A pipe support is essentially a simplified structural framework that is required to support one or more pipes at an elevation with respect to the ground level. Various types of pipe supports are in use in the oil & gas industry, such as ‘T’, inverted ‘L’, ‘goal post’, ‘hanger’ & ‘bracket’. Pipes at lower elevations are directly supported on pedestals.
Friction between pipe and the steel beam induces lateral and longitudinal forces on supporting pedestals. Pedestals and footings are, therefore, required to be designed for bending in both orthogonal directions.
With portal frames, columns are often required to be oriented in such a way that the greater section modulus is utilised for bending perpendicular to frame plane.
