FRP Pressure Tank 1354 φ325×1400mm 2.5” Thread 2.0-2.5 T/H with Enhanced Curing

The FRP Pressure Tank 1354 stands out in industrial applications, boasting a diameter and height of φ325×1400mm, a 2.5” threaded top opening, and a design flow rate of 2.0～2.5 T/H. A key factor behind its reliability lies in its curing features, which significantly enhance performance.

Curing Characteristics

Curing of FRP can increase its strength by over 10%, and vacuum curing is one of the effective ways to boost the strength of FRP products. During manufacturing, some residual solvents and other low-molecular substances remain, which cannot be completely removed under normal pressure. These substances hinder the strong bonding between resin and glass fibers, thereby affecting the strength of FRP products.

The vacuum curing method allows low-molecular substances to volatilize more completely, making FRP products denser and thus improving container strength. However, it’s crucial that the curing agent in the binder is not easily volatile under reduced pressure. Otherwise, excessive volatilization loss of the curing agent will lead to incomplete curing of the product, which instead reduces strength.

Industrial Application Cases

• Desalination Plants: A coastal desalination facility uses the 1354 model in its high-pressure reverse osmosis system. Thanks to vacuum curing, the tank withstands 15bar operating pressure with 12% higher impact resistance than standard FRP tanks, reducing annual replacement costs by 25%.

• Chemical Transport: A hazardous chemical logistics company employs these tanks to transport corrosive solvents. The enhanced curing ensures leak-tight performance under road vibrations, complying with UN transport standards and lowering accident risks by 30%.
