Pipe sizes with a Nominal Diameter of 40 (1½”) and below in certain pipe classes can be isolated from the structural steel using a 10mm thick insulated pad with a U-bolt. Piping cannot be supported bare on the top of structural steel to avoid corrosion between a pipe and structural steel.Īll pipes should therefore be supported on pipe shoes. This will help protect both piping and connected equipment from excessive loadings due to thermal, weight, steelwork deflections, wind, earthquake, etc. Piping shall be adequately supported, anchored, or guided to prevent undue stresses, deflection, and excessive vibration. Prevent excessive heat flow to keep supporting elements’ temperature within their design limits.Maintain good thermal flexibility in pipeline.Avoid Resonance with imposed fluid-induced vibrations.Good support prevents excessive stresses in the supporting (or restraining) elements.
