API 570 Process Piping Inspection

API 570 Process Piping Inspection

All hydrocarbon & chemical process piping that has been placed in service falls under API-570. Some piping that has been designated as “out of service” may be covered under this code if it is possible that it would be a safety hazard due to continuing deterioration. Other piping not specifically mentioned in this code can be inspected at the owner user’s discretion, such as PVC and Tubing.
