  1. Open tube

    Merge Acoustic resonance date May 2009 In the field of acoustics , a tone is created by the periodic vibrations of air. There are several ways in music to create such vibrations. One of these is to use a tube and to blow across the end. This creates a note of a given frequency, depending on the length of the tube and the pressure of the air. An open tube is a tube in which both ends are open. The tube Resonance resonates at a single fundamental frequency or note. An open tube Resonance resonates at the same frequency as a closed tube of half its length. In an open tube , an antinode always appears at each open end. By overblowing an open tube , a note is obtained that is an octave above the fundamental note of the tube. For example , if the fundamental note of an open pipe is c1, then overblowing the pipe gives c2, which is an octave above c1. References Jaap Kool Kool, Jaap , Das Saxophon . J. J.

Tube Tools can be categorized into function by application Tube Cleaners tube cleaning demands vary widely by application Shell and tube heat exchanger s and chiller s Deposits are typically sediment ... out residual deposits. Tube Testers Use air pressure or vacuum to test for leaks, cracks, and material failures in a tube. Both manual activated and air activated models are available. To test for leaks in tubes, two operators are required with an operator at each end of the vessel. Step 1 Seal the tube at both ends. Step 2 Build air pressure or vacuum in the tube. Step 3 Observe gauge to see if air pressure is dropping or vacuum is not holding. Tube Plugs Repair To regain efficiency of a heat exchanger or chiller, tube plugs are installed to take leaky tubes out of service. The rule of thumb ... that is the same as or a compatible material to the tube and tube sheet. Puncture the leaky tube using a one revolution tube cutter to relieve back pressure. Some contractors weld the tube plugs to the tube sheet after they are installed to permanently secure the plugs in place. Tube Removers One or a combination of the three below methods is used to remove a tube from a boiler or chiller vessel Tube Cutters Tube Cutters are used to internally cut from the inside to the outside of the tube behind the tube sheet on one end. This lessens the force required to pull a tube. To eliminate tube cutting chips in the vessel, tubes should be scored and not totally cut through. The tube cutter needs to have sufficient reach to cut behind the tube sheet. Proper lubrication and cutting speed will increase cutting blade life. Tube Pullers Used to break the seal and pull expanded tubes from a tube sheet. A spear or expanding collet is inserted and engaged into the tube inner diameter. A ram or gun applies force to exert an extracting force on the tube. The power to pull the tube is generated manually ...   more details



  1. Boiling tube

    image Test tube true C.png frame A boiling tube looks much like a test tube. A boiling tube is a small cylindrical vessel used to strongly heat substances in the flame of a Bunsen burner . A boiling tube is essentially a scaled up test tube , being about 50 larger. They are designed to be wide enough to allow substances to boil violently as opposed to a test tube, which is too narrow a boiling liquid can explode out of the end of test tubes when they are heated, as there is no room for bubbles of gas to escape independently of the surrounding liquid. Boiling tubes are made from borosilicate glass that can withstand high temperatures. ref cite web title Laboratory Glassware Types of Laboratory Tube url http www.thomasnet.com articles custom manufacturing fabricating laboratory glassware publisher ThomasNet ref References reflist Laboratory equipment DEFAULTSORT Boiling Tube Category Laboratory glassware ar es Tubo de ebullici n fa simple Boiling tube ta zh ...   more details

  1. Tube beading

    Tube beading is a metal forming process that forms a bead on the end of a Tubing material tube . Tube beads can be used to help hold a Hose tubing hose on the end of a tube or to strengthen the end of the tube. ref Gregory Miller, Tube Forming Processes A Comprehensive Guide, 2002, http books.google.com books?id s7aWW Jk9VgC . ref There are two forming processes internal roll forming and ram forming . Internal roll forming Internal roll forming is generally slower than ram forming but it holds tight tolerances. Serrated Clamp tool clamp jaws are used to hold the tube while an axial pressure is applied to the end of the tube to form the bead. Ram forming Ram forming is quicker and usually preferred when speed of production is a concern. The automotive industry usually uses this process over internal roll forming. A clamp is used to hold the tube, the tube is expanded to desired diameter by an expansion Punch metalworking punch , and then another punch is used to reduce the tube back to pilot diameter. Multiple beads are possible using this process. o ppikp References Reflist Category Metal forming metalworking stub ...   more details

    File Ignition Tube.png thumb An illustration of a setup using an ignition tube. The ignition tube is being heated by the Bunsen burner on the left, with the heated gas escaping from the tube to the pan via the delivery tube on top and at right. An ignition tube is a piece of laboratory equipment. It is a laboratory tube used much in the same way as a boiling tube except not being as large and thick walled. It is primarily used to hold small quantities of substances which are undergoing direct heating by a Bunsen burner or other heat source. Ignition tubes are used in the sodium fusion test . Ignition tubes are often difficult to clean due to the small bore. When used to heat substances strongly, some char may stick to the walls as well. They are usually disposable.

  1. Flux tube

    A flux tube is a generally tube like Cylinder geometry cylindrical region of space containing a magnetic field , such that the field at the side surfaces is parallel to those surfaces. Both the cross sectional area of the tube and the field contained may vary along the length of the tube, but the magnetic flux is always constant. As used in astrophysics , a flux tube generally has a larger magnetic field and other properties that differ from the surrounding space. They are commonly found around star s, including the Sun , which has many flux tubes of around 300 km diameter. Sunspot s are also associated with larger flux tubes of 2500 km diameter. Some planet s also have flux tubes. A well known example is the flux tube between Jupiter and its moon Io moon Io .

They were intended as single digit, simple displays, or as 4 or 6 digits by means of a special horizontal magnetic deflection system. Having only 3 electrode types a filament, an anode and 10 different grids , the driving circuit for this tube was very simple, and as the image was projected on the glass face, it allowed a much wider viewing angle than for example nixie tube s which Nimo tried to replace. ref http www.tube tester.com sites nixie dat arch BA0000 P31.pdf ref References references Category Cathode ray tube Category Television technology Category Vacuum tube displays electronics stub ...   more details
