Bronze Pipe Clamps for Grounding
Cable Glands India manufactures Bronze Pipe Clamps for Grounding, used to bond earth conductors to metallic water pipes, structural pipe columns, casing pipes, and process pipework as part of a facility earthing and bonding scheme. These clamps wrap fully or partially around the pipe circumference, providing a secure mechanical grip and full-contact electrical bond regardless of pipe diameter or surface curvature. Electrical contractors, industrial plant engineers, and utility maintenance teams specify bronze pipe clamps wherever a round pipe, rather than a flat tape or rod, forms the bonding point in an earthing or equipotential bonding network.

Product Overview
Function of Pipe Clamps in Earthing and Bonding
A pipe clamp bonds an earth conductor or bonding jumper to a metallic pipe, ensuring the pipe is held at the same electrical potential as the rest of the earthing network. This is required both for personnel safety, where a metallic water or gas pipe could otherwise become energised during a fault, and for corrosion control, where consistent bonding limits stray current effects on buried pipework.
Bronze Construction and Corrosion Resistance
Our pipe clamps are manufactured from C83600 and C95400 bronze alloys, chosen for their combination of electrical conductivity and long-term corrosion resistance in damp plant rooms, buried pits, and outdoor pipe runs where the clamp cannot be easily inspected or replaced.
Adjustable Band Clamp Variant
The adjustable band clamp uses a curved bronze band with a tightening mechanism, allowing a single clamp size to accommodate a range of pipe diameters, which simplifies stocking for contractors working across multiple pipe sizes on a site.
Fixed Diameter Clamp Variant
Fixed diameter clamps are cast to match a specific standard pipe outer diameter precisely, providing maximum contact area and clamping force for permanent, high-integrity bonding points on critical process or utility pipework.
Split Clamp Variant for Existing Pipework
Split, two-piece clamp designs allow installation around an existing pipe without disconnecting or cutting the pipe run, which is particularly useful for retrofitting earthing bonds onto live water, gas, or process piping.
Terminal Lug Integration
Most pipe clamps are supplied with an integrated terminal lug or stud, allowing a bonding conductor to be bolted directly to the clamp without requiring a separate connector, reducing the number of joints in the bonding path.
Bimetallic Considerations
Where the pipe material is steel, galvanized steel, or aluminum, tin-plated bronze clamp bodies or bimetallic isolation washers are available to minimise galvanic corrosion risk at the clamp-to-pipe interface.
Key Features
- Adjustable band and fixed diameter clamp designs
- Cast bronze body for long-term corrosion resistance
- Split clamp option for installation on existing pipework
- Integrated terminal lug for direct conductor bonding
- Suitable for water, gas, process, and structural pipe bonding
- Compliant with IS 3043 and IEC 62561 earthing standards
Full-Circumference Contact
Band-style clamps distribute clamping force around a greater portion of the pipe circumference than a simple bolt-on lug, improving contact stability on pipes subject to vibration or thermal expansion.
Corrosion Performance on Buried and Damp Pipework
Bronze construction resists the corrosion that quickly degrades plated steel clamps in damp trenches, pits, and plant rooms, maintaining a reliable bonding connection over decades of service.
Retrofit Installation Without Pipe Cutting
Split clamp designs allow bonding to be added to existing, already-installed pipework without shutting down or cutting the pipe run, reducing installation disruption on active facilities.
Compatibility Across Pipe Materials
Pipe clamps are suitable for bonding to steel, galvanized steel, cast iron, and copper pipework, with bimetallic protection options available where dissimilar metal contact is a concern.
Reduced Joint Count
Integrated terminal lugs eliminate the need for a separate connector between the clamp and the bonding conductor, reducing the number of mechanical joints and associated resistance points in the bonding path.
Long Service Life
Correctly installed bronze pipe clamps require minimal maintenance and typically remain serviceable for the full operational life of the pipework they bond.

Applications in Industry
Water Service Pipe Bonding
Electrical contractors use pipe clamps to bond incoming metallic water service pipes to the building main earthing terminal as required by national wiring regulations.
Industrial Process Piping
Process plants use pipe clamps to bond pipe racks and process pipework into the plant earthing and static discharge network, particularly in areas handling flammable materials.
Substation and Utility Pipework
Utilities use pipe clamps to bond cooling water pipes, gas pipes, and structural pipe supports within substations to the station earth grid.
Cathodic Protection and Stray Current Control
Pipe clamps provide defined bonding points used in cathodic protection testing and stray current mitigation schemes on buried metallic pipelines.
Commercial and Residential Building Earthing
Building services engineers use pipe clamps to bond structural steel pipe columns, HVAC pipework, and plumbing systems into the overall building earthing scheme.
