Instrumentation tubing is the method that many industries use to connect the several different pressure gauges or switches from their equipment, as well as various flow monitors and valves in ventilation systems and industrial piping. There are several materials that the tubing can be manufactured from, the most common ones being stainless, mild steel, aluminium and copper, and various sizes, depending on the outside diameter, although most industries often use the 1/4”, 1/2” and 3/8” ones. In this tubing field, Tungum is a widely known material, used in many industries, including the oil and gas production, the transportation industry, the medical field and even the marine industry, as it is highly efficient and durable. In fact, this material is an alloy of bronze and copper, with a layer of passive oxide that grants it an extremely thin coating when the material is exposed to reagents. The high resistance of the material is just one of its many advantages, stress and crevice corrosion within the marine environments having nothing against this alloy. Therefore, Tungum delivers an incredible service life, even if it is not used constantly and has long periods of discontinuous or sporadic use.
When it comes to instrumentation tubing, this bronze and copper alloy is clearly the best choice, its non sparking and non magnetic properties making it perfect for high pressure systems, such as gas pipework ones, whether inert gases or oxygen, because there is no electrostatic discharge. In some particular cases, Tungum can be hardened under precipitation, which means specific heat treatments are applied. This is very uncommon among other types of copper alloys and very advantageous, as the physical properties can be adjusted this way to specific needs, becoming suitable for a larger variety of applications, including cryogenic ones, meaning at very low temperatures. Among the other advantages of this alloy widely used in instrumentation tubing, good ductility can be mentioned, as well as top class fatigue properties and an astonishing high ratio of strength to weight.
All of the above mentioned features and characteristics, make the copper and bronze alloy a perfect choice for pneumatic circuits or high pressure hydraulic ones, becoming part of a well constructed and high integrity system. Therefore, no external protection will be required for the instrumentation tubing scheme. Tungum is a hugely popular material in the marine industry, because it resists very well to sea water and the atmosphere within. It is also a favourite for oxygen piping, due to its thermal conductivity features, as it has the ability to cancel the dangers of employing lesser materials. In chemical engineering, the alloy is a perfect fit because it can be used in very low temperatures and has a high corrosion resistance, which is often needed when working with gases that contain corrosive elements or with conveying fluids.
Taking everything into account, when it comes to connecting gauges, valves or switches in different piping and ventilation systems within various industries, the bronze and copper alloy called Tungum is the best choice, giving experts a lot of usage room and a series of invaluable benefits.
