Expansion joints, often known as metal bellows, play an important role in pipe and ducting systems. They are intended to absorb thermal expansion and contraction, as well as other forms of movement, in order to prevent damage and failure.
This article will go over the significance of metal expansion joints, as well as its uses and numerous varieties.
Expansion Joints
Metal Expansion Joints, also known as metal bellows or compensators, are mechanical devices used to absorb thermal expansion or contraction in piping systems, ductwork, and other industrial applications.They are intended to accommodate system movement induced by temperature fluctuations, vibration, or other causes that might cause stress, fatigue, or system failure.
Metallic expansion joints are constructed of one or more convoluted metal bellows, generally stainless steel, that are attached to flanges or other fittings. The bellows are designed to bend and compress as the system expands and collapses, maintaining the system's integrity and preventing damage.
DMA Bellows is one of the leading metallic expansion joint manufacturers and hose fitting manufacturers in India. Our cutting-edge manufacturing plant enables us to produce metal expansion joints and bellows with exceptional quality and precision.
The Types of Expansion Joints:-
Stainless steel expansion joints are widely utilised in a variety of sectors, including oil and gas, chemical processing, power generation, and HVAC systems. They are essential components that contribute to the safe and dependable operation of piping and ductwork systems.
Metal expansion joints are commonly used in the following applications:
Expansion along an axis Joints that absorb movement in the axial direction or parallel to the length of the bellows.
Lateral expansion joints are designed to absorb movement in the lateral or perpendicular direction to the length of the bellows.
Universal expansion joints are intended to absorb movement both axially and laterally.
Gimbal expansion joints are used in systems to allow for angular movement. Angular movement in every plane is possible because to the employment of two pairs of hinges connected to a common floating gimbal ring. The hinged gimbal ring and pins are designed to reduce the pressure thrust induced by internal pressure and shear forces. Round or square gimbal rings are available.
Single Unrestrained Joints: These expansion joints are made up of a single bellows element as well as end connectors.
As a Metal Expansion Joint manufacturer, DMA Bellows also sells this model that absorbs all movements in any length of piping regardless of accessories such as liners and covers, but it is primarily used to absorb axial movements.
Single Tied Expansion Joint: Tied expansion joints have a set overall length. The tie rods are fastened in such a way that there is no axial movement and the ends of the EJ are always parallel. This arrangement features two degrees of freedom, both of which are lateral in two axes.
Elbow Pressure Balanced Expansion Joints: An elbow pressure balanced expansion joint absorbs externally forced axial movement without increasing pressure to the system. This is performed by connecting two bellows that work in opposing directions and are connected at line pressure.
