I'm pretty sure that the only special consideration for a pressure tank that's different from other tanks is the air supply, which requires a quarterly inspection. Otherwise, latest edition of NFPA 25 requires every three years' internal for all tanks without corrosion protection and 5 years for tanks with internal corrosion protection. I would say a pressure tank bladder is a material that resists corrosion, so 5 years IMHO.
