We serve worldwide, but majorly we serve our products to customers from European, American, Gulf and Asian Countries.

◈ Canvas Expansion Joints
These are the most common cheaply made basic type of ducting air flow bellows expansion joints fitted in the path of air flow between the blower and the adjoining duction. We make these bellows in all kinds of shapes and sizes as per customers requirements.
Installed as flexible joints in Air, Fuel Gas ducts to compensate for Thermal Expansion, Vibration & Noise Dampening & Duct Axis Misalignment's. Our joints can be designed & manufactured to compensate for various possible duct movements as shown below.

◈ High Temperature Flexible Expansion Joints
These are the most common basic type of ducting air flow bellows expansion joints fitted in the path of air flow between the blower and the adjoining duction. We make these bellows in all kinds of shapes and sizes as per customers requirements. Suitable for high temperature environment and air flow upto 1100 deg cel.

◈ Rubber Moulded Expansion Joints
These are oil, water, air or chemical flow rubber moulded single or double hump expansion joints fitted in the piping line of the flow. These come with all kinds of steel or cast flange standards as per clients requirements.
EXPANSION JOINTS EXTRA FEATURES
• Metal Baffles :
As seen in our BF Range of Expansion Joint Designs, these Baffles protect the flexible element from the abrasive & corrosive particles in the air / gas flow stream, casing an smooth air flow & avoiding turbulence & heat accumulation.
• Cavity Insulation Pillow :
We can provide an Insulation Pillow between the flexible element & the Metal Baffle or kines and help prevent the accumulation of particulate mattes & in some application joint cavity. These Pillows are make of Fiberglas or ceramic material.
• Fly Ash Seal :
Wire Mesh type seal can also be provided in conjunction with the above mentioned features, to prevent Fly ash & other solid particle accumulation.


◈ Air Spring Bellows
These are air cushioning bellows used to absorb the shocks in machines and lso elsewhere in the industry.

◈ Food Grade Rubber Expansion Joints
Food grade rubber moulded sleeves and bellows are required in various material flow applications across the food industry. We make certified food grade rubber products to suit the clients needs. We use special grades of EPDM & Silicon Rubber compounds to make these bellows in shapes and sizes as per clients needs.

◈ Oil And Water Rubber Expansion Joints
These are oil, water, air or chemical flow rubber moulded single or double hump expansion joints fitted in the piping line of the flow. These come with all kinds of steel or cast flange standards as per clients requirements.

◈ Piping Expansion Joints And Bellows
These are oil, water, air or chemical flow rubber moulded single or double hump expansion joints fitted in the piping line of the flow of the media. These come with all kinds of steel or cast flange standards as per clients requirements.



◈ Ducting Expansion Joints
We have the required technical expertise along with suitable fabrication facilities to manufacture a wide range of expansion joints. We can supply basic joints made of Thick Canvas, PVC coated Nylon Fabric used for Ducting Applications in Air Flow Systems as well as highers end, high temperature expansion joints. Made of composite, multilayered fabrics such as silicone Fiberglas, Teflon etc., using high temperature sustaining threads for stitching. Our expansion joints are made in flat 'BAND' type, as well as 'U' type of belt. Featured below are some of typical metal flange / frame configurations.
