WHA appliance for oil well logging

Since well logging always needs entering the earth as deeper as possible to get the

characterization of wells, high-performance logging facility is required, and it should be

heavy and firmer enough, so as to balance out much more upward resistance and enhance

the downward impulse force. In fact, it should just work as counterweight for the whole

part.

Tungsten heavy alloy (WHA) is an excellent casing material for down-hole logging of oil

wells. Casings must be sufficiently heavy to readily sink through materials such as barite

mud and strong enough to withstand the hydrostatic pressure of this harsh environment.

Most designs are highly machined for sensor and window positioning. Mechanical

properties are very significant to the survivability of these rather large components.

 

What is well logging?

Usually, when it comes to environmental or geotechnical studies about groundwater,

mineral, oil and gas exploitation, it is necessary to well logging for analyzing stratum

situation exactly when drilling boreholes.

Well logging is performed at various intervals during the drilling of the well and when the

total depth is drilled, which could range in depths from 300 m to 8000 m (1000 ft to

25,000 ft) or more.

Weights and Counterbalances for Aircrafts

Tungsten Heavy Alloys (WHAs) are the best choice when Designers in aerospace and defense industries require a material which combines high density, good

mechanical strength and which is easily machined.

The high density of WHAs makes it possible to significantly reduce the physical size of

components. This in turn, gives the benefit of greater control of weight distribution and

increases the sensitivity of controlling mechanisms. Where a large mass must be housed

within a restricted area, WHAs are the ideal material.

Advantages of Tungsten Alloy Fishing Weights/Sinkers

1. Small volume

High density make tungsten alloy fishing sinkers/weights smaller than the conventional lead fishing weights. It will be hung up far less with a tungsten sinker than with a lead sinker because of its smaller size.

2. Hard

It's harder than lead fishing weight. It will not be stuck in the jowl of the fish. So the shape will be maintained longer.

3. Strong wind resistance

As the high density of tungsten, the tungsten alloy fishing sinker makes your fishing easier. It is extremely sensitive and can actually help you "feel" what the bottom is made of and what your bait is bumping into, such as brush, rocks, mud, etc.

Tungsten fishing weights/eyes are an ideal, environment-friendly alternative to lead weights, which are toxic and increasingly being labeled an environmental hazard.

The main specifications are: drop type, bullet type, Circular tube type, ball type.

Tungsten Alloy Fishing Sinkers

The Fishing Sinkers are large proportion (> 18g/cc), small size. They are against strong wind, light into the water, sinking fast, and are the best alternative to lead sinkers. The Fishing Sinkers are best-selling in Europe, the United States and other developed countries.
Tungsten heavy alloy fishing sinker or tungsten alloy fishing weight is a weight used to force a lure or bait to increase its sink rate , anchoring ability, and casting distance. Tungsten heavy alloy fishing sinkers may be as small as 1/32 of an ounce for applications, even smaller for fly-fishing applications. They can get as large as several pounds or considerably more for deep-sea fishing. They are formed into nearly innumerable shapes for diverse fishing applications.Unlike lead, environmental concerns do not surround the usage of tungsten alloy fishing weight materials.

Theory of Tungsten Alloy Crankshaft Counterweight

It is generally knows to all that a rotating object will generate centripetal force which is an actual force or load generated perpendicular to the direction of rotation. In fact, the magnitude of the force increases exponentially with speed. Increase the speed, the force will expand to four times or more of the speed. The amount of imbalance and distance from the axis of rotation greatly influence the centripetal force created by a tungsten alloy crankshaft imbalance .As long as the amount of centripetal force is offset by an equal force in the opposite direction, an object will rotate with no vibration. For instance,tie a brick on each end of a yardstick and you can twirl it like a baton because the weight of one brick balances the other. If we’re talking about a flywheel, the flywheel will spin without wobbling as long as the weight is evenly distributed about the circumference. A heavy spot at any one point, however, will create a vibration because there’s no offsetting weight to balance out the centripetal force.  

Tungsten Alloy Counterweight for Sports

Tungsten alloy weights are an ideal, environmentally friendly alternative to lead weights, which are toxic and increasingly being labeled an environmental hazard. Tungsten weights are harder than steel and extremely dense, tungsten being on average 30 percent smaller than its lead counterpart. Tungsten weights are smaller than conventional weights, create twice the sound of lead weights and maintain their shape for longer. Tungsten is also used in the production of other fishing applications, such as tungsten alloy line cutters and tungsten powder coating for fishing lines tungsten pin fishing sink, tungsten pin fishing sink, tungsten half drop with h, tungsten fishing sinker, tungsten banana with golf, tungsten alloy ball sinker, tungsten jig, tungsten pagoda pin fishing, drop sinker with groove, drop sinker with hole, half drop sinker with golf, tungsten rod with hole, tungsten fish spoon, tungsten fish head sinker, tungsten alloy ball sinker, none-toxic tungsten high-, tungsten alloy ball,ect.

Tungsten Alloy Sailboats Counterweights

Ballast is used in sailboats to provide moment to resist the lateral forces on the sail. Insufficiently ballasted boats will tend to tip, or heel, excessively in high winds. Too much heel may result in the boat capsizing. When sailing vessels carried cargo, it was at times necessary to sail to a port with no cargo. In order to do this enough ballast of little or no value would be loaded to keep the vessel upright. Tungsten heavy alloy counterweights would then be discarded when the cargo was loaded.
On larger modern vessels, the keel is made of or filled with a high density material, such as lead. However, lead is not environmental-friendly, so owning to high density and non-toxic, tungsten heavy alloy is increasingly adopted in counterweighs for sailboat. By placing the weight as low as possible (often in a large bulb at the bottom of the keel) the maximum righting moment can be extracted from the given mass. Traditional forms of ballast carried inside the hull were stones or sand.

Tungsten Fishing Weight

Tungsten weights are an ideal, environment-friendly alternative to lead weights, which are toxic and increasingly being labeled an environmental hazard. Tungsten weights are harder than steel and extremely dense, tungsten being on average 30 percent smaller than its lead counterpart. Tungsten weights are smaller than conventional weights, create twice the sound of lead weights and maintain their shape for longer. Tungsten is also used in the production of other fishing applications, such as tungsten carbide line cutters and tungsten powder coating for fishing lines.

A fishing sinker or plummet is a weight used to force a lure or bait to increase its rate of sink, anchoring ability, and/or casting distance. Fishing sinkers may be as small as 1/32 of an ounce for applications in shallow water, even smaller for fly fishing applications, or as large as several pounds or considerably more for deep sea fishing. They are formed into nearly innumerable shapes for diverse fishing applications. Environmental concerns surround the usage of most fishing sinker materials.

A jig is a type of fishing lure that usually consisting of a lead sinker with a hook molded into it and usually covered by a soft body to attract fish. However, recently, tungsten alloy fishing weights (fishing sinkers) is becoming more and more popular among angles because it has the features of high density, small volume, and environmental friendly, and has been taking place of the lead sinker. Jigs are intended to create a jerky, vertical motion, as opposed to spinner baits which move through the water horizontally. The jig is very versatile and can be used in both salt water as well as fresh water. Many species are attracted to the lure which has made it popular amongst anglers for years.

The fishing sinker/ weight is made by rare metal - Tungsten, it is an ideal substitute of the lead fishing sinker. It's strong adhesive, semi-solid state, soft for a long term. Tungsten alloys concentrate maximum weight in the smallest possible space. They are more often to be used as counterweight in sporting field, such as fishing sinkers, golf weights, etc.

Tungsten Alloy Vibrator

People find tungsten heavy alloy is excellent material for making this component. Since the density of tungsten alloy is so high and the maximum density should be 18.6g/cm3. It is popular for the component needs great heaviness but small capacity, for example: the vibrating parts of and clock, etc.

Tungsten Alloy Crankshaft

Nowadays, modern engine is often made from special metal alloys, and much lighter than earlier engines. So the powder and performance of a modern engine are increased. Also, material for crankshaft has been improved, and tungsten alloy is more and more used as the material for crankshaft.

It is necessary to provide counterweights for the reciprocating mass of each piston and connecting rod to improve balance in engines, and these are typically cast as part of the crankshaft. Lead is cheap but the density is much lower than tungsten heavy alloy, and it is not environmental friendly, as for steel, tungsten heavy alloy are more than twice the density of it, so compared with other materials, tungsten heavy alloy is certainly considered t as the most appropriate crankshaft material for its properties as follows:

Small volume but high density
Excellent hardness
Superior wearing resistance
Good corrosion resistance
Wonderful Shock resistance
High melting point
High temperature resistance
Environmental friendly

Tungsten alloy racket weight

Tungsten alloy is right material for tennis rackets or the like to change the swing force and impact center known as the "sweet spot" on a tennis racket and more particularly relates to a snap-on weight that can be easily attached or removed.
All players have different swings and control of the racket although the swing fundamentals are the same. The intent is to make as square an impact with the ball as possible with the ball impacting as close as possible to the center of the tennis racket head known as the "sweet spot". But, size, weight, height, strength and other physical factors cause different players to alter the fundamental swing slightly causing "miss-hits" which in turn cause errors in the flight of the ball. A miss-hit, such as contacting the ball near the frame of the racket, will cause the ball to go in the direction different than where it is intended when the player swings.

Tungsten Alloy Brick

Tungsten heavy alloys generally are refractory metal, which have two-phase composites consisting of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloy is added Co、Mo、Cr, etc. It could be made as various shapes, such as rod, cube, block, brick, ring, etc.
Usually, tungsten alloy brick could be manufactured as the parts of military defense, extrusion die, some counterweights, such as yacht counterweights, vehicle counterweights, airplane counterweights, helicopter counterweights, boat counterweights, tank counterweights, etc.
