Have you ever had an RFQ asking for a X-mas tree valve? And how are they related to the oil field? Here are some interesting facts about them;
“-Most oil wells have two pipes that extend to the area where the oil and gas are located. One is the outer pipe called the production casing. It seals the well bore from all the outside dirt, rock and other stuff that the well is drilled through. There is a second pipe that the oil and gas runs through to get from the bottom of the well to the surface”.
-In simpler words; the Christmas tree is a valve assemble that is designed to fit on the casing and attach to the tubing so the well and be controlled, maintained and worked on. For those of us that wonder what they look like out in the field; here is a picture of one I found on the web.
