Whether manual, automated, or  phased array , ultrasonic testing can help manufacturers of bars, tubes, and related metal products ensure product quality and customer satisfaction.   Ultrasonic non-destructive testing (NDT) is a well-established technique that uses high-frequency sound waves to locate cracks and other hidden defects in metals, composites, and plastics. In the metals industry, ultrasonic inspection is used not only to inspect finished parts, but also raw materials in the form of bars, blanks, and plates that are offered for further processing.   When used properly by qualified operators, ultrasonic non-destructive testing is fast and reliable, usually requires no preparation of the test piece other than wetting with an ultrasonic coupling agent or water, and has no specific safety hazards or regulatory licensing requirements associated with its use.     Phased Array Ultrasonic Automatic Testing Equipment For Bars Ultrasonic testing  uses sound waves at frequencies typic

Note: Each step in the  seafood production chain  has its importance, but they work together to create the best quality products for consumers. We will highlight each stop along the production chain to pull back the curtain and explain what happens there. We're starting with the processing plant, as that's the stop that both wild and farmed seafood go through.   What is a seafood processing plant?   Seafood processing plants, also known as plants or processors, are facilities in which a range of procedures are done to prepare wild-caught and/or farmed seafood for eventual retail and consumption.     As seafood is highly perishable, special care is needed to preserve it after harvesting – this is where plants come in. Some facilities have both seafood farms and plants connected, some are onboard fishing vessels, and some plants are standalone.   What happens at a seafood processing plant?   As there is huge variety in species of seafood consumed worldwide, there is no uniform pr

    The   hydraulic valve test bench   is testing equipment that integrates electromechanical, hydraulic, and liquid medium storage and circulation systems. It has perfect functions, stable performance, and a high degree of automation. It can be widely used for strength testing of various valves, and can also perform various performance  tests for valve  sealing and anti-leakage, providing various accurate data for industrial production. During the test, it uses the test pressure of the first valve as a reference to adjust the boost pressure of the tested valve. It is strictly forbidden to have an excessively high boost pressure to prevent the valve from being deformed and damaged. Before the hydraulic water supply pump starts to work, it is necessary to adjust the pressure of the electric contact pressure gauge and the valve under test to the same, and then start the operation. Due to the wide variety of valves on the market, the applications of valves in different industries are diff

    An  oil press machine   is a machine that extracts oil from seeds and nuts by pressing them. It consists of a motor, a pressing chamber, and a filter. The oil is extracted by mechanically pressing the seeds and nuts through a bore and then collecting the extracted oil. There are various types of oil press machines, including hydraulic press machines, screw press machines, and cold and hot press machines. The oil produced by an oil press machine is often used for cooking and can also be used as a natural ingredient in beauty products and other household items. The operation of an oil press machine is relatively simple. Here are the basic steps: 1.  First, the  oil press  machine must be properly prepared for operation. This includes adding the seeds or nuts to the pressing chamber and ensuring that the machine is properly lubricated. 2.  The  oil press  machine is then turned on, and the motor begins to rotate. As the motor rotates, it drives a series of gears that, in turn, press t

Gas insulated switchgear , commonly referred to as GIS, is a solid metal-enclosed device that contains a variety of high-voltage components, including   disconnecting switches   and   circuit breakers . These gadgets can be used in a very safe manner in limited areas, such as tight spaces. The main function of a GIS substation is to switch, separate, transform, measure and distribute electrical energy in the power system. The main feature of GIS equipment is the use of SF6, an inert gas with excellent insulating properties and chemical and thermal stability. In contrast, GIS units require only centimeters for effective insulation, whereas air-insulated switchgear requires instrumentation to perform the same function. All of these features make GIS a more reliable device than AIS, with fewer space and maintenance requirements.   How GIS Works Switchgear ​ using SF6 protects the power supply and distribution by interrupting the current in the circuit when necessary. Under normal conditio

AC and  DC welding ​ are arcs that use different currents to produce an arc forms of welding. These types of welding involve the creation of an electric arc between the electrode and the metal being welded. The arc provides heat to fuse the metal together. The power source is used to generate the arc and can be AC or DC. The choice of power source (AC or DC) determines the polarity of the current flowing through the electrodes. The power source used also affects the production of the weld. DC Welding DC stands for direct current, which flows in one direction. With DC welding, a stable arc is produced because the magnetic field and current of the arc are constant. And because the circuit must be continuous for the current to flow, we use a grounding clamp and electrode holder or TIG/MIG torch to complete the circuit. The arc jumps between the electrode and the metal with the grounding clip attached to complete the circuit.  Due to the resistance of the metal, the electrode and the metal
