85 PSIG Single and Multi-ply Stainless Steel Expansion Joint Bellows

ASTM A240 – T 304 S.S., 316 S.S., or 321 S.S. Standard with Welding Aide

(Monel and Inconel available on request)

Notes:

Pressure Range: Vacuum to 50 PSIG for 3/4″ to 1 1/2″ and over, 85 PSIG
Temperature Range: -20 F to 800°F
Rated cycle life is 3000 cycles per EJMA for anyone tabulated axial movement
Maximum Axial extension movement is 50% of the tabulated axial movement
Rated extension movement is equal to rated axial movement provided the bellows is pre-compressed the amount of design extension.
Maximum test pressure: 1.5x design pressure
Materials: Bellows–ASTM A240-T 304 S.S.; 316 S.S; 321 S.S.
Welding Aides–ASTM A240-T 304 S.S.; 316 S.S; 321 S.S.
Flanges or welds ends can be attached to the bellows 1/16″ thick (min.) Welding aide
