In-Service Pipeline Inspections
The EPOCH 6LT flaw detector is light and ergonomic, making it a good choice for in-service pipeline inspections. The instrument includes flaw sizing software, such as dynamic DAC/TCG and DGS/AVG for weld and crack sizing inspections, as well as optional corrosion software for efficient and precise pipeline corrosion inspections.
Features for In-Service Pipeline Inspections
The EPOCH 6LT flaw detector features an improved corrosion software option, including:
- Automatic probe recognition and configuration with center pin ID
- Dynamic toggle between flaw scanning and high precision spot measurement modes
- Automatic Gain Control (AGC)
- Thickness gage high precision measurement algorithm
- Automatic zero function (“Do Zero”)
- Grid view for data visualization
The EPOCH 6LT flaw detector features the same high dynamic range pulser/receiver as the EPOCH 650 flaw detector, including:
- PerfectSquare TM tunable square wave pulser
- Digital high dynamic range receiver
- Eight (8) 100% digital filter sets
- Pulser voltage from 100 V to 400 V
- Five customizable digital measurements
Standard Flaw Sizing Software
- Dynamic DAC/TCG: Compares signal amplitude to a DAC curve or reference echo amplitude; the DAC version includes standard, custom DAC warning curves, and 20-80% views
- DGS/AVG: Compares signal amplitude to a DGS/AVG diagram, which illustrates the relationship between echo height, flaw size, and distance from the transducer
