Sewage Storage Tank

Wastewater can be extremely aggressive towards a range of different tank materials, including concrete, steel, and even stainless steel. The content of sewage water not only varies from location to location but often varies from time to time. High hydrogen sulfide levels can be extremely aggressive, especially above the vapor line in storage and process tanks. Elevated chloride levels, as well as low and high pH, are also common immersion conditions in raw sewage. Ensure that your assets are appropriately protected, structurally sound, safe, and effective in the long run by talking with our experts. We can assist with inspections and spot repairs to structurally certified repair options for severely damaged tanks.

Water Treatment Tanks

Demineralization units are critical components of thermal power generation facilities. Often requiring both strong acids and strong bases, these systems are very aggressive towards most coatings, composites, steel, and concrete. We design proven solutions for every part of your water treatment process, including materials that are compatible with immersion in 98% sulfuric acid and neutralization basins. Allow our team to help protect your tanks, pumps, pipes, and secondary containment.

Tank Bottom Repairs

Many hydrocarbon storage tanks, especially crude oil storage tanks, are prone to corrosion on the floor and at the floor to wall joint if any trace water is present. Composite reinforcement solutions will not only prevent further corrosion but will structurally reinforce the floor and floor to wall joint to ensure continued operation of your tank. Our repair solutions are compatible with API 652, and you can use a modified ultrasonic technique to verify the composite integrity and even measure the steel wall thickness right through the composite. Contact our team to discuss a long-term solution for your tank bottoms.

Slurry Tanks

Slurry tanks, especially agitated slurry tanks, are especially erosive and can quickly wear away traditional coatings. Advanced FRP Systems offers a wide range of solutions ranging from abrasion resistant composites to fully structural reinforcement for even the most badly damaged tanks. Many tanks only require repair and reinforcement in specific high-wear areas. Our experts can help you diagnose issues with corrosion and erosion and prescribe the best, customized solution to enhance the life and reliability of your tanks.

A composite patch repair is widely used in the repair of metal and composite parts including pipes, tanks, beams, plates, and pressurized vessels.

A composite patch consists of reinforcing fabric and a resin binder. Composite repairs are performed on damaged steel pipes and tanks, composite laminate structures, fiber-reinforced composites, concrete, and other metallic substrates. The patch is placed over the damaged area after proper surface preparation to ensure adequate adhesion. The patch will prevent leakage, stop further corrosion and provide local strengthening to the patch area.

Small cracks and pinholes within the tank can successfully be repaired using a composite patch repair. To ensure crack growth or propagation does not continue under the composite patch, a crack should always be removed or properly terminated.

A repair patch made of carbon fiber and an immersion grade epoxy is not just a temporary repair; due to its high adhesion strength, outstanding tensile strength, and resistance to many aggressive chemicals, a composite repair patch can provide 20 years of structural health to the repaired tank.
