Multi Tube Bellow

Introduction Of Multi Tube Bellow

Multi Tube Bellows are one of the products that we market for Insulcon B.V. More information on them can be found on our products page for Multi Tube bellow.
KLAY EnerSol has recently completed a Multi Tube Bellow Installation for a client in Malaysia. The scope of works include modification of the steel support system which was engineered and fabricated using Stainless Steel material. This modification was crucial due to unavailability of a fixing point to hang the MTB at the side of the roof opening.

Support Angle and Multi Tube Bellow

Prior to the installation, the existing insulation materials were removed and the affected area where the steel supports were planning to be installed was cleaned up. Also, the unused anchor from a previous installation was removed.

Existing Insulation Materials That Need to be Removed First

After the removal of the existing insulation materials was done, the steel support needed to be welded at the edge of the furnace opening. The Stitch Weld method was applied in order to prevent the steel support from warping.

The New Support System Constructed from Stainless Steel

Each Multi Tube Bellow is supplied as two parts which are then assembled at the roof opening. For each part, half a section is mounted at the support angle, while the other part is fixed at tube.
