• does not fall under ASTM B31.3

• has not been tested

• are being fabricated

• have been in-service

All of the following can be an API 510 authorized inspection agency except the inspection organization of:

• The owner/user

• The jurisdiction

• A manufacturer

• An insurance company

What is a defect in pressure vessel?

• An imperfection that exceeds the specified acceptance criteria.

• A response or indication of a flaw noted during the application of non-destructive examination.

• Flaws or others discontinuities discovered during inspection.

• A flaw that may or may not be rejectable, depending upon size.

Who is responsible to the owner/user for determining that the requirements API 510 for inspection, examination and testing are met?

• Repair organization

• Piping engineer

• Operating personnel

• Inspector

Under the requirements of ASME code, Section IX, welding procedures specification used to

• Test the welding machine

• Ensure weldment properties

• Determine the welder's skills

• Determine the welding operator's skills

In ASME section IX, A number is based on

• The weld ability characteristic of a groups of metal alloy

• The chemical composition of the electrode

• The chemical composition of the deposit weld metal

• A group of base metal having specified impact test requirements

Temper embrittlement is defined as:

• An increase in ductility and notch toughness caused by post weld heat treatment (PWHT) or high temperature service above 120 F.

• A decrease in ductility and notch toughness caused by post weld heat treatment (PWHT) or low temperature service below 120 F.

• A decrease in toughness caused by long term exposure in the temperature ranged of 650 F to 1100 F.

• An increase in toughness caused by long term exposure in the temperature ranged of 650 F to 1100 F.

A welder's performance qualification may expire when the welder has not welded particular process for more than:

• 1 month

• 10 weeks

• 3 months

• 6 months

When remaining safe operating life of vessel is 3 years, the internal inspection interval may be a maximum of:

• 1 year

• 1.5 years

• 2 years

• 3 years

A vessel in ethylene product condensate service have been removed and put into steam condensate service. The corrosion rate of the vessel while the ethylene service was 0.001 inch/year. The inspector should:

• Require rerating of the vessel

• Require a pressure test

• Establish a new probable corrosion rate

• Continue to maintain the old corrosion rate
