Anchor Flange Definition:
An anchor flange is a device to restrain pipe movement in a piping system, it looks like a weld neck flange but has two hubs on the both sides to weld with the pipes, but there is no bolt bores on the anchor flanges.
Application of a anchor flange:
As we know, the steel piping system could move and shake when the liquid flowing through the pipe, especially when the piping system is turning in some places, the liquid will push the turning in the direction of liquids flowing. Another application of the anchor flange, there may bring expansion movements when temperature is changing in the piping system. Then an anchor flange is installed to combat the axial movement in the pipeline. The anchor flange is commonly secured into a concrete foundation. Besides preventing the axial movement, the anchor flange is also installed when the pipeline crossing from a bridge or river. Among this large distance, the pipe with huge liquid has the tendency to sag, if we use the anchor flange on the both sections of the pipeline, it will secure the position of the pipe.
How to install a anchor flange in piping system:
When we install a anchor flange in the chosen position solidly in a pipeline, we should weld the anchor flange with the two pipes first, then pour the concrete around the anchor flanges and the pipeline, the anchor flange should be sealed in the cement concrete. The anchor flange neck thickness and diameter should be same with the pipe dimensions for welding.
Material of the Anchor Flange:
The anchor flange is used to restrain and fasten the piping system, so the material of anchor flange should be in high strength. In our flange factory, the most common anchor flange material is SA105, ASTM A694 F52, F60 and F65 material is also recommended if necessary.
