The GRP lining for water tank

Ensuring longevity, durability, and safety is crucial in the constantly evolving storage market. Water tanks supply safe water for many domestic and industrial uses. Various materials are available for tank design, but Glass-Reinforced Plastic (GRP) is an ideal choice, providing numerous advantages in water storage.

Oryx Fiberglass LLC, a famous company in Dubai, has established itself as the leader in providing GRP lining for water tanks.. With a dedication to high quality, innovation and customer satisfaction, Oryx Fiberglass has significantly contributed to transforming the way water storage is conducted across the region and even further.

Understanding GRP Lining

GRP lining is the addition of fiberglass-reinforced plastic to the exterior of water tanks. The composite material combines the durability of glass fibers with the flexibility of plastic resin, creating a flexible and light liner that is invulnerable to corrosion, leakage, and other external elements.

Benefits of GRP Lining for Water Tank

  1. Corrosion Resistance: One significant benefit of GRP-based linings is their exceptional resistance against corrosion. Contrary to conventional materials such as steel or concrete, GRP will not rust or damage itself when exposed to water or other chemical substances typically found within water.
  2. Protection from Leaks: The seamless installation of GRP lines creates a watertight seal that reduces the possibility of leaks and seepage. This is crucial for the containers that hold potable water, and contamination should be avoided at all costs.
  3. Durability: GRP liners are renowned for their longevity and durability. They can withstand extreme environmental conditions, including extreme temperatures, UV exposure, and mechanical stress, without compromising strength.
  4. GRP linings are lighter: Compared to other options like steel or concrete, GRP linings are less heavy and thus easy to move, handle, and set up. This saves time and money and offers more flexibility for tank designs and installations.
  5. Low maintenance: GRP lines require only minimal maintenance throughout their life. In contrast with conventional materials, which require regular inspections, repairs or coatings can function efficiently with only routine cleaning and regular inspection.

Applications of GRP Lining

GRP lining can be used for a variety of water storage needs that include:

  • Drinking Water Tanks: GRP liner linings ensure the quality and safety of drinking water by preventing contamination and ensuring the water quality standards.
  • Industrial Tanks: From wastewater treatment plants to storage tanks for chemical GRP linings, they offer secure and reliable protection against various chemicals and liquids, even in harsh environments.
  • Tanks for Agricultural Use: Farmers depend on tanks to water their crops, water livestock, and conduct farming processes. GRP linings are cost-effective and long-lasting solutions for these types of applications.
  • Tanks for fire protection: Fighting efforts rely on the reliability of water storage systems. GRP linings improve the performance and durability of tanks for fire protection, providing an abundant water supply during times of crisis.

GRP lining for water tank : Standard Procedures

Although the advantages of GRP linings on water tanks are obvious, achieving the best results requires adhering to standard and best methods. Oryx Fiberglass LLC follows a strict procedure to ensure the application’s success and efficiency of GRP-lined tanks. Here’s a brief overview of the typical techniques involved:

  1. Surface Preparation: Proper surface preparation is vital to ensure the bonding and efficiency of the GRP Lining. Oryx Fiberglass starts by sprucing up the internal area of the tank to eliminate debris, oil, or other contaminants. Depending on the material, this could include pressure washing, abrasive blasting, or chemical cleansing.
  2. Primer and Sealing: When the Surface is dry and clean, the bonding agent is used to ensure adhesion between it and the GRP liner. This step is vital to increasing the durability and strength of the liner system. Additionally, any voids, cracks, or defects within the substrate are sealed to prevent water from entering and ensure a smooth installation.
  3. Layering and Reinforcement: GRP lining is placed in layers, allowing for appropriate thickness and strength. Oryx Fiberglass combines fiberglass matting, resin and woven roving to form a rigid composite structure. The addition of reinforcement is possible in areas susceptible to structural or mechanical weakness, such as seams, corners, and holes.
  4. Curing and quality control: When the GRP liner is installed, it undergoes a curing process that allows the resin to set and bond to the substrate efficiently. Oryx Fiberglass carefully monitors the curing temperatures, humidity, and time to ensure the curing temperature is in the right circumstances. During curing, strict checks on the quality of products are in place to identify any flaws or irregularities that could affect the liner’s strength.
  5. The Surface is then finished and inspected: Once the GRP lining is cured, the Surface can be checked for uniformity, smoothness and compliance with specifications. If necessary, any air bubbles or inconsistencies are fixed by sanding, grinding, or applying additional coatings. The final finish of the Surface is determined by the client’s specifications and preferences, such as a smooth, glossy gel coat to enhance aesthetics or a non-slip finish to serve a purpose.
  6. Evaluation and Testing: Before the tank is put in service, comprehensive tests must be conducted to verify the performance and quality of the GRP liner. It could involve tests for hydrostatic pressure and leaks and chemical resistance tests to ensure they align with the industry’s standards and regulations. Once the testing is successful, the tank will be tested and certified, ensuring its safety and reliability.

With these standardized methods, Fiberglass ensures that every GRP lining installation meets the highest quality standards and provides long-lasting performance for water storage applications. From surface preparation to testing and certification, attention to minor details and accuracy are essential and reflect the company’s dedication to quality and customer satisfaction.
