PE300 Flange — Custom Wrap Clamp Covers the Flange and the Reducer

PE300 Flange — Custom Wrap Clamp Covers the Flange and the Reducer
The leaking PE300 flange joint, opened up for the repair.

This leak was not a plain flange: the PE300 flange bolted straight onto a reducing connection, so the failed area spanned both the bolt line and the taper behind it. A catalogue flange clamp sized for the flange alone would have left the second leak path exposed.

Flange and reducing connection enclosed together; the joint is sealed and the trench can be closed.

One part replaced what would otherwise have been a cut-out, a new flange and a new reducer. Both leak paths are now under the same steel shell, and the joint has been backfilled and put back into service.

Record

Site

Xuyi County, Huai'an, Jiangsu, China — Dongfang Avenue

System

PE300 main — flange onto a reducing connection

Condition

PE300 flange leaking at the bolt line; the joint also had a reducing connection immediately behind it, so a standard flange clamp would not have covered the leak.

Supply

Custom steel flange wrap repair clamp, extended to enclose the flange pair and the reducing connection in a single body.

Status

Both the flange and the reducer sealed under live pressure; the line was never drained.
