SCUBA REGULATOR MAINTENANCE AND REPAIR PDF

I have extensive experience in everything from visual inspections, compressor maintenance, dry suit repair, regulator servicing and more. As well as Whites dry suits service technician. Now that I have successfully bored you OR captured you with the short story of my position in the diving industry, I would like to get into the deep and dirty of this feature. Servicing your gear and why it is important? I will also be doing another feature in the near future about purchasing dive gear.

Servicing Scuba Equipment: An introduction All equipment used by divers underwater or for the provision of their breathing gases is fundamentally life support equipment. Scuba regulators, scuba tanks and compressors work at extremely high pressures and use innovative engineering design techniques to function correctly.

The service and repair of scuba equipment is not intuitive even for those with formal engineering training in other disciplines. Only formal training in the repair and maintenance of dive equipment such as that received during the ASSET approved Dive Industry Technicians Course DITC can ensure the continuing safe and reliable operation of life support equipment.

Servicing SCUBA regulators Only technicians who have attended recognised training should attempt to service a scuba regulator. Many diver deaths have been caused by amateur attempts of scuba regulator repair.

Additionally, original manufacturer scuba regulator spare parts, custom tools, parts diagrams solvents and greases must be used. All technical support from this web site is only made available formally trained service technicians.

Industry brand leaders such as Scubapro, Oceanic, Aqualung, Apeks, Mares, Poseidon, care about the safe reliable performance of their products.

All brand leaders set up extensive international networks of service centers with formally trained technicians to accomplish this task. The single piece non-welded cylinder, plus heat treatments results in strength many times that of the pure aluminium. Rough handling, corrosion, heat and many other factors can critically effect the strength and integrity of its construction.

The end result is an explosion, that usually occurs during refilling, killing the compressor operator and destroying the dive center. Inspection of scuba tanks is a hazardous activity. Technicians have had limbs amputated when trying to remove the valve from pressurized cylinders. The pillar valve plus the removal tool was jettisoned through his leg during a servicing action.

Thankfully no one else was injured. Millions of scuba tanks still in use are made of an obsolete aluminum alloy that suffer from Sustained Load Cracking. Cracks develop in the neck region that eventually causes the cylinder to explode. These older cylinders must be tested using NDT equipment. New Zealand recently banned cylinders made from this older T aluminum alloy — other countries are expected to follow suit soon. Steel scuba tanks — are they safer than aluminium?

In one example, a flooded steel cylinder exploded within just a few months. Corrosion can also use up the oxygen level in the tank causing death through hypoxia. A flooded steel scuba tank lying suffers accelerated corrosion caused by the high pressure of air in the tank. This leads to critical weakening of the cylinder wall sufficient to cause an explosion.
