Kirjoittaja Aihe: Why Aluminum Bronze Valves Dominate Harsh Industrial Environments  (Luettu 8 kertaa)

Numerous small quantities of iron, nickel, manganese, or silicon are also included in this copper-based alloy, usually containing about 5 to 12% aluminum, to develop their mechanical properties in a form that is conducive to a destructive harsh condition, especially the effect of sea water, brines or any form of acidity.Get more news about aluminum bronze valve,you can vist our website!

What are the properties of aluminum bronze and their compositions

It is alloyed with copper to form a copper alloy with improved hardness and resistance to water. The aluminum bronze that is typically used for applications in valves is the primary product of the American Society for Testing and Materials specification, ASTM B148 C95800, which is widely appreciated for excellent castability, high tensile stress and great machining properties. With a high pressure rating and heavy duty load capability, aluminum bronze sets itself apart from the ordinary bronze or even some stainless steels.

Resistance to Erosion and Cavitation and Low Embrittlement when used in Turbulent Flow Environments

Aluminum bronze has been found to possess desirable thermal conductivity and the non-sparking characteristics. It therefore becomes the right kind for such places where explosions and fires are likely to occur such as on aircraft carriers.

Useful in many industries

Aluminum bronze valves are used widely for different purposes as follows:

•         Marine engineering: used for the seawater systems, ballast control, and sand cutting systems.

•         Oil & gas: In the offshore platforms and refineries, where the threat of corrosion reigns surpreme

•         Chemical processing: when handling corrosive fluids and gases

•         Power generation: principally cooling and steam lines

Gate valves, globe valves, check valves, ball valves and butterfly valves are all types of valves made of aluminum bronze. Even in the most demanding of conditions, these valves have a long, serviceable life span, and usually require only minimal maintenance.

Manufacturing and Customization

Producers, such as Erie Bronze & Aluminum, specialize in supplying custom aluminum bronze valve components directly to the consumer based on the requirements of those industries. The designs include flanged valve bodies, impellers, valve seats and valve covers. Every component is manufactured by precision casting and machining in accordance with the world’s toughest and strictest quality criteria, usually corresponding to the most demanding aerospace and military vibrations.

Problems and Issues to Consider

Other than the many positives, aluminum bronze also imposes various challenges such as:

•         High Cost: It is generally more expensive than standard bronze or iron based alloys

•         Difficulty in Machining: Due to its hardness, the machining process requires the use of specialized tools and techniques.

Some suppliers may not have ample stocks of aluminum bronze valves, not to mention heavily customized varieties of these valves

However, the long term benefits such as prevention of shutdowns, maintenance replacement requirements and security improvements, (if properly addressed), far outweigh the initial requirements (for capital and replacement).

Conclusion

Industries that function in highly erodible, high pressure and high temperatures areas, the best approach would be the application of aluminum bronze valves. Those three things, viz. corrosion resistance, power and flexibility, would have long determined the inevitable overlying of aluminum bronze valves in society. Based on growing technology and the obsession with manufacturing the better products, aluminum bronze as far as valves are concerned is most likely to remain in the top.
