Cost & Time Savings
The PE Flex Plus pipe provides major advantages over conventional poly pipe and its permeation short-falls.
While conventional polypipe by itself provides the industry with a solution to internal and external corrosion over steel pipes, it still suffers from a vulnerability to chemical permeation. In the instances of polyethylene, gas and liquid hydrocarbon compounds will eventually be driven into and through the plastic pipe wall by the pressures and temperatures inside. This process expands, weakening the pipe, making it more susceptible to permeation and leading to early-life failure. Additional issues can exacerbate permeation rates such as the density of the pipe, the pressure differential between the inside and outside of the pipe, temperature, available surface area and the type and volume of hydrocarbon compound in question.
However, designed for ultra low permeation, the PE Flex Plus’s three layers provide cost and time savings over the five layers of our flagship product, Thermoflex Pipe. With fewer layers, the PE Flex Plus pipe still provides protection against permeation but additionally allows for quicker installs thanks to spools consisting of longer continuous lengths.
But Can It Still Protect Against Permeation?
Built for hydrocarbon and paraffin resistance, PE Flex Plus is ideal for low-pressure fluid transport below 300 psi while still servicing highly corrosive environments. The fully piggable PE Flex Plus pipe can safely transport oil (including hot oil), gas, saltwater, brine CO2, H2S and condensate.
The unique design of the PE Flex Plus pipe features an inner nylon PA6 liner that protects against ultra-low hydrocarbon permeation. Even though it is an industry standard to de-rate by 50 percent any HDPE system that is designed to accommodate more than a two-percent content of liquid hydrocarbons, the PE Flex Plus requires no pressure derating for hydrocarbons. The Standard Polyethene temperature derate curve should be honored.
When Temperature Matters
The maximum operating temperature of the PE Flex Plus pipe is 140F. Working with higher temperatures? The PE Flex Plus RT pipe transports fluids up to 180F. PE Flex Plus RT features all the benefits of our PE Flex Plus pipe, plus a nylon liner with a PE-RT base to withstand higher temperatures.
Don’t Forget To Accessorize
The PE Flex Plus pipe offers two coupling options.
With 10-times faster installation in any weather, this reliable method requires no special tools or extra time for heating or cooling. It’s suitable for new, used, or dirty pipe, providing connections that meet or exceed pipe pressure ratings.
Featuring a lower per-unit cost, this method joins pipes by melting surfaces together. Suitable for all fluid types, it offers GPS traceability, superior corrosion resistance, and fusion consistency with no loss of pipe ID or joint strength.
