Locate anchors to force thermal growth and displacements away from sensitive equipment and towards areas where movement will have no adverse affects, usually towards areas that do not have equipment. Especially avoid anchoring points where such may foster pipe forming local lever actions by taking lateral forces on one end and transferring them across the lever point to amplify those forces on equipment located on the other side of the anchor. Try to locate anchors where they will introduce beam bending for axial force. Beam bending is inherently more flexible than axial displacements, resulting in less reaction from bending loads than you would get from axial anchoring.
While you are doing that, try to remember that every anchor added will reduce deflection and movement, but at the cost of increasing internal stress and resultant forces on anything trying to restrain the pipe so anchored. Basically with the placement of anchors you are trading reduced movement for increased stress, or v/v.
