ISA77.70, Fossil Fuel Power Plant Instrument Piping Installation

Scope

This committee covers the mechanical design, engineering, fabrication, installation, testing, and protection of fossil power plant instrumentation sensing and control lines. The boundaries of their standard span the process tap root valve to the instrument connection. Their standard applies to all fluid media (liquid, gas, or vapor).

Purpose

This committee established the applicable installation requirements and limits of instrumentation sensing and control lines and their instruments in fossil power plants.

This committee addresses the requirements of maintaining the pressure boundary integrity of the instrumentation sensing line (in accordance with the appropriate parts of American National Standards Institute [ANSI] standards).
