Glacier Energy Services boosts advanced non-destructive testing team with senior hire

GLACIER Energy Services has appointed industry-leading engineer Mr Alastair Gibbons to the senior operations team of its non-destructive testing (NDT) business, Professional Testing Services, boosting the firm’s leadership as it expands its use of advanced techniques.

With decades of experience, PTS offer a range of comprehensive non-destructive testing and inspection services to the oil and gas, renewable energy and power generation industries, both in the UK and overseas.

Advanced Inspection Services

Professional Testing Services (PTS) provide tube testing solutions through differing complimentary Advanced NDT techniques in order to give you an insight into the tube condition of your heat exchangers. With this conditional information, preventative maintenance can be planned and carried out such as plugging or re-tubing.

We can inspect the tubes in a wide range of exchangers including coolers, condensers, boilers and heaters. Covering the majority of materials-both ferritic and non-ferritic, sizes and dimensions of upwards of 8mm ID to greater than 75mm and wall thickness from less than 1mm up to 20mm, we can provide a suitable solution for you.

PTS uses state-of-the-art non-destructive testing equipment and new probe “array” technology and experienced technicians qualified to PCN L2 in accordance with EN ISO 9712, with provision of dedicated PCN Level 3’s to supervise NDT staff where required.

Our tube inspection techniques include:

  • Eddy current & Eddy Current Array for Stress Corrosion Cracking Detection
  • Remote Field Eddy Current
  • Partial or Magnetically Saturated Eddy Current
  • Near Field and Near Field Array Technology
  • IRIS

In addition to our Specialist Tube Inspection Solutions, PTS Limited, offer:

  • Phased Array UT
  • Time of Flight Diffraction (ToFD)
  • Corrosion Mapping Solutions
  • Pulsed Eddy Current for Corrosion Under Insulation Inspection (CUI). 

 

  

 

Professional Testing Services can also provide Asset/Project surveys, carried out by our experienced level 3 NDT technicians to provide advisory actions for clients prior to the start of a project.  

Consultancy Services

PTS is pleased to offer its Consultancy Service utilising it's 9 NDT Level 3-qualified personnel.  They ensure fabrications are constructed in accordance with your specifications, meeting your exacting requirements and standards (ASME/AWS/EN etc).

PTS' NDT Level 3-qualified personnel have extensive experience in:

  • Interpretation of project specifications
  • Development of NDE/inspection procedures specific to your project
  • Providing advice regarding over onerous specification requirements & proposing alternative technical solutions and mitigations
  • Providing advice on various inspection techniques, methods and procedures if not previously identified or clearly specified
     
Ultrasonic Inspection

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. The highly skilled NDT 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/monitoring of erosion especially when there is only access from one side of the test material.

Radiographic Inspection (Gamma & X-Ray)

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

Images are generated on radiographic film which display variation in the radiation absorbed/transmitted and which are assessed against applicable codes or specifications.

The use of X-ray and Gamma rays is highly hazardous and our skilled technicians 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 the Health and Safety Executive.

Magnetic Particle Inspection

Magnetic Particle Inspection is used for the detection of surface breaking discontinuities or defects on ferromagnetic materials. The 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, and resulting indications can be assessed by our technicians against relevant specifications.

Dye Penetrant Inspection

Dye Penetrant Inspection detects surface defects and discontinuities on non-ferromagnetic materials e.g. stainless steel, duplex components etc.

Our technicians utilise a low viscosity dye (red) which penetrates into surface breaks or discontinuities in the test item. This is followed by a highly absorbent developer which draws any excess penetrant to the surface making clear visible indications of surface breaking discontinuities. The technicians will then evaluate these indications against relevant codes or specifications to determine acceptability.

Visual Inspection

PTS have skilled NDT technicians (qualified to Level 2) who carry out inspections on almost all types of engineering fabrication and assemblies to ensure professional workmanship and that compliance with applicable standards has been achieved. PTS often perform inspections to determine the acceptability of welded fabrications and structures through the use of fiberscopes, boroscopes, mirrors etc which may enhance the visual inspection function.

Positive Material Identification

PTS have extensive experience of carrying out PMI using X-ray fluorescent analysis techniques. PMI is particularly useful in verifying the chemical composition of materials, particularly in exotic (stainless, duplex etc) pipework and weld filler metals.

Ferrite Testing

PTS have extensive experience in the use of equipment used to check ferrite content by measurement of magnetic permeability. This technique is particularly useful in verifying material acceptability in castings, forgings, wrought products (pipes, fittings etc) and weldments.

Hardness Testing

PTS provide hardness testing on materials, which is the measurement of “Resistance of metal to deformation, usually by indentation. This method of inspection is regularly used to ascertain material acceptability to internal standards.
