3.Factory overview




Our FRP Pressure Tanks are designed to withstand high working pressures of 125PSI and 150PSI, making them suitable for various industrial applications. The tanks are manufactured using a combination of epoxy resin and glass fiber winding reinforcement, ensuring strength and durability. The liner of the FRP Filter Tank is made from food-grade PE raw material, which guarantees the safety and purity of the filtered water.
The manufacturing process involves blow molding/rotomolding integrated molding, which results in a seamless and leak-proof tank. The automatic CNC winding technology ensures precise and consistent winding, leading to a higher quality product. The tank mouth is available in threaded or flanged joints, providing flexibility in installation.
Our FRP Pressure Tanks have undergone rigorous testing and certification. They have passed NSF, CE, and ISO9001 certifications, ensuring compliance with international quality standards. The tanks have also been subjected to more than 100,000 fatigue tests, which is four times the burst pressure. This indicates their reliability and ability to withstand extreme conditions. With their high working pressures, durable construction, and certifications, they are a reliable choice for water treatment systems.
