A “revolutionary” new single-end glass roving reinforcement from Owens Corning, Toledo, Ohio, reportedly improves burst strength of high-pressure pipe by 17% and cyclical regression (stress) strength by 10%. The SE 2350 roving is for filament-wound epoxy pipe used for oil, chemicals, and other corrosive materials.
With this roving, pipe thickness can be reduced 10%, claims Owens Corning. SE 2350 also boosts manufacturing efficiency 41% and cuts rework 35% by providing easy and consistent delivery from creel to winding mandrel, plus less friction and fuzz. This eliminates broken strands and resulting defects. The roving also exhibits faster wet-out and has low, stable tension, which maintains uniform pipe construction with fewer stoppages to adjust tension.
