tubes assembled using cylindrical or conical female sleeves machined in our workshops.

Steel Tubes and Profiles

To provide our customers with the resources they need to successfully complete their projects with as few contractors as possible, SOTOMET also offers all types of steel tubes and structural steel sections in a wide range of lengths and dimensions.

Stethoscope Tubes (NF P 94-160-1)

Our large, permanent inventory helps reduce our delivery times. Both the screw-on PVC caps and the snap-on polyethylene caps can be installed indoors or outdoors.

For this equipment designed for ultrasonic testing of foundations, we therefore offer two equipment solutions.

Smooth, flared tubes

These “seamless” pipes are joined using smooth, conical sleeves that are glued or welded together. This ensures a perfect seal, as well as quick and efficient installation.
