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.

Pipe and fittings inventory

RPS has an inventory of corrosion and abrasion resistant FRP pipe and fittings available for immediate purchase and delivery. We maintain stock in our Inspection, Distribution, and Service (IDS) Centers in Northeast US, the Gulf Coast, and Atlantic Canada, so you can have the reliability and performance of our pre-engineered pipe and fittings without the wait. With the help of our RPS Stock Tracker program, our IDS Centers can quickly find inventory that is closest to your site and can call on multiple RPS facilities to fill your order.

Let us know if you would prefer for us to ship it loose, sub-assemble it before shipment, or have our field services team bring it along with them to your site.
