DN 50-> 2400. Special and large diameters available upon request
TEMPERATURA -200°C ÷ 800°C.
PRESSIONE From 6 to 16 Bar

VIBRATIONS ABSORBERS WITH FLOATING FLANGES AND TIE-RODS ON FLARED NECKS

CHARACTERISTICS:
Excellent reliability, no ageing, absence of permeability, resistant to corrosion, high working temperature
Absorption of vibrations

 

MATERIALS:
Bellows in stainless steel 1.4541 EN10028-7 (AISI 321)
Flanges in zinc-plated carbon steel
Tie rods in zinc-plated carbon steel
On request, other grades of stainless steel

 

CONSTRUCTION:
– Single or multi-ply metal corrugated bellows
– Ends: flanges
The corrugations are formed by a PLC controlled automatic process
The special forming process, free from friction and lamination, allows constancy and accuracy of the corrugation profile with minimal material yielding

 

TESTING:
– Pneumatic leak test (standard)
– Hydraulic test, specific dimensional controls, non-destructive tests, material certificates of main pressure bearing parts (on request)

 

FITTINGS:
Flanges conforming to EN1092-1 or ANSI B16.5
Special flanges upon request

USE:
Absorption of vibrations

 

APPLICATIONS:
Superheated water, diathermic oil lines; refrigeration plants

 

TEMPERATURE:
Stainless steel: -200° ÷ 550°C
For expansion joints with flanges in carbon steel: -20° ÷ 350°C
For a temperature range 50° ÷ 550°C performances (movements, working pressure, n° of cycles) must be reduced by applying the relevant coefficients (See document N205 Derating factors”).
For a temperature range higher than 550°C, please contact our Technical Department
