eMAG wire rope inspection
eMag wire rope inspection is carried out to:
- ensure safety;
- conform to regulatory requirements;
- extend rope life; and
- settle disputes as to the condition of a rope.
Prior to the introduction of the eMag technique, the condition of ropes had to be assessed by external appearance. eMag enables ropes to be assessed through their entire thickness.
History
The use of eMag testing in Malaysia began with winch ropes at ship lifts. The success of this work in Malaysia is described in a paper presented in the 8th European Conference on NDT in Barcelona in 2002.
Since then, eMag has been extended to the large cranes used in the oil and gas industry. We have tested these cranes onshore and offshore.
Equipment Capability
- We can test ropes in the size range 6-64mm diameter.
- The data logger can hold up to 32,000m of test result in memory
- Maximum rope speed through eMag head is 2m/second
- For breaks on the surface, the detector will find one broken wire in as many as 250 wires.
- For internal breaks, the detector will find fractures when they amount to 1% or more of the total number of wires.
- For corrosion at any location, the detector will find 1% or more loss in cross sectional area.
- We can provide real time results (as the rope passes through the eMag head) by linking the unit to a lap computer.
Personnel
Our eMAG service is managed by our mechanical engineers, Anand Ghnavello and Poon Poh Wong. Both are ASNT Level II in Magnetic Flux Leakage. Our main operator is Hairol Azman Bin Jawahir, ASNT Level II in MT, PT, UT, ET, and MFL (Magnetic Flux Leakage). He has twelve years experience in rope inspection by the MFL method.
We have two additional operators with ASNT Level II in Magnetic Flux Leakage. Two of our personnel are qualified visual inspectors for wire ropes and slings.
