PMC conducts bag off flowstopping activities on both metallic and PE pipes.
We conduct the following bag offs:
Low pressure bagging off 3” - 12” using Wask 312 equipment - this involves drilling and entry into the main and inserting a deflated bag. This is then inflated to achieve a flowstop.
Low pressure bagging off 14” – 48” using ALH equipment.
Medium pressure bagging off using IRIS stop equipment - this is for planned flow stop operations on cast iron, ductile iron and steel mains on pipe diameters ranging from 14 inch up to and including 48 inch.
Where required, bypasses can be fitted.
