China manufacturers stainless steel Twin ferrule tube fitting 

Products Description

• Features

1. Twin ferrule fittings provide metal-to-metal seal connections, non-elastomeric seals for leak-free connections.

2. Hikelok twin ferrule fittings are 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. Hikelok fittings materials include 316 stainless steel, steel, brass, aluminum, nickel-copper, Hastelloy C, 6Mo, Incoloy 625 and 825.

6. Hikelok 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.

• Performance

1. Hydraulic proof pressure test (1.5 times the maximum permissible working pressure): no leakage.

2. Dismantling and reassembly test (dismantle 10 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 (4 times the maximum permissible ambient pressure rating): no leakage.

• Thread Specifications
  

• NPT Thread Pressure Ratings
  

Ratings are based on ASME Code for Pressure Piping B31.3, Process Piping, at ambient temperature.
