What is a "stinger"?

What is a "stinger"?

What is a "stinger"?

(OP)
Is it used for instrumentation in helium service?  What does such an item do?

RE: What is a "stinger"?

We have a "stinger" used in pumping out underground tanks.  

I guess the name "stinger" is used because the "nozzle" and catch  looks like a "stinger". I suppose we could have called it a "bayonet" too, but, stinger it is.

RE: What is a "stinger"?

A stinger is a long, vacuum jacketed tube and it's connected to a VJ hose with some other bayonete connection on the opposite end.  The stinger is inserted into a liquid helium dewar or cylinder, right to the bottom.  The cylinder is then pressurized to force the liquid out.  Generally, these are used to transfer liquid helium to an MRI magnet, though they can be used whenever you're trying to transfer liquid helium from a dewar to another container.

RE: What is a "stinger"?

Depends on where you are.

In the NYC subway shops, a stinger is a large diameter flexible electrical cable suspended from the ceiling.  The free end is temporarily attached to the pickup shoe that normally slides on the third rail, in order to provide 600VDC to move a subway car within the shop, where there are only two rails.

Just as in the animal world, you will regret touching a stinger.  Hence the name.

How about a shoulder-launched surface-to-air missile :>)

RE: What is a "stinger"?

It could be a part of a welder's equipment.

RE: What is a "stinger"?

I think shopper1732 has found his answer so here goes a humdinger.
With all the people involved with boilers, heaters, and furnaces the big one has been missed:

The evolution of a paint peeling hot spot on the skin of any of the above into glowing red metal can be the mother of all stingers.  

RE: What is a "stinger"?

It is also the mascott of the Columbus Bluejackets

RE: What is a "stinger"?

It is also the cradle on the back of a pipeline laybarge that assists the pipe into the S lay shape.
