12. Demaco recommends to use a straight line, even though a bended line may be convenient (stress distribution). This type of transfer line is common for manufacturers of transfer line. Straight transfer lines are more economical (30% less) than bended transfer lines. Safety assessment- measures are necessary to protect the line from excessive pressure during Loss of Insulating Vacuum (LIV). Safety valve locations in the 4K supply line and 4K suction line are critical (Safety Assessment – TL-NW) due to pressure loss in the TL. Vacuum barriers / safety valves are viable options for protecting transfer lines against LIV. Demaco recommends use of vacuum barriers with a reduced number of safety valves.
