The Advantages of FRP Tanks Over Polyethylene

Advantages of FRP Tanks

It’s a big decision to purchase a storage tank, chemical or otherwise, and it’s important to know what kind of tanks are right for your particular job. If you’re considering either a polyethylene tank or a fiberglass reinforced plastic tank, it’s important to recognize the differences in all aspects, including maintenance, cost, shipping, and longevity. Here’s what to keep in mind when you’re deciding between an FRP or a polyethylene storage tank.

FRP Tank

  • FRP tanks are meticulously manufactured in a very hands-on and laborious assembly of resin and filament layering and/or winding to construct the tank.
  • More expensive upfront because of the complicated construction process, but built to outlast competitors in harsh situations.
  • Easily customizable as accessories can be added to any part of the tanks’ surface rather than limited to flat areas.
  • FRP tanks are notoriously low maintenance because of their corrosion resistance and durability in the face of extreme environments.
  • The more intensive process of construction requires a longer build time for FRP tanks, but what you pay for in time spent waiting you get back in a long lifespan of the unit.
  • A more lightweight design that can be stacked or shipped together more easily.

Polyethylene Tank 

  • Poly tanks are produced in an automated production line and are constructed via a plastic welding method or roto-moulding process.
  • Less expensive due to less labour-intensive production and lower cost of materials.
  • Accessories and valves must be molded into the structure of the tank itself to prevent leaks.
  • Poly tanks are also low maintenance, but can be more difficult to repair as the valves and other pieces are a part of the overall structure of the tank. This can mean more replacements may be necessary.
  • Quicker construction time means you get the product faster.
  • Poly tanks can swell 3% – 4%, meaning the fittings need expansion joints to combat this which may increase the cost.
  • Are heavier overall and need to be carefully shipped, but are manufactured faster.

The decision between FRP or polyethylene tanks should come with a thorough understanding of the specifications of each tank and the requirements of your storage needs. Whether you work in the agricultural, chemical, oil and gas, potable or wastewater industries, a trustworthy and long lasting solution is the ideal storage option.
