HPPE MAXAR™ White PFA FRP Dual Laminate

MAXAR™ White PFA FRP piping liners are perfluoroalkoxy (PFA) Teflon® resin, seamless to 10″, and chemically inert to a broad range of commercial chemicals.

Considering all the dual laminate on the market, it’s our bonding layer that sets us apart. Our bonding technology eliminates air gaps between the PFA liner and the vinyl ester structure, thereby preventing condensation between the liner and structure, a common and costly problem in lined steel pipe. And all RPS dual laminates will provide excellent durability in corrosive environments, since the outer structural layer, FRP, is also corrosion resistant.

Choosing RPS dual laminate means longer life and lower lifecycle costs.

Quick Facts

PFA FRP pipe is suitable for all acids including hydrofluoric, hydrochloric, sulfuric, and aqua regia; all chlorides, sulfates, bleach solutions, solvents, caustics, phenols, peroxides, and more

INEOS DERAKANE™ 411 bisphenol A epoxy vinyl ester resin

Pressure Ranges: suitable for continuous operation from full vacuum to 150 PSI for 1½” through 12” diameter, and full vacuum to 100 PSI for 14” through 24” diameter.

Temperature Range: -5°F (-20°C) to 220°F (104°C). MAXAR™ piping systems with a continuous operating temperature above 180°F (82°C) should be evaluated by RPS Engineering to determine if the process conditions are acceptable.

Why Composites?

Advantages of Composite Piping

Composite tanks, vessels, and piping systems, both fiberglass reinforced plastic (FRP) and dual laminate (FRP with a thermoplastic liner) stand out as superior choices over many other construction materials including rubber lined carbon steel (RLCS), stainless steel (SS), alloys, and thermoplastics due to a combination of advantageous features and properties.

One of the primary benefits of composite piping is its exceptional resistance to corrosion. This makes it particularly valuable in industries where exposure to corrosive substances is common, such as chemical processing, power generation, and mineral processing. FRP and dual laminates are suitable for a wide range of process streams including hydrochloric acid, sulfuric acid, phosphoric acid, chlorine gas (wet and dry), chlorine dioxide, sodium hydroxide, sodium hypochlorite, solvent extraction solutions, brines, slurries, and more. In addition to the interior corrosion barrier, the exterior FRP shell is also corrosion-resistant, making it the material of choice in corrosive atmospheric conditions.

FRP piping systems offer an outstanding strength-to-weight ratio, combining strength and durability with a lightweight structure. Compared to materials like steel or concrete, FRP is significantly lighter, making it easier to transport, handle, install, and support. Lighter equipment could mean lower installation and maintenance costs.

FRP and dual laminate piping and tank liners typically feature a smooth interior surface. This smoothness minimizes friction and prevents the accumulation of deposits or scaling, which can lead to improved flow efficiency and reduced maintenance needs.

In addition to these features, FRP is a non-conductive material, making it suitable for applications where electrical conductivity is a concern. Composite piping is also highly customizable. It can be tailored to meet specific project requirements, including diameter, length, and special features like insulation, fire resistance, and abrasion resistance.
Low thermal conductivity is another benefit of FRP. It is most desirable in applications where maintaining temperature control or insulation is essential.

Thanks to its inherent resistance to corrosion and its long-term durability, FRP piping typically requires minimal maintenance compared to RLCS, SS, and alloys, which require regular, scheduled cleaning and coating to maintain corrosion resistance. While the initial cost may be higher than some other materials, the long-term advantages of FRP and dual laminate piping, i.e., reduced maintenance, longer service life, and corrosion resistance, along with the total cost of ownership, can make it the better choice for your operation.

Ultimately, the suitability of FRP piping depends on the specific application and environmental conditions. Careful consideration of project requirements and constraints is essential. Proper design, installation, and maintenance practices are also crucial to realizing the full benefits of FRP and dual laminate piping.
