XS Scuba:Hi Peter C:
Yes, you are correct. All Worthington steel cylinders (13 models) manufactured after approximately November 2005 have a Hot Dip Galvanized finish. For approximately the six months prior to that only the LP Series was available (LP85, LP95, LP108 & LP121) these were manufactured with a painted (white) finish. At that time we were still setting up the galvanizing process. If scubafanatic was to check the hydro date of the painted white cylinder he would find a 2005 year manufacture date.
pescador775:XS SCUBA, what are the yield and burst pressures for the Worthington LP cylinders?
TIA
XS Scuba:pescador775:
The yield and burst pressures of the Worthington LP cylinders are exctly what is required by DOT under the classification 3AA for 2400+ (2640psi). Not any less and not anymore. The maximium fill pressure stamped in the shoulder of these cylinders is exactly that, the maximum fill pressure. They are not "overbuilt" to safely be pressurized beyond 2640. If they were I would have steel removed and reduce my cost.
MarcG:So much for tank hydros at 5/3rds of working pressure. :sarcasm:
