The need for a line thaw happens when process flow is interrupted inside the system and the product temperature drops to a level that inhibits the flow of the product.
Cold climates, lack of insulation on the piping systems and a lack of steam tracing can also be contributors.
There are safety concerns that must be addressed first before any heat is applied to a system that has blocked product in the system.
Each product has a lower explosive limit (LEL) and an upper explosive limit (UEL) knowing these for each product type in the system you will be working on will help set proper temperatures and alleviate any potential for safety issues once heat is applied.
Some systems can be long and have bends, valves or lower lying areas that the product will settle in first before other areas. These areas are typical of where product may gather and congeal first
Applied heat in the known blocked or congealed areas in the form of electrical resistance heating elements or induction coils can help liquify the product in the system quickly.
Having a form of pressure applied into the system like high pressure steam or air can help push the product once it begins to liquify.
Axioms ability to ask the right questions and our understanding of product LEL & UEL give our customers confidence that we will work safely and diligently to apply the correct heating methods and applications with our line thaw services to get them back to production as quickly as possible. Our professional services will also extend to preventive maintenance, assisting customers with measures and methods that helps keep them productive.
