A
- Age Hardening
- An aging process that increases hardness and strength.
- Alloy
- A metal containing two or more elements.
- Annealing
- The heating and cooling of steel to:
- remove stresses,
- alter physical, mechanical and metallurgical properties,
- increase corrosion resistance, or
- thermally treat steel prior to age hardening.
- ASTM
- American Society for Testing Materials.
- Austenitic
- a group of chromium-nickel stainless steels. These steels are non-magnetic in the annealed condition.
B
- Brinell
- hardness testing system which measures indentation of the tubular by using a standard weight, shaped point.
- BTC
- Buttress Threaded and Coupled. Applies for casing and tubing.
- Burst Pressure
- internal pressure that will cause a piece of tubular good to yield.
C
- Carbide
- a compound of metal and carbon.
- crossover
- coupling
- it is a short piece of pipe used to connect two other pieces of pipe of the same diameter.
D
- Destructive testing
- a set of mechanical tests performed on samples of tubing which results in the destruction of the samples. Example of destructive tests:
- tensile,
- yield,
- elongation,
- hardness,
- flatten,
- reverse bend
- burst
- Drift
- it is the minimum ID clearance verified by pulling a plunger (also called rabbit) of known and calibrated size through the whole length of the tubular good. This is a very critical dimension to consider is some other completion tool is planned to run through the tubing or casing.
E
- EUE
- External Upset Ends. It is a type of tubular good in which its ends have extra thickness to supply additional strength to the connections.
F
- Flush Joint pipe
- it is a pipe in which the outside diameter of the joint is the same as the outside diameter of connected pipe.
H
- Hardness
- are results of tests performed by a standard Rockwell Penetrator on tubular goods and recorded on the Rockwell "B" scale.
- Heat Number
- it is a number assigned to a particular melt of material for identification and product traceability.
- Hydrostatic testing
- it is a test where the tubular good is filled with water at a high pressure for a specified period of time to check for leaks.
I
- I.D.
- Inside Diameter of a tubular good.
N
- New VAM
- Versatile T & C connection for the majority of today's applications.
- nipple
- short length of pipe (<12") threaded on both ends.
- nominal (dimension)
- nominal dimension means a tubular dimension that is used as a reference not the actual measured dimension. Sizes refer to approximate ID, even though OD is the fixed dimension.
M
- Mechanical properties
- Characteristics of a tubular goods in response to externally applied forces. These mechanical properties are very important to consider during the assembly of a completion.
- Tensile Strength
- Yield Strength
- Elongation
- Hardness
- Modulus of Elasticity
- Modulus of Elasticity
- Stress per unit strain, measured in psi. The higher the number, the more rigid the item will be for a given load.
O
- O.D.
- Outside Diameter of a tubular.
P
- Pup Joint
R
- Rockwell Hardness
- relative resistance of a metal to indentation by a diamond cone, as expressed in hardness-scale units (A, B, C or G).
S
- Schedule
- numbers assigned to tubulars as function of their wall thicknesses.
- seamless
- tubular with no weld at any point of its the circumference.
- Sub
- a short coupling
T
- T&C
- threaded and coupled tubular. Pipes that were cut with only male threads (pin) and need couplings to join them.
- Tensile Strength
- it is the resistance that a steel tubular good offer when is being pulled apart.
V
- VAM TOP
- tubular designed for high performance in compression under combined loads.
- VAM ACE
- The ideal connection for All Critical Environments, especially designed for CRA materials.
Y
- Yield Strength
- it is the tensile stress required to produce permanent elongation of a steel tubular good.
