RB-Flex Bellows type Metallic Expansion Joint manufacturer, are an efficient and functionally reliable method of absorbing differential thermal expansion within a piping or ducting system whilst containing the system’s pressure.

RRD specializes in the production of Stainless Steel expansion joints with joints acting as the flexible element.

RB-FLEX JOINTS TYPE CIRCULAR METALLIC EXPANSION JOINT Manufacturer

Joints starts from coiled Stainless Steel. The same is cut and then welded by a specialized automatic TIG process to form into tubes. The tubes once formed may consist of one or more layer of Stainless Steel which are then formed into convoluted joints by mechanical or Expander process.

The corrugations, commonly referred to as convolutions, add the structural reinforcement necessary for the thin-wall material to contain system pressure. The joints designer selects the thickness and convolution geometry to produce a joints design that approaches, and often exceeds the capacity of the adjoining pipe to contain system pressure at the specified design temperature. Flexibility of the joints is achieved through bending of the convolution sidewalls, as well as flexing within their crest and root radii. In most cases, multiple convolutions are required to provide sufficient flexibility to accommodate the expected expansion and contraction of the piping system.

Virtually all RB-Flex  Joints type Metallic Expansion Joints are manufactured using multi-ply, thin-gauge construction rather than a single thick ply. Multi-ply Construction of RB-Flex Joints type Metallic Expansion Joints  gives greater flexibility along with lower spring rates and increased cyclic life.

RB-FLEX RECTANGULAR EXPANSION JOINT

Rectangular expansion joint are generally suitable for ducting / fan etc.. They can be manufactured with round or bevel corners. It absorbs axial, lateral and angular movements similar to the round metal expansion joints. The bellows element is manufactured from SS / DD quality grade depending up on service conditions.

Duct Expansion Joints are manufactured according to the required size limits. These type of expansion joint are provided with various configurations of corners like

• Bevel corner.
• Double  Mitre.
• Rounded Corner.

SALIENT FETURES OF RB-FLEX EXPANSION JOINT

• Joint is made from multi-ply rather then one single sheet
• Able to absorb movement in multiple direction
• Need small space for installation
• Almost no maintenance
• It reduce load and temperature loss to minimum
• Has a good life
• Is universal and can be replaced in various application unlike other expansion joints
• Designed to EJMA Standards
