Volume Expansion Joint
CHARACTERISTICS:
Excellent reliability, no ageing, absence of permeability, resistant to corrosion, high working temperature.
Calculation of life cycles according to EJMA (Expansion Joint Manufacturer Association) Standards.
MATERIALS:
Materials according to Customer’s specifications
CONSTRUCTION:
– Single-ply metal corrugated bellows
– Ends: according to Customer’s specifications
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:
– Helium leak test (standard).
– Specific dimensional controls, non-destructive tests, material certificates of main pressure bearing parts (on request).
FITTINGS:
According to Customer’s specifications
USE:
Volume compensation of dielectric oil in transformers and insulators
APPLICATIONS:
Transformers
TEMPERATURE:
Stainless steel -200° ÷ 550°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.
