Abstract

This publication provides a minimum standard for flexible stainless steel braided hoses with the following inner cores: • ethylene tetrafluoroethylene (ETFE); • polytetrafluoroethylene (PTFE); and • corrugated metal. These hoses have a nominal inside diameter (ID) of 0.25 in (6.4 mm) or less and shall have a maximum allowable working pressure (MAWP) of at least 3000 psi (20 680 kPa) at 70 °F (21.1 °C).1,2 These flexible hoses are sometimes referred to as pigtails. This standard does not cover requirements for other polymeric or elastomeric inner core hoses. 1 kPa shall indicate gauge pressure unless otherwise noted as (kPa, abs) for absolute pressure and (kPa, differential) for differential pressure. Also, kPa values are rounded off per CGA P-11, Guideline for Metric Practice in the Compressed Gas Industry [1]. 2 References are shown by bracketed numbers and are listed in order of appearance in the reference section.
