Buried Elbow — Moulded Steel Elbow Clamp Covers the Bend

Buried Elbow — Moulded Steel Elbow Clamp Covers the Bend
The buried elbow, exposed and measured before the clamp was made.

A leaking elbow is awkward for two reasons: the leak sits on a curve, which a straight clamp cannot follow, and replacing the bend means cutting the pipe twice, re-aligning the run and rebuilding the thrust restraint behind it.

The elbow clamp is fitted around the bend.

The elbow is measured on site — outside diameter and bend angle — and the clamp is formed to that geometry. It wraps the curve in two halves and closes on the bend itself, so the pipe alignment and the thrust block are left untouched.

The elbow is fully wrapped and sealed; backfill can follow.

The bend is sealed without ever being cut. Repairs like this are usually measured in hours, and the operator keeps the original pipeline geometry intact.
