Constructive Forms

Configuration Types

There are two basic configuration types: belt and flanged. Both types can be round or rectangular.

Belt Type

This configuration allows flanged or welded connections. Its geometry is more favorable to the fabric belt manufacture. This configuration the advantage of easier belt replacement, without the necessity to disassemble the expansion joint metallic frame.

Flanged Type

This configuration has flanged connection and “U” belt profile. It allows small OAL and a simplified metallic structure, reducing the initial expansion joint cost. Nevertheless, it doesn’t allow an easier belt replacement, which increases the maintenance cost. Maximum operation temperature: 530ºC (1000ºF).
