Metal hose is the sole means of transferring cryogenic liquids with minimal evaporation and without significant changes in temperature or pressure. Penflex has thus consistently refined its manufacturing and leak testing processes to best serve this market.
Helium Mass Spectrometer Testing for Cryogenic Hose
Ronit Patil, Penflex Inside Sales/Application Engineer, discusses the step-by-step process for testing cryogenic hose assemblies using a mass spectrometer.
Welder Training Program
Dave Gregor, Penflex Certified Weld Educator, explains what welders can expect during our one-week ASME Section IX certified program designed to improve their welding technique. Upon completion of the program, welders receive weld performance coupons, a Penflex Certification of Completion and ASME Section IX Certificates.
A few words from our satisfied customers…
“Thank you for the training and instruction we received. The qualifications and information we received are invaluable. After welding metal hose for twelve years we assumed everything was right. The best way I could explain to you is that “we didn’t know what we didn’t know.”
— Owner, Leading Supplier and Manufacturer in Fluid Transfer and Sealing Industry
“Worth every penny.”
— President, Fabricating Distributor Organization

Non-Standard Alloys and High Pressures
Here we look at how mechanical properties of austenitic steels are influenced by cryogenic temperatures and what types of stainless steel alloys are best suited for low temperature applications.
In additional to 304, 304L, 316, 316L and 321, we also offer non-standard alloys Monel 400, Hastelloy C276, Inconel 600 and Inconel 625.
