CHAPTER 2

PIPING

This chapter will describe the materials used most often for piping networks and systems
described in this handbook. This chapter includes information on pipes, fittings, valves,
jointing methods, hangers, and supports.

PIPE AND COMPONENT SELECTION
CRITERIA

CODE ACCEPTANCE

Plumbing Systems
When selecting a piping material for any component of plumbing-related systems, the
applicable plumbing code is of primary importance. Here, the allowable piping materials
will be listed as well as any restrictions for their use. In addition, the code will also stipulate
various accepted standards that govern the manufacture, tolerances, and installation of all
components.
When renovating an existing facility or where circumstances require a unique design,
it may be necessary to request a deviation from the accepted list of materials in order to
match existing piping or obtain special design characteristics. The authorities reviewing
such requests require enough information to determine that the intent of the applicable
code provisions is followed in terms of safety and suitability of materials for the purpose
intended.
Applicable plumbing and model building codes are discussed in Chap. 9, “Plumbing
Systems.”

Other Code Requirements

Codes required for systems other than plumbing are generally the following:
1. ANSI B31.l-9 series
2. FDA requirements, such as cGMP
3. Sanitary 3-A Standards for the food and pharmaceutical industries
