Which Is The Best Expansion Joint For Your Pumps?

There are various types of expansion joints for a pumping system. However, before making a final decision you need to determine some important component.  
 
An expansion joint is a very important component in a pumping mechanism. Even the simplest mistake can cause catastrophic result. Therefore, choosing the right expansion joint is very important to keep the system safe. When you're choosing an expansion joint be sure to consider the other components and system requirements.
 
Piping Plan
 
Before understanding the expansion joints ensure that the adjoining pipes and equipment complies with the rules and standards of industry. This includes proper placement, design of the anchors, guides and supports for expansion joints.
 
Joint Movement
 
Expansion joints are flexible connectors that are installed to absorb laterals, axial and angular pipe movement, along with vibration. Thus, you need to know about the pipe material as the coefficient of thermal expansion (CTE) greatly depends on the pipe materials.
 
Pumped Media
 
To understanding the compatibility of elastomer selection it's important to know about the process media. The selection of material must not be compromised at any cost during the specifying process. If you choose a marginal tube material it can be very risky as it relates to high replacement costs and/or downtime.
 
Temperature and Pressure 
 
Appropriate temperature and pressure data is the principal factor for expansion joints. If the temperature exceeds 200 degrees Fahrenheit be sure to install proper pressure de-rating system to increase the handling ability of the expansion joint especially when it comes to working pressure at elevated temperature. To prevent deterioration of the reinforced fabric, installation of pressure de-rating is very important.
 
At the discharge point of any pump when connectors are installed, you should consider investigating the point for pulsating or shock. As a rule of thumb the flexible connector or the expansion joint must be rated to withstand immense working pressure to compensate shock pressure.
 
Proper Designed Expansion Joint
 
Expansion joints can be either metallic or non-metallic. All you need to check is whether or not they are properly fitted. Their design also plays an important role from the perspective of safety. Generally a properly designed expansion joint lasts for about 30 years. A good quality expansion joint must show little wear and tear at increased durometer hardness even after a prolonged period.
 
When it comes to reliability of the pumping system you must always focus on the appropriate expansion joint that comes with sound adjacent piping design. Consult your needs with the pump supplier to get the best expansion joint which is suitable for your project.
