All About Brass Tubing

Friday, December 15th, 2017

It is an interesting matter to look for the different applications of brass tubing, where it starts from, how it is made, and how companies supply such metal products that people see on furniture and other household ornaments and fixtures.
Moreover, when you have a specific need for brass tubing, then it is even more interesting to explore this piece of metal furnishing. For starters, brass is not a pure metal, as most people believe. Brass is an alloy of copper and zinc. Being a combination of these two metals, it is more flexible than any other pure metals. It can be bent and formed for a particular use and designed. Frequently, it is coated with polyurethane or other protective solutions to protect its luster and surface from contaminants that may degrade its appearance, resulting from corrosion and tarnishing.
Brass is used in residential, commercial, and industrial applications. One of its good characteristics is its pliability, which owes to its very low melting point compared to other metals. It is an efficient and an inexpensive type of metal with a wide variety of practical uses.
And one of the most common applications of this metal is brass tubing. Brass Tubing is either available in all shapes and sizes, or can be ordered custom-build for a particular and unconventional use, such as for uniquely designed residential or commercial establishments.
On general use, Brass Tubing is used for bathroom fixtures and in all other necessary plumbing fixtures for bathrooms and kitchens. It can also be applied as decorative designs or ornaments in fine dining restaurants, classy bars, and five star hotels. Its shiny surface comparable to that of golds makes it elegant in appearance and draws the attention of both professional interior designers and ordinary people alike.
Brass tubing manufacturers and distributors can be found by referrals from relatives, friends, local hardware stores or other metal suppliers. It is good to contact local contractors as well. Business names and advertisements for these brass companies can be found in the Yellow Pages or in the classified advertisements of a local newspaper. You could also check the Web for web sites and referrals for Brass Tubing and manufacturers.

Some information About 18cm & 62cm Galileo Thermometers

Monday, April 11th, 2016

The Galileo thermometers were originally invented to measure the temperature of the surrounding. But, the introduction of 18cm and 62cm Galileo thermometers have completely shifted the focus of these devices from its functional use. These instruments were designed by scientists, keeping in mind the current trend and fashion of buyers. Earlier, these devices were not given any importance by the buyers and they were mostly used in laboratories for scientific purposes. But, the latest 62 cm and 18cm Galileo thermometers have grabbed attention of buyers all around the globe.

This is mainly because the 18cm Galileo thermometers have a very attractive appearance. As the name implies, they are 18cm long glass tubes. The most eye-catching feature of these items is the the colorful globes present inside the tube. These globes are always moving up and down in a playful manner. Majority of the individuals have agreed to the fact that the movement of the globes relaxes their mind after a hectic day at work. In reality, the playful movement of the colorful globes is caused by the change in the surrounding temperature. This is also true in the case of 62cm Galileo thermometers. The only difference is that the glass tube is 62cm long.

The 18cm and 62cm Galileo thermometers follow the principle of buoyancy like its predecessors. This means that the density of the liquid changes with temperature. Each of the colorful globes present inside the tube is filled with liquid of different density. When there is even a slight change in temperature, it causes the globes to either sink down or rise up to the surface. When they move up and down in the glass tube, it fills the whole room with a pleasing ambiance. This is one of the reasons why the 62cm and 18cm Galileo thermometers are more popular as a decorative item among buyers than for its functional use.

Since the 18cm Galileo thermometers have a very classy and elegant design, they are also very popular among gift givers. Their attractive appearance makes them appropriate gifts for any occasion be it birthday, anniversary or any special event. The best feature about these items is wherever it is placed; it will further enhance the beauty of the room.

Situation about Key Parts of China s Automotive Industry

Saturday, October 3rd, 2015

China’s automobile industry has gained a rapid development. In 2009, the annual output had reached 13.79 million. And China becomes one of world’s largest car producers. However, some key parts such as bearing bush, axes guide, thrust washers, and car mold standard parts mainly rely on imports which bring both the golden opportunities and great challenges to the Chinese bearing manufacturers and automotive mold manufacturing industries.

At present, China’s resource-saving bearing manufacturing technology which is the independent intellectual property is more material-saving and energy-saving than the conventional bi-metal bearing manufacturing technology. It requires less investment and less usage of equipments. Thus, it is an excellent opportunity for development. Until the end of the patent license of “Automotive mold self-lubricating composite metal embossing die V block” in 2009, China had completed the restructuring of the traditional and existing sintering bi-metal manufacturing technology of sliding bearing through twenty years’ accumulation and efforts. And then China realized the shape manufacturing of different bearing categories which made from the steel – copper alloys. There are bushing bearing, thrust bearing, sliding bearings with special shapes, and sliding bearings with solid lubrications, etc.

The rate of utilization of the steel and copper alloy materials has reached nearly one hundred percent. Since then, the manufacture of sliding bearings have changed from the rough shaping of the material removal into a net shape processing which has high efficiency, light weight, and low-cost and so on. The net shape manufacturing method helps to save materials and energy so as to provide sliding bearing accessories for the development of the China’s automotive industry.

Auto mold industry is known as “the mother of auto industry.” To some extent, the mold industry is the mark to measure the development level of the car manufacturer or even the national auto industry. Although through years of development, China auto mould technology and capability has made much progress, it still lags behind in the world automotive manufacturing industries. According to the statistics, about 90% of the auto molds are not “Made in China”. And the majority of the luxury car molds depend on imports.

There are many suggestions to follow: firstly, creating a resource-saving sliding bearing manufacturing industry with the independent intellectual property. It is not only in accordance with the national policies, but also in line with the policies for the key parts of China’s automobile industry development. Besides, it is an important choice for the development of the automotive parts manufacturing industry.

Secondly, we should seize the opportunity of domestication of the automotive parts to lay a solid base for the rise of our own auto brands. is the global B2B platform in the industry of mechanical parts. SeekPart aggregates the trade leads in this area, and our ultimate target is to benefit the buyers and sellers of mechanical parts by utilizing these leads through our online tools.

Something about Vacuum tube

Wednesday, June 24th, 2015

In electronics, a vacuum tube, electron tube (in North America), or thermionic valve (elsewhere, especially in Britain), reduced to simply “tube” or “valve” in everyday parlance, is a device that relies on the flow of electric current through a vacuum. Vacuum tubes may be used for rectification, amplification, switching, or similar processing or creation of electrical signals. Vacuum tubes rely on thermionic emission of electrons from a hot filament or cathode, that then travel through a vacuum toward the anode (commonly called the plate), which is held at a positive voltage relative to the cathode. Additional electrodes interposed between the cathode and anode can alter the current, giving the tube the ability to amplify and switch. recommend directory: 3528 SMD Flexible Strip with Non-waterproof 5 Meter 300 LEDS.

Vacuum tubes were critical to the development of electronic technology, which drove the expansion and commercialization of radio communication and broadcasting, television, radar, sound reproduction, large telephone networks, analog and digital computers, and industrial process control. Although some of these applications had counterparts using earlier technologies, such as the spark gap transmitter or mechanical computers, it was the invention of the triode vacuum tube and its capability of electronic amplification that made these technologies widespread and practical.

In most applications, vacuum tubes have been replaced by solid-state devices such as transistors and other semiconductor devices. Solid-state devices last much longer, and are smaller, more efficient, more reliable, and cheaper than equivalent vacuum tube devices. However, tubes still find particular uses where solid-state devices have not been developed or are not practical. Tubes are still produced for such applications and to replace those used in existing equipment such as high-power radio transmitters.

Vacuum tubes with two active elements (“diodes”) are used for rectification. Ones with 3 or more elements (“triodes”, “tetrodes”, etc.) are used for amplification, functions which rely on amplification such as oscillators, and switching.

Standard tubes with cathode, grids, and anode are classified in various ways according to requirements. They may be classified by frequency range (audio, radio, vhf, uhf, microwave), power rating (small-signal, audio power, high-power radio transmitting), design purpose (sharp versus remote cutoff; amplifying and switching, control and signal amplification, rectification, mixing, general-purpose versus very low microphonic and low noise audio amplification, and so on). Distinctions are not necessarily sharp; for example similar dual triodes can be used for audio preamplification and as flip-flops in computers, although linearity is important in the former case and long life in the latter.

Other tubes which could be called vacuum tubes have different construction and different functions, such as cathode ray tubes which create a beam of electrons for display purposes (such as the television picture tube) in addition to more specialized functions such as electron microscopy and electron beam lithography. X-ray tubes are also vacuum tubes. Phototubes and photomultipliers also rely on electron flow through a vacuum, though in this case the emission of electrons from the cathode depends on energy from photons rather than thermionic emission. Since these sorts of “vacuum tubes” have functions other than electronic amplification and rectification they are described in their own articles.

There are also varieties of current-conducting tubes filled with one or another gas at a higher or lower pressure; the common fluorescent bulb is a familiar example. Such discharge tubes and cold cathode tubes are not vacuum tubes and are not the subject of this article. However certain types such as the voltage regulator tube and thyristor physically resemble commercial vacuum tubes and fit in sockets designed for vacuum tubes. Their distinctive orange, red, or purple glow during operation betrays the presence of gas; electrons flowing in a vacuum do not produce light within that region. Although not properly termed vacuum tubes, they may still be referred to as “electron tubes” as they do perform electronic functions, and are briefly discussed below under “Special-purpose tubes.” recommend directory: 5050 SMD Flexible Strip with waterproof 5 Meter 150 LEDS.

A vacuum tube consists of two or more electrodes in a vacuum inside an airtight enclosure. Most tubes have glass envelopes, though ceramic and metal envelopes (atop insulating bases) have also been used. The electrodes are attached to leads which pass through the envelope via an airtight seal. On most tubes, the leads, in the form of pins, plug into a tube socket for easy replacement of the tube (tubes were by far the most common cause of failure in electronic equipment, and consumers were expected to be able to replace tubes themselves). Some tubes had an electrode terminating at a top cap which reduced interelectrode capacitance to improve high-frequency performance, kept a possibly very high plate voltage away from lower voltages, and could accommodate one more electrode than allowed by the base.

The earliest vacuum tubes resembled, and in fact evolved from incandescent light bulbs, containing a filament sealed in an evacuated glass envelope. When hot, the filament releases electrons into the vacuum, a process called thermionic emission. A second electrode, the anode or plate, will attract those electrons if it is at a more positive voltage. The result is a net flow of electrons from the filament to plate. However current cannot flow in the reverse direction because the plate is not heated and does not emit electrons. The filament (cathode) has a dual function: it emits electrons when heated; and, together with the plate, it creates an electric field due to the potential difference between them. Such a tube with only two electrodes is termed a diode, and is used for rectification. Since current can only pass in one direction, such a diode (or rectifier) will convert AC to pulsating DC. This can therefore be used in a DC power supply, and is also used as a demodulator of amplitude modulated (AM) radio signals and similar functions.

While early tubes used the directly-heated filament as the cathode, most (but not all) more modern tubes employed indirect heating. A separate element was used for the cathode. Inside the cathode, and electrically insulated from it, was the filament or heater. Thus the heater did not function as an electrode, but simply served to heat the cathode sufficiently for it to emit electrons by thermionic emission. This allowed all the tubes to be heated through a common circuit (which can as well be AC) while allowing each cathode to arrive at a voltage independently of the others, removing an unwelcome constraint on circuit design.

During operation, vacuum tubes require constant heating of the filament thus requiring considerable power even when amplifying signals at the microwatt level. In most amplifiers further power is consumed due to the quiescent current between the cathode and the anode (plate), resulting in heating of the plate. In a power amplifier, heating of the plate can be quite considerable; the tube can be destroyed if driven beyond its safe limits. Since the tube requires a vacuum to operate, convection cooling of the plate is not generally possible (except in special applications where the anode forms a part of the vacuum envelope; this is generally avoided due to the shock hazard from the anode voltage). Thus anode cooling occurs mainly through black-body radiation. recommend directory: 5050 SMD Flexible Strip with non-waterproof 5 Meter 300 LEDS.

Know more about Strain Gauge Load Cell

Tuesday, May 5th, 2015

According to the scientific definition, a load cell is an electronic device (a kind of transducer) that is primarily used to covert a force into an electric signal. Let’s take it simple. A load cell is simply a transducer which converts force into a measurable electrical output.

How a strain gauge load cell works? The manner in which the mechanical force gets converted into an electrical current is indirect and happens in two phases. A load cell can consist of one, two or four strain gauges depending on the type of cell, and it is the strain gauge that converts the force into the electrical current. Many people think that all load cells make the use of strain gauges but this is not true. There are different types of load cells such as hydraulic, pneumatic, fibre optic, button and washer load cells.

There could be many applications of the resulted electrical output. Well before the electrical current becomes usable the electric signal output typically requires amplification by an instrumentation amplifier and then it can be used. Strain gauge load cell is majorly used as a weighing apparatus. This is the reason why strain gauge load cell is widely used in carrying out various industrial weighing applications.

There are many applications where load cells are being used such as electronic crane scales, determining the centre of gravity of an object by weight, force measurement, force gauge, onboard weighing, railcar weighing, structural health monitoring, and tension measurement.

With the advancement in technologies, there are many new types of load cells available that are better used in certain applications and circumstance that others for example the new compression load cell is used for applications to tough environments. The new beam load cell is found to be perfect for belt scales, platform scales, filling machines, and process equipment. The single point load cell is typically used in applications such as multi-head weighers, check weighers, filling machines, belt scales, platform scales, and bench scales. The selection of a particular type of strain gauge load cell depends on your application requirements and the type of weighing you are doing.

Before the introduction of load cells, mechanical level scales were used. Mechanical level scales were effective only if they are precisely calibrated and maintained properly. The concept of mechanical level scale is to either use of a weight balancing system or the detection of the force developed by mechanical levers.
