Visual Testing (VT)

Visual Examination is a method of NDT that has been neglected for much of its industrial application life. VT was the first NDT method used in the industry, but was last method to be formally acknowledged

It is generally used to determine such things as the surface condition of the part, reinforcement and undercutting of welds, alignment of mating surfaces, shape or evidence of leaking. CIS employ both direct and remote visual aids to carry out VT. CIS has visual Inspectors certified to various codes such as AWS, API, ANSI, ASME, and ASNT.

Leak Testing

Leak testing is performed using gas and bubble formation testing, vacuum testing, the halogen diode detector, the helium mass spectrometer reverse probe the helium mass spectrometer hood methods and the pressure difference test.

Coatings & Linings

CIS has experienced Painting Inspectors that can make recommendations and develop techniques for the correct application of exterior coatings and interior linings for your equipment. With great experience on painting and lining systems CIS Inspectors can help conduct audits, make recommendations on qualified vendors and supervise projects.

Ultrasonic Testing

The ultrasonic method provides indications of surface and subsurface discontinuities, with the potential to determine the depth and exact size by the use of beams of mechanical waves (vibrations) of short wavelength and high frequency, transmitted from a small probe in contact with the specimen surface and detected by the same or other probes. These Ultrasonic pulses could indicate the presence, absence, and location of flaws, interface and/or discontinuities.

Ultrasonic examination for thickness determination may be made using either the resonance or pulse-echo technique. This technique determines thickness or reveals corrosion discontinuities near the surface or deep within components or structures. Applications include location of manufacturing defects in welds and castings through to Corrosion / Erosion monitoring and large scale corrosion mapping.

Positive Material Identification

Positive Material Identification (PMI) is a process used to determine the chemical composition of materials. The test identifies the alloys that make up a particular material.  The purpose of this NDT method is to ensure that only materials that are specified as part of the design requirements are supplied and used for production.

Magnetic Flux Leakage

This is part of the reliability service offers by Climax Inspection Services. The Company have noted that Magnetic Flux Leakage (MFL) is one of the best suited techniques for early detection of damage in the fin fan tubes and storage tank inspection. This method can detect corrosion at an early stage when the pit depth is only 21% of the tube wall, regardless of heavy deposits in the tubes. As for tube end grooving, even if it is located as close to a half-inch from the tube end, there is no better and faster technique. The aluminium fins don’t pose any problem as they are non-magnetic and don’t influence an MFL reading.

Radiographic Testing (RT)

Radiographic Testing is a well established NDT method which uses Gamma or X rays to produce the image of a material onto film. Radiography provides a quality, cost effective, permanent record with high volume capabilities due to simple operation and portability. Applications include wall loss detection (profile radiography) and sizing in pipes and plate through to manufacturing defects in welds, forgings castings etc

However, the major demerit is the inherent risks associated with the use of radioactive isotopes and the need to establish and manage a controlled area during the process. Commonly used radioactive isotopes include Iridium 192, Cobalt 60 and Selenium 75.

Magnetic Particle Testing (MT)

The Magnetic Testing method can be used on ferromagnetic materials to reveal surface discontinuities and, to a limited degree, those located below the surface. It is an extremely cost effective method used primarily for the detection of cracks. Following magnetisation the specimen is covered with very fine iron particles either dry or suspended in a liquid. Surface breaking flaws distort the magnetic field causing local magnetic flux leakage that attracts the iron particles producing a build-up that can be seen visually.

 

Eddy Current Testing (ET)

Eddy Current theory is based on the principles of electromagnetism. A coil carrying an AC current is placed on the magnetic test object. This generates circulating eddy currents in the test material close to the surface and these in turn affect the current in the coil by mutual induction. Flaws and material variations affect the strength of the eddy currents. The presence of flaws is therefore measured by electrical changes in the excitation coil. ET applications range from crack detection to metal sorting and weld inspection.

Penetrant Testing (PT)

The basic principle upon which Penetrant Testing is based is that of capillary attraction. This is a surface tension phenomenon that permits liquids to be drawn into tight openings as a result of the energies that are present at the surface of the openings. PT method is used to detect surface discontinuities only. The major advantage is that this method can be used on both ferrous and nonferrous materials. The application include the detection of surface discontinuities such as cracks, seams, laps, cold shuts, laminations and porosity. The indication can be viewed with visible daylight or using fluorescent method.

Vendor Audits

The purpose of these audits (prior to Purchase Order award), is to verify that vendors and their sub-vendors appear to be capable of fulfilling the requirements of the purchase order.

The scope of services may include assessing the Purchase Order requirements, create audit plan, arrange audit visit and stipulate requirements, assessing vendors control procedures and QA system according to ISO 9001:2008

Scope may also include establishing that sub-vendors have been assessed under vendors QA procedures, carrying out thorough review of vendors expediting and corrective action procedures, assessing Vendor Plant / Manpower / Operational capacity to satisfy customers PO requirements and providing audit reports.

Expediting

CIS can help Customers carry out Expediting to ensure that the Vendor or Suppliers delivers on time and in accordance with the relevant standards and specifications set out in the scope of work. The scope of services may include

Monitoring and reporting conformance to relevant standards, codes, specifications and specific Supply Chain Management requirements, Identifying / resolving bottlenecks at all levels

Evaluating progress to date and assist the Supplier or Sub-Supplier to meet required delivery dates. The CIS Expediter, depending on the contract scope, may also report on the Engineering / Drawing status, Materials and Accessory status, Production / Fabrication status and Shipping status.

New Built Equipment Inspection

CIS Inspectors are trained to carry out impartial inspections of equipment to ensure conformance to client’s standards, codes, specifications and specific scope of work requirements as stated within the PO. New Build Equipment Inspection ensures full compliance of all high value plant and equipment including pumps, pipes, vessels and valves. This ensures that each stage of the client’s purchase order requirements are fully satisfied before the material or equipment leaves the suppliers premises, therefore resulting in minimum potential for production outages and the subsequent threat to safety and asset integrity.

Inspection is usually carried out during all stages of manufacture, FAT, shipping and receipt. The Inspection is based on a risk ranking process regarding type and content. Ranking looks at the consequence and probability of failure. These Inspection services compliment the Expediting process.

Mill Inspection and Surveillance

This service is carried out by specialized CIS Inspectors with in-depth knowledge of forming, welding, NDT, threading, coatings and loading.  Either full or ad-hoc support services are used to compliment the expediting process covering all stages of manufacture and testing which includes traceability, dimensional checks, mechanical testing, threading, pressure testing, storage and preservation.

Tubular Inspection Services

We also undertake the Inspection of both new and used Oil Country Tubular Goods (OCTG).

Relevant tests and inspection of both used and new tubular goods as well as proper storage and inventory are requirements for ensuring optimum conditions and save time and cost for all industrial operations. We manage all tubular materials in our care in accordance with API and other International Specifications and conduct necessary tests including Ultrasonic, Eddy Current Tests and Magnetic Particle Inspection to assure their integrity.

Pressure Testing

At CIS, we also offer pressure testing services. Pressure testing is the final test stage prior to the commissioning or reinstatement of a system. Individual skids, complete modular system, valves, spools, or pipeline can be pressure tested. This final proof testing is normally performed above the design pressure of the system, and various test mediums are employed including liquid and gas.

Heat Treatment

During production welding, heat treatment may be required to relief stress with the overall aim of removing residual stresses that may have been generated during welding. Stress relieving generally aids in the removal of or reduction of the risk of brittle fracture after welding as well as stress corrosion, among other metallurgical problems associated with welding. These thermal treatments therefore assist in assuring weld quality, performance and integrity. CIS has experience personnel and Heat Treatment Machines to serve this purpose.

Statutory Inspection of Facilities (Tanks and Vessels)

In accordance with American Bureau of Shipping (ABS) requirements for survey of different vessel types, ultrasonic gauging is used to confirm integrity of these vessels and to ensure compliance with their annual statutory surveys, intermediate or special periodical surveys as may be required. Most vessels including Tankers, Bulk Carriers, Chemical Carriers, Oil Carriers, Barges, etc are usually subjected to these surveys which cover various sections including deck, hull, transverse sections, cargo areas, ballast tanks, boilers, etc.

Thickness measurements are carried out on these vessels using qualified personnel and calibrated gauges and when extensive areas of wastage are found which exceed allowable margin, renewals are recommended and carried out to an ABS Surveyor’s acceptance
