3-12.3 Pipe Hangers and Supports
The design of pipe hangers and supports shall be based on the Power Piping Code, ASME B31.1.
This Code requires that the materials, design and manufacture of standard pipe supports shall
be in accordance with the rules of MSS-SP-58; the companion document MSS-SP-69 provides
recommendations for the selection and application of pipe support types. This MSS Standard
Practice is published by the Manufacturers Standardization Society of the Valve and Fittings
Industry, Inc., located at 127 Park Street, NE, Vienna, Virginia 22180; phone [phone].
The Piping Design Handbook For Use With Special Hazard Fire Suppression Systems, published
by the Fire Suppression Systems Association (FSSA), provides general information and
guidelines for the selection and application of pipe supports.
3-12.4 Cylinder Manifolds
The carbon dioxide cylinder bank is connected to the discharge pipe network through a
manifold. The manifold consists of an arrangement of pipe and fittings, called a header, which
collects the discharge from each cylinder into a single pipe. One or more headers are connected
to a single outlet connection, called a riser.
3-12.4.1 MANIFOLD ARRANGEMENTS
The manifold may be arranged as an End, Center, or H manifold, with additional design
considerations for connected Main and Reserve systems. The figures shown are exemplary only
and do not represent the only possible configurations. It is permissible to include elbows in the
manifold.
3-12.4.1.1 End
An "End" manifold consists of a single header. Any number of cylinders may be connected.
Figure 3-6. Example of an "End" Manifold
3-12.4.1.2 Center
A "Center" manifold consists of two identical headers connected to a single riser. The total
quantity of cylinders shall be a multiple of 2.
