scope:

This publication is a hose management document for noncryogenic compressed gas transfer hoses for maximum allowable working pressures (MAWP) from 500 psig to 3000 psig (3450 kPa to 20 680 kPa), with hose internal diameter ranging from 0.25 in to 4 in (6.4 mm to 102 mm).^{1, 2} This publication provides industry wide procedures for the inspection and testing of compressed gas transfer hose. It is a guide for transfer hose users when they establish inspection procedures. It contains acceptance criteria appropriate for use during product transfers and routine maintenance. It represents the best currently available industry practice, but does not cover every possible hose design, installation, and lading. Each user can apply this publication to suit individual installation and conditions of service. Acceptance for continued service in accordance with this publication does not guarantee that a hose or coupling assembly is not dangerous or cannot fail.

This publication does not apply to vacuum-insulated hoses.

¹ kPa shall indicate gauge pressure unless otherwise noted as (kPa, abs) for absolute pressure or (kPa, differential) for differential pressure. All kPa values are rounded off per CGA P-11, Metric Practice Guide for the Compressed Gas Industry [1].
