The bellow is formed with convolutions and there are many other geometric features provided. Because of its convolution shape, it is also known as corrugated joint. This present study is intended towards rigorous study of various design aspects of expansion joints, and their effect on the performance through several experiments.

For long distance piping applications expansion loops are provided to compensate the variations in length. In certain precise applications different types of expansion joints are used in the piping to avoid high stresses caused due to temperature variations and pressure fluctuations. Design of expansion joints is very critical, as the temperature variations and fluid pressure are most variable parameters depending on individual application. Metallic bellow is the most critical and important part of expansion joint assembly

Piping engineering is very important aspect of tied lateral expansion bellow manufacturers in Vadodara, and other allied industries. All mega plants consist of hundreds of meters of various pipes. Pipes are used for the purpose of long distance transfer of fluids. At some places the pipes are having limited length but complex layout. For many individual applications, fluid pressure and temperature are main variables. A pipeline designer has to make a judicious layout planning providing for expansion for a pipe line even in a confined space to avoid the problems arising out of a stiff piping system

In order to make a system flexible, different types of expansion devices or joints are used. The expansion joints are necessary to consider as part of piping systems and they are introduced at appropriate locations in the following circumstances. The function of expansion joints in various applications is to provide flexibility in the piping. The performance of expansion joint is mainly depends on the design of bellows. The whole assembly of expansion joint consists of other elements like liner, flanges, cover, collar, control rods, limit rod etc.

There are many variations in selection of pipe diameters, length of pipes, fluid which is flowing inside the pipe tied lateral expansion bellow manufacturers in gujarat, properties of fluid, pressure fluctuations, temperature variations, etc. depending upon application. The design of expansion joints should include all these working conditions. Hence the design of expansion joint is very much customized and every individual application is a challenging task to designers. The precise design of tied lateral expansion bellow manufacturers in baroda parameters of expansion joints and study of different geometric parameters of bellows.

An expansion joint can be defined as a device containing one or more bellows used to absorb dimensional changes in the pipe line, duct or vessel caused by thermal expansion and contraction. The main function of expansion joint is to provide flexibility in the piping in order to compensate for variations in length. The expansion joint posses several advantages over conventional compensating devices such as capable of absorbing any movement tied lateral expansion bellow manufacturers in baroda.

The various dimension changes which an expansion joint is required to absorb are axial motion, lateral deflection, angular rotation and torsion movement. Principally bellows are made to absorb axial movements only, but several combinations of bellows can be used as an expansion joint, which are capable of absorbing several movements, Axial movement: It is the movement occurs parallel to the centerline of the tied lateral expansion bellow manufacturers in Vadodara.

Most bellows fail by circumferential in cracking resulting from cyclic bending stresses, or fatigue. Since the simplest design may be a compromise, or balance, between pressure strength and adaptability considerations, it are often concluded that their designs have had lower margins of safety regarding fatigue than they had regarding pressure strength. The years of experience of the engineers who developed these bellows assures that the designs contained during this catalog and people offered to satisfy customer specifications, will have the tied lateral expansion bellow manufacturers in india.

The purpose of metallic expansion bellows is to scale back the reactions/forces & moment at the connected equipment terminals thanks to thermal expansion-contraction and/or vibration of connected equipment and piping.
