General technical guidance

The following explains this component family; it is not a specification or approval of the supplied WH variant.

Rectangular construction choices

A rectangular joint can use a metal bellows or a fabric-based flexible element. For metal designs, corner geometry, convolution arrangement, frame and any flow liner form part of the engineered assembly. Confirm which construction is required before specifying a replacement.

Connection and movement selection

Record clear duct opening, frame dimensions, bolt-hole pattern, installed length and required axial/lateral movement. A rectangular outline alone does not establish interchangeability or the movement envelope.

Confirm before ordering

Confirm the manufacturer and model or the applicable assembly drawing.
Confirm nominal size, overall length and end-connection dimensions.
Confirm the pressure–temperature operating envelope for the fluid and service conditions.
Confirm axial, lateral and angular movement, cycle conditions and any simultaneous-movement limits.
Confirm end type, size, material and the applicable flange or thread standard.
Configuration: Construction and layer/material schedule; duct width × height (mm); corner radius (mm); frame/flange/bolt pattern; gas velocity and dust/condensate conditions.
Use the confirmed manufacturer/model data for operating limits, compatibility and any required certification.
