Recently, a batch of GRP (fiberglass reinforced plastic) tanks-specifically FRP backwash tanks used in the backwashing process-customized by our company for a large-scale water treatment project in Brazil, has been completed in our factory and has successfully entered the standardized packaging stage. They will soon be loaded into containers and shipped to the project site in Brazil. This export not only demonstrates our mature experience in the field of composite material pressure vessels but also showcases our factory's comprehensive strength in handling overseas orders from multiple perspectives, including production capacity, technology, quality control, international logistics, and after-sales service.
Large-Scale Production Ensures Efficient Delivery
This batch of fiberglass backwash tanks will be used in the pretreatment unit of a large-scale water treatment system in Brazil, undertaking critical tasks such as backwashing, filtration, and pressure stabilization. Due to the complex local water conditions and the hot and humid operating environment, the customer has placed extremely high demands on the tanks' corrosion resistance, pressure resistance, and service life. Our technical team, drawing on years of industry experience, utilizes high-quality acid and alkali resistant resins and high-strength alkali-free fiberglass yarn, employing a CNC winding process for integrated molding. This ensures a dense, leak-proof, and aging-resistant tank structure, fully meeting the long-term stable operation requirements of the Brazilian project.
Our factory boasts a modern fiberglass product manufacturing base, capable of handling multiple domestic and international custom orders simultaneously. Addressing the project's stringent requirements for tank wall thickness uniformity, inner surface smoothness, and a 1.0MPa pressure rating, our workshop employs fully automated CNC winding machines and a microcomputer-controlled curing system. This ensures precise control over the fiber winding angle, resin content, and curing curve for each GRP tank. Simultaneously, the application of large vertical machining centers and automatic cutting and trimming equipment ensures that the tank end face flatness error is controlled within ±1mm, providing a high-precision foundation for subsequent sealing assembly.
Strict quality control, verified by international standards
Our factory has established a seven-point quality inspection system from raw material intake to finished product delivery. The FRP backwash tanks used in this Brazil project are all made with high-quality acid and alkali resistant resin and alkali-free fiberglass yarn, and all batches undergo full inspection upon arrival at the factory. During production, each tank undergoes a hydrostatic test (holding pressure 1.5 times the working pressure), an airtightness test, and an endoscopic visual inspection to eliminate micro-cracks and air bubbles. Furthermore, our factory has passed ISO9001 and ISO14001 certifications, and our products meet international standards such as ASME and EN.
Professional Export Packaging
Considering the more than 40 days of sea freight and the high temperature and humidity unloading environment in Brazil, the packaging team reinforced the protection of each FRP backwash tank: the tank body is wrapped with moisture-proof pearl cotton and then fully sealed with a custom plastic film; plastic protective caps are added to the tank flanges to prevent damage to the threads and sealing surfaces.
Extensive Export Experience
Our company has provided GRP tank products to more than 30 countries and regions, covering water treatment, chemical, and seawater desalination fields. After the customer signs for the package, our after-sales team will provide a response service within 12 time zones and can arrange for engineers to provide remote installation guidance. We can also provide complete solutions from tank selection and pipeline interface customization to mass production, tailored to user needs.
This successful shipment not only demonstrates our manufacturing and delivery capabilities in the field of fiberglass pressure vessels but also further validates the competitiveness of customized fiberglass tanks in the overseas water treatment market. Domestic and international customers with similar project needs are welcome to contact us at any time.
