Carbon Steel Anchor Flanges
Carbon Steel Anchor Flanges Manufacturer and Supplier in India
Carbon Steel Anchor Flanges are durable pipe fittings that restrict the axial motion and secure pipelines at certain anchor points. Different from ordinary flanges, which are typically used for assembling and sealing pipe ends, anchor flanges transmit the forces caused by pressure inside, thermal expansion, and pipe movement to a structural anchor made of concrete. Typically, these flanges are made of different types of carbon steel such as ASTM A105, A350 LF2, and A694. The applications of these flanges range from pipelines used in buried pipelines, pump stations, water supply pipelines, oil & gas pipelines as well as industrial pipelines. They are made according to project-specific sizes, ratings, and configuration, they can be manufactured based on relevant specifications and drawings. Solitaire Overseas is a leading Carbon Steel Anchor Flanges Manufacturer and Supplier in India.

Frequently Asked Questions
Carbon Steel Anchor Flanges are heavy-duty piping components used to secure pipelines and restrict unwanted axial movement.
They transfer pipeline forces, including pressure and thermal loads, to a supporting structure or concrete anchor.
They are welded or connected to the pipeline and anchored to a fixed structure, limiting axial movement caused by pressure or thermal expansion.
They are commonly installed at pipeline anchor points, pump stations, buried pipelines, water transmission systems, and industrial piping networks.
Yes, they can be used in high-pressure pipelines when the material grade, dimensions, pressure rating, and anchoring design meet the project requirements.
