Metal Expansion Joints
Being amongst the fastest growing companies, we are affianced in manufacturing and exporting a reliable range of Metal Expansion Joints. With the availability in different specifications, these expansion joints are immensely used in various piping applications in different industries. These joints are manufactured by our experts as per EJMA Standards using high grade quality metals. Prior to dispatch, Metal Expansion Joints are stringently checked by our expert quality analyzers on various quality norms.
- Highly flexible
- Weather resistance
- Noise resistance
Alfa offers Single Ply as well as Multi-ply bellows membranes and Expansion Joints in sizes 20mm to 2000mm Nominal diameter. Bellows sizes 20mm to 300mm are made by hydraulic process while higher diameter are made by roll forming. Bellows are made as per EJMA Standards as well as with customer specification. Alfa has a standard range of single ply bellows for engine exhaust application and general purpose low pressure application.
Metal bellows are generally used in pipeline systems, which connect the pumps and vessels. The design of the folds in metal bellow permits greater axial, lateral, and angular movements. To increase the angular or lateral flexibility, the ties, pivots or other trimmings can be added to a metal bellow. The service life of these devices is determined on the basis of shape, material and degree to which the junction must be able to move, and of course, forces that are more than the designed limits.
We design and supply Single Ply as well as Multi-ply bellows membranes and expansion joints in various sizes ranging from 20 mm to 2000-mm nominal diameter. The bellows in sizes of 20 mm to 300 mm are fabricated using the hydraulic process while higher diameter is made using the roll forming.
Using these bellows, flanged-end and fused-end expansion joints can be easily and smoothly fabricated. Both universal as well as double expansion joints uses two bellows.
Our bellows are designed as per the EJMA Standards, however, we are capable to design these with customization to suit specific customer specifications. We have a standard range of single ply bellows for uses in engine exhaust applications as well as general-purpose and low-pressure applications.
Application of Products
The quality metal expansion joints supplied by us have found crucial applications in pipeline technology and are used to counterbalance length changes, which generally occur in pipelines due to temperature changes. Besides this, the metal expansion joints are capable of absorbing the vibrations developed from pumps, engines, compressors or turbines. Depending on the problem, the axial, lateral as well as angular movements can be compensated. Metal expansion joints provide cost advantage and increase the service life of a pipeline system.
