Confining Pressure Influenced Tungsten Carbide Porous Nozzle

Confining pressure refers to the isobaric stress state, which the three main stresses is equal at any point. It is also known as hydrostatic pressure or hydrostatic pressure and also called static rock pressure or geostationary pressure in the earth. The drilling confining pressure generally refers to the stress, which works uniformly on the horizontal of the rocks. In rock mechanics test, the major part is to test surrounding fluid pressure. In oil well drilling engineering, the horizontal stress after decomposability is called confining pressure. Some related experimental statistics shows that with the increasing confining pressure, the broken volume of rocks is decreasing, and the cracking ability of single-hole nozzle is better than porous nozzle.

Halvers Tungsten Dart Rule

Halvers tungsten dart rule is a fun game for 2 players or teams.

The Object: To get a higher score than the other team.

The Scoring: One player from each team throws at bulls-eye, closest to the bulls-eye plays first.

The Play: Each team throws three darts to try and attain the highest score based on the target listed in the scoreboard each round. The rounds are played in order listed on the scoreboard and only the targets described for that particular round count. The thin outer "doubles" ring counts as two times the number hit and the thin inner "triples" ring counts as three.

The rounds 20, 19, 18, 17, 16, 15, 14, 25 and 50 mean to aim for the number specified. For example during the 20's round only darts in the 20 count, etc. 25 means single bulls ONLY, doubles do not count. 50 means double bulls ONLY, singles do not count.

The remaining rounds are as follows:
T = Triples round, any triples count.
D = Doubles round, any doubles count.
3C = 3 Colors round. Each dart must land in a different COLOR on the board.
H = Hurdles round. The first dart is thrown anywhere on the board and the next darts must "hurdle" a number clockwise. For example, the first dart is thrown into the 20, the next dart has to hit the 18 to count and the next dart has to hit the 13 to count. These darts must be in order.

If all three darts miss the target number, your previous score is cut in half, hence the name of the game. For example, in the first round you throw two single-20's for a score of 40. In the next round, you miss the 19's, your total score would now be 20.

Strategy: Be careful when you get to the 25 & 50 sections of the game, those bulls can be elusive and missing them can quickly kill a big lead!

How to Remove the Broken Tungsten Dart Tip Out of Dartboard

Tungsten darts is a fun game that can be played alone or in a group. There are hundreds of tungsten dart games that can be played for fun, though some people do it professionally for a profit. No matter how expensive or sturdy your dartboard is, if you have soft-tip darts, occasionally those tips are going to break off into the board. If you don't clear those tips out, they can prevent tungsten darts from sticking properly in the board. It is best to remove the broken tip out of the dartboard as soon as possible. The instructions of how to remove the broken tungsten dart tip out of dartboard:

1. Pull the tip out with a dartboard repair tool, if available. The tip of the tool makes it easy to grip the broken tip and pull it out because it has an edge specifically made for this one task.

2. Grip the broken tip with a pair of needle-nose pliers if you don't have a special dartboard repair tool. If the broken tip is at least 1/8th of an inch long, this should be easy to remove with the pliers.

3. Push the broken tip through the surface of the dartboard if it is less than 1/8th of an inch thick. There is a small gap between the board and the scoring wedges that allows for tiny tips like these to fall through without a problem.

4. Unfold one end of a paper clip and use the tip to gently remove the broken tungsten dart tip from the dartboard. This is the way to go if you don't have a special dartboard repair tool and also don't have a pair of needle-nose pliers handy.

How to Play Cut Throat in Tungsten Darts

Cut throat is a variety of cricket, a popular and fun tungsten dart game. Whether or not you are already familiar with the rules of cricket, if you follow the steps below you will soon be an expert at cut throat--at the rules at least. Steps about how to play Cut Throat in tungsten darts are as followed:

1. Decide upon your strategy. In cricket, each player works toward getting three marks in each number 15 through 20, as well as the bulls-eye. A double counts as two marks and a triple as three. Once a player got three marks for number, that number is "closed." You will want to work toward closing all your numbers in whatever manner best suits your style of play.

2. Keep score of your hits. Traditionally this is done with a chalkboard hung near the dartboard. An electronic dartboard will often take care of this for you. If you do have to score on your own, the traditional manner in which to do so is to write the numbers down the side of the board and the names of the players (or teams) at the top. The first hit of any number is designated by a diagonal line under the name and in line with the number. With the second hit this diagonal line is turned into an X. Finally, for the third hit, draw a circle around the X.

3. Determine who goes first and begin the game, alternating turns with each player taking three shots at a time. Record any hits accordingly.

4. Try not to hit any number once you have closed it. This is the key to cut throat. In other styles of cricket, hitting a number you have closed is desirable, as it gives you points and you need the most points--in addition to closing out every number--to win. In cut throat, however, you do not want to score points because instead of earning them yourself they are given to any opponent who has not also closed out the number.

5. Record any points scored and remember that once every player (or team) has closed out a particular number no more points can be scored by hitting it. For example, if all players have closed the 20 and you hit it, no points are accrued.

6. Score more points than your opponent(s) to win and you must close out all the numbers 15-20, as well as the bulls-eye.
