Product overview
Select by pipe data, operating duty and installation condition
Stainless steel pipe repair clamps provide a mechanical way to seal localized water-main defects such as pinholes, circumferential or longitudinal cracks and corrosion damage. They are often selected when a damaged section is otherwise suitable for repair and a full pipe replacement is not required.
The Conflex range of water pipe repair clamps includes stainless steel band clamps, mini repair clamps, connect repair clamps and repair clamp connectors. Among water pipe leak repair products, clamp OD range and sealing length must cover the complete defect and land on sound pipe surface.
Selecting a water pipe repair clamp requires more than DN. Every pipe leak repair clamp enquiry should provide the exact OD, pipe material, defect length and width, distance from joints, surface condition, working pressure, temperature and a clear site photo. The pipeline owner must also decide whether the pipe wall is structurally suitable for repair.

Installation summary
Five checks before commissioning
This summary does not replace the approved model drawing, torque table, project method statement or safety procedure.
Read the installation guide- 1Isolate and depressurize the line whenever the operator’s procedure requires it; verify that the pipe is structurally repairable.
- 2Measure the exact OD and defect, choose a clamp with adequate sealing length and clean the full gasket contact area.
- 3Centre the clamp over the defect and make sure the gasket is flat, unfolded and not sealing over an unsuitable overlap.
- 4Engage the bridge plate and fasteners correctly, then tighten nuts evenly from the centre outward in staged increments.
- 5Wait and re-check the specified torque where required; restore pressure under an approved procedure and inspect the repair.

Frequently asked questions
Repair Clamps FAQ
Can a repair clamp be installed while the pipe is under pressure?
Some clamp designs may support controlled live-line work, but the network operator’s safety procedure, pressure, defect and selected product must explicitly permit it.
How long should a pipe repair clamp be?
The gasket must extend beyond the complete defect onto sound, clean pipe surface. Send defect dimensions and photos so the required clamp length can be reviewed.
Which pipe materials can be repaired?
Documented products cover several steel, iron and plastic-pipe conditions. Exact compatibility depends on OD, surface profile, wall integrity and the selected clamp.
Is a clamp suitable for heavily corroded pipe?
A clamp seals a localized defect; it does not restore pipe-wall strength. Widespread or severe corrosion requires an engineering decision on replacement or a different repair system.
Need a dimensional table or model review?
Include the size range, standard, quantity and destination in your enquiry.
