A single fitting installed in a pipeline that either blanks off the pipe or allows a full flow passage of a liquid through the pipe is referred to as a __________.
ā¢ Pipe fittings vs couplings vs flanges in liquid cargo or piping systems ā¢ The difference between a permanent blank and a fitting that can both block and pass flow ā¢ What a spectacle flange (figure-8 blank) is used for in pipelines
ā¢ Which of these choices is specifically designed to provide BOTH a fully open position and a fully blanked (closed) position in one fitting? ā¢ Which items are mainly for connecting hoses/pipes quickly, and which are for sealing or isolating a section of pipe? ā¢ In cargo or machinery piping, what fitting allows you to positively isolate a line for maintenance and then restore full flow without removing the entire fitting?
ā¢ Identify which option is a type of flange used for isolation, not just connection ā¢ Consider which fitting has two different ends/sections: one that blocks flow and one that allows full flow ā¢ Eliminate any options that do NOT normally provide a visible, positive indication that the line is either fully blanked or fully open
