Title Simple mechanical joints for dangerous substances?
Original title Einfache Gleitringdichtungen für gefährliche Medien? [in German]
Bibliographic information June 2001, Vol.31, No.6, p.42-44. Illus. 5 ref.
Abstract Mechanical joints used in chemical plants, refineries or storage tanks are important components of safe operations. They are generally reliable under normal conditions. However, in cases of failure, they could result in the leakage of important quantities of liquids, which depending on their nature could have serious consequences. A team from the University of Duisburg undertook to examine what would happen if mechanical joints were damaged. A test rig was built for this purpose, including a pump for submitting the joints to extreme conditions and to determine the volumes of leaked liquids. Trials were carried out with different types of joints. Results indicate that that mechanical joints are relatively reliable and even in cases where the joint surface is damaged, leakage volumes remain low.
