PULSATION DAMPERS COMPLYING WITH
THE PRESSURE EQUIPMENT DIRECTIVE

Your choice, ASME code which: Claims to be non-applicable to dampers "snubbers" at a massive cost, and which increases allowable working stresses 3 times a year, arbitrarily neglects fatigue consideration nor requires FEA below 3000 psi/207 Bar, whilst granting certification in all low cost producer countries. Furthermore the ASME, while being an ISO registrar, employ quality auditors who denegrate the international standard. Or, $125 US, certified to the relevant category for your actual use, ID "Suitability For Purpose" backed by criminal law.
