There are several different acceptable methods to join FRP piping together, all unique and with their own benefits and drawbacks. Many plants unfortunately are well aware of the drawbacks.
In this presentation by our Technical Director, Darryl Mikulec, we clearly outline best practices for butt-and-strap joints, bell-and-spigot joints, and flanged connections to prevent joint leaks, delamination, and premature failure in process piping.
Proper surface preparation, secondary lamination, resin curing, and laminator training are crucial to building reliable, leak-free FRP joints.
