Expansion Joint design can include one or more metal bellows
WHAT IS
AN EXPANSION JOINT?
There can be various terms used to refer Expansion Joints, such as, expansion bellows, flexible joints, pipeline bellows, compensators, piping expansion joints and many more terms. When answering the question “What is an expansion joint?” it can be specify as a flexible component designed to absorb the dimensional changes of steel pipe systems and ducts. The changes could be heat-induced expansion and contraction, vibrations caused by rotating machinery or pressure deformations and misalignment during installation or building settlements.
Metal Bellows are usually a critical component of a complete pipe system. Expansion Joint design can be consist of one or more metal bellows that is most commonly made out of stainless steel or other materials such as rubber, fabric, plastic etc. Further, Expansion Joints and Bellows are widely used in industries where thermal expansion in pipe systems occurs and in order to prolong the service life of pipe systems and reduce the risk of their downtime for additional maintenance and repair.
INDUSTRIES & applications
WHERE TO USE
EXPANSION JOINTS?
Expansion Joints find importance in many industries and are used extensively in among others:
- Energy sector (power plants, nuclear power plants, district heating pipe systems etc.)
- Steel plants
- Petrochemical industry (oil refineries, pumping stations, oil rigs etc.)
- Chemical industries (asphalt manufacturers etc.)
- Process industry (sugar factories etc.)
- Exhaust systems and engines
- Pulp and paper industries
- LNG/LPG tankers, -carriers etc.
ENGINEERED FLEXIBLE SOLUTIONS
ADVANTAGES OF
USING EXPANSION BELLOWS?
Expansion Joints can be challenging topic to many piping designers and engineers as it can be sometimes challenging to recognize the applicability of expansion Joints over the alternatives (when to use an expansion joint) and what are the advantages of using pipeline expansion joints. We have seen this less awareness regarding the usability of expansion joints vs. alternative flexible solutions has lead for many miss conceptions towards Expansion Joints. Some believe that Expansion Joints should be avoided in a piping system and it could seems initially attractive, but with our experiences and by being the industry for decades, we are not hesitate to declare that Engineered Expansion Joints and Bellows offer wide range of options and advantages compare to the other alternatives.
The advantages include:
- Simple in design and function
- Space reduction
- Weight reduction
- Cost reduction
- Reduce piping systems engineering requirements and design complexity
- Improved flexibility for piping layout
- Reliable and proven in the field
- Further, expansion joints are more effective than alternatives such as pipe bends and pipe loops due to their greater ability to conserve space, their economic efficiency and better performance in absorbing larger movements
choosing the right bellows manufacturers makes the difference, especially when it comes to reliability and quality assurance. It is important to work with a competent and experienced manufacturer that you can trust with previous excellent track records, especially to make sure that you get the required advantages of an Expansion Joint(s) that has been engineered to cater the specific purpose – irrespective of how simple or complicated the operating data. In most of the industries that find usability of Expansion Joints, operational safety and reliable performance plays a crucial role, whether you will replace an existing expansion joint, install an improved expansion bellow solution or if you plan to build a new plant/pipeline and introduce new Expansion Joints. Finally, the safe and reliable operation of a pipe system is highly depend on the performance of all the components.
Therefore, we proudly present Belman Flexibles India as your trusted partner for Expansion Joint requirements with proven track records in many industries as well as the fully coverage of “Global Belman” brand promise that already implemented more than 900,000 Expansion Joint solutions around the world.
INSTALLATION of
EXPANSION JOINTS
Correct installation of Expansion Joint is crucial to avoid unsafe and unreliable operation. Most importnatly, to achieve the maximum service life, presure resistance and other desired project related outcomes, it is very important to carefully handle the installation of Expansion Joints. When Expansion Joints installed incorrectly in the worst case it will lead to a damaged expansion joint and/or pipe system, resulting in an unexpected shutdown. Therefore, we have developed a proper guide for Expansion Joint installations ( The installation guide ) where Belman describes how to ensure a correct installation.
Following is a list of key considerations to keep in mind and make sure,
- That the Expansion joint is designed according to the correct operational data.
- That the expansion joints are placed with the inner sleeve in the correct direction in relation to the flow
- That expansion joints with tie rods, gimbals or hinges are placed in the correct angle in the pipe system, so they are not prevented by the pipeline from absorbing movements.
It is also important to consider the following during the installation and handling of expansion joints:
- Correct storage and transport
- Correct removal of transport fittings / pretensioning fittings
- Correct expansion installation in all stages
- Understanding of flow direction
- Correct placement of anchors/guides
- Correct preparation and completion of pressure test
- Correct maintenance
You can find more information about these important points in the Belman Expansion joint installation guide, which is available in multiple languages.
