It’s important to include an adequate supply of pipe supports – both quantity and style – in a fiberglass reinforced plastic (FRP) piping design.
For FRP piping systems, support spacing is closer than that of steel piping, yet farther apart than supports for thermoplastic piping. Refer to the specific technical bulletin of each piping system for recommended support spacing, or contact RPS Engineering for allowable support spans to ensure an adequate number of pipe supports are supplied.
The type of support to use for a specific application will depend upon a number of factors, the most important of which are the intended function of the support and the configuration of the available structural steel. The basic types of supports are weight supports, guides, and anchors. Various configurations of each of these types of supports are shown in the RPS Pipe Support Catalog, below.
In general, pipe supports for FRP piping will be wider and more robust than for metallic pipe in order to prevent points loads and keep the FRP pipe round. All supports (except flange supports) are lined with rubber to prevent chafing of the FRP. Refer to the RPS Design Manual for tips on choosing the right style of support, and for placement of supports away from elbows and buildups, and at heavy equipment such as valves.
Pipe supports and guides are critical elements of a FRP piping system design. Let us know how we can help bring your project to life.
