Did you know that isolation via nitrogen freezing has been in use for over 100 years? It’s a great alternative to line stopping in commercial and industrial areas with limited access and is an ideal solution for small diameter size-on-size valve installation.
Line freezing can also be useful for valve maintenance, repair, or replacement on both vertical and horizonal planes. Additionally, nitrogen ice plugging can also provide a secondary isolation when only a single valve isolation exists.
We can perform this service on virtually any size and type of pipe, including but not limited to stainless steel, cast and ductile iron, aluminum, HDPE and other lined and coated pipes.
Recently we completed these nitrogen line freezes in Burnaby and Vancouver high-rises on carbon steel and copper.
