TVC Tracking for New Construction Projects
A Path Forward
MERCER TECHNICAL SERVICES
Historical Perspective• 1935, The "American Tentative Standard Code for Pressure Piping”, ASA
B31.1 was issued
• 1955, Section 8, designated B31.1.8, represented a significant technical advancement in requirements for natural gas transmission and distribution piping systems
• 1970, DOT issues original versions of 49 CFR Parts 191 & 192
• 2011, PHMSA issues Advisory Bulletin requiring material to be “Traceable, Verifiable and Complete”
• 2016, PHMSA NPRM: Safety of Gas Transmission & Gathering Pipelines

Steel Pipe (proposed rule)
§ 192.67 Records: Materials.Each operator of transmission pipelines must acquire and retain for the life of the pipeline the original steel pipe manufacturing records that document tests, inspections, and attributes required by the manufacturing specification in effect at the time the pipe was manufactured, including, but not limited to, yield strength, ultimate tensile strength, and chemical composition of materials for pipe in accordance with § 192.55.
MERCER TECHNICAL SERVICES
Pipeline Components (proposed rule)
§ 192.205 Records: Pipeline components.Each operator of transmission pipelines must acquire and retain records documenting the manufacturing standard and pressure rating to which each valve was manufactured and tested in accordance with this subpart. Flanges, fittings, branch connections, extruded outlets, anchor forgings, and other components with material yield strength grades of 42,000 psi or greater must have records documenting the manufacturing specification in effect at the time of manufacture, including, but not limited to, yield strength, ultimate tensile strength, and chemical composition of materials.
MERCER TECHNICAL SERVICES
Welders (proposed rule)
§ 192.227 Qualification of welders.* * * * *(c) Records for transmission pipelines demonstrating each individual welder qualification in accordance with this section must be retained for the life of the pipeline.

Material Tracking Systems
• Tagging system have been in the pipeline industry since 19XX• Various types of tags can be used• RFD• Bar Codes• Wide range of quality• One tag does not fit all needs
• Material Database• What is tracked in the database• Is the database real time
MERCER TECHNICAL SERVICES
Lessons Learned - Tags
• Tags places on the inside of pipe• Comes off the pipe and flows with the product
• Tags prevents pipe coating from being jeeped• Tags destroyed during handling• Pipe is cut at the firing line and pup moved ahead• Tags deteriorated on pipe being stored due to UVThe type and style of the tags you use on your
project is a critical desicion point
MERCER TECHNICAL SERVICES
Material Database Requirements• What data will be stored and the method of storage• Remote access to the database• Office• Field• Operator
• Database security• Levels of access to database• Cyber security
• Storage requirements• Data transfer to operator at end of project
MERCER TECHNICAL SERVICES
Database
Material database can evolve into a project database• Tracking of X-Rays• Welder Qualifications• Hydrostatic test• Maintenance tickets for defective material• Tracking location of material• Inventory control
MERCER TECHNICAL SERVICES
Mapping
• You must be able to tie your material information to the physical location of the material• Fencing will not be excepted• Survey must be integrated with the database• Survey accuracy will be key• Mapping material on a liner pipeline is no problem• Mapping material for fabrication is challenging
MERCER TECHNICAL SERVICES
Planning
• As with any project, planning is key in implementing a material tracking system• Review the process with all stake holders• The material tracking starts with the ordering of the
material to the final as-built into the operators records system• Work with the affected service providers • Combined traditional tasks with new tasks needed
for material tracking
MERCER TECHNICAL SERVICES
Value Added
• Transparency for the project team• Streamline communications through real time
reporting (dashboards)• Reduce the time from physical completion of
project to completion of the project
