1.0INTRODUCTION:
The arrangement of piping is probably the most important consideration affecting the layout of petroleum, petrochemical and similar types of plants. The following in general, is the order of importance in which piping systems should be considered. • • • • • Alloy piping or special materials Large bore piping or lined pipe. Low temperature pipe or other piping requiring thick andexpensive insulation. Major headers for utilities or auxiliaries. The routing of lines involving temperature where expansion and contraction necessitates flexibility which should preferably be inherent in the layout. Pipe shall be arranged in an orderly manner and routed as direct as possible.

PIPING STUDIES:
After a basic equipment layout has been developed, piping study drawings shallbe made for units which have sufficient size and scope to warrant further investigation of equipment arrangements, pipe rack widths and the like. For units or areas which obviously do not require extensive study due to simplicity of piping involved, the piping layout may be started directly which will eventually be issued as construction drawings. Responsibility for determining whether studydrawings are required and the extent to which they are to be carried, shall rest with Project Piping Engineer. The study drawings are intended to serve the following purposes: • • • • • To confirm equipment locations for review, comments and/or early approval by various concerned departments on the plant layout. As a basic guide to making model, constructions drawings and isometrics. To help minimizeinterferences by showing the structural, instrumentation and electrical groups the intended piping and equipment arrangements. To enable the analysis of line expansions and supporting systems. To enable other concerned departments i.e. Pressure vessel, Civil, Structural, Electrical, Heat Exchanger, Process Departments to develop their work/check their requirements.
In general, study drawingsconsist of plans, elevations (where necessary) showing unit piping arrangement fulfilling all conditions laid down in P&ID manifold locations, platform, elevations, instrumentation etc. And schematic routing diagram of piping piping on the racks. They will also indicate special requirements like monorails for exchanger bundle pulling or catalyst loading etc. Piping Studies are prepared as linediagrams to form the basis of General Arrangement Drawings and the details shown in the case of piping general arrangement drawings for construction are not shown to that extent such as control valve manifolds are shown as a block, only important elevations and arrangements are shown etc.

THERMAL EXPANSION: Arrangement shall provide for flexibility of lines to take care of thermal expansion and contraction. Large reactions or moments at equipment connection shall be avoided.

CRITICAL PIPING: Where dynamic loading, limited pressure drop, or other severe service conditions apply, particular care be taken while routing the piping. DYNAMIC LOADING • Dynamic loading...
