Snubber support provided by an element composed of a nonlinear, damping element category d. The type of flange to be used for a piping application depends, mainly, on the required strength for the flanged joint. Analyze thermal movement, stress and flexibility of the piping system. The most common types of rigid supports are shoe type with clamp, shoe type welded, valve holder, and support brackets secondary support. Hanger type or bottom support type is selected based on pipe layout and the space availability for mounting. The spring support is designed to support piping from below, directly from the floor or supporting steel. The four main functions of a pipe support are to anchor, guide, absorb shock, and support a specified load.
