Standard for Stationary Compressed Gas Cylinder Discharging Manifolds for Working Pressures up to 3000 psig
standard by Compressed Gas Association, 09/01/2015

Description

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 (20 684 kPa) at 70 °F (21.1 °C);
Oxygen and air – maximum 3000 psi (20 684 kPa) at 70 °F (21.1 °C); and
Carbon dioxide, nitrogen, and inert gases – maximum 3000 psi (20 684 kPa) at 70 °F (21.1 °C).

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