Stainless Steel Forged NPT Threaded Male Adapter Tube Fittings
1.Twin ferrule fittings provide metal-to-metal seal connections, non-elastomeric seals for leak-free connections.
2.Twin ferrule fittings is designed to have a maximum allowable working pressure that is higher than  that of any tubing.
3.Stainless steel tube harderness: the hardness of the tube shall be not greater than 85 HRB.
4.Available in sizes from 1/16 to 2in and 2 mm to 50 mm.
5.Fittings materials include 316 stainless steel, steel, brass, aluminum, nickel-copper, Hastelloy C, Â 6Mo, Incoloy 625 and 825.
6.Special treated Back ferrule is to provide secure.
7.Silver coated threads to reduce galling.
8.Leak-proof joints capable of satisfying high pressure vacuum and vibration applications.
9.Industry standard design for all instrumentation grade tubing.
1.Hydraulic proof pressure test (1.5 times the maximum permissible working pressure): no leakage.
2.Dismantling and reassembly test (dismantle ten times): no leakage.
3.Vacuum test (1 × 10−4 mbar or greater): the leak rate less than 1 × 10−8.
4.Maximum static gas pressure test (with nitrogen gas to 150% of pressure rating): no visible bubbles.
5.Hydraulic impulse and vibration test (the pressure impulses at between 0.5 Hz and 1.7 Hz and the vibration  at between 23 Hz and 47 Hz): no leakage.
6.Thermal cycle test (ambient to +80 °C and then to -25 °C with a hydrostatic pressure): no evidence of leakage.
7.Pneumatic pressure vibration test (The frequency of vibration shall be set at 45 Hz and complete 20 × 106  cycles): without failure
8.Fire test (in accordance with BS ISO 19921): no leakage.
9.Corrosion resistance test (the duration of exposure at least 168 h): no visible evidence of corrosion.
10.Deep water submersion test (equivalent to 3048 m of sea water): no helium detected.
11.Minimum hydrostatic pressure test (four times the maximum permissible ambient pressure rating): no  leakage.
