Sufficient space to be provided to facilitate support assembly installation, inspection, and maintenance.įig. ( it is applicable to straight run pipe length only.) When a change of direction in a horizontal plane occurs, it is suggested that the spacing be limited to ¾ times the standard pipe span. Always maintain the distance between supports as per project specification recommended support span table. Piping connected to the top of the vessel to be advantageously supported from the vessel to minimize relative movement between supports and piping. The use of hold down or similar supports offering resistance to motion and providing some damping capacity to be used rather than hanging type supports. Piping susceptible to vibration such as compressor connected lines to be supported independently. Supports to be located as near as possible to concentrated loads such as valves, flanges, heavy actuators, etc. 
Supports or braces to be located at or near neutral pts. grade or structure which is provided for other purposes.) Route lines close to the possible point of supports ( i.e. Group pipelines so as to minimize the number of structures needed solely to pipe supports. The following points need to be followed for optimized pipe supporting. 7: Primary vs Secondary Support Piping Support guide for Optimization 7) are the responsibility of the civil team.įig. The design and selection of secondary pipe supports (Fig. Support Brackets, Secondary Steel members on which pipe or primary supports rest, Tee Post, Goal Post, sleepers, racks, etc are examples of secondary pipe supports. Pipe supports that are not directly attached to the pipe are called secondary piping supports. 1) is the responsibility of the piping team. The design and selection of primary pipe support (Fig. For example, Shoe support, Clamp Support, Guide Support, Line Stop Support, Trunnion Support, etc. 
Pipe Supports that are directly attached to the pipe are called Primary pipe Supports. Piping Supports for Acoustic Insulation.All spring supports are locked during testing. it may be noted that during testing conditions there is no thermal load. Then to distribute the load uniformly, the number of supports should be provided with a smaller span.
Sometimes the line is capable of having a longer span but the load coming on the support may be very large (especially with large diameter pipelines). Supports should be designed for this load (unless otherwise decided in the project). In the case of the vapor line, this difference will be very large due to hydro testing. during operation as well as during testing. Pipe Supports are required to support the line during all conditions i.e.
The major purpose of pipe supports can be elaborated as follows: Piping Supports for Carrying Weights
to reduce excessive loading in support itselfįor the proper working of the piping system, it has to be supported properly. To redirect pipe thermal movements to the favourable direction. To limit undesirable line movements to protect sensitive equipment against overloading. To eliminate exposure of elements to temperature extremes, outside their design limit. To prevent excessive pipe sag (Normally more than 10 mm for process piping and 2.5 mm for power piping 12.5 mm for GRE/GRP piping). To remove unintentional disengagement (lift-off) of piping from its supports. To counter the undesirable effects of Seismic, wind, water hammer, slug, and other dynamic loadings. To prevent Pipe stresses in excess to allowable.
