Hydrostatic Testing Risk Containment
Hydrostatic Testing Risk Containment
(OP)
When performing hydrostatic testing on large tube & header assemblies, expandable plugs are often used in place of welded plugs. This presents a major problem if the air is not properly bled. This may be more of a ballistics question, but what type of backup safety precautions are typically taken when hydrotesting large boiler / tube & header assemblies?
The size of plugs range from 1" dia (3/4 lbs) to 16" (350 lbs), and the max testing pressure is 6500 psi.

See bottom of the page---Safety gags
Expando-seal makes a good one also.

Thank you for the link. Are there any other backup systems used to protect against a tether/gag failure? Perhaps woven netting or something of the sort?

Binoculars and good running shoes are always a last option.
