scope:

These requirements are for stationary cylinder discharging manifolds for compressed gases for industrial use. Manifolds are used to connect compressed gas cylinders together to supply a distribution system with a particular gas at a selected distribution pressure. The requirements cover manifolds complete to the point where they connect to a distribution system.

Three basic gas groupings are covered:

• Fuel gases (grouped as acetylene, liquefied fuel gases, and nonliquefied fuel gases)-maximum 3000 psi at 70 °F (20 684 kPa at 21.1 °C);1, 2

• Oxygen and air-maximum 3000 psi at 70 °F (20 684 kPa at 21.1 °C); and

• Carbon dioxide, nitrogen, and inert gases-maximum 3000 psi at 70 °F (20 684 kPa at 21.1 °C).

Manifolds for gases used in oxy-fuel gas systems should be installed as outlined in NFPA 51, Standard for the Design and Installation of Oxygen-Fuel Gas Systems for Welding, Cutting, and Allied Processes [2].

This publication does not cover manifolds for medical gas cylinders, for charging cylinders, or liquid withdrawal from portable cryogenic containers (DOT 4L/TC-4LM).

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, Guideline for Metric Practice in the Compressed Gas Industry [1].
