About this product
Product information from the supplier.
Product Overview
Dual Laminate FRP (Fiberglass Reinforced Plastic) represents the pinnacle of industrial material engineering, seamlessly merging the exceptional structural strength of FRP with the superior chemical resistance of a thermoplastic inner shell. By integrating these two high-performance materials, our dual laminate solutions provide a robust alternative to expensive metal alloys and rubber-lined steel, ensuring maximum durability in the most aggressive environments.
The manufacturing process involves thermoforming and welding a specialized thermoplastic liner, which is then chemically or mechanically bonded to the FRP exterior. This synergistic construction allows for a wide range of chemical compatibility and operating conditions, making these products indispensable for industries requiring high-performance containment and transport systems, such as chemical processing, pharmaceuticals, and offshore oil and gas.

Frequently Asked Questions
Q: What exactly is a Dual Laminate FRP product?
It is a composite material that combines a thermoplastic inner liner (for chemical resistance) with a fiberglass reinforced plastic (FRP) outer shell (for structural strength).
Q: How is the integrity of Dual Laminate tanks verified?
Conductive carbon ribbons are placed behind the weld lines, allowing the use of spark testing to detect any leaks or defects throughout the product's working life.
Q: In which industries are Dual Laminate products most commonly used?
They are widely used in chemical processing, food and beverage, pharmaceuticals, mining, environmental protection, and offshore oil and gas industries.
Q: Why choose Dual Laminate over standard steel products?
Dual laminate products offer superior corrosion and abrasion resistance, can handle higher temperatures, are significantly lighter, and do not suffer from external environmental corrosion.
Q: Can these products be manufactured on-site?
Yes, Jrain has the capability to supply a wide range of dual laminate products produced either in our professional workshop or directly at the customer's project site.
Q: What is the bonding strength between the liner and the FRP?
The adhesion between the thermoplastic liner and the FRP shell is engineered to be more than 7N/mm², ensuring structural stability under pressure.
