Sweco Fab, Inc. recently designed and manufactured a 30,000 lb. Seawall Outfall Flow Regulating Device for a sea water outlet in Qatar. This 320 long flow conditioner is designed to allow water to flow through evenly. There are nineteen 16 FRP pipes inside an 84 diameter carbon steel pipe. The pipe bundle is secured within the 84 diameter shell pipe using spring washers, which keep the bundle tight and allows for differential expansion between the steel and FRP.
