Thread Welded Outlet   

We have experience with over 3000 types of high pressure fittings,and if we know the dimensions, we can supply them even without drawings. 

Our rolling machinery's range of application is narrow compared with threaded processing on an NC lathe using a threaded tip, but the cost and speed benefits are considerable.

We can supply a wide range of high-pressure fittings in sizes from 1/4 to 2 inches.

Performance: 

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

Maximum static gas pressure test (with nitrogen gas to 150% of pressure rating):no visible bubbles.

Hydraulic impulse and vibration test (the pressure impulses at between 0.5Hz and 1.7Hz and vibration at between 23Hz and 47Hz): no leakage.

Thermal cycle test (ambient to +80°C and then to -25°C with a hydrostatic pressure):no evidence of leakage.

Pneumatic pressure vibration test (the frequency of vibration shall be set at 45Hz and complete 20*106 cycles): without failure.

Fire test (in accordance with BS ISO 19921): no leakage.

Corrosion resistance test (the duration of exposure at least 168h): no visible evidence of corrosion)

Dee water submersion test (equivalent to 3048m sea water): no helium
