【 摘 要 】
The transfer line is one of the important components of any cryogenic system needed to transport the cryogenic fluid from one location to another. Towards our efforts to develop a long rigid-type transfer line for liquid nitrogen (LN2) to transfer this fluid from a 5000 litre capacity vertical storage tank to the Helium liquefier (Linde Model 1610) located at a distance of nearly 50 m, we designed and fabricated several units of straight section transfer lines of length ≈ 6.5 m and they were integrated to make the long length transfer line. Each unit was fabricated with 0.5 inch dia. copper inner tube supported by spacers within 2 inch dia. PVC outer tube. Each section was foam insulated after the necessary instrumentation for temperature measurements. The individual sub units were integrated together with a small bellow section in between to take care of thermal contraction during use. We present here the analytical and experimental studies of the cool down and mass flow characteristics of a single foam insulated unit. These experimental studies are representative results of the performances of the long length rigid foam insulated transfer line.
