SS316 Compression Instrumentation Tube Fitting
Stainless steel is a highly corrosion resistant material. Our SS316 Compression Instrumentation Tube Fitting
contain a minimum of 10.5% chromium, which makes the tube fittings
ideal for applications that require high
levels of resistance to corrosion. The chromium content in all our SS316 Compression Instrumentation Tube
Fitting can be increased to achieve higher corrosion resistance levels.
Our SS316 Compression Instrumentation
Tube Fitting also have exclusive characteristics like high temperature strength
and ductility. However, the
toughness of the Stainless steel tube fittings we manufacture have
a wide range of variations ranging from
outstanding toughness of the austenitic steels in all types of
temperatures, to the considerably brittle behavior of
the martensitic steels. Whether our SS316 Compression Instrumentation Tube Fitting are corrosion resistant in a
specific environment depends on the combination of chemical
composition in the fittings and the aggressiveness
of the environment. Our Stainless steel tube fittings are widely
used in petrochemical and oil and gas industries..
Double ferrule fittings provide metal-to-metal(all-metal) seal
connections,non-elastomeric seals for leak-free
It is designed to have a maximum allowable working pressure that is
higher than that of any tubing.
industry standard design for all instrumentation grade tubing.
Silver coated threads to reduce galling.

copper, hastelloy C, 6Mo, Incoloy 625 and 825.
Applications: high pressure, vacuum and vibration
Hydraulic proof pressure test (1.5 times the maximum permissible
working pressure):no leakage
Dismantling and reassembly test (dismantle ten times): no leakage.
Minimum hydrostatic pressure test (four times the maximum
permissible ambient pressure rating): no leakage.
Vacuum test (1*10-4 mbar or greater):the leak rate less than 1*10-8 mbar 1/s
