2 API 570

f) hazardous chemicals above threshold limits, as defined by jurisdictional regulations;

g) cryogenic fluids such as: LN2, LH2, LOX, and liquid air;

h) high-pressure gases greater than 150 psig such as: GHe, GH2, GOX, GN2, and HPA.

1.2.2 Optional Piping Systems and Fluid Services

The fluid services and classes of piping systems listed below are optional with regard to the requirements of API 570.

a) Fluid services that are optional include the following:

1) hazardous fluid services below threshold limits, as defined by jurisdictional regulations;

2) water (including fire protection systems), steam, steam-condensate, boiler feed water, and Category D fluid
services, as defined in ASME B31.3.

b) Other classes of piping systems that are optional are those that are exempted from the applicable process piping
construction code.

1.3 Fitness-For-Service and Risk-Based Inspection (RBI)

This inspection code recognizes Fitness-For-Service concepts for evaluating in-service damage of pressure-
containing components. API 579 provides detailed assessment procedures for specific types of damage that are
referenced in this code. This inspection code recognizes RBI concepts for determining inspection intervals. API 580
provides guidelines for conducting a risk-based assessment.
