The
ARGWELD®
purge material makes dams which produce an
impenetrable purge barrier but which can easily be washed away when
hydrostatically testing the pipe or just by normal wash out.
It dissolves away completely without
leaving any fibres to clog up filters or other sensitive parts in a system
and it is strong in all directions so that it can maintain a good gas
barrier throughout the purging process.
Trace element certification can be
provided to show that ARGWELD® purge film does
not contain any harmful elements and that the quantity of halides is well
below the permissible levels.
The film and adhesive are completely
biodegradable and all packaging materials are recyclable.
