Corrosion is another major issue in chilled water systems that can lead to equipment damage and unscheduled downtime. The presence of dissolved oxygen, carbon dioxide, and chlorides can exacerbate corrosion processes. To mitigate this risk, corrosion inhibitors, such as nitrites, phosphates, or azoles, are added to the chilled water. These inhibitors form a protective film on the metal surfaces, effectively shielding them from corrosive agents. Implementing a tailored chemical treatment program not only prevents corrosion but can also extend the lifespan of the system components.

EGDF is considered a viscous liquid at room temperature, and it has a moderate boiling point. Its low volatility and relatively high thermal stability are advantageous in industrial applications, where temperature consistency is essential. Additionally, the compound is soluble in both polar and non-polar solvents, enhancing its utility across various chemical processes.


Drug intermediates play a crucial role in the pharmaceutical industry, serving as essential building blocks in the synthesis of active pharmaceutical ingredients (APIs). These intermediates are not intended for direct therapeutic use; instead, they are chemical compounds that undergo further transformations to produce final drug products. The importance of drug intermediates cannot be understated, as they significantly influence both the efficiency and cost-effectiveness of drug development processes.

  • Top swing reversible windows are also mainly used in high-rise buildings, but they could be worth considering for the home. Essentially, these operate in precisely the same way as top-hung casement windows, but they use a very sophisticated friction-stay mechanism. The window is opened to its normal opening position and then stops as a standard opened window.  Upon releasing a catch on the friction stays, the window continues to open out still further and reverses back on itself, bringing the outside pane to the inside.

  • Today, it’s hard to find cast or wrought iron of any sort for structural purposes like fencing. The majority of what is produced is small or purely decorative ornamentation. In fact, the largest examples of iron you can easily find are large decorative wall panels. To create a pure cast iron fence, you would have to hire a skilled worker to weld pieces together into larger panels. This will be expensive, take a lot of time, and the final product would still likely depend on steel top and bottom rails as well as posts for its strength. Wrought iron stock for rails and balusters is meant for limited use—mainly restoration work—and getting ahold of enough stock for a large residential fence is difficult, and stunningly expensive. The end result of all this effort would be a fence that is notably less durable than one built of cheaper and more widely available steel.

  • The most common method of welding wrought iron is oxy-acetylene welding, also known as gas welding. This process involves using a torch that mixes oxygen and acetylene gas to create a high-temperature flame that melts the wrought iron pieces together. The skill in gas welding wrought iron comes from controlling the temperature of the flame and the speed at which the pieces are joined. Too much heat can cause the wrought iron to become brittle and weak, while too little heat will not create a strong bond.
