The original bid proposal by FPI for the curve sections was to supply 16-foot pipe lengths with a 5-degree single miter bend near one end that would be laid in the bottom of the existing RCP with the FRP miters in the same location as the existing RCP bevels.
The flyer lists capabilities that include untethered, robotic inspection; self contained launcher/receiver connects to any convenient access point or hot tap; MFL, IDOD discrimination, and caliper inspections; wireless communications to and from; streaming video during surveys; live review of ILI data during survey (unverified during live review); normal operation in live gas pipelines and out-of-service liquid pipelines; miter bend passage; branch connection and dead leg inspection; plug valve passage; no flow/low flow operation; on-board power generation (assuming sufficient flow conditions in gas pipelines); and multi-diameter operation (navigation in 18-26 inch pipe with either 20-22 inch inspection or 24-26 inch inspection).
A miter bend consisting of any angle larger than 12[degrees] should be carefully evaluated with the in-line inspection vendor.
The remaining sections of the tool that had not yet entered into the miter bend would remain at a higher velocity.
The tool was being "pushed" through the miter sections by the cups in the recorder section that had not entered into the miter bend.
These design modifications were required because the pipeline included an unknown number of appurtenances such as bell and spigot joints, chill rings, and miter bends, reflecting the construction practices common in the 1940s.
At the time of construction, it was common practice for pipeliners to fabricate miter bends when factory-made forged bends were unavailable.
Additional Enhancements ranging from 3D Graphs to Support for Miter Bends in Piping
The challenges facing "unpiggable" pipelines are often associated with reduced bore valves, miter bends or changes in diameter.
This allows technicians to visually check pipe condition, determine how much cleaning is necessary and locate any obstructions such as miter bends, protruding services or sharp weld slag.

Inspection at the Medford site showed more 45 degree bends than were previously thought to be in the pipe, as well as, some drip pots and miter bends than required removal prior to liner installation.
