ASME B31Q UPDATE
Michael GruenbergWRGC August 2013
Points to Cover
• Committee Structure• Industry Representation• What has been accomplished
Committee Structure
• Chair - Amy Livingston, Compliance Manager Kinder Morgan
• Vice Chair – Mike Burkhart, Program Manager Nicor Gas
• Secretary – Paul Stumpf, ASME
Committee Makeup
• 30 Voting Members• Representing:– Transmission pipeline companies (10)– Distribution companies (8)– Liquid pipeline companies (2)– State and Federal agencies (3)– Vendors (6)– ASME (1)
Member Locations
Committee Work 2012 - 2013
• Preparation for next release• Ad-hoc meetings• Committee meetings• Balloting Process
Preparation for Release
• Revise Task Guidance:– Several instances where the written guidance did
not match the intent of the task.
• Revise Task Language:– Each task rewritten to eliminate by inclusion the
main AOC’s that could be encountered (PHMSA)
– Additional language inserted to add clarity
Examples
Current• Identify requirements• Perform task equipment check• Test/troubleshoot rectifier• Repair or replace defective
rectifier components• Place in service• Adjust output• Recognize and react to AOC’s• If required, complete
documentation
New• Select task procedure(s)
and appropriate equipment• Perform test equipment
check to verify that equipment functions within specified parameters – Inspect equipment– Verify equipment is calibrated– Test equipment
ContinuedTest rectifier and troubleshoot problems•Monitor requirements of all impressed current sources•Visually inspect components of the rectifier•Check electrical connections (anode, ground beds, power supply, structure, electrical ground, etc.)•Identify and locate correct test points•Connect instruments and test leads to correct locations•Operate test equipment and take readings
– Rectifier voltage and current output to include current drains, shunt using a high impedance voltmeter, ammeter (direct or indirect), and shunt, if applicable
– Watt-hour reading, if applicable– Internally mounted voltage and amperage meter
•Analyze and interpret test results– Maximum rated outputs
•Common component failures and output indications
ContinuedRepair or replace defective rectifier components as applicable•AC/DC circuit breakers•Power connection/safety ground•Fuses•Diodes•Disconnects•Rectifying elements•Transformer•Lightening arrestors•Shunts•AC Filters/Chokes•Stack•Meters
Meetings
• Committee Meetings– Three were devoted to the revision
• Ad-Hoc Meetings– Six or more WebEx meetings held
Results
• 109 Tasks have been approved by the standards committee
• 13 have been sent out for a recirculation vote• 20 still being worked• 1 being recirculated in the committee• 2 not yet drafted• 2 tasks were voted on to be removed• 20 diving tasks
What is left
• 20 Diving tasks• 2 Pump or compressor type tasks• 2 Squeeze tasks
Path Forward
• Compete the task revision process• Submit all to standards committee• Publish next version ??? • Pick up the items to be completed that were
tabled for the revision
