If this is so safe, why won’t CRYOSTOP™ International freeze plugs over a joint weld or simple dent?

Cryostop International is a safety-driven company. We know that Cryostop™ freeze plugs are a well engineered procedure with large safety factors built into it. We don’t want to use up any safety factor unnecessarily. Welds, dents, gouges, scrapes, corrosion pits and the like often hide dangerously weakened spots in pipe — these are the spots where leaks occur. That’s why CRYOSTOP International’s pre-job inspection of your pipe is so important. We will work with customers that absolutely must Cryostop™ freeze plug over a welded joint or known defect, but it won’t be easy and the customer should consider a mechanical line stop offered by our sister company, MTITAPS.
