High Temp Dual Linear Corrosion Array

High Temperature Dual Linear Corrosion Array Advantage NDT Supplies

High-Temp Dual-Linear Corrosion Arrays

The High-Temp Dual-Linear Corrosion Array is optimized for corrosion and erosion inspection at elevated temperatures. The transducer and its replaceable delay line is designed to withstand temperatures up to 200°C (392°F). This dual array features 32 transmit and 32 receive elements to provide larger beam coverage than conventional dual-element transducers. The transmit and receive element sets have an included angle to provide a pseudo-focusing effect in the inspected material.

Temperature & Testing Data

This data is calculated with the transducer, delay, and asset all at 150°C (peek data) or 200°C (celazole data). During actual inspections, there will be a temperature gradient from the asset up to the transducer.
