Hatfield, PA, December 24, 2008 --(PR.com
)-- Laboratory Testing Inc. (LTI) recently expanded immersion ultrasonic testing (UT) capabilities with the installation of a 24 foot by 5 foot immersion tank. A two-axis, five-channel A, B, and C scan immersion ultrasound system was installed to perform testing of round material up to 20 feet long and 24 inches in diameter and flat material up to 20 feet long and 4 feet wide, with a weight limit of 5000 pounds. The new immersion tank is equipped with a computer-based recording system, which generates detailed printouts of test data and results, an option not available with contact ultrasonic testing.
Laboratory Testing already had extensive capabilities for immersion UT inspection with three high-speed immersion machines for round stock between 1/8 inch and 6 5/8 inches diameter, and lengths up to 75 feet. The contact inspection method was used for ultrasonic testing of material outside these size and shape limitations. The new immersion capabilities provide a speed and reliability advantage over the contact method, as well as chart recording and printouts not available with contact ultrasonic testing.
According to Phil Trach, NDT Technology Coordinator and ASNT NDT Level III, "This new system greatly expands the scope of LTI’s immersion capabilities, provides faster turnaround for large volume, repetitive orders and adds a control factor for higher accuracy that is not available with the contact method of inspection. Our long-term experience with immersion ultrasound and with inspection of large-diameter and very heavy pieces makes this a natural extension of ultrasonic capabilities for Laboratory Testing Inc.”
Ultrasonic Testing (UT) is an inspection method used to find internal and external defects or to measure wall thickness discontinuities in materials and parts. This nondestructive testing process does not damage the material during testing. An ultrasound probe connected to a diagnostic machine passes over the item being inspected and transmits high-frequency sound waves into the item. A defect or inconsistency will cause some of the energy to be reflected. This reflected signal can be processed to give useful information about the condition which caused the reflection. Ultrasonic testing can be performed either by the immersion or contact methods. Immersion inspections take place in a liquid which conducts the beam of sound between the probe and test material. With the contact method, an ultrasonic probe emitting sound waves is run over the surface of the test piece.
About Laboratory Testing Inc. -- Laboratory Testing Inc. of Hatfield, PA has been in business since 1984, and specializes in materials testing, nondestructive testing, dimensional inspection, specimen machining, failure analysis and calibration services. The lab is accredited to ISO/IEC 17025 by PRI/Nadcap and A2LA. Mechanical, chemical, metallurgical and nondestructive testing services are performed on metals, alloys and other materials. Instrumental and wet chemical analyses are offered for additional materials including, powdered metals, ores, ferroalloys, composites, ceramics, aerospace materials and nuclear materials. Test specimens are machined on-site and material investigations are conducted to determine the root cause of material failures. First-article and third-party dimensional inspections are performed on machined products and parts. The calibration lab provides dimensional, pressure, force, torque, mass and vacuum calibration services traceable to NIST. Field calibration service is offered for surface plates, hardness testers, optical comparators, balances, hand tools and testing machines. LTI provides new instruments and replacement parts as a representative for manufacturers such as Mitutoyo, Starrett, Boston Centerless, Glastonbury Southern Gage and Vermont Gage.
