Advanced NDT Heat Exchangers Inspection.

Unique advanced NDT Solutions for U Type pipes & Simple pipes.

Eddy Current Array (ECA) System, Using ECT/ ECA/ TECA/ RFT/ NFT/ NFA/ MFL and IRIS UT Inspection Technology.

Swiss Approval Advanced NDT laboratory testing, is using leading multi-technology instruments, for surface and tubing applications, to achieve the most versatile, reliable, and powerful Eddy Current (EC) platform solution in the market.

Our Eddy Current Array (ECA) Systems are designed to perform critical surface inspections. Their fast and easy deployment and increased probability of detection, coupled with accurate length and depth sizing and digitalised data recording ability, make ECA a competitive alternative to PT and MT.

Designed specifically for Air Conditioning (AC) and tubing inspections for Heat Exchangers, our systems are the state of the art of the International Market, related to such inspection capabilities. Our ECA inspection System, is more cost efficient than radiography/stripping, since it does not require access to both sides or surface preparation and has no health hazards.

Swiss Approval ECA Systems greatly contribute to making quality inspections easier than ever before, with any technology combination, like: ECT, ECA, TECA, RFT, NFT, NFA, MFL, or IRIS.

The maximum Eddy Current Technology (ECT) working frequency of our Systems is 10 MHz, which offers more flexibility and better performance in a variety of tubing and surface applications.

Motor drive for Rotating Pancake Coil (RPC) probes are also available. This is useful in applications where RPC probes are used to find contemporary longitudinal and circumferential cracks.

Reporting

The full inspection process is registered in an appropriate Software, and specific reports / tube number and position, are elaborated and delivered upon request, to the Customer.

Calibration Blocks

Swiss Approval holds specific calibration blocks, which are used in our Laboratory of Advanced NDT for calibration of specific NFA / NFT / RFT and IRIS probes.

Our 5 Steps Process for Heat Exchangers Advanced Inspection

Critical Client Task

Standards & Regulations: Monitor, Understand and Foresee Evolution of Standards and Technical requirements, as well identify technical related critical risk factors, at International, National, and Inter-Company level.
Inspection Logistics : Map important requirements of Inspection Team travelling, hospitality, Customs procedures, transporting of specific inspection tools, insurance, Personal Protective Equipment avaliability, Safety Regulations and approvals, local lincensing, Work Permitts, etc..
Scope of Inspection : It is very critical to understand the Scope of Inspection, defining in the most proper way, the inspection targets. Corrosion Mapping, Integrity of Base material, Welds Inspection, Coating Inspection, etc.., are different scopes of inspection and required different analysis.
Landscape: Define the complementary activities, in predefined Landscape enviroment.
Human Resourses Availability : Evaluate the human resourses aailability, either within Swiss Approval and Client structure.

Services We Provide

Standards & Regulations: We define the Standards and Regulations, according which the inspection will be implemented. We propose technical inovvations to cover such standards in the maximum efficiency level..
Inspection Logistics : We offer a package in every inspection scheduled to be performed in clients site. Travelling and Hospitality at cost. Mobil and Demobil costs, clearly defined, but Free of Charge within 1 Day of travelling by car.
Scope of Inspection : Once the scope of inspection is clearly stated and defined, Swiss Approval is starting elaborate the Technical and Economical Offer to the Client.
Landscape : In our initial /preliminary visit in Clients site, we clearly define the supporting equipment and the acceptable conditions for perform the inspection properly. Insulation removal, works in high, cleaning of surfaces, and other inspection external requirements, are clearly defined and agreeg with Client.
Human Resources Availability : Level III authorised personnel, as well Level II Inspectors, including Operators and Experts, are agreed with the Client, befor inspection.

Critical Client Task

Inspection Methodology : Depending on the type of material, the geometry, the critical conditins, the kind of inspection we are aiming to perform, inspection methodology selection, is crucial for the whole inspection proccess.
Methodologies Combination : In most of the times, we need a combination of inspection methodologies, and this is crucial for the sucess of the inspection itself. Swiss Approval is a unique Inspection Body, combining the most well known and recognised Advanced NDT methodologies, within our company, as we do not use SUB-Contractors for inspection services. We have the capacity to afront every inspection requirement, especially combined methodologies.
Tools Selection based on methodology adopted : We select our inspection tools case by case, depending on the combination of methodologies selected to implement.

Services We Provide

Inspection Methodology : We select the most suitable inspection methodology for each component /part to isnspect, including intermediate equipment.
Methodologies Combination : We also define and select combination of inspection methodologies, depending on the particular conditions for each inspection service.
Tools Selection based on methodology adopted : We guarantee the last technology tools, properly calibrated, for the highest level inspection performance posible.

Critical Client Task

BEFORE INSPECTION - Surfaces Cleaning: Before any inspection activity, the cleaning of surface has to be performed in a proper way. Removal of Insulation and Cleanig is an absolute requirement for a sucessful inspection.
DURING INSPECTION - Inspection Service : The inspection activity is performed with a calibrated Tool, by authorised Personnel, and according the inspection procedures.

Services We Provide

BEFORE INSPECTION - Surface Cleaning : Under specific conditions we can further clean the surfaces, with COLD Works Pneumatic tools, suitable to work in places and enviroments with high level of safety.
DURING INSPECTION - Inspection Service : An Inspection Team of 2 Advanced NDT inspectors, is performing the inspection, and our equipment is able to REGISTER and Save all inspection data for further elaboration and reporting

Critical Client Task

Build Evidence: Build customized evidences, during every inspection process. Registration of all inspection data, is crucial, in order to build the most representative and sutable inspection report.

Services We Provide

Build Evidence : Reporting is the most crucial of all administrative activities. Reports are signed by the operator in the field, and then technicaly reviewed by the Technical Manager, signed properly and issued with all inspection details and supporting documents, such photos, diagrams, etc..

Critical Client Task

AFTER REPORTING - ROW Data Collection: All Inspection Data are collected and registered in our Inspection Data File, each file with similar inspection methodology and inspection tools. Swiss Approval is the owner of such Row Inspection Data, and this is our great legacy, makes Swiss Approval Unique Advanced NDT services provider.
Artificial Intelligence Data Base: The similar row Data, feed an Artificial Intelligence System, in order to develop our own Swiss Approval comparition tool, and be able to preliminary assess the results, before technical Review and assessment.

Services We Provide

AFTER REPORTING - Data Collection : Data are clasiffied according the similarity criteria, and registered in Swiss Approval Data base. Similarity criteria arebased on the inspection Tools caracteristics, Methodology Criteria, Standards requirements, Geometrical parameters, Material specifications, etc..
Artificial Intelligence Data Base : Through our Artificial Intelligence System, we will be able to have a first evaluation of findings, within seconds after Inspection Activities, with AI evaluation tool.
