Metal Bellows Manufacturers | Metal Expansion Joints

1. Metal Bellows Manufacturer - Metal Bellows Expansion Joints

2. Be it aerospace, automobile, electrical, power generation, or any other, there is a need to transfer fluids safely and conveniently. To cater to this specific need, metallic bellow expansion joints are used. These ​metal expansion joints use metal bellows to ensure that the transfer system has the capacity to withstand the high temperature and pressure as well as withhold the stress caused by these. Kwality Products are one of the leading metal bellow companies, manufacturing various types of metal expansion joints and metal bellows as per the specific requirements of our valuable clients. What are Bellow Expansion Joints? Bellows expansion joints comprise of a bellow, end fittings, control rods, liners, and other components to form an entire unit that can withstand the forces developed by the fluid to ensure an uninterrupted and safe flow. Bellows can be made using a metal or rubber as per the requirement. The metallic bellow is made by rolling a thin sheet into a cylindrical form and then welding the seam. Depending upon the required specifications, plies are added. After this, circumferential convolutions are made onto the body. The shape of these is designed in order to contain the pressure developed inside and deform accordingly. When the pipe is subjected to high pressure, the bellows compress, and alternately, when there is a vacuum, the bellows expand accordingly thereby protecting the whole arrangement. Kwality Products is a metal expansion joints and metal bellows manufacturer that uses state of the art mechanical expander and hydroforming machines to manufacture bellow joints as per the design parameters required by the client industry. Use of Metal Bellows The ​bellow expansion joints have found uses in a plethora of industries ranging from water/wastewater plants to even nuclear applications. Some other applications of the bellows are in - ● ● ● ● ● ● ● ● ● ● ● ● ● Power generation plants Infrastructure HVAC Solar technology Electrical systems Cryogenic/industrial gases applications Metal/steel mills Measurement and control systems Fuel cell power system Pulp and paper industry Oil and gas OEM engines Shipbuilding and repair

3. ● Automotives, etc. Benefits of Metal Expansion Joints The benefits of choosing metallic expansion joints can be specified as below - Vibration isolation: ​Unnecessary vibrations in systems can damage the system as well as the surrounding equipment severely. Metal expansion joints help in isolating these vibrations, as well as dampening noise and pressure surges. Wide temperature ranges: ​These can be used to convey fluids, solids, or abrasive media at high as well as low temperatures safely. Low maintenance: ​By using durable and corrosion-resistant materials, metallic expansion joints require very little maintenance and have a long life cycle.High temperature and pressure resistance. ● ● ● Features of Metal Expansion Joints There are various features of metal expansion joints depending upon the type. The main features are as follows - ● ● ● ● ● ● ● ● ● Absorbs vibrations and oscillations Absorbs mechanical movements Low maintenance cost Compact and lighter, thereby saving space An array of design possibilities Better flexibility for the pipe layout Better performance than traditional pipe bends, loops, etc. Abrasion-resistant Corrosion-resistant Types of Metal Expansion Joints Based on different parameters such as the direction of movements, location the joint is placed, function of the joint, etc, there are a few different types of expansion joints. These are as follows - ● Axial Expansion Joints: These are expansion joints that are used to contain the movement in the axial or longitudinal direction. When used in between two pipe sections, due to the thermal expansion, this joint compresses and expands along the length as required, thereby protecting the pipeline. Lateral Expansion Joints: This type of metallic expansion joints is used to compensate all the movements in the lateral (perpendicular to the central axis) direction. With the help of control rods attached, the lateral expansion joints also control the pressure thrust. Hinged Expansion Joints: A hinged expansion joint is used where there is a need to constrain angular deflections in a single plane controlled by a hinge. These are used in piping systems where there is a change in the direction of the flow. ● ●

4. ● Universal Expansion Joints: Universal expansion joints, also sometimes known as a double bellow expansion joint is a device that is made up of 2 bellows attached together by a pipe section. As a result, this can absorb movements that cannot be absorbed in normal axial expansion joints and can also contain deflections in axial, lateral, and angular directions. Gimbal Expansion Joints: Gimbal expansion joints or the angular expansion joints are used to absorb movements in multiple angular directions. With the help of multiple hinges or gimbal, these can constrain the deflections in all the planes. Inline Pressure Balanced Expansion Joints: Inline pressure balanced expansion joints are designed to absorb axial movement without putting a load on the pipe system. This is done by using two bellows in line together and acting in opposite directions. It is mainly used in systems where any pressure on the piping system can prove to be fatal, and therefore must be avoided. Elbow Pressure Balanced Expansion Joints: This type of pressure balanced expansion joint is used in systems where it is not acceptable to transfer pressure on to the piping system and also there is a change in the direction of the flow. These absorb axial movement without imposing pressure loading on the system. ● ● ●
