Magnaflux 42-955 Sonotrace 30 Ultrasonic Couplant 55 Gal

Product Description

The MAGNAFLUX 42-955 is a general-purpose ultrasonic couplant supplied in a 55-gallon drum format. Ultrasonic couplant is applied between a transducer and a test surface to eliminate air gaps and allow sound waves to transmit efficiently during ultrasonic testing (UT) inspections. The Sonotrace 30 formulation is designed for broad compatibility across a range of materials and surface conditions, making it a practical choice for NDT technicians performing thickness gauging, flaw detection, and weld inspections in both shop and field environments.

Sonotrace 30 couplant is suited for general industrial NDT applications including structural steel inspection, pipeline work, pressure vessel examination, and weld quality verification. The 55-gallon drum format is intended for high-volume operations such as inspection shops, manufacturing facilities, and service contractors that require a bulk supply to minimize replenishment frequency and reduce per-unit cost. It is applied by hand, brush, or automated dispensing systems depending on the inspection setup.

Key Features

Compatibility

Designed as a general-purpose ultrasonic couplant for use with standard contact ultrasonic transducers across a broad range of ferrous and non-ferrous test materials.

Installation Notes

Ultrasonic couplant is applied by qualified NDT technicians following applicable inspection procedures and standards such as ASTM or ASNT guidelines. Ensure the test surface is clean and free of loose scale or debris before applying couplant. Follow facility and safety data sheet guidelines for handling, storage, and disposal of bulk couplant drums. Do not use couplant on surfaces or at temperatures outside the ranges specified in the product safety data sheet.
