Hello everyone,
Just a quick question....is there any standard that prevents me from welding a threadolet/flexolet on the end of a welded cap or even limits the size of the tap as well? I've looked through some applicable standards but can't seem to find anything.
Thank you!
That's correct ESD compressor building trips...there would be 1-3 compressors in one building and 1-3 in another. I completely agree but I think we might stick to 30m just to be on the safe side and we have the room to do so.
I do but this is more of a question for a new facility being built. Is the one way to do this by calculating blast pressure? I realize this would be an accurate method...I guess I was just thinking there was some recommended practices when it came to this similar to what BigInch posted.
In effect yes that's what I'm asking. Well an ESD vents all the gas from inside the building during a possible gas leak inside the building or a fire. The question is how far would an adjacent compressor building need to be for it to be considered safe to run. Now I understand depending on the...
Can you tell me what book this is from? From what I can see here, the major oil company and Aramco states 3m for compressors? That is way too close...just 10 ft. The size of the building alone will be much larger. I was thinking around 100ft would work but I really have no basis for it.
Yes I am aware of that but we have determined that "station gas piping" is limited to the compressor building and the headers associated with that building, excluding yard piping. We have several sites where we implement this logic and the state public service commission understands this. My...
Is there a guideline (maybe from AGA) that provides requirements for the minimum distance between two compressor buildings so that they can still utilize the same ESD system? For example if there are 3 compressor buildings in the same facility, what is the minimum distance they can be from each...
That was a good reference littleinch...do you have direct link to that article?
Looks like it gets as close as we can to the answer. Looks obvious to me it was just a number out of thin air that the committee picked
This is just a general question but where do the requirements for the class location originate from? So for example, a class 1 is intended for 10 or fewer buildings or dwellings. My question is why is it 10 and not 11 or no? Who made the decision that it was 10 for class 1 and 46 for class 2, etc?
Any response to the second portion? This is my main concern as we have a few places where we are having this issue and I don't want to go down the road of mechanical connection if I don't have to.
Hi guys
We're having some issues with the inability to fuse HDPE pipe which has been attributed to the natural gas quality, specifically hydrocarbon liquids. These is indication of bubbling of the plastic after preheat making it difficult to get a high quality fusion. I've done some research...
Last night we had a small incident at one of our station and I was looking to see if anyone else has seen this before. A filter separator was left over night to air out before the filters were changed. When operations got on site they saw a fire around the door of the vessel and had to put it...
Has anyone ran into any charts that show this? I've just seen EG/TEG/NaCl/NaCl2 with water. Any help would be appreciated. I'd like to see something showing how temperature affects this.
Thanks guys!
