API 510 Code Compliance & Safety Regulations 3

Question 1

The National Board Inspection Code (NBIC) is primarily used in conjunction with API 510 for which purpose?

Accepted Answer

Governing repairs and alterations to pressure-retaining items

Answer

The NBIC (ANSI/NB-23) provides rules for inspection, repair, and alteration of pressure-retaining items after they leave the original manufacturer.

Question 2

Under API 510, an 'alteration' to a pressure vessel differs from a 'repair' in that an alteration:

Accepted Answer

Changes the vessel from its original design configuration

Answer

An alteration changes the vessel's design intent, pressure rating, or configuration, whereas a repair restores a vessel to a suitable condition without changing design intent.

Question 3

According to API 510, what document must be prepared and retained after completing an alteration to a pressure vessel?

Accepted Answer

An alteration report filed with the National Board

Alterations require an alteration report (typically NB Form R-2 or equivalent) that must be filed with the National Board and retained by the owner.

Question 4

Which API standard specifically addresses Risk-Based Inspection (RBI) methodology for pressure vessels?

Accepted Answer

API 580 and API 581

Answer

API 580 provides RBI principles and API 581 provides the detailed risk-based inspection technology methodology for pressure vessels and piping.

Question 5

In API 510, the term 'corrosion allowance' refers to:

Accepted Answer

Extra material thickness added at fabrication to account for future corrosion

Answer

Corrosion allowance is additional thickness built into the vessel design at fabrication to account for anticipated metal loss during the vessel's service life.
