Coil, английский
- To lay a line down in circular turns.
- A heat exchanger in the form of pipe or tubing in any of various configurations; fins may
- A device fitted into a woman’s uterus as a contraceptive
- To loop a line neatly so it can be stored, or a reel of line. come about. see tack. com pan ion way. the steps leading from the cockpit or deck to the cabin below.
- Бухта троса
- A certain quantity of rope laid up in ring fashion. the manner in which all ropes are disposed of on board ship for convenience of stowage. they are laid up round, one fake over another, or by concentric turns, termed flemish coil, forming but one tier, and lying flat on the deck, the end being in the middle of it, as a snake or worm coils itself.
- [1] to lay down a line in fakes. [2] to loop a line for storage. [3] anything arranged in concentric circles. [4] a standard 120-fathom length of line as purchased.
- One or more loops of a conducting material; a single coil may be an exciter and induce currents in the material, or it may be a detector or both simultaneously. 19.6 aerospace nondestructive testing
- Одна или несколько петель из проводящего материала; одна катушка может быть возбудителем и индуцировать токи в материале, или она может быть детектором, или и тем, и другим одновременно. 19.6 авиационный неразрушающий контроль
- One or more loops of a conducting material. a single coil may be an exciter and induce currents in the material, or a detector, or both simultaneously. coil, absolute: in electromagnetic testing, a coil that responds to the electromagnetic properties of that region of the test object within the magnetic field of the coil, without comparison to the response of a second coil at a different location on the same or similar material. compare coil, comparator; coil, differential. coil, bobbin: in electromagnetic testing, cylindrically wound absolute or differential probe useful for inspecting the inside diameter of tubular products. coil clearance, annular: in electromagnetic testing, mean radial distance between the inner diameter of an encircling coil assembly and test object surface. see also fill factor. coil clearance, probe: in electromagnetic testing, perpendicular distance between adjacent surfaces of the probe and test part. see liftoff.23 coil, comparator: in electromagnetic testing, two or more coils electrically connected in series opposition and arranged so that there is no mutual induction (coupling) between them. any electromagnetic condition that is not common to the test specimen and the standard will produce an imbalance in the system and thereby yield an indication. see also coil, differential.23 524 nondestructive testing overview coil, demagnetizing: in magnetic particle testing, solenoid or coil carrying the current for demagnetization. current waveform may be alternating for pass-through solenoids or a rectified current for a multiple-step downcycle demagnetization. some residual magnetization may remain in large parts magnetized with direct current or rectified current, but subsequently demagnetized with alternating current. see also direct current downcycle demagnetization. coil, differential: in electromagnetic testing, two or more physically adjacent and mutually coupled coils connected in series opposition such that an imbalance between them, causing a signal, will be produced only when the electromagnetic conditions are different in the regions beneath two of the coils. in contrast, comparator coils are not adjacent or mutually coupled. coil, encircling: in electromagnetic testing, a solenoid or coil assembly that surrounds the test object. such a coil is also called an annular coil, circumferential coil or feed-through coil.23 see also coil technique. coil, excitation: in electromagnetic testing, coil that carries the excitation current. also called primary coil or winding. compare coil, sensing. coil, horseshoe: in electromagnetic testing, probe coil in which the ferrite core of the coil is horseshoe shaped. also called a u shaped coil. coil, inside diameter: in electromagnetic testing, coil or coil assembly used for electromagnetic testing by insertion into the test piece, as with an inside probe for tubing. see also coil, bobbin.23 coil, pancake: in electromagnetic testing, probe coil whose axis is normal to the surface of the test material and whose length is not larger than the radius. coil, reference: in electromagnetic testing, the section of the coil assembly that excites or detects the electromagnetic field in the reference standard of a comparative system.23 coil, search: in electromagnetic testing, detection coil, usually smaller than the excitation coil. coil, sensing: in electromagnetic testing, coil that detects changes in the flow of eddy currents induced by an excitation coil; sensing and excitation coils can be one and the same. also called detector coil. compare coil, excitation.
Coil, английский

Coil drag, английский
A fishing tool designed to pick up pebbles, bits of iron, etc., from the bottom of a drill hole.
Coil fill factor, английский
Coil impedance (et), английский
The total opposition to current flow through a coil and is represented by the ratio of the coil voltage to the coil current. this impedance is affected by the material within the magnetic field generated by the coil and is sometimes used to measure eddy current response.

Coil shot, английский
- In magnetic particle testing, one instance of the coil technique, or one pulse of current in the coil technique. see also shot.
- Coil technique. one instance of the coil technique; one pulse of current in the coil technique.
Coil shot (mt), английский
A term used colloquially to indicate a shot of magnetizing current passed through a solenoid or coil surrounding a part, for the purpose of establishing a longitudinal field.
Coil size (et, mt), английский
The geometry or dimension of a coil; for example, length or diameter.
Completion, английский
- Завершение
- In the context of project financing, occurs after a completion test, when the project`s cash flows become the primary method of repayment. prior to completion, the primary source of repayment is usually from the sponsors or from the turnkey contractor.
- Used to describe all activities between drilling to casing point and putting the well to production. includes cleaning out the well bore, setting the casing and tubing, adding surface equipment, and perforating the casing.

Hydraulic pumping, английский
A pumping method that uses a downhole pump without sucker rods. specifically, two reciprocating hydraulic pumps are used; the first pump powers the second, production pump. single and double tubing strings can both be used to pump multiple wells from a main source. when a single string is used, power oil travels down the string to the pump, and a mix of power oil and fluid is returned through the casing tub annulus. when two strings are used, power oil travels down one string, while the other returns the exhaust and produced fluid.
Kelly bushing, английский
A long hollow steel bar that’s used to connect the upper end of a drill string. kelly bushing is a sleeve in the rotary table that allows the kelly to freely move up and down during drilling. kelly bushing also plays a part in the measurement of well depth, as well depth is measured from the kelly bushing, down to the bottom of the well.
