Anchor Flanges

Product Overview

Anchor Flange Stockist & Supplier in India

Anchor flanges are specialized pipeline components designed to restrain axial movement and transfer forces from the pipeline to a supporting structure. As a reliable Anchor Flange Stockist in India and Anchor Flange Supplier in India, we supply anchor flanges manufactured for critical piping systems operating under pressure, temperature changes, and external mechanical loads.

An anchor flange is generally installed where pipeline expansion, contraction, thrust, or other axial forces must be controlled. The design is engineered according to pipe size, wall thickness, operating conditions, material grade, and project-specific load requirements.

With an established presence since 1985 and ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 certifications, Metal-Link supports anchor flange requirements with material traceability, inspection documentation and project-based supply.

Product Range

Different Types of Anchor Flanges

As an experienced Anchor Flange Supplier in India, we supply anchor flange assemblies for pipeline restraint, thermal expansion control, and axial load transfer in industrial and pipeline systems.

Welded Anchor Flange

Fixed Pipeline Restraint

A welded anchor flange is permanently attached to the pipeline and designed to transfer axial loads to the supporting civil or structural system. It is commonly used where pipeline movement caused by pressure thrust or thermal expansion must be restrained.

Typical applications include:

• ✓Long-distance pipelines
• ✓Process piping
• ✓Underground piping systems
• ✓Pump and compressor stations

Forged Anchor Flange

High-Strength Pipeline Connection

Forged anchor flanges are manufactured using forged materials to achieve suitable mechanical strength and structural integrity. The material is selected according to the connected pipe and the operating pressure and temperature.

Common materials include:

• ✓Carbon Steel
• ✓Alloy Steel
• ✓Stainless Steel
• ✓Duplex Steel
• ✓Nickel Alloy

Integral Anchor Flange

Combined Flange and Restraint Design

An integral anchor flange combines the connection flange with an anchoring arrangement designed to transmit pipeline loads. This configuration is useful where space, alignment, or structural load transfer requires a compact engineered solution.

Custom Fabricated Anchor Flange

Project-Specific Design

Custom anchor flanges are manufactured according to approved drawings and engineering requirements. Their dimensions may be designed based on pipe diameter, wall thickness, anchor load, flange rating, material grade, and installation arrangement.

High-Pressure Anchor Flange

Heavy-Duty Pipeline Restraint

High-pressure anchor flanges are designed for demanding service conditions where both pressure containment and axial load restraint are critical. They are commonly used in oil, gas, and petrochemical pipeline applications.

Insulated Anchor Flange

Electrical Isolation and Pipeline Protection

Insulated anchor flanges incorporate electrical isolation components to prevent galvanic corrosion and protect pipeline cathodic protection systems. They combine mechanical anchoring function with electrical isolation requirements.

Material Grades

Common Materials for Anchor Flanges

The material of an anchor flange is generally selected to ensure compatibility with the connected piping system and its operating conditions.

Design Data

Design Considerations for Anchor Flanges

Anchor flanges are engineered components and should be selected based on mechanical as well as pressure-related requirements.

Important Design Factors

Standards & Compliance

Standards and Specifications

Anchor flange assemblies may be designed and manufactured according to applicable piping, flange, material, and project specifications.

Project specifications and engineering calculations are particularly important because anchor flanges may be required to withstand significant axial loads.

Industry Use

Applications of Anchor Flanges

Anchor flanges are used in piping systems where controlled restraint is necessary to maintain pipeline stability and manage mechanical forces.

• ✓Oil and Gas Pipelines:
  Long-distance transmission pipelines requiring axial restraint at strategic locations to control expansion and pressure thrust.
• ✓Petrochemical Plants:
  Process piping systems where thermal expansion control and mechanical anchoring are critical.
• ✓Petroleum Refineries:
  High-temperature process piping requiring fixed anchor points for expansion loop design.
• ✓Power Plants:
  Steam piping, boiler connections, and thermal systems with significant temperature variations.
• ✓Pump Stations:
  Pipeline pump stations where pressure thrust and vibration require secure pipeline anchoring.
• ✓Compressor Stations:
  Gas compression facilities requiring pipeline restraint near compressor discharge and suction connections.
• ✓Underground Pipelines:
  Buried pipeline systems where thrust blocks or anchor flanges control axial movement at bends and fittings.
• ✓Water Transmission Systems:
  Large diameter water pipelines requiring anchoring at valve stations and elevation changes.
• ✓Chemical Processing Facilities:
  Corrosive service piping where both material compatibility and mechanical restraint are required.
• ✓Thermal Expansion Control Systems:
  Industrial piping systems utilizing expansion loops, expansion joints, or flexible connections requiring fixed anchor points.

Frequently Asked Questions

What is an anchor flange used for?

An anchor flange is used to restrain axial movement in a pipeline and transfer forces from the pipe to a supporting structure. It is commonly installed where pipeline expansion, contraction, pressure thrust, or other axial forces must be controlled to maintain system integrity and prevent damage to equipment or adjacent piping.

What types of anchor flanges do you supply?

We supply welded anchor flanges, forged anchor flanges, integral anchor flanges, custom fabricated anchor flanges, high-pressure anchor flanges, and insulated anchor flanges in various materials, sizes, and pressure ratings according to project requirements.

How is an anchor flange different from a regular flange?

A regular flange is primarily designed for pipeline connection and pressure containment. An anchor flange combines these functions with structural anchoring capability to resist axial loads, thermal expansion forces, and pressure thrust. It typically includes additional structural elements or attachment features to transfer pipeline loads to a support foundation.

What materials are anchor flanges available in?

Anchor flanges can be supplied in carbon steel (ASTM A105), alloy steel, stainless steel, duplex steel, and nickel alloys. The material is selected to match or be compatible with the connected pipeline material and service conditions including pressure, temperature, and corrosion environment.

What standards apply to anchor flanges?

Anchor flanges are manufactured according to applicable flange standards such as ASME B16.5 and ASME B16.47 for dimensions and pressure ratings. Design and installation must also comply with relevant piping codes including ASME B31.3 for process piping, ASME B31.4 for liquid pipelines, and ASME B31.8 for gas pipelines. Material specifications follow ASTM standards appropriate to the selected grade.

Can you supply custom anchor flanges according to project drawings?

Yes. We can supply custom fabricated anchor flanges manufactured according to approved engineering drawings and project-specific requirements. These can be designed for specific pipe sizes, wall thicknesses, anchor loads, flange ratings, material grades, and installation configurations. Material test certificates, dimensional inspection, and third-party inspection can be provided as required.
