What is an anchor flange?

What is anchor flange used for?

How to install an anchor flange to a pipeline?

[DSB123]

An anchor flange is a forged fitting used to prevent axial movement of a pipeline. It is normally cast in to a concrete foundation or drag anchor to limit/prevent pipe movement. Normally these are butt-welded into the pipeline and form part of the pipeline. They are specifically designed for the calculated pipeline loads.

is simple, using a drilled plate, and place it between the nut and the body of the flange. That plate buckling work will be welded to a base plate, and will be on this last plate where you do the fixed point. To prevent the bucking on the plate, you can use vertical plates between the two plates for prevent it.

You must not forget the sure need to include longer bolts for the flange.

Thank you very much!

I am trying to design a PLET(Pipeline End Termination).I want to use an anchor flange to fix the piping.

How do I design the anchor flange(based on the calculated pipeline loads)?

[DSB123]

If you get hold of the Taylor-Forge Guide this gives an example in there. Normally you provide the loads to a Supplier and let them supply a suitable flange.

Trukis,
What you advise is a "bodge-up". Better to provide a bespoke anchor flange capable of accommodating the loads rather than a Heath-Robinson design.

I recommend you without doubt, use a program of finite element calculation. FEPipe For me, the better.

If you do not have this program or any other finite elements, I recommend to you a manual calculation, with Roark's Formulas for Stress and Strain.

I include a standard support for your guide in the design :

For 2" to 8" :
