Field NDT

Non-Destructive Evaluation methods are available on a call-out basis or for long-term projects. When employed at critical stages of the construction, manufacturing or fabrication process, Stork Cooperheat's NDT (Non Destructive Testing) field services work to optimize production and assure the quality of your finished product.

Visual Inspection

Visual Inspection is one of the most cost-effective methods to assess ongoing equipment reliability and typically is one of the first methods of NDT. In addition, visual inspection serves as a quality control and quality assurance function during the fabrication of new equipment. Employing a multi-national skilled workforce and advanced inspection equipment, Stork Cooperheat offers both in-process and final visual inspection services, helping you meet both project specification and code requirements.

Radiographic Testing

Radiography (x -ray) and gamma ray technology is an efficient, reliable inspection method for NDT and identification of surface and subsurface discontinuities.

SafeRad Radiography

The SafeRad Radiography system is extremely versatile and can be used in directional panoramic and projection modes. The system's versatility and flexibility are in part due to the flexible GAMMABLOCK shielding and in part due the unique engineering design. Typical radiation controlled area barriers are 1.5 m. There are no limitations on diameter or configuration of the item to be inspected and with a capacity of up to 80 Curies of Se75 a wide application is possible. Set up is simple with no major retraining of technicians required. As the radiation controlled area is very small this allows major cost benefits in production during manufacturing and spanner work during plant shutdowns.

Ultrasonic Testing

Frequently used in thickness, corrosion inspection and examination of full penetration groove welds, ultrasonic is a highly accurate NDT detection method that proves to be extremely efficient in the field location due to the portability of the equipment and the ability to evaluate and record results at the time of inspection.

Magnetic Particle Inspection

One of the most sensitive means of detecting surface or near surface defects in ferro magnetic material. Used to inspect plate edges prior to welding, in process inspection of each weld pass or layer, post weld evaluation and to inspect repairs.

Dye Penetrated Testing

Liquid (dye) penetrates remain one of most reliable, efficient and cost effective methods for detecting flaws in the ferrous and nonferrous materials. Two types of penetrates are used, fluorescent and visible dye.

Hardness Testing

Want to know the hardness of a material, weld or component? Was the heat treatment performed correctly? Stork Cooperheat has an array of onsite field hardness testing equipment to answer these questions. The units range from the dynamic type microprocessor based Equotip in its variants, to the less sophisticated, but reliable, first principle impact devices such as Telebrineller and Poldi. Other units include Microdur, ARL and King equipment. The true benefit of the field type unit is its portability and immediate availability of results.

Ferrite Testing

Problems with ferrite content measurement? Stork Cooperheat can help using portable sophisticated ferrite meters which give digital results instantaneously, calibrated against Welding Research Council calibration blocks. Calling in Stork Cooperheat at an early stage can help prevent repeated repairs, which being undesirable at any time, are detrimental to any stainless steel thus avoiding additional cost and time involvement.

Vacuum Box Testing

This NDT method covers procedures for detecting or locating leaks, where quantitative measure is not practical. The technique is applicable to any test specimen on which a pressure differential can be created across the area to be examined. It is most useful on piping systems, pressure vessels and storage tanks. Stork Cooperheat’s main field of NDT expertise is in the inspection of welds on floor and annular plates of bulk storage tanks in the Oil & Gas and Petrochemical environments.

Holiday Testing

Holiday testing is applicable to the detection of discontinuities in non conductive coatings on metallic substrates. Where coatings have to provide an effective safeguard against corrosion, it is essential that any pinholes or flaws that will eventually lead to corrosion are detected at the earliest possible stage.

Positive Material Identification (PMI)

Stork Cooperheat offers an in situ materials identification service utilising the latest available portable equipment onsite at your fabrication shop, yard or project site. With experienced and certified technical staff, Stork Cooperheat can solve your problem with a range of advanced spectroscopic analysis instruments.
