Universal Inspection Co. Ltd.

Third-party certification means that an independent organization has reviewed the manufacturing process of a product and has independently determined that the final product complies with specific standards for safety, quality or performance. This review typically includes comprehensive formulation/material reviews, testing and facility inspections. Most certified products bear the certifier’s mark on their packaging to help consumers and other buyers make educated purchasing decisions.

Industrial Third Party Inspection refers to independent inspection services that are provided by inspection agencies. In purchasing and procurement projects the sellers and vendors are first parties. The second parties are purchasers or buyers. First-party inspection refers to quality control activities that are done by equipment vendors or sellers. Second-party inspection refers to inspection activities that are done by equipment buyers or purchasers. The first party is the seller and the second party is the buyer. So when you say second-party inspection, it means that an inspection and quality control activities are done by a buyer and when you say first-party inspection, it means that an inspection and quality check are done by a vendor in its construction shop.

UIC TPI inspector will do for you.

• Assure the quality of the material application
• Provide unbiased reports and a third-party paint inspection
• Report all defects to the consultant and owner at the prep stage, intermediate coat and final finish
• Notify the consultant and owner of any anomalies or irregularities in the specifications
• Review all areas in the scope of work with the paint contractor before prep and paint application
• Unannounced onsite inspections
• Typed reports on defects to consultant and/or owner

TUBE INSPECTION (ECT/RFET/IRIS)

Heat exchangers used for petrochemical or power generation applications may have many thousands of tubes, each up to 20 m long. UIC Services provides a comprehensive inspection program consisting of multiple tube inspection techniques, to determine the integrity of heat exchanger tube bundles. Our extensive experience in heat exchanger inspection assures that components are properly evaluated to detect damage or defects thereby ensuring that tube bundles are safe to remain in operation. Failures can result in unplanned shutdowns, dangerous catastrophic failures or severe costly damage.

A variety of state-of-the-art inspection methods such as Eddy Current Testing (ECT) of non-ferrous tubing and Remote Field Inspection (RFET) of ferrous tubing are supplied by UIC. A Remote Visual Inspection (RV) is typically employed for follow-up inspection of defective tubing to aid in root cause analysis.

Ultrasonic Testing (UT)

It is one of the most common non-destructive testing (NDT) methods where sound waves of high frequency(ranges from 1 MHZ TO 50 MHZ) waves are transmitted into the material being tested and are used to detect surface and sub-surface flaws. The sound waves travel through the materials with some attenuation of energy and are reflected at interfaces. The reflected beam is characterized to define the presence and location of flaws.

Ultrasonic waves are almost completely reflected at metal gas interfaces. Partial reflection occurs at metal liquid or metal solid interfaces, with the specific percentage of reflected energy depending mainly on the ratios of certain properties of the matter on opposite sides of the interface.

Cracks, laminations, shrinkage, cavities, bursts, flakes, pores, bonding faults and other discontinuities that can act as metal-gas interfaces can be easily detected. Inclusions and other inhomogeneities in the metal being inspected can also detected by causing partial reflection or scattering of the ultrasonic waves, or by producing some other detectable effect on the ultrasonic waves.

Most of the ultrasonic inspection instruments detect flaws by monitoring one or more of the following:

1. Reflection of energy from metal-gas interfaces, metal-liquid interfaces or discontinuities within the metal itself
2. Time of transit of a sound wave through the test piece from the entrance point at the sending (transmitting) transducer to the exit point at the receiving transducer, and
3. Attenuation of the beam of sound waves by absorption and scattering within the test piece.

Application

Ultrasonic testing (UT) is used for quality control and materials testing in all major industries (power, oil and gas, foundry etc.). This includes Ultrasonic testing of castings, forgings, plates, extruded components, weld joints, production of steel, aluminium and titanium, and fabrication of structures such as airframes, pressure vessels, ships, bridges, motor vehicles, machinery and jet engines. In-service ultrasonic testing for preventive maintenance is used for detecting the impending failure of pipelines, vessels, and tanks. The flaws to be detected include voids, cracks, inclusions, pipe, laminations, bursts and flakes. They may be inherent in the raw materials, may result from fabrication and heat treatment, or may occur in service from fatigue, corrosion or other causes. Ultrasonic testing can also be used to measure the thickness of metal sections during manufacturing and maintenance inspections.

Advantages

1. It is sensitive to both surface and subsurface discontinuities.
2. It is highly accurate in determining reflector position and estimating size and shape mainly the TOFD (time of flight diffraction) method used for accurate sizing in mm.
3. Detailed images can be produced with automated systems
4. It can replace the requirement of Radiography as per some codes (like ASME code case 2235).
5. Instant results due to electronic equipment.
6. Can be highly automated or portable.

Limitations

1. Ultrasonic Flaw detection requires experienced inspectors.
2. Extensive technical knowledge is required for the development of Ultrasonic testing procedures.
3. Rough parts, irregular in shape, very small or thin or not homogenous are difficult to test
4. Discontinuities that are preset in a shallow layer immediately beneath the surface may not be detectable.
5. Couplants are needed to provide effective transfer of ultrasonic wave energy between transducers and parts being tested.
6. Reference standards are needed, both for calibrating the equipment and for characterizing flaws.
7. Cast iron and other coarse-grained materials are difficult to inspect due to low sound transmission and high signal noise.
8. Linear defects oriented parallel to the sound beam may go undetected.
