Read MoreMaking continuous composite pipe
The continuous filament winding process was developed in the 1970s by Danish inventor Frede Hilmar Drostholm, and it was commercialized first by Toledo, Ohio-based Owens Corning’s engineered pipe systems business, in partnership with several entities, including Amiantit (Dammam, Saudi Arabia) and Vera Fabrikker (later Flowtite Pipe and Tank AS, Sandefjord, Norway). The ingenious process involves a cantilevered, horizontal rotating mandrel system.
