Propane Tanks IF you have pulled one, Ups, Downs r just good Advice? Thanks

yes. you must wear that stuff when loading at the rack. its a good idea to unload wearing that stuff also, but most of the tanks and places i got to there is noone around and no one to make me wear it while unloading. but you should wear it.

just like fozzy said, i also have gotten freeze burned by propane and i wasnt wearing my ppe while unloading, but i did have my big thick winter carrhartt coat on that day,and the propane froze right through it and buned my forearm. the fitting at the bulk head was leakiong when i opened my valve, like a dummy, i grabbed it and tried to tighten it up a little and that made it worse, just bad enough to let it leak on my coat for just a second, but thats all it take. ALWAYS be cautious when ya have even just a small leak. just a little movment of the hose or fitting can let that stuff shoot out of there. NEVER LOOK AT ANY OF THE HOSES or fittitngs directly. the propane will actually lay in there for a little while when ya unhook. it doesnt really run out like water.

good luck with the new spot hand. if you need any advice, never be scared to ask any questions in this business. what seems like a dumb question to ask may the have the answer behind it to save your life.

 

How are you going to get "liquid" back into your pump from a vapor line ? and what do you think goes through the pump ? Why do you think "bad" things can happen ? And vapor lines are not always at the top of the tank.

 

Only vapor travels through these pumps.. its not like the pumps that you pump liquid with.. if liquid hits this pump it would be like hitting an air compressor or engine cylinder
..

 

Just like any fitting will leak if you're standing right next to it.

 

Simply put, YOU don't know what you're talking about.

 

Really.. Gee I guess I could have been imagining the whole thing.. but we didn't pump liquid through these pumps... There was not even a way unless you got really inventive to hook liquid hoses to these pumps... so clearly you are just trying to look smart and just looking like a horses arse trying to cause trouble.. if you have some information for the poster, then post it.,,, if you want to simply hump someone leg to look like you know something.. go somewhere else and play with those who care about what you think.

 

I am not commenting on your imagination....I do this day in and day out for a living, I simply pointed out you were giving wrong information. You pump LIQUID to the customer bullet, and in return the customers bullet returns your transport VAPOR, it's that simple if everything is "normal" on delivery. The reason terminals can't load you with no pressure is 1) the B210 valve (pressure sensing valve will not allow their pump to start if there is in fact no pressure 2) if the pump did start, it would blow the seals in the terminals pump because there is no pressure in the transport to "push" against. 3) Pressure and/or temperature keep propane or Nh3 in a LIQUID state for storage and transport. Depending on the type to burner being fed, it's burned in either Vapor or Liquid form. I have seen rail cars unloaded by raising the vapor pressure to "push" the liquid out but not a standard road transport.

 

You do not pump liquid through the pump.. period... You pump pressure either into one side or the other to get the liquid to move.. the pump merely changes the pressure in the vessles.. If you want to pretend that you can run liquid through a compressor.. be my guest!

I hooked the liquid line to the bulkhead's liquid line and a vapor line to the bulkhead's vapor line to my pump / compressor) and then a line to the (my) tank ( I normally had two).. There was no means to even hook a liquid line to the pump. And generally the vapor lines are on the TOP of the tanks as if it were not.. it would be IN or UNDER LIQUID and therefore it would also instantly be a LIQUID LINE as there would be no way to clear the thing..

We pulled vapor off the customer tank to keep our pressure up and to keep their tank pressure down, when we were empty of LIQUID we reversed the pump, hooked the vapor line to the LIQUID side of the bulkhead and pumped the vapor off of the truck tank and into the liquid side of the customers tank so they got all of the product the ordered..

And the refineries sometimes HAVE to load a trailer with no pressure in them as when these tanks are serviced they are vacuumed for several days before the mechanics will go inside them. They simply prefer (and its normal) that the tank have pressure in it.

If you want to add to a discussion where a newbie who has never done this then great,, it should consist of more that just coming in here and trying make other people (who have also done this for a living) look stupid or imply that they do not know what they are talking about when they do.. Your equipment and methods may be different, you may have a different means of doing things.. but I'll guarantee you that I know what I'm talking about or would not be offering an opinion.

 

Liquid goes through the pump on a propane trailer, or bobtail.......
