Different Types of Induction Bends

As an experienced Induction Bend Supplier in India, we supply a complete range of induction bends for high-pressure pipelines, process piping, power plants, refineries, and custom-engineered applications in various materials, sizes, radii, and bend angles.

Long Radius Induction Bend

Smooth Flow and Reduced Pressure Loss

Long radius induction bends provide a gradual change in flow direction. The larger radius can help reduce turbulence and pressure losses compared with sharper directional changes.

They are commonly used in:

• ✓Oil and gas pipelines
• ✓Petrochemical plants
• ✓Water transmission systems
• ✓Process piping networks

Short Radius Induction Bend

Compact Design for Space-Restricted Applications

Short radius induction bends provide a more compact bending solution where installation space is limited. While they may result in higher pressure losses compared to long radius bends, they are essential for tight piping configurations.

Applications include:

• ✓Space-restricted piping layouts
• ✓Compact process units
• ✓Offshore platform piping
• ✓Industrial plant retrofits

3D and 5D Induction Bends

Radius-Based Bend Selection

The designation of an induction bend is generally based on its centreline radius in relation to the nominal pipe diameter.

A larger bend radius is generally selected when smoother flow characteristics, piggability, or reduced stress concentration is required.

Large Radius Induction Bend

Custom Radius for Transmission Pipelines

Large radius induction bends are manufactured with custom bend radii exceeding standard 3D or 5D configurations. These bends are particularly suitable for long-distance transmission pipelines, piggable systems, and applications where minimal flow disturbance is critical.

Custom Induction Bend

Project-Specific Pipe Bending Solutions

One of the main advantages of the induction bending process is its flexibility for producing non-standard radii and angles. Custom Induction Bends can be manufactured based on pipeline alignment, installation limitations, and engineering requirements.

Custom parameters may include:

• ✓Pipe diameter
• ✓Wall thickness
• ✓Bend radius
• ✓Bend angle
• ✓Material grade
• ✓Tangent length
• ✓Design pressure
• ✓Design temperature

Induction Bending Manufacturing Process

Controlled Localized Heating and Forming

During induction bending, a narrow section of the pipe is heated using an induction coil. The pipe is progressively advanced while controlled mechanical force forms the required bend radius.

The process provides flexibility in producing bends from larger pipe sizes and thicker wall sections that may not be practical with conventional cold bending methods.

Typical manufacturing controls include:

• ✓Material traceability
• ✓Controlled heating temperature
• ✓Bend radius monitoring
• ✓Wall thickness measurement
• ✓Ovality control
• ✓Heat treatment where required
• ✓Mechanical testing
• ✓Non-destructive testing
• ✓Dimensional inspection
• ✓Hardness testing
• ✓Material Test Certificates

With an established presence since 1985 and ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 certifications, Metal-Link supports consistent manufacturing quality. Documentation may include Material Test Certificates, dimensional inspection reports, mechanical test results, hardness test reports, NDT reports, and third-party inspection certificates.
