Different Types Of Designs & Materials Used In Expansion Joints
When we speak about expansion joint, the conversation naturally proceeds to focus on the quality, capabilities and durability. However, people often overlook the optimisation and overall energy efficiency of the piping system. It is important to ensure flexibility in all piping systems. Failing to do so can lead to major catastrophic failure that can be life threatening.
Generally, rubber expansion joints are used in most pipelines as they provide the maximum flexibility. They are the most preferred joining ducts due to resiliency and have the capability of all-directional movement. They are also great at absorbing vibration and accommodating misalignment. Even if the space is limited, rubber expansion joints keep performing to the fullest. There are different types of rubber expansion joints and the type of design for the pipeline is focused when such ducts and joints are purchased. However, be sure that the level of performance may not be achievable with alternatives like pipe loops, grooved couplings and metal expansion joints.
Optimising section wise
The process of expansion joints and their various other applications require systematic and tedious approach. In the first step, the piping must be divided into individual sections that run straight or in L or Z shape and choose a tentative anchor location. Each of the sections can be optimised after that and then can be rejoined with the entire piping system. This results in an efficient system which is completely optimised.
Unrestrained designs are generally the simplest. They are also the most economical and thus, prove to be the greatest solution for expansion joint selection. They primarily relieve thermal stress by absorption of axial movement in rigid piping systems. It is important to use the main anchors with numerous guides at specific spacing to prevent major accidents.
However, with the use of directional main anchor, lateral movements can also be achieved. The unrestrained expansion joint usually has a life cycle, which must be utilised. These expansion joints are capable of reducing noise and vibration, thus compensating misalignment in pipes as well as absorbing shock and anchor loading too. The best thing is, the support structure and adjacent equipment does not have limitations in loading. The joints provides key access to piping and other equipment when a retracting design is not required.
If you want to install the appropriate expansion joint based on the type of pump lines you have, hire a professional pump supplier to get a range of pumps and their respective parts.
