Product Features
KLAMFLEX Ranger Couplings (mark holder of SANS 1808-2), in the form of Wide Range Couplings are designed to join pipes of various outside diameters with the same or different nominal bore.
Because of the wide range tolerance on OD (Up to 23mm) a single KLAMFLEX Ranger Coupling can connect steel, ductile iron, UPVC, cast iron, asbestos cement, and other rigid pipe materials.
This eliminates on site guesswork and stock range holdings are optimized. The ability of KLAMFLEX Ranger Couplings to join dissimilar pipe materials is a bonus feature in both repair or permanent situations.
Corrosion protection for KLAMFLEX Ranger Couplings is available in Fusion Bonded Epoxy, Red Oxide Primer, and Galvanized finish as standard. Optional coatings to customer specifications are available upon request.
KLAMFLEX Ranger Couplings have applications in the reticulation of portable water, waste water and sewage as well as in the marine, mining, oil, gas and general engineering sectors. Molded, circumferentially ribbed or specially profiled gaskets, generally in EPDM or NBR materials, provided for smooth installation by minimizing contact friction.
KLAMFLEX Ranger Coupling Gaskets are designed to provide a leak tight seal across the O.D range per nominal size and still allow for thermal expansion and contraction of the pipe up to 5mm per gasket, facilitated through gasket deformation.
To facilitate installation and avoid possible creep under rising load, it is strongly recommended that the KLAMFLEX Ranger Coupling Rubber Sealing Gaskets are well lubricated with a suitable non-toxic soap solution before introduction of the pipe.
This practice should obviate the need for re-tightening the fasteners after pressure testing, and further facilitate the seating of the joint components.
KLAMFLEX Ranger Couplings can be manufactured with double sleeves to prevent end pull-out on PE, HDPE, and GRP pipes.
KLAMFLEX Ranger Couplings are NOT DESIGNED TO RESIST END LOAD due to pressure forces and therefore such forces must normally be resisted by other means.
