They are used to restrain or limit main line thermal expansion or contraction and transfer built-up stresses to
external structures or larger foundation.
Anchor flanges can be installed in many different ways, such as suction and discharge laterals of pumping station
at river crossing, points of directional change, connections to equipment at meter run and to secure subsea piping and
risers to platform structure.
The flanges are supplied with end weld bevels to match the pipeline wall thickness.
The most common materials for anchor flanges are SA 105 and high-yield stress such as SA 694, F52, F60, F65 and F70.
Size range can cover up to 42”.
Each anchor flange needs a specific design and calculation in according to ASME VIII Div.1 and to process datasheet supplied by the customer.
Ordering information:
- Pipeline wall thickness
- Design code
- Design temperature
- Installation temperature
- Maximum axial load
HT pipe is able to calculate the flange dimensions and to manufacture them in many materials,
such as carbon steel, stainless steel and high-yield stress material.
