Tube Inspection Services
BISCO’S Services provides a comprehensive inspection program consisting of multiple tube inspection techniques, to determine the integrity of heat exchanger tube bundles. A variety of state of the art inspection methods such as: Eddy Current Testing (ET) of non-ferrous tubing and Remote Field Inspection (RFT) of ferrous tubing are supplied by MISTRAS Services. A Remote Visual Inspection (RV) is typically employed for follow-up inspection of defective tubing to aid in root cause analysis.
Eddy Current Testing
Eddy Current Testing is the fastest way to assess the condition of non-ferrous tubing in chillers, condensers, feed water heaters and evaporators. With data collection speeds twice that of any other inspection method, work is performed swiftly and efficiently. Our clients are provided with immediate results or the data is stored and reviewed at a remote location. We also perform trending analysis as an option. Results are accurate and require little or no follow-up scrutiny.

  • Condensers
  • Feed water heaters
  • Heat exchangers
  • Air Conditioner

This technique is suitable for the detection and sizing of metal discontinuities such as corrosion, erosion, wear, pitting, baffle cuts, wall losses, and cracks in nonferrous materials.

IRIS Tubular Inspection
BISCO utilize the most advanced IRIS technologies for heat exchanger tubular inspection. BISCO currently use the Olympus NDTMS 5800 ER1U, instruments for our tube testing instruments.

This instrument has the capabilities of presenting a “Real-Time C-Scan of the IRIS data as it is being inspected. This is a great aid in helping the Technician or Operator to visually pin point flawed areas in the tube on the fly. All of the IRIS data is stored for post analysis of the data and archived for future needs.
We are doing inspection in the following auxiliaries,

  • Boilers
  • Feed water heaters
  • Air coolers
  • Heat exchangers
Remote Field Testing (RFT)
BISCO using MS5800 equipment for tube inspection Remote field testing & Magnetic Flux Leakage.
We are doing inspection in the following auxiliaries,

  • Boilers
  • Feed water heaters
  • Air coolers
  • Carbon steel heat exchangers
Magnetic Flux Leakage Testing (MFL)
Magnetic flux leakage (MFL) is a fast inspection technique, suitable for wall-loss measurement and detection of sharp defects, such as pitting, grooving, and circumferential cracks. MFL is effective for aluminum-finned carbon steel tubes, because the magnetic field is mostly unaffected by the presence of such fins.

Advanced UT
Phased Array Inspection

BISCO has Omni scan with phased array module for inspecting the cross country pipelines. This is the instrument from Olympus NDT, Canada. This Omni scan was well supported by Tom view software for offline analysis.

Time-of-Flight Diffraction (TFOD)

BISCO uses Omniscan from Olympus, Canada to carry out this effective technique. Omni Scan UT allows inspections simultaneously combining TOFD with conventional pulse echo. Pulse echo complements TOFD and covers the dead zones.

Pipe line Automated UT (AUT)

BISCO have weldstar equipments of GE inspection technologies which is a most advanced automated ultrasonic girth weld inspection system using phased array technology for cross country oil & gas transmission pipeline projects. Pipes are girth-welded on site, typically using automated welding. Then, they are rapidly inspected, coated, and buried. Due to the demanding construction cycle, it is important that any defect in the welds be detected and analyzed very quickly.

Omni Scan 2-channel UT B-Scan for Corrosion Mapping

BISCO, a leader in nondestructive testing technologies, is providing the Omni Scan® channel Ultrasound B-Scan for Corrosion Mapping -the newest Omni Scan-based NDT solution from Olympus NDT, Canada. This kit includes the OmniScan MX UT instrument, the manual Remote Scan B-scan position encoder, TomoView Lite software, and a dual-UT.

Positive material identification (PMI)

A state of the art portable X-ray Fluorescence Spectrometer which uses an X-ray tube Instead of a radioactive source, and provides much quicker analysis times.
BISCO utilize this type of equipment in the petro chemical and power industries, however it could be used in all applications where a client may need to find what material is being bought as crosscheck to the mill certificates.

Long Range Ultrasonic Testing (LRUT)

Long range ultrasonic testing is a rapid way of screening for corrosion in pipelines. The method enables screening of up to 100 meters of pipeline in one test, i.e. 50 meters in both directions.
By fitting a ring of transducers around the pipeline, a wave maker device directs low frequency (20-100 kHz) ultrasonic waves via the transducers, longitudinally into the pipeline wall. The method effectively detects changes in the pipeline’s cross-section, enabling it to identify corrosion and other abnormalities. At the same time this provides the possibility of using welds and flanges as distance references.

Pipe inspection using MFL

BISCO has silverwing’s pipe scan equipment for magnetic flux leakage testing on pipes. The latest magnetic material coupled with unique mechanical designs enables coverage of all pipe diameters from 50mm to 2.4 meters with a limited number of scanning heads. Magnetic flux leakage inspection is not affected by product flowing through the pipe so surveys can be carried out both on-line and off-line and at surface temperatures up to 90°C.

Boroscopic Inspection

Bisco Offers Boroscopy to visually inspect hard reach zones to find surface defects, general condition, degradation, blockages & foreign materials in Electrical generators & transformers , Boilers, pressure vessels, pipelines ,Gas , stem & wind turbines , condenser tubes , drums , pumps, heat exchangers & various plant components without teardown. They can be used to check pitting, cracks, corrosions, erosions, weld defects & other problems quickly & easily.
