STROMEN specializes in large-diameter, export-quality FRP pressure vessels for demanding, high-volume industrial applications like water treatment and chemical storage. Our vessels, built using precision filament winding, are a superior, cost-effective alternative to steel, offering unmatched corrosion resistance and exceptional strength for critical fluid management.
STROMEN Large Diameter vessels are manufactured via filament winding, starting with the application of a corrosion-resistant inner liner. Resin-saturated fiberglass is precisely wound onto this liner in controlled Hoop and Helical layers for optimal strength. The structure is then cured and fitted with accessories like hand holes and nozzles. The final product undergoes rigorous hydro testing to certify export quality and unmatched performance.
