A hard oxide coating will gradually build up on the inside of power generation boiler tubes. Thicker the oxide layer, less efficient is the boiler and the additional heat build-up will shorten the life of the boiler.

Benefits at a view:
measure thinner oxidescale layers
measure oxide on thick wall boiler tubes
save a-scan and instrument parameters in data sets
use compare mode to view set-up standard against actual measurement
high display resolution and range allows for clear signal interpretation and resolving the measurement
our solution:
the object of the test is to perform a separate thickness measurement of the steel tube wall and the oxide scale layer located on the id of the tube.

The interface echo from the tube-to-oxide is much smaller than the echo from the oxide-to-air interface and thus, the difficulty is separating these two echoes from each other and making the measurement between the two echoes

using a highly damped alpha type straight beam shear wave probe is the key to obtain thin oxide layer measurements. The shear waves have half the velocity of l-waves which doubles the time resolution and enables the system to measure thinner layers than with conventional l-wave probes.

One of the major advantages of eddy current as an ndt tool is its variety of inspections and measurements that can be performed. Using our eddy current equipment we can produce high resolution and accurate report by analysing software.

Metus ndt services provides eddy current testing to our customers in different industries with highly sophisticated eddy current equipment.

Our valuable services in eddy current testing are as follow:
tube inspection
material sorting
crack detection
material thickness measurements
coating thickness measurements
conductivity measurements for:
material identification
heat damage detection
case depth determination
benefits at a view:
sensitive to small cracks and other defects
detects surface and near surface defects
very fastest technique
portable equipment.
Minimum part preparation is required
test probe does not need to contact the part
inspects complex shapes and sizes of conductive materials
some of the limitations of eddy current inspection include:
only conductive materials can be inspected
surface must be accessible to the probe.
Reference standards must be maintained.
Depth of penetration is limited for all materials.
Flaws that lie parallel to the probe coil winding and probe scan direction are undetectable.

Benefits at a view:

with pmi testing services from metus ndt services, you can be sure of:
quality control and assurance
knowledgeable data acquisition and analysis
early detection of defective parts, saving you costly field repairs
reduced risk of company liability with documented inspection reports
metus ndt services' exclusive one-stop service
our services for positive material identification:
metus ndt services offers pmi testing services through experienced, trained personnel who can assure quality service. The material scan and testing can be performed on-site before the pieces go into service. It can be utilized on a variety of part sizes from large complex parts to things as small as the weld fill material on the pieces.

In modern applications, equipment failures are usually preceded by an abnormal temperature pattern and this temperature rise can be easily detected by an ir thermographic inspection.

Our solution:
metus ndt services provides full benefits of infrared thermography to our customers in various industrial applications. Our service team is equipped with a highly sophisticated infrared thermal camera. Using this camera together with powerful analysis software, we are able to produce high resolution and accurate predictive maintenance report.

Our inspections are carried out by well experienced asnt certified personnel using best in class equipments available in recent times. We also provide you the complete analysis at an affordable cost.

Benefits:
the advantages of using infrared thermography is that it can reduce unplanned down-time and maintenance costs, which also helping to improve production, equipment life and plant safety.

Where should we do infrared thermography?
inspections of electrical systems such as transmission lines, distribution lines, switchboards, transformers, circuit breakers, electrical panels and cables.

Inspection of mechanical systems such as turbines, paper machines, motors, pumps, fans, heat exchangers, cement kilns, conveyor belts, and bearings.

Inspection of machine structural integrity such as boilers, chimneys, refractories, furnaces, flares, storage tanks, and pipes.
Inspection of sediment and liquid level in vessels and storage tanks.
Inspection of lagging integrity.
Roof moisture analysis
heat lossgain analysis
why is it beneficial for you?
by identifying these electrical anomalies before it develops into a more serious problem, disruption in your production due to failure of these equipment or components are reduced. Mostly undetected electrical anomalies can lead to electrical short circuit which can cause fire.

A technical report will be given on the anomalies found during the survey which details the location of the anomaly, the criticality of the anomaly and the recommended actions to be taken to rectify the anomaly.

A rescan will also be provided to ensure that the rectification works carried out on the anomalies have been executed effectively.

It is the best practice for monitoring rotating equipment (cooling towers, gear boxes, pumps, electric motors, blowers, turbines, etc.). Vibration analysis is also important for acceptance testing for equipment installations (building floors, piping, rotating equipment).

Our services are provided across all sectors of the production and manufacturing industry, such as power generation, mining and mineral processing, oil and gas, petrochemical, automotive, paper & pulp, utilities and food and beverage. Our engineers and technicians are capable of delivering multiple condition monitoring technologies and corrective maintenance techniques. Failure prevention associates can also optimize your machine performance through vibration analysis and its other services.

Benefits at a view:
widely applicable
consistent across all equipment
simple data comparison
early problem detection
strong fault diagnosis (installation, manufacture, component & lubrication etc)
increase plant uptime profits
extend maintenance periods reduce spares stock
improve shutdown scheduling
