Earthing Jumper for Flanges and Pipe Grounding
An earthing jumper for flanges is used to provide electrical continuity between two metal pipe sections, flanges, or connected metal parts. In many industrial systems, pipelines, valves, flanges, pumps, tanks, and metal structures must be properly bonded and grounded to reduce potential differences and support electrical safety. A copper strip type flange earthing jumper is a simple but important component for these grounding and bonding applications.
Carsai Precision Parts manufactures custom copper earthing jumpers, flange earthing copper jumpers, copper jumpers for flanges, pipe flange grounding jumpers, flange grounding jumpers, pipe grounding jumpers, and earthing jumper patti products according to customers’ drawings, samples, hole spacing, length, width, thickness, and surface treatment requirements. These products are widely used in industrial plants, oil and gas facilities, chemical plants, power equipment, water treatment systems, electrical installations, and other projects where reliable metal bonding is required.

What Is an Earthing Jumper for Flanges?
An earthing jumper for flanges is a conductive connection installed across a flange joint or between two pipe sections. The purpose is to maintain electrical continuity across the connection point. In some pipe systems, gaskets, paint, coatings, corrosion, or loose mechanical contact may reduce conductivity between two metal parts. A flange earthing copper jumper helps create a direct conductive path.
This product may be called by different names in different markets, such as copper jumper for flanges, flange copper jumper, pipe flange grounding jumper, flange grounding jumper, copper strip type flange earthing jumper, or earthing jumper patti. Although the names are different, the function is similar: to connect two metal parts for grounding, bonding, or equipotential connection.
In many projects, the jumper is installed with bolts on both sides of the flange. The hole size and hole spacing must match the flange or installation point. The copper strip or flexible copper connector then bridges the joint and provides a stable electrical path.
Why Flanges Need Earthing Jumpers
A flange connection may look like a solid metal-to-metal connection, but it does not always guarantee good electrical continuity. Flanges may include non-metallic gaskets, paint layers, surface oxidation, sealing materials, or coatings. These factors can reduce conductivity between two pipe sections.
An earthing jumper for flanges helps solve this problem by creating an additional conductive bridge. This is especially important in systems where grounding continuity is required for safety, static control, lightning protection, or electrical bonding.
For example, in an oil and gas pipeline system, static electricity may build up during fluid movement. In chemical plants, pipe systems may need bonding to reduce potential differences between metal parts. In electrical installations, metal pipe and equipment structures may need to be connected to the grounding system. A copper jumper for flanges can support these requirements.
Common Types of Flange Earthing Copper Jumpers
Copper Strip Type Flange Earthing Jumper
A copper strip type flange earthing jumper is usually made from flat copper strip. It is simple, strong, and easy to install. The ends are drilled or punched with holes according to the required bolt size and flange hole spacing. This type is commonly used for pipe grounding and flange bonding.
Flexible Copper Flange Jumper
A flexible flange copper jumper can be made from copper braid, stranded copper, or flexible copper conductor. It is suitable for installations where vibration, movement, or alignment tolerance exists. Compared with a rigid copper strip, a flexible type can absorb slight movement and reduce mechanical stress.
Tinned Copper Earthing Jumper
A tinned copper earthing jumper has a tin-plated surface to improve oxidation resistance. It is often used in humid, outdoor, or industrial environments. Tin plating also helps keep the surface cleaner and more stable over time.
Earthing Jumper Patti
In some markets, especially India and nearby regions, a flat copper earthing strip may be called an earthing jumper patti. This usually refers to a copper strip or copper link used for grounding and bonding. Carsai can customize earthing jumper patti products with different lengths, widths, hole sizes, and surface finishes.
Applications of Pipe Flange Grounding Jumpers
Industrial Pipeline Systems
Industrial pipelines often include many flange joints, valves, and equipment connections. A pipe flange grounding jumper can be installed across flange joints to maintain continuity and reduce grounding risks.
Oil and Gas Facilities
Oil and gas systems may require bonding and grounding for static electricity control and electrical safety. Flange earthing copper jumpers are commonly used in pipeline systems, storage tanks, pumping stations, and related metal structures.
Chemical Plants
Chemical plants often use pipelines with coatings, gaskets, and different metal sections. A copper jumper for flanges can help maintain electrical continuity across these connections.
Power Plants and Electrical Facilities
Power equipment, metal piping, and support structures may require reliable grounding. Flange grounding jumpers and pipe grounding jumpers can be customized for these systems.
Water Treatment and Utility Systems
Water treatment plants and utility installations often include metal pipes, pumps, valves, and cabinets. Earthing jumpers can be used to bond these parts to the grounding network.
Building and Infrastructure Projects
In building electrical systems and infrastructure projects, metal pipe systems, cable trays, and equipment frames may require bonding connections. Copper earthing jumpers are commonly used because copper provides stable conductivity.
Material Options
Copper is the most common material for flange earthing jumpers because of its excellent electrical conductivity and good processing performance. Depending on the project requirements, the jumper can be made from:
- Bare copper strip
- Tinned copper strip
- Copper braid
- Tinned copper braid
- Copper foil
- Stranded copper conductor
- Copper terminal plates
A bare copper flange grounding jumper is suitable for many indoor or controlled environments. A tinned copper pipe grounding jumper is better for outdoor, humid, or corrosive environments where surface protection is more important.
The material thickness and width depend on the required current capacity, grounding requirement, mechanical strength, and installation condition. For custom projects, customers can provide drawings or technical requirements, and we can manufacture according to the specified design.
Surface Treatment Options
For flange earthing copper jumpers, the most common surface options are bare copper and tin-plated copper. Tin plating is often selected because it helps protect the copper surface from oxidation and improves long-term appearance.
Available surface treatments can include:
- Bare copper
- Tin plating
- Nickel plating if required
- Cleaning and anti-oxidation treatment
- Brushing or polishing
- Custom surface finish according to project requirements
For outdoor pipe grounding or industrial flange bonding, tinned copper is usually a good option. It provides better surface protection than bare copper and is more suitable for demanding environments.
Custom Design Details
A copper strip type flange earthing jumper must fit the installation point correctly. Even a small difference in hole spacing or hole diameter can make installation difficult. That is why custom design is important.
Carsai can customize the following details:
- Total length
- Width
- Thickness
- Hole diameter
- Hole spacing
- Number of holes
- End shape
- Copper strip or flexible braid structure
- Bare copper or tinned copper
- Tin plating thickness
- Bending shape if needed
- Packaging method
For example, a customer may need a short copper jumper for flanges with two mounting holes. Another customer may need a longer pipe flange grounding jumper with special hole spacing. Some customers may require a flexible braided structure to handle vibration, while others may prefer a flat copper patti for a simple bolted connection.
Rigid Strip vs Flexible Jumper for Flange Grounding
Both rigid copper strip and flexible copper jumpers can be used for flange grounding, but they are suitable for different conditions.
A rigid copper strip type flange earthing jumper is strong, simple, and cost-effective. It works well when the installation points are fixed and aligned.
A flexible flange grounding jumper is better when the pipe system may move slightly, vibrate, or have installation tolerance. The flexible design reduces stress on the mounting points and can improve long-term durability.
If the flange connection is fixed and does not move, a copper strip type jumper may be enough. If there is vibration, movement, or alignment difference, a flexible copper braid jumper may be more suitable.

Quality Control
For copper earthing jumpers, quality control focuses on material, dimensions, hole position, surface finish, plating quality, and overall appearance. Hole size and spacing must match the drawing because these parts are usually installed directly with bolts on pipe flanges or metal structures.
For tinned copper jumpers, the plating surface should be clean and even. For flexible types, the braid or conductor should be properly pressed and firmly connected to the terminal area. For flat copper patti products, the edges and holes should be clean and suitable for installation.
Reliable quality is important because these products are used in grounding and bonding systems. A stable flange earthing copper jumper helps maintain electrical continuity and supports long-term system reliability.
