A steel which owes its distinctive properties to elements other than carbon.
Area of a Circle
The measurement of the surface within a circle. To find the area of a circle,
multiply the product of the radius times the radius times Pi (3.142).
Braze Weld or Brazing
A process of joining metals using a nonferrous filler metal or alloy, the
melting point of which is higher than 800 degrees F(427 degrees C) but
lower than that of the metals to be joined.
A circumferential weld in pipe fusing the abutting pipe walls completely
from inside wall to outside wall.
A steel which owes its distinctive properties chiefly to the various percentages
of carbon (as distinguished from the other elements) which it contains.
Circumference of a Circle
The measurement around the perimeter of a circle. To find the circumference,
multiply Pi (3.142) by the diameter.
Coefficient of Expansion
A number indicating the degree of expansion or contraction of a substance.
The coefficient of expansion is not constant and varies with changes in
temperature. For linear expansion it is expressed as the change in length
of one unit of length of a substance having one degree rise in temperature.
The gradual destruction or alteration of a metal or alloy caused by direct
chemical attack or by electromechanical reaction.
The plastic flow of pipe within a system; the permanent set in metal caused
by stresses at high temperatures. Generally associated with a time rate
Diameter of a Circle
A straight line drawn through the center of a circle from one extreme edge
to the other. Equal to twice the radius.
The property of elongation, above the elastic limit, but under the tensile
strength. A measure of ductility is the percentage of elongation of the
fractured piece over its original length.
The greatest stress which a material can withstand without a permanent
deformation after release of the stress.
The gradual destruction of metal or other material by the abrasive action
of liquids, gases, solids or mixtures thereof
Radius of a Circle
A straight line drawn from the center to the extreme edge of a circle.
A fitting used to join pipe in which the pipe is inserted into the fitting.
A fillet weld is then made around the edge of the fitting and the outside
wall of the pipe.
A method of joining metals using fusable alloys, usually tin and lead,
having melting points under 700 degrees F(371 degrees C).
Change of shape or size of a body produced by the action of a stress.
The intensity of the internal, distributed forces which resist a change
in the form of a body. When external forces act on a body they are resisted
by reactions within the body which are termed stresses.
One that resists a force tending to crush a body.
One that resists a force tending to make one layer of a body slide across
One that resists a force tending to pull a body apart. Stress, Torsional:
One that resists forces tending to twist a body.
The maximum tensile stress which a material will develop. The tensile strength
is usually considered to be the load in pounds per square inch at which
a test specimen ruptures.
Any deviation from parallel flow in a pipe due to rough inner walls, obstructions
or directional changes.
Time rate of motion in a given direction and sense, usually expressed in
feet per second.
Volume of a Pipe
The measurement of the space within the walls of the pipe. To find the
volume of a pipe, multiply the length (or height) of the pipe by the product
of the inside radius times the inside radius times Pi (3.142).
A process of joining metals by heating until they are fused together, or
by heating and applying pressure until there is a plastic joining action.
Filler metal may or may not be used.
The stress at which a material exhibits a specified inciting permanent
