ISOPAM Anchored Joints
Anchoring system of ISOPAM range
ISOPAM pre-insulated pipelines are designed to provide heat insulation for networks that are especially exposed to risks of freezing. They consist of ductile iron pipes with heat insulation fitted in the factory. Their mechanical and leaktightness properties are identical to those of standard ductile iron pipes.
Pipelines can sometimes be subjected of the risks of freezing. When required by current conditions (low flow rate, unfavourable weather conditions, above-ground installation), pipelines have to be insulated to minimize heat exchanges with the outside environment. PAM offers a factory pre-insulated pipe system to cater for that need.
The angular deflections of ISOPAM pipelines are different from those of non-insulated pipelines owing to the geometric constraints imposed by insulation of the joints.
