Industrial Dampers are critical equipment in various places of the ducting system from the boiler to the chimney. They can be used for isolation or flow control. Different designs can be used to give 100% seal tightness for man-safe operations.

Non-Metallic Expansion Joints (NMEJ) offers a number of advantages, especially in plant design and building. They take up movements in several directions simultaneously, have almost no reactive forces, need little space for installation, are easy to adapt to existing physical conditions, and they are easy to transport and install.

The basic element of a Metallic Expansion Joint (MEJ) is the bellows - a flexible, corrugated tubular metal element to absorb movements in a piping system.

Rubber expansion joints provide a proven and flexible solution to accommodate many types of movements and requirements of industrial plant and equipment.

KELD manufactures Lamella Seals in two broad varieties - fabric & spring steel.

Air Slide Fabrics are textile cloth fabrics and are used in air slides for pneumatic conveying of fine dry products like cements and other raw materials. It can also carry Fly Ash, Iron Powder, Gypsum and so on. KELD makes Air Slides with woven selvedge and made to order width. Therefore, bolting with the metal body of the conveying chute is very secure.

KELD can carry out duct insulation both externally and internally. The internal duct insulation is typically done with a floating plate system known as a cladding sheet. This consists of thermal insulation material covered with a cladding sheet to protect the insulation.

KELD fabrication facility is spread over 150,000 sq.ft. of space with a 8,500 sq.ft. built-up shed. With the latest in sheet metal working equipment available in-house, like profile cutting machine, press brake, shearing machining, bending machine, rolling machines, several arc & MIG welding machines, drilling machines, etc.

Slide gate dampers are similar to guillotine dampers, but are mainly used for solid media applications. Ideally suited to be installed in the chute or hopper, these dampers act in effectively opening or closing the flow of material in the duct.

When a hinged expansion joint is used, movement is limited to angulation in one plane. Hinged assemblies are normally used in sets of two or three to absorb large amounts of expansion in high pressure piping system. Only low spring forces are transmitted to the equipment.

The simplest type of expansion joint consists of a single bellow element welded to end fittings, normally flange or pipe ends. The single bellows can absorb small amounts of axial, lateral and angular movement with ease, but adequate anchors and guides must be provided.

Line pressure acts externally on the bellows by means of a pressure chamber. This allows a greater number of convolutions to be used for large axial movements, without fear of bellows instability. Externally pressurized expansion joints have the added benefit of self-draining convolutions if standing media is a concern. Anchors and guides are an essential part of a good installation.
