What do run, shouldered, closed drain, cold flare blow down mean?
Thread Content
Hello everyone. I would like to ask: does the term \"run\" for valves (measured in millimeters) refer to the stroke of the valve’s operation? What does \"shouldered\" mean in the term \"shouldered anti blow out stem\"? What do \"closed drain\" and \"cold flare blow down\" mean in the context of describing service conditions of a system? Thank you!
shouldered: with shoulders
Closed drain: a system for sealed waste discharge/bleeding. Cold flare blowdown: waste discharge/bleeding through a cold flare; in our projects, a cold flare refers to a situation where the temperature of the fluid is below –48 degrees, requiring the use of stainless steel for the pipes.
Agree with the third floor’s opinion. \"Closed drain\" means that the discharge process is isolated from the outside atmosphere (except at the end point). \"Cold flare blowdown\" refers to the discharge of gas through a flame (cold). As for \"run\": is it a term used in mechanical processing, referring to a thin layer, that is, 0.01 mm?
