Piezas especiales
El radio de curvatura será de, al menos, una vez el diámetro de la tubería, dependiendo del espacio disponible; se evitará en lo posible el uso de codos a 90C.
Las derivaciones se efectuarán siempre con el eje del ramal a 45 con respecto al eje de la tubería principal, salvo cuando el acoplamiento recto se necesite para equilibrar el circuito.
En los cambios de sección en tuberías horizontales los manguitos de reducción serán excéntricos y los tubos se enrasarán por la generatriz superior para evitar la formación de bolsas de aire.

Votes to reclassify question as PRO/non-PRO:

Non-PRO (2): Neil Ashby, philgoddard

When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.

How to tell the difference between "easy" and "pro" questions:

An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)

A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).

Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.

When deciding between easy and pro, err on the side of pro. Most questions will be pro.

* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

I have always assumed this was a direct translation.

eccentricity
1. n. [Drilling] ID: 1378

The term used to describe how off-center a pipe is within another pipe or the openhole. It is usually expressed as a percentage. A pipe would be considered to be fully (100%) eccentric if it were lying against the inside diameter of the enclosing pipe or hole. A pipe would be said to be concentric (0% eccentric) if it were perfectly centered in the outer pipe or hole. Eccentricity becomes important to the well designer in estimating casing wear, wear and tear on the drillstring, and the removal of cuttings from the low side of an inclined hole. In the latter case, if the drillpipe lies on the low side of the hole (100% eccentric), the eccentricity results in low-velocity fluid flow on the low side. Gravity pulls cuttings to the low side of the hole, building a bed of small rock chips on the low side of the hole known as a cuttings bed. This cuttings bed becomes difficult to clean out of the annulus and can lead to significant problems for the drilling operation if the pipe becomes stuck in the cuttings bed.

Eccentric - not having the same center; not concentric, such as an eccentric pipe
reducer, or an eccentric pump suction nozzle


Eccentricity (shaft) - The variation of a shaft surface at its outer diameter (OD)
when referenced to its true geometric centerline; a measure of a shaft's out-of-
roundness.

eccentric

noun
Definition
A machine element, situated to one side with reference to a center, that converts rotary motion to straight-line motion.
http://www.thefabricator.com/glossary/eccentric

Eccentric: Out of centre. A disk mounted out, of centre on a driving shaft and surrounded by a collar or a strap connected with a rod. Its purpose is to convert rotary motion into reciprocating rectilinear motion.

Eccentric Axis: An axis that does not pass through the centre of gravity or the centre of figure of the body considered. The axis about which an eccentric revolves.

Eccentric Gear: A gear wheel mounted with shaft out of centre.

Eccentric Load: A load which is applied to one side of the axis of resistance, and which, consequently, produces a bending moment on the piece considered.

Eccentric Rod: The main connecting link by which the motion of an eccentric is transformed and transferred.

Eccentric Strap: The band of iron or steel which embraces the circumference of the eccentric and in which it revolves.

Eccentricity: The state or condition of being eccentric. Deviation from a centre.

CONCENTRICITY

Used to describe tubing where the center of its inside diameter is consistent with the center of its outside diameter resulting in no variation of wall thickness. By virtue of the fact that welded tubing is fabricated from precision rolled flat stock, concentricity is inherent with a roll-formed, welded tube.

ECCENTRICITY
Opposite of concentricity, resulting in variations of wall thickness.
