Technical Information & Product Resources
Explore comprehensive technical documentation covering KLAMFLEX couplings, flange adaptors, dismantling joints, and related pipe connection products.
Working Pressure
Working pressure varies according to coupling size and material used, and is generally up to two-thirds of the maximum test pressure shown in the applicable schedules of dimensions.
Expansion and Contraction
Understand how KLAMFLEX couplings and flange adaptors handle pipe expansion and contraction caused by temperature changes, with guidance on movement limits, sealing mechanics, and installation safety.
Temperature
KLAMFLEX couplings and adaptors operate up to 90ºC with standard EPDM gaskets. Learn about temperature limits, bolt re-tightening, and suitability for fluctuating temperature systems.
Shear Strength
Understand the shear strength capabilities of KLAMFLEX couplings, including load limits for suspended pipelines and support requirements for Ranger Couplings.
Recommended Bolt Torque
View recommended bolt torque specifications for KLAMFLEX couplings, including M12 and M16 bolts up to PN16. GRP pipe torque ratings require supplier consultation.
Pipe End Preparation
Guidance on preparing pipe ends for KLAMFLEX couplings, following SABS 719 and BS 534 standards, with emphasis on sealing surface quality and assembly clearance.
Angular Deflection
KLAMFLEX couplings accommodate angular deflection to correct misalignment, follow curves, and absorb ground movement. View allowable angles by coupling size.
Lateral Displacement
KLAMFLEX couplings require two units and a center pipe section to accommodate lateral displacement. Learn calculation methods for minimum center pipe length by pipe diameter.
Ground Settlement
KLAMFLEX couplings accommodate ground settlement near underground structures using a pair of couplings and a flexible pipe section to relieve stresses and allow angulation.
Setting Gaps
Ensure pipeline safety with KLAMFLEX setting gap guidelines that accommodate temperature changes and pipe movement. Includes recommendations for couplings and flange adaptors by size.
Product Storage
Store KLAMFLEX products below 20°C, away from sunlight and electrical hazards. Keep sealing rings unstressed for best performance.
Cathodic Protection
Maintaining electrical continuity between connected pipes and providing cathodic protection where required to counter the interruption of current caused by the rubber sealing gasket.
Anchoring and Supporting Pipes
KLAMFLEX recommends anchored and guided supports to control axial pipe movement, allowing safe expansion across two couplings.
