You spoke, and we listened.

You told us you wanted the ability to switch out sections of lined steel or dual laminate piping with minimal down time.

You told us the new product had to match lined steel dimensions, and require no thermoplastic welding.

You told us you wanted the convenience of cutting your dual laminate pipe to custom lengths.

And you told us that using your maintentance crew was preferable to calling for service.

Introducing MAXARFlex the newest innovative product from RPS Composites. One that puts control back into your hands. Literally.

Saves Time and Money

Consider the many benefits this product will give you:

Product FeaturesBenefits to YouMAXARFLEXLined Steel
Seamless bonded linerFull vacuum rating. Eliminates liner failures, particularly in thermal cycling applications. No need for weep holes and the subsequent potential for highly corrosive leaks. 
Lined steel fitting dimensionsBolt in replacement of corroded or failing lined steel fittings
Corrosion resistant FRP structureNo external painting or coating required 
Light weight – less than one-third the weight of carbon steel pipeSafer to handle, faster to install 
Inventory of standard pipe and fittingsReduced down time
Lap joint flanges availableFlexibility in bolt hole alignment, faster installation
FEP, PVDF, PFA liner materialsOptimizing cost and performance for your specific service
Inherently corrosion resistant throughoutLower life cycle cost 
No metallic or thermoplastic welding requiredNo hot work permit; no composites technician expertise; easy field fabrication for lower installed cost 

How MAXARFlex Works

  1. Your maintenance team identifies a section of fluoropolymer-lined steel or fluoropolymer-lined FRP that needs replacing. This system is compatible with 1½”, 2”, 3”, and 4” diameter pipe.
  2. Workers retrieve replacement MAXAR™ pipe from inventory and prepare the end(s) with the MAXARFlex tooling kit.
  3. With the skyving tool they remove the outer FRP, and install a new RPS DuoForm flange.
  4. They trim and flare the liner.
  5. Repeat for the other end, if necessary, and place into service.
