NDT Above Ground Storage Tank & Pipeline Inspection & Testing Services

Silverwing UK Ltd is a specialist NDT inspection company concentrating on corrosion detection, sizing and servicing the storage tank and pipe line market within the Petro-Chemical industry.
Our pipe line and above ground storage tank testing and survey equipment, many developed and marketed worldwide by our in-house manufacturing division includes:
Magnetic Flux Leakage (MFL) Floor Scanners
Remote Access Ultrasonic (UT) crawlers
Long Range Ultrasonic Pipe Screening using Guided Waves
Electric Vacuum Box systems.
The Service Inspection Division’s plant is up-dated on a regular basis to ensure it always has the latest technology available. To compliment the Inspection Services, Silverwing UK Ltd is able to offer full engineering assessment of tankage to meet the guidelines laid down by EEMUA 159 and API 653 including "fitness for purpose" and inspection scheduling reports. Our personnel employ best working practices with safety a top priority. Preparation and execution of site-specific health and safety plans coupled with detailed inspection procedures ensure Silverwing UK Ltd meet both UK Health & Safety and International inspection specification requirements.

NDT Inspection Techniques and Equipment

FloormapVS2i
Tank bottom inspection with computerised MFL corrosion detection & sizing.
The motorised FloormapVS2i maintains a constant speed giving more consistent results with greater defect detectability and sizing than non-motorised systems.

MFL2000
Motorised MFL corrosion detection tank bottom scanner.
A quick and effective MFL screening tool to locate corrosion for secondary sizing inspection techniques.

Pipescan
Pipescan is a portable, magnetic flux leakage inspection system for the detection of random internal corrosion in pipe runs. MFL is not affected by product flowing through the pipe runs so surveys can be carried out both on-line and off-line.

Handscan
MFL corrosion detection mini scanner.
The Handscan MFL corrosion detection mini scanner is designed to compliment the MFL2000 and FloormapVS floorscanners.

Vacuum Box
The vacuum box test is performed on welded seams for rapid integrity evaluation. The system is highly effective and provides a rapid, economic method of evaluating the integrity of various welds.

UT
Silverwing personnel use a range of traditional irrigated and dry coupled UT inspection systems to suit specific requirements for Ultrasonic A, B and C-scan Inspection of Pressure Vessels, Tanks and Large Diameter Pipework. Remote access ultrasonic crawlers are also used to allow cost effective ultrasound thickness measurements on above ground ferro-magnetic structures without the need for costly scaffolding or rope access.

MPI
Magnetic particle inspection (MPI) is used for the detection of surface and near-surface flaws in ferromagnetic materials, to inspect a variety of product forms such as castings, forgings, and weldments.

Guided Wave Long Range UT
Long Range Ultrasonic Screening of Pipework including Corrosion Under Insulation Inspection.
