130xs or 133faber which is better

PSTs.

The specs for the faber tanks are wrong. You put the faber at 7.65 positive at the end of the dive. It is negative .59 #. So it is negative and almost neutral when empty.

You put down the specs for a lp100 NOT the hp100 tank. So no rocks in the pockets needed.

Damnit Sorry about that....cross eyed columns. Great catch, and I am glad you caught it for correction

Weight (Empty)/Buoyancy(Full) /True Capacity/Length/Buoyancy(Empty)Diam.

Faber FX-133
Steel 3,442 psi / 42.7 lb / -9.08 lb / 133 cubic ft / 26.78 in / 1.45 lb / 8.02 in

Worthington-X8-130
Steel 3,442 psi / 43 lb / -11.7 lb / 130 cubic ft / 25.5 in / -2 lb / 8 in

Based on this info I would rather own the Worthingtons. I would not want a positive tank at the end of the dive. Especially if your properlly weighted (Weight Check with 500*PSI)

From Faber's website: "[FONT=Times New Roman, Times, serif]Faber has decided not to adopt the HDG process and has instead optimized its production cycle involving hot zinc spraying coupled with a primer + top coat of paint, which gives the best trade-off between corrosion resistance and an attractive appearance."

They do NOT hot dip galvanize. Zinc plating is NOT the same as galvanizing.

"[/FONT]What is the difference between zinc and galvanized? Both zinc plating and galvanizing applies a zinc plating. So they both use zinc. The big difference is in thickness, zinc plating is typically 3 microns thick. Hot dip galvanizing is 50 microns thick - so you get 10 times the protection with galvanizing."

And no where here does Faber say zinc spray is superior, they only say they optimized their production cycle.

For many years Faber had evaluated the possibility of hot dip galvanizing (HDG) its scuba diving cylinders. Extensive research has been carried out and many trials and tests have been performed in order to evaluate the industrial process and the performance of the coating in relation to the more commonly used hot zinc spraying process.
In the case of HDG, (Hot Dip Galvanizing) taking into account the large number of cylinders manufactured by Faber, would imply a considerable negative impact on the environment. In addition, the temperature at which the HDG is undertaken is quite high (around 450°C) and could affect the final properties of the steel cylinders (it is worth noting that most periodic inspection and test documents limit temperature of steel cylinders to around 350°C during all parts of the retest cycle).

HDG has also been known to cause an embrittlement of the steel material, due to the evolution of hydrogen during the initial pickling stage of the overall HDG process with the hydrogen getting absorbed into the steel.
On a separate note, when it comes to surface finish, our studies have shown that the performance of the top coat is not acceptable when applied on HDG treated cylinders. This is often related to the criticality of surface preparation when a top coat paint is applied.

Thus after careful deliberation of other available coating processes, Faber has decided not to adopt the HDG process and has instead optimized its production cycle involving hot zinc spraying coupled with a primer + top coat of paint, which gives the best trade-off between corrosion resistance and an attractive appearance.

Our clients appreciate and are accustomed to the winning look of Faber cylinders, not to mention the beneficial effects that our approach has towards the environment.

Does anybody know if the Faber hp 3442 tanks have a lower hydro failure rate than the worthingtons or the PST's? I know that some of the worthingtons/PST's can have issues passing hydros and wondering if the high temperature of the hot dip galvanizing process is a contributing factor?

I have both Faber and Worthington tanks, think they're both quality tanks but curious if one or the other has higher rates of hydro failures.

The only PST failures I'm aware of were performed by facilities that did not perform PST's "pre-stretch" Technical Bulletin before the hydro. I'm not aware of any Worthington failures.

I prefer the buoyancy characteristics and size of the Worthingtons vs. Faber. Just personal preference

Yeah, the only reason to opt toward Faber IMO would be tropical warm water diving with it's slightly less weight...
