n: calcium carbonate, CaCO3

n: CaCO3, a natural calcium carbonate. Its relative density is from 2.6 to 2.8. A kind of heavy loader.

calcium carbonate, CaCO3. May be rock (limestone) or a scale formed from super saturated solution at the site of a chemical or physical upset.

n: a tubular section of pipe that is threaded inside and used to connect two joints of casing.

n: The short string whose two ends have the same type of tooth with casing. Used to connect casing.

the threaded connection, almost always upset to the outside.

see External Upset.

abbr: external upset end.

n: the joint whose outer diameter is same with the outer diameter of the drilling pipe and connected on the internally upset pipe

n: the circumstance in whichj the outer diameter of screw joint on the ends of the pipe is larger than the outer diameter of the pipe body

a pipe connection with a thicker connection body than the pipe body. In an EUE, the thickness is offset to the outside diameter.

n: refer toexternal upset

n: refer toexternal upset

n: (EVE) on tubing, casing, or drill pipe, the thickening at each end of the joint such that the internal diameter of the joint is not affected;i.e., it remains uniform throughout the joints length. Only the outside diameter is enlarged at each end. Pipe is thickened, or upset, at each end to increase its strength so that threads, couplings, or tool joints may be attached. Compare internal-external upset end, internal upset end.
