REFRIGERANT PROPERTIES, REFRIGERATION CYCLES AND SI UNITS, Chapter 6: Somewhat different requirements apply to the various section of pipe, depending on the location and purpose served in the system. Industrial Computers and Embedded Systems, Material Handling and Packaging Equipment, Electrical and Electronic Contract Manufacturing, Chapter 1: MIL-C-3133C (MIL STD 670B) Grade SBE 3 . Its unique internal restrictor reduces liquid flow to a level below the capacity of the compressor. Consequently, it cannot be bent, compact or flared without fractures and cracks in the skin.
