摘要

Double containment piping systems are used extensively for handling the conveyance of critical waste systems in industries such as Pharmaceuticals and biotechnology manufacturing and research. Often, these services involve the conveyance of critical fluids at elevated temperatures. An example would be in the discharge and transport of spent fermentation by-products in the biotech industry, where the vessel contents are sanitized by the addition of water at up to 210℉ and then discharged through double containment piping. Materials of construction used in such systems include thermoplastic, RTRP (fiberglass), stainless steel systems, and combinations thereof. This paper compares systems that are fully restrained by means of patented internal anchors designed to reduce stresses in components and evenly distribute the stresses to the secondary containment components. The systems are compared to the conventional methods of using thermoplastic systems restrained by unitary anchors. In addition to finite element analysis, physical tests are also performed to demonstrate the effectiveness of the conical shaped anchors.
