    Storage Information

    Handling And Storage

    • Triethylene glycol (TEG) is a stable. non - corrosive chemical with high flash point. Since it is hygroscopic. storage vessels must be designed to minimize moisture pickup. Other possible contaminants are iron and oxygen. For longer - term storage. or where iron contamination and color are objectionable. resin linings or stainless steel and aluminum vessels are recommended. Linings based on phenolic and epoxy resins are satisfactory. Zinc or zinc alloys should not be used in glycol service. For longer - term color stability. it is recommended that the product be stored under an inert atmosphere.
    • Cast - iron or centrifugal pumps with stainless shafts and impellers are satisfactory. Rubber - lined or rubber - bound gaskets should be avoided. Flexible graphite filled or stainless steel double - jacketed gaskets are usually effective larger gaskets. Stainless steel winding with flexible graphite filler piping gaskets performs well. Pipe thread lubricants based on corrosion inhibiting zinc compounds or a graphite based lubricant with aluminum are generally satisfactory; however. glycols are excellent penetrants and leaks may be present where hydrostatic testing has indicated a tight system. Therefore. the system should be rechecked after the glycol has been added.
    • Low pressure stainless steel steam coils in storage tanks and steam tracing of transfer lines may need to be provided in cases where low environmental temperatures may make pumping of the product difficult. Transfer or storage tanks can be readily cleaned by flushing with water and steam.

    Shelf Life

    • We define Shelf Life in terms of a product's conformance to sales specifications after a specified period of time. Using this as a guide. the product should retain its conformance to sales specifications for a period of at least two years from shipment. provided that the product is handled to minimize contact with air and is stored at less than 100°F in a suitable tank under a dry nitrogen blanket. However. the user should determine the suitability of any chemical compound. regardless of its shelf life or length of time of storage. It is the user's responsibility to conduct a sufficient investigation to establish the suitability of any product for its intended use.
