Pipe metal expansion bellows joints are necessary to ensure that the thermal expansion of the pipe is correctly directed to the metal expansion joint and to prevent buckling of the line. Additional guides are required located next to the expansion joint due to the inherent flexibility of the bellows and the compressive load on the pipe produced by the pressure thrust of the joint expansion.
A bellows consists of several capsules. The capsule consists of two circular wound membranes (usually stainless steel) which are tightly sealed around the circumference. Bellows members consist of tubular membranes wound around the circumference. The membrane is attached at one end to the source and at the other end to a display or instrument. The bellows member can provide a long range of travel (stroke) in the direction of the arrow when pressure is applied.
Metal bellows expansion joints are very versatile because they manufactured with different tensile strength, chemical and physical properties. At the time of manufacturing metal bellows in a bellows machine, there are a variety of materials to choose from. Each material has its own advantages, use, depending on the metal bellows application.Whether it is for the purpose of flight control, safety, firing mechanism, pipes, the bellows plays a crucial role in the efficiency of the various industries. They are presented as the most flexible tool for many types of industries.
Expansion joints are often used for industrial application of piping networks. An expansion joint is also known as movement joint which is categorised into several types, one of its types is pressure balanced expansion joints.Pressure balance expansion joint is a type of pressure balancing bellow which is basically used as a combination of flow bellows as well as the balancing bellows. It is used when the process requires a large change in temperature, pressure and change in size. It is designed with several bellows where the pressure thrust force act across the tie rods attached to the flanges, such as turbines.

This question is asked time and again by everyone, but there are many bellow designing specifications that define the major differences between the two product.An in-depth look at how to specify different bellows and ultimately choose the right one.In this article, we explain you on the difference between single or multiple flexible metallic bellows and non metallic bellows. Well, an expansion joint is more likely used in piping systems and prevent from being crushed. But among the two which expansion joint is best for any industrial specific application? Lets us first understand the two types of expansion joints, what are these:
It's difficult to choose among various metal expansion bellows, and in-depth knowledge is required to choose the right one.Metal bellows are considered as the basic part (generic term) - it is a key component made by forming metal cylindrical into annular corrugation at various atmospheric pressure. These expansion joints are specially designed as per the specification defined by the engineers specifying the dimension, type of metal alloy and the technology used.Bellows is designed and used as a versatile component.They are used in various industry for different application and this application can be broad categories—sealing, temperature, evacuation, and pressure which can be referred to bellow designing process.
Due to change in temperature or high pressure, there is always a chance of pipe expansion/contraction and unwanted contraction in pipe size is dangerous in the industrial utilization, which can lead to circumstances. So for avoiding such kinds of accidents, metal bellows are used in a large number of industrial applications. These metal vessels get compressed if external pressure is applied to it and retrieve its shape when pressure is released. Previously, metal bellows were used in limited industries but now they are used in various industries and market segment like aerospace industry, diesel industry, automation industry including medical application like implantable drug pumps.
Leveraging on our experience and expertise from last 40 years Pliant Bellows is a leading metal expansion joints and stainless steel bellows supplier and manufacturer in India.Metal bellows forming is in practice for thousands of years but after the industrial revolution more sophisticated and hi-technology methods were discovered that made machine industry more powerful and increased their productivity, part repeatability for the better quality products which resulted in improved life. Pliant Bellows provide a broad variety of metal bellow expansion joints to industrial pipeline framework.
A coupling is mechanical device used for multiple applications such as Dismantling pipe lines, Loading and unloading of Liquids. It has been designed to connect two shafts together at their ends for transmitting the power. Generally couplings do not allow disconnections of shafts during operation. The ultimate goal of couplings is to connect two portions of rotating devices. While allowing some degree of misalignment, action or both and for revolution frequency in momentum and positioning factors.
