ASME ASME Piping Systems B31 Codes 2

Question 1

Which pressure testing method is preferred by ASME B31.3 for process piping?

Accepted Answer

Hydrostatic testing

Answer

Hydrostatic testing is the preferred pressure test method in ASME B31.3 because it is safer than pneumatic testing.

Question 2

In ASME piping codes, what does the term 'design pressure' represent?

Accepted Answer

The most severe coincident pressure and temperature expected during normal operation

Answer

Design pressure is the most severe coincident pressure and temperature condition expected during normal operation, used to determine component thickness.

Question 3

What is the allowable test pressure for a hydrostatic test under ASME B31.3?

Accepted Answer

1.5 times the design pressure

Answer

ASME B31.3 requires hydrostatic test pressure to be at least 1.5 times the design pressure.

Question 4

Under ASME B31.3, a 'normal fluid service' piping system requires what minimum level of radiographic examination for butt welds?

Accepted Answer

Random (10%) radiography

Answer

Normal fluid service under B31.3 requires random radiographic examination of at least 10% of circumferential butt welds.

Question 5

Which ASME B31 code applies to gas distribution piping within buildings?

Accepted Answer

B31.2

Answer

ASME B31.2 covers fuel gas piping systems within buildings and on building exteriors.
