Finding use in engine exhaust, these Manifold Bellows support isolation of engine vibration and high temperatures. For precise usage with flange end connection, we require customers to provide us with exact make and model of engine. Further, the use of latest technology support also makes these bellows provide for optimum functionality support in given applications. Further, we can also custom develop these as per the specific design and construction requirements of the customers.

Rectangular Bellows are custom made bellows as per client requirements. They are easy to operate, durable, user friendly in nature, optimum performance, highly efficient and have a long life.

They are used In:

• Power transformer
• Sugar plant
• Generator manufacturing industries

• Delivery Time: 2-3 Weeks

Available in universal and axial type configurations, these Hinged Bellows options help in absorbing of angular rotation in single plane through use of pair of pins through hinge plates. Used in sets of 2/3, these can handle full pressure shear and thrust loads while not requiring additional supports and anchors. Some of its other benefits include eliminating pressure thrust forces, preventing torsion, providing positive control over movements and efficiently absorbing thermal deflections among others.

Solving excessive loading issues on piping and equipment, these Pressure Balanced Bellow options provide for higher area of balancing which is twice in comparison to line bellows. Further, the pressure thrust forces also get canceled acting across tie rods attached to tie flanges. The offered expansion joints also accept full axial movement without loading anchors with pressure thrust. Some of its features include accepting axial and lateral movements of piping systems, absorbing pressure thrust and finding suitability for connecting on flanges of pumps or turbines where minimum movement force is needed.

Providing support for axial movement, lateral deflection and angular rotation, these Universal Bellows comprise two bellows that are joined using spool piece for absorbing any combination of above three basic movements. Its primary use includes accepting large lateral deflections as well as adjusting spool piece for increasing/decreasing of its lateral deflection capability. Further, we can offer these bellows with/without tie rods options that connects unit end and also help in restraining of pressure thrust load. Some of its advantages include supporting joining or bending of expansion joint depending on application for angular or lateral deflection, capability to accept thermal expansion of entire unit's length and others.

The Gimbal Bellow is basically similar to hinge type, except that instead of being limited to deflection in only one plane gimbal Expansion Joints are used to absorb angular rotation in any plane, using two pairs of hinges attached to a common floating gimbal ring. Gimbal systems generally consist of two gimbal expansion joints or two gimbals and one hinged expansion joint/bellow. The advantages of this type of construction are it provides a close control over the movement imposed upon the bellows and also supports the dead weight of the pipe. In addition, the wind and shear loads are also taken care of by the gimbal structure. Gimbal bellows joints are designed to absorb the full pressure thrust load of the expansion joint and thus guard the adjacent equipment against damage due to thrust loading.

 

Since gimbal bellows joints are not restricted to a single plane they offer greater flexibility of usage. The use of gimbal bellows joints results in the best system which eliminates the effects of thermal growth and lowers both reaction forces and installation costs. Expensive main anchors are eliminated and only minimal guiding is required.

 

Features:

• Protects the microscope from external damages
• Highly durable
• Economical
