RPS Composites (Franklin, Ohio, U.S.) announces the availability of the newly engineered RPS Grooved Adapter to be used in conjunction with RPS fiber-reinforced polymer (FRP) piping systems and a Victaulic Style 296-A coupling to create a robust, reliable FRP piping joint.

According to RPS, ease of use is the Grooved Adaptor’s most attractive characteristic, as it can be coupled or uncoupled in a matter of minutes with no special tools or training. The RPS Grooved Adapter is designed for mildly corrosive environments including water, seawater, wastewater and some FGD services, up to 180°F and 150 psi (10 bar at 82°C). It is designed for the corrosion-resistant P-150 piping system as well as the corrosion and abrasion resistant A-150 piping system.

RPS FRP adapters have been tested and comply with ASME NM.2-2020 Proof of Design qualification test requirements, which include a series of hydrostatic strength, static pressure and cyclic pressure tests. The adapters have also been tested in a pipe bending test to demonstrate a factor of safety of no less than 6 in bending, with a coincident pressure of 150 psi.

Up until now, customers could choose to join their piping systems via the more traditional butt and wrap joint, the tapered adhesive joint, the bell and spigot O-ring joint and by a variety of flange options, dependent upon chemical media, pressure, pipe diameter, liner thickness and skill level of installation labor. The RPS Grooved Adapter joining system adds to these available options; it is available in 2-12" diameters.
