IFFCO RECEIVES MAD 4D EDDY CURRENT SYSTEM
Indian Farmers Fertiliser Cooperative Limited, AONLA Unit, Bareilly, India, chose the ect MAD 4D eddy current system for inspection of heat exchangers within their plant. IFFCO ordered the XS computer version with four frequency channels, built-in optical disk drive for data storage, ect Data Analysis Software, and ect Report Writing Software. They ordered their system configured for inspecting both ferrous and nonferrous tubes. The system was received at the plant in late September, 1996 with ect's Agent, Batliboi, visiting the plant for commissioning in October, 1996. IFFCO personnel will visit the Eddy Current Technology Incorporated factory in Virginia Beach, Virginia, USA, for training in the near future.
RCF COMPLETES FIRST MAJOR INSPECTION
Rashtriya Chemicals and Fertilisers Limited, THAL Unit, THAL (near Bombay, India) evaluated the various eddy current inspection equipment available on the market for an extended period of time before choosing the ect MAD 4D eddy current system. The system ordered was in a laptop model computer, complete with built- in optical disk drive for data storage and included data analysis software. The system was configured to inspect both ferrous and nonferrous tubes. In February, 1996, Mr. Ramesh Arghode visited the Eddy Current Technology Incorporated factory in Virginia Beach, Virginia, USA for training on the system and used the system for inspecting heat exchangers during a plant shutdown in April. Mr. A. B. Tipnis: "We are happy to inform you that we have successfully used the ect MAD 4D eddy current system supplied by you for testing our stripper and carbamate condenser tubes in our Eurea plants during our recent shutdown."
WORLD NDT CONFERENCE
The 14th World Conference on Non-Destructive Testing will be held at the Taj Palace Hotel in New Delhi, India, from December 8 to 13, 1996. This is an excellent opportunity to view all types of non-destructive testing equipment, and specifically an opportunity to see first hand the advanced features of and high speed operation of the ect MAD 4D eddy current system. To view the ect MAD 4D eddy current system, be sure to drop by the Batliboi, Ltd. booth, number 60 in the Dunbar Room (booth number subject to change).
TELEPHONE NUMBER CHANGE
The area code for all Eddy Current Technology Incorporated's telephone lines is changing. Please note the new phone number of (757) 490-1814 and the new fax number of (757) 490-2778, effective immediately.
ect MAD 4D RELEASE 3.50
Version 3.50 of the ect MAD 4D software in all option configurations is now available. The many new improvements include extensive on line help, as well as phase and gain controls which can be used during playback in order to correct minor errors that occur during data acquisition.
For price and availability information, contact the factory.
MAD 4D SOFTWARE NOW READS INDUSTRY STANDARD TAPES
ect MAD 4D software has been used for years for the computer aided and completely automatic analysis of the eddy current data resulting from heat exchanger tubing inspections. In the past, it was not possible to read and analyze the data that had been stored on tape by competing equipment. Reading industry standard tapes is now possible by using a utility program that reads the data from tape, leaving it in ect *.ECD format, readable by all ect MAD 4D software. For price and availability, contact the factory.
INSPECTING FERROMAGNETIC TUBES
Remote field technology has been around for years for the inspection of carbon steel and other ferromagnetic tubes, and so has the system's limitations. 1. The sensitivity is very low close to support plates.
2. Defects spaced closer than approximately three tube diameters result in the signals from the two defects interfering with each other.
Recently introduced near field eddy current technology solves both of these problems, providing substantially improved defect sensitivity close to support plates and substantially less interference from defects that are close to each other. However, the overall sensitivity of the testing is somewhat less with near field technology.
