Answer 2

Imperfections

Question 3

MDMT is the __________. __________ at which a significant pressure load can be applied to piping system as defined in applicable construction code

Answer 3

Lowest temperature

Question 4

Injection points subject to accelerated or localized corrosion may be treated as

Answer 4

Separate inspection circuits

Question 5

Pressure relieving devices should be tested and inspected at

Answer 5

Frequent enough intervals to make sure the PRDs perform reliably in service

Question 6

Barlow formula for t

Answer 6

t= PD/2SE

Question 7

Remaining life formula

Answer 7

t actual - t required / corrosion rate

Question 8

Long term corrosion rate formula

Answer 8

t initial - t actual / years between

Question 9

Short term corrosion rate

Answer 9

t previous - t actual / years in between

Question 10

Answer 10

API publication 2201

Question 11

All repair and alteration welding to piping systems shall be done in accordance with the

Answer 11

Principles of ASME B31.3 or the code to which it was built

Question 12

How often should cathodically protective buried piping be monitored to assure adequate levels of protection

Answer 12

Regularly

Question 13

How often should above grade visual surveillance of a buried pipeline right-of-way be made

Answer 13

Approximately six month intervals

Question 14

How often should poorly coated pipes with inconsistent cathodic protection potentials have a pipe to soil potential survey made

Answer 14

Every five years

Question 15

The leak test for buried piping should be for a period of

Answer 15

Eight hours

Question 16

Barlow formula for MAWP

Answer 16

MAWP= 2SET / D. T is projected thickness

Question 17

Services with the highest potential of resulting in an immediate emergency if it leak were to occur are in class

Answer 17

1

Question 18

Services not included in other classes or in class? This classification includes the majority of unit process piping and selected offsite piping

Answer 18

2

Question 19

Services that are flammable but do not significantly vaporize when they leak and are not located in high activity areas or in class? Services that are potentially harmful to human tissue but are located in remote areas may be included in this class

Answer 19

3

Question 20

Services that are essentially nonflammable and non-toxic or in class? As are most utility services. Inspections of this class of piping is optional and usually based on reliability needs and business impacts as opposed to safety or environmental impact
