Hinge Joints are used to absorb angular movement in one plane only. Commonly used in floating pipework since anchors are not required and minimal guiding required. This type of joint when used in combination of 2 or 3 can absorb lateral, axial and angular movements.
Slotted hinge designs are used when axial movement is to be catered for.
