Propylene glycol is a colourless and viscous liquid with nearly no odour. Amongst its many uses, propylene glycol can prove an effective product for use in heat exchangers and hydrotesting applications. In hydrotesting, propylene glycol serves as an anti-freeze for piping systems and equipment that is useful in temperatures below -40°C. Ethylene glycol was widely used in the hydrotesting industry in the past, but many companies are now using propylene glycol because it is more environmentally friendly. Propylene glycol has medium viscosity so it is easy to apply and its toxicity and vapor pressure are lower than alternatives like ethylene glycol, making it ideal for hydrotesting.
Hydrotesting determines the strength of pressure vessels like fuel tanks, boilers, gas cylinders, pipelines, and plumbing. It is used to test for leaks and other malfunctions in the pipe or equipment. Propylene glycol is an efficient hydrotesting fluid that will keep from freezing in sub zero temperatures.
Because of the many uses and users of propylene glycol, there is also differing demand for various grades, delivery methods, and blends. Propylene glycol for hydrotesting applications can be supplied in tech grade or as a recycled product depending on the customers need. Blends of inhibitor, dye, or water in conventional storage vessels (i.e. bulk, totes, pails, and drums) are easily processed to suit any application.
Propylene glycol is hygroscopic, water soluble, and non-corrosive, making it a good choice for hydrotesting fluid. As well, it is a safe deicer for aircraft and runways and an environmentally friendly antifreeze for vehicles. It is also used for winterizing plumbing systems in structures that have been left vacant. Propylene glycol has a low freezing point comparable to ethylene glycol, but it is a safer solution and is also non-toxic.
