Conventional Inspection


Conventional NDT

Conventional non-destructive testing (NDT) has long served as the starting point in establishing or evaluating the condition of equipment. 

Our conventional NDT inspection capabilities allow us to conduct complete and thorough in-service inspections to assure the integrity of our clients’ assets with minimal to no operational interruptions.

Glacier Energy’s level-3 qualified technicians provide consultancy services to ensure fabrications are constructed in accordance with exact specifications, standards and codes. Our agile team has delivered a comprehensive range of NDT inspection and consultancy projects worldwide, often mobilising at short notice to meet tight project timescales.

Glacier Energy is heavily engaged in the inspection of welded connections for the wind turbine construction using a combination of MPI and UT techniques to ensure full weld coverage.

Magnetic Particle Inspection is carried out by applying an electrically induced magnetic field around the test item. A solution of magnetic particles is applied to identify flux leakage caused by surface or near surface defects.  Anomalies can then be assessed by our team against relevant specifications.

Dye Penetrant Inspection detects surface defects and discontinuities on non-ferromagnetic materials.

Glacier Energy technicians utilise a low viscosity red dye which penetrates into surface breaking defects or discontinuities. This is followed by removing excess dye and applying a highly absorbent developer which draws out the penetrant to the surface marking clear visible indications of surface breaking discontinuities. Our technicians will then evaluate these indications against relevant codes or specifications.

Glacier Energy has qualified Level 2 NDT technicians who carry out inspections on almost all types of engineering fabrication and assemblies to ensure professional workmanship and compliance with applicable standards.

We often perform inspections to determine the acceptability of welded fabrications and structure through the use of fiberscopes, borescopes, mirrors which may enhance the visual inspection function.

Glacier Energy has experience carrying out Positive Material Identification (PMI) using X-Ray fluorescent analysis techniques. PMI is particularly useful in verifying the chemical composition of materials, particularly in exotic pipework and weld filler metals.

Glacier Energy has extensive experience in the use of equipment to check ferrite content by measurement of magnetic permeability.

This technique is particularly useful in verifying material acceptability in castings, forgings, wrought products and weldments.

Ferrite testing is a fast, inexpensive, and accurate way to measure delta ferrite content in austenitic and duplex stainless steels. It is a technique used to measure the delta ferrite content in austenitic stainless steel and duplex stainless steel. The delta ferrite content is measured to better understand an austenitic or duplex stainless steel’s susceptibility to corrosion, susceptibility to solidification cracking and other types of material failure. Ferrite testing commonly employs magnetic induction as a means to measure the ferrite content of a material, although there are other methods that are used.

This NDT technique consists of propagating high frequency sound impulses into the test material providing clear signal interpretation through visual display of cracks and/or fabrication induced defects.

Our highly skilled technicians interpret this information against criteria associated with the relevant specifications or standards such as ASME/AWS/EN to determine acceptance or rejection against those standards or customer specification.

This same process may also be utilised to measure thickness of pipelines, vessels, bulkheads etc and for detection and monitoring of erosion, especially when there is only access from one side of the test material.

Radiographic Inspection makes use of Gamma-Ray and X-Ray radiation which pass through solid materials, such as piping and welds.

Images are generated on radiographic film which display variations in the radiation that is absorbed or transmitted, which are then assessed against applicable codes of specifications.

The use of X-Ray and Gamma rays is highly hazardous, and Glacier Energy’s team is highly trained to work under strict legislative requirements, under controlled conditions, often within specific shielded compounds or enclosures. Sealed sources are subject to control by the Environmental Agency and Health and Safety Executive.
