EXPANSION AND CONTRACTION
Each KLAMFLEX Coupling will accommodate maximum pipe movement of 10mm and each flange adaptor 5mm. This is achieved by deformation of the sealing ring, not by a sliding action of the ring on the pipe and will cater for expansion and contraction resulting from temperature variations experienced under normal atmospheric conditions.
The resistance to pipe end separation offered by couplings is dependant upon the number of variable installation factors such as pipe surface, pipe tolerance, coupling component tolerances, etc. and is thus different for every case. For complete safety it is advisable to assume that the worst conditions prevail for each installation.
CARE MUST BE TAKEN TO MAINTAIN SETTING GAPS WITHIN THE LIMITS
