Pipe anchor protecting equipment

[steve1]

I am a structural engineer who has been tasked with designing a slab on grade that will support a piece of mechanical equipment along with a pipe anchor. The mechanical enginer has stated that the anchor will support carbon steel pipe on one side and a flexible pipe on the other. The purpose of this anchor will be to protect the equipment from being loaded by the pipe reactions.

My question is: Is this an acceptable way to do this?

Without more details, I'd have to say YES.

When you say carbon steel pipe on one side and flexible pipe on the other, I assume you mean some sort of expansion joint. An expansion joint would be one of my last choices.

What I'd recommend is a flexible configuration of carbon steel piping between the anchor and the equipment if possible.

I often ask the Civil folks to include the foundation/pedistal for my first pipe support with the equipment foudation or at least on the same mat, especially on pumps. A design like this will allow any settlement that might occur to be the same for both the equipment and the first support.

Thanks for your reply NT. Yes they do mean flexible pipe between the anchor and the equipment. I assume the intention is to use some sort of braided(?) pipe. In the past in a similiar situation the piping engineer was adament that an expansion joint would not be used and instead a flexible run of pipe, such as you suggested was specified. My concern here is that the piping designer is "assuming" that the configuration will work, but I'm not sure that they "know" it will work. Of course all of this is outside my field of expertise so I'm just trying to ensure that what is specified will work since the anchor design will end up on my drawing.

Get the rigid pipe's anchor forces from the pipe stress engineer.
