API 574- Inspection Practice for Piping System components

Ref : API_574

Process piping system is one of the critical production assets in process industry. Organizations recognize the need to maintain authorized inspection agency and technically assess qualified piping engineers and inspectors to ensure facilities are at top performance. This two-day course is designed for petroleum industry personnel, suppliers, or subcontractors responsible for the design, inspection, maintenance, regulatory compliance, or operation of API Inspection of Piping system.

Learning Objectives

This recommended practice (RP) supplements API 570 by providing piping inspectors with information that can improve skill and increase basic knowledge of inspection practices. This RP describes inspection practices for piping, tubing, valves (other than control valves), and fittings used in petroleum refineries and chemical plants. Common piping components, valve types, pipe joining methods, inspection planning processes, inspection intervals and techniques, and types of records are described to aid the inspectors in fulfilling their role implementing API 570. This publication does not cover inspection of specialty items, including instrumentation, furnace tubular, and control valves.
