Metragator

metragator-bg

Externally pressurized metal expansion joint

The Metragator solves the problem of long axial travel for expansion joints. It comes standard for movements of 4″, 6″ and 8″. They are available in 150 and 300 psi models, and can be configured as doubles if required.

Maximum Working Pressure: 150 or 300 psi

Maximum Working Temperature: 700°F or 850°F

Test Pressure: 225/450 psi

Bellows: 2-Ply T304 S/S
