Standard Piping Details

Publisher Summary The standard piping detail is a drawing that depicts an item or items that are used with such frequency and having consistency in their installation procedure that a single drawing can be created and duplicated for use to represent their installation in almost every situation. This chapter discusses the methods and devices used for the support, anchoring, guiding, and spacing of pipes. Arrangement and positioning are important factors in the layout of a piping facility. Therefore, proper spacing and arrangement of pipes in a pipe rack require special attention. A pipe rack has a defined width; therefore, working within the allotted space makes spacing crucial. Pipes should be arranged to take up a minimum amount of space, and allowances should be made for any pipes that might be added in the future. A major concern when arranging pipes in a rack is the amount of expansion and, to an extent, contraction that occurs when a cold pipe is heated to its normal operating temperature. Expansion is not the only force that can alter the alignment of a pipe. Vibration, commodity turbulence, and other external forces—such as wind—cause a pipe to move.
