Cylinders: Alu and Steel


As a SCUBA diving instructor, I have had the opportunity to work with both steel and aluminum SCUBA cylinders on a regular basis. Both types have their own unique pros and cons, and it ultimately comes down to personal preference and specific diving needs as to which one is best suited for an individual diver.

Steel SCUBA cylinders are known for their durability and strength. They are able to withstand higher pressures and are less likely to deform or crack under extreme conditions. This makes them an ideal choice for technical divers or those who may be diving in environments with rough or rocky conditions. They are also a good option for divers who plan on travelling with their gear, as steel cylinders are more resistant to damage during transport.

However, steel cylinders do have some drawbacks. They are typically heavier than aluminum cylinders, which can be a factor for divers who are concerned about weight and balance in the water. They also tend to be more expensive, both to purchase and to refill. Additionally, steel cylinders may rust over time if not properly maintained.

Aluminum SCUBA cylinders, on the other hand, are known for their lightweight design and lower price point. They are a popular choice for recreational divers who may not need the added durability of a steel cylinder. Aluminum cylinders are also easier to transport and handle, making them a convenient option for divers who may not have the same level of physical strength as their steel counterparts.

However, aluminum cylinders do have some limitations. They are not as durable as steel cylinders and are more prone to deformations or cracks under extreme conditions. They also have a lower pressure rating, meaning they may not be suitable for deep or technical dives. Comparing weight and size, for the same weight aluminum cylinders carry fewer litres of gas than steel.

Ultimately, the decision between a steel or aluminum SCUBA cylinder comes down to personal preference and specific diving needs. Both have their own unique benefits and drawbacks, and it is important for divers to consider their own diving goals and circumstances when making a decision. As a SCUBA diving instructor, I have worked with both types of cylinders and can confidently say that either can be a reliable and safe choice for diving.

Posso trasportare le mie bombole in auto? La risposta e'...

...ovviamente si! ma vediamo come e' disciplinato l'argomento e se ci sono accorgimenti particolari da tenere in considerazione. Nella mia macchina privata Un subacqueo può arrivare al sito di immersione in automobile e portarsi la bombola con aria compressa o nitrox, l’ossigeno di emergenza, l’argon per la muta stagna. Un privato che trasporta bombole subacquee caricate con aria, nitrox o argon per motivi personali (es. immersioni ricreative o ricariche) non è tenuto ad avere alcun documento di trasporto né etichette sul veicolo o sulla bombola. Deve solo trasportare la bombola in sicurezza nel portabagagli o sul pavimento del veicolo. La bombola non deve stare in posizione verticale ma incastrata tra i bagagli o dietro ai sedili per non farla rotolare di qua e di là. Su una macchina aziendale Le norme per le  aziende del settore subacqueo  sono diverse da quelle per i privati. C’è un limite di 1000 litri di volume totale di bombole di aria, nitrox, ossige...

Perchè li chiamiamo "BENDS"?

Immagine
In italiano sarebbe "La malattia dei cassoni", più comunemente definita come "Bends". Ma da dove deriva questo nome? La storia ci riporta agli inizi del '900, periodo nel quale operai dragavano il fondo di laghi, fiumi ed il mare con questi grossi cubi immersi in acqua e riempiti di aria compressa. Questi Cassoni avevano un grosso tubo nella parte superiore, denominato "camino" nel quale vi erano le scale per l'accesso alla parte immersa e per il pompaggio dell'aria compressa. Nella parte superiore vi era, di solito, una camera di compensazione. Il fondo invece era aperto per permettere la lavorazione. Come è semplice intuire, pur inconsapevolmente, tali operai erano del tutto soggetti alle stesse leggi che regolano l'attuale subacquea e quindi anche alla Malattia da Decompressione. Nel loro caso specifico, repentini cambi di pressione inducevano alla formazione di bolle nei tessuti dell'organismo, e proprio in quel periodo l...

Understanding the Forces of the Ocean: Current, Surge, Tide, Wave, and Swell

Immagine
Understanding the Forces of Ocean Currents Ocean currents are dynamic and powerful forces that shape our planet's oceans, influencing everything from climate patterns to marine life migration. At the heart of understanding ocean currents lies a complex interplay of various factors, including wind, temperature, salinity, and Earth's rotation. In this article, we delve deep into the mechanics behind ocean currents, exploring their origins, types, and impact on global ecosystems. Origins of Ocean Currents Ocean currents are primarily driven by two main factors: wind and density gradients. Surface currents, also known as wind-driven currents, are primarily influenced by the frictional drag of the wind on the ocean's surface. As winds blow across the water, they transfer their energy to the surface, creating movement and generating currents. These surface currents can travel vast distances and play a crucial role in redistributing heat around the globe. Below the surface, densit...
