Corrosion

A few years back, a very good customer asked Thermaxx and our partners at MIDCO insulation to perform an insulation audit in multiple manholes on a line running through a busy urban area. The customer expressed some apprehension and frustration because previous attempts at insulating these lines were unsuccessful, as the insulation quickly degraded. Read more.

Common in factories and plants, stainless steel pipes and tubes are something we frequently see in our removable insulation installation calls. In these industrial settings, stainless steel pipes are frequently exposed to extreme temperatures and conditions; thus, insulating them is important to energy savings. Perhaps equally important is inspecting stainless steel pipes…More

Ammonia is a compound of nitrogen and hydrogen, or NH₃.  Because of Ammonia’s vaporization properties, it is frequently used as a refrigerant. NH3 boils at −33.34 °C (−28.012 °F) at a pressure of one atmosphere, Ammonia was commonly used before Freons (chlorofluorocarbons) became popular. Read more.

Corrosion under insulation (CUI) is the corrosion of piping and vessels that occurs beneath insulation as a result of water penetration. The water can come from rain water, leakage, deluge system water, wash water, or sweating from temperature cycling or low temperature operation such as refrigeration units…More

Stainless steel is resistant, but certainly not immune, to corrosion. In a previous article, we examined the need for inspecting stainless steel pipes further, including a discussion of conditions which encourage corrosion. When corrosion does occur in stainless steel, the corrosion often manifests in a very localized manner rather than uniform (or “general”) corrosion. Two forms of corrosion particularly troublesome to stainless steel are pitting and stress corrosion cracking, and both can cause very bad problems. Thus, for stainless steel piping systems, corrosion is an issue worthy of the attention of plant managers…More

Spray drying is the process of converting a mixture in its liquid form to a powder. This is done by removing the moisture component from the liquid solution. The solution, sometimes called an emulsion, is sprayed through a nozzle into a chamber that simultaneously has hot air being blown into it. This is the preferred method of drying of many thermally-sensitive materials such as foods and pharmaceuticals.

Thermaxx Jackets has worked with many clients who are trying to make their food processing plant more energy efficient, safer, and cleaner (such as Calabro Cheese). The USDA recommends insulating pipes in food processing facilities, providing a layer of protection between the piping and your product. The insulation blankets used should be food grade or food safe. “Food grade” or “food safe” means that the insulation jacket designers consider the particular needs of the food processing plant.

A question that we are commonly asked is, “How long will these insulation jackets last?” That is a good question with several answers! Materials play a huge part in the life cycle of an insulation jacket. Choosing the correct hot and cold side cover is key in getting the optimal lifespan of an insulation jacket. The first thing we need to look at is the location: is it in a chemical plant, power plant, high acidity area, or an isolated area in the middle of nowhere? Read more!

Thermaxx Jackets manufactures jackets for virtually all types of industrial applications. Many of our customers request waterproof and/or fireproof jackets/blankets for their facilities. When choosing insulation material for fireproof applications it is important to consider application type, surrounding environment and ASTM standards when choosing materials… More
