Truthfully, a shell and tube heat exchanger is a technological marvel. You can pass both hot and cold fluids without letting the two touch or mix. However, you can exchange their temperatures in a sealed tube. This delicate process requires only the best shell and tube heat exchanger. If a facility's unit is in trouble, it's time to replace it. Here are five easy ways to determine the right time.
Poor Shell and Tube Inlet and Outlet Sealing
Any shell and tube heat exchanger works effectively if its seals are well-maintained. Unfortunately, the seals will wear and tear due to daily operations. Many manufacturers can provide replacement seals, but if the inlets and outlets themselves have become too worn, it's time to replace the entire unit.
Slowing Liquid Flow Rate
High-quality exchangers work with an ideal temperature, substance-dependent flow rate, and air pressure. If the liquid flow rate is slowing or has abnormal speed changes, you'll want to have maintenance experts evaluate and determine the causes.
Abnormal Output
All exchanger circuits depend on their consistent output. Therefore, any changes can result in problematic consequences that will affect a plant's daily operations. Plus, abnormal outputs will affect the efficiency of chemicals and pharmaceuticals.
Loud, Unusual Noises
Most mechanical equipment emits loud, unusual noises upon reaching their end-of-life. It's a sign of abnormal internal pressure or the possible wear of its internal components for exchangers. Daily passing hot and cold liquids can cause massive damages even on its most resistant parts.
Used for More Than a Decade
Any machine in use for more than ten years is susceptible to damage. If you've been using your exchangers for more than a decade, it might be best to replace them with fresh units soon.
