Typically, PVC pipe is used for sodium hypochlorite service.
PVC pipe typically provides good service life for sodium hypochlorite.
PVC pipe is significantly less expensive than FRP composite pipe.
However, if there other circumstances that dictate the use of FRP pipe -such as its ability to handle mechanical abuse, higher pressures, long spans, etc. -you may want to consider the option of using FRP armored or overwrapped PVC pipes and fittings. We have built significant quantities of such FRP armored PVC pipe for similar services. This dual laminate combines the best of both worlds;
Using the PVC as the internal corrosion liner/barrier and the FRP as a structural portion of the wall.
The PVC inner pipe is a completely integral pipeline that handles the corrosive service Environment. We can provide not only the armored pipe, but al styles of pipe fittings and flanges with the FRP backing or structural laminate.
