What would the hydro date be on these?
Hello Andrew, it will come with the current hydro. could be a few months old but it is usually the same month as when we place the order for this. If you have any other questions or would like to place an order please feel free to give us a call at 1.800.347.2822.
I dive with steel 120s. How much less weight should I use for the steel 149?
It is impossible to say. There are too many factors involved such as suit type, thickness, body size, the tank you are using now, the water you're diving in and such. Compare the empty buoyancy characteristics to this tank empty and the tank you typically use empty, and that will give you the buoyancy different at the end of your dive. That is normally a good indicator of how much lead you can adjust.
How Your Faber Cylinders Are Designed,
Approved and Tested
Faber's Diving Cylinders comply with the most stringent specifications set down by International Bodies and Local Authorities.
The world over Faber is well known for its comprehensive range of safe Diving Cylinders, made to approved standards.
A list of Faber's Approvals for all types of cylinders is available.
On the following pages you will find an introduction to the design, the approval and the production tests which Faber's Diving Cylinders undergo.
1. The material (steel plate) is carefully selected depending on its eventual use conditions, after verifying the chemical, physical, mechanical characteristics.
2. The design of Faber cylinders uses not only specified calculation formulae but also linear finite element analysis. The calculated data are then verified experimentally using strain-gauge measurements.
3. The fracture mechanics analysis of the steel allows us to define the maximum permissible defects in the cylinders, in order to enable us:
- to establish the non-destructive tests during production
- to guarantee the product fatigue life
- to demonstrate that a leak precedes the hypothetical burst of the cylinder (LBB)
4. The cylinders' surface protection is considered to be a function of the various environmental conditions of use and of the various corrosion agents.
5. Faber's cylinders are manufactured according to a quality control program certified to ISO 9001 and ISO / TS 16949 (where applicable).
Design Tests and Analyses are performed for new design approvals of diving cylinders:
- On materials
- Mechanical tests: tensile, elongation, impact, toughness, ductility, stress-cracking
- Chemical analysis
- On prototype cylinders (check of safety performances)
- Hydraulic burst test
- Pressure cycling test
- Ductility and impact resistance test
- Environmental test
- Extreme temperatures monotonic and cycling tests
- Flawed cylinder burst test
During production all the cylinders are subject to:
- Hardness test
- Ultrasonic inspection
- Hydraulic (proof and volumetric expansion) if required by the standard tests
- Leak test on spun cylinders
- Check of the critical dimensions and of the threads
- Check of the marking
- Check of the specified internal and external surface finish
- Flawed cylinders burst-test
