Deflation is usually carried out by detaching the inert gas inflation line
from the supply. The inert gas will simply flow out of the inert gas
connector and the dams will collapse allowing them to be easily removed.
Another perfect pipe weld!
Do not use “makeshift” devices like cardboard dams or foam bungs.
They contain a lot of water, water vapour and air, put your weld at risk
and end up costing you more money.
Use the proper tool for the job!
WARNING
Failure to comply with these instruction procedures may lead to
damage being caused to the dam assembly which may not be
