Technical Informations / Clamp Interspaces

Fixed clamp interspaces are provided in the below table for PPRC pipes placed horizontally.  Clamp interspaces in the vertical piping system must be same with the clamp interspaces in the horizontal piping system.

Fixed Points:  Fixed points prevent the movements uncontrollable in the system and in addition separate all system into small expansion sections.  The places of the fixed points are identified by taking into account stretching amount, weight, type of liquid inside of the pipe and other forces, if any.  

Fixed points must be more robust than the pushing force of the free bending part.  Fixed points must be placed in proper distances so as to enable expansion.

Fixed points are used to fasten pipes firmly on a place.  Fixed points make use of the muff and fitting weld places in the terminals or double side fixing systems.
