Metal hoses are known by many terms including stainless steel hose, stainless steel lines,
braided steel hose, flex hose, steel hose, flexible metal hose, flexible steel hose, flex metal
hoss, stainless steel lines, steel hoses, steel braided lines, flex line. These all refer to a hose with a
metal liner that may or may not have a metal braided cover. The hose end fittings are welded onto your metal
hoses. Metal hoses are helium leak tested. Flexible metal hoses are excellent high temperature hoses.

THE RIGHT WAY TO TEST FLEXIBLE METAL HOSES
Did You Know....All metal hoses leak! The ONLY way to accurately leak test your metal hoses
is by using helium and a mass spectrometer to determine your leak rate. Most fabricators do not
have mass spectrometers, so instead, they will test your hose by putting it into a bucket of water
and eyeball it for bubbles.

WELDING PROCEDURES
Your flexible metal hoses are welded together according to ASME B31.3 Section IX certified
procedures. Your metal hoses are then helium leak tested with a mass spectrometer if
requested. Further radiograph or x-ray testing, dye penetrant testing and cleaning is available.

You can be confident that, because of superior fabricating welding procedures, and helium
leak testing
capabilities, your flexible metal hoses are the highest quality for your critical
application. Our flexible metal hoses are used by the Navy, NASA, nuclear and power
generation, military contractors, pharmaceutical manufacturers, and chemical manufacturers.
Every hose fabricator will tell you that they make quality hose assemblies. But, Thunder
Technolgies hoses are made wiht state-of-the-art procedures and testing capabilities.

You want to know your metal hose's leak rate
Your flexible metal hose can be tested with a mass spectrometer so we can give you the exact leak
rate of your metal hoses. Unless your specs require a more stringent leak rate, your metal hose will be
tested at a leak rate of 10
-8, or a leak rate of about 1 drop of fluid per year.

Testing metal hose assemblies in a bucket of water DOES NOT give you the leak rate for your
critical metal hose requirements. This inferior metal hose leak testing is not uncommon among metal
hose fabricators.
