OUR TUBE STANDARDS FOR ECT RFT NFT MFL IRIS NFA
Service Overview
We manufacture and supply tube reference standards for
multiple tube-inspection technologies including Eddy Current Testing (ECT),
Remote Field Testing (RFT/RFET), Near Field Testing (NFT), Magnetic Flux
Leakage (MFL), IRIS ultrasonic inspection and Near Field Array (NFA)
applications where technically suitable. Each standard is designed around tube
material, dimensions, probe configuration and reference-feature requirements.
Scope of Service

tube material, OD, wall thickness and method compatibility.
2. Define
single-method or multi-method standard requirements.
3. Select
internal and external reference features with adequate spacing.
4.
Coordinate probe, centring and support-plate requirements where
relevant.
5. Provide
drawings, flaw schedules and verification records as agreed.
Available Specimen and Component Configurations
1.
Non-ferromagnetic ECT tubes.
2.
Ferromagnetic RFT/RFET, NFT and MFL tubes.
3. IRIS
calibration and demonstration tubes.
4.

Flaws, Reflectors or Conditions Covered
1.
Through-holes and flat-bottom holes.
2. Internal
and external grooves.
3. Axial
and circumferential notches.
4.
Localised wall-loss, thinning and pit-type reflectors.

NDT methods where technically applicable. Final suitability is confirmed
against the material, geometry, target condition and intended equipment
configuration.
1. ECT and
ECA.
2.

Refineries, petrochemical and chemical plants.
3. Boilers
and heat-exchanger manufacturers.
4. Marine
and offshore.
5. NDT
equipment manufacturers, service companies and training centres.
Applicable Codes, Standards and References
The work may be designed, manufactured or performed with
reference to the following, as applicable to the agreed scope:
1. ASME,
ASTM and customer tube-inspection references where applicable.
2. ISO/EN
references where specified.
3. OEM and
asset-owner procedures.
4. Approved
project drawings and acceptance criteria.
The customer should identify the exact document, edition and
revision. Reference to a standard does not by itself constitute certification,
accreditation or approval by the issuing body.
Project Workflow
1. Requirement Review: Review the
application, method, component, material, geometry, equipment and intended use.
2. Technical Definition: Confirm drawings,
dimensions, flaw or reflector schedule, tolerances, access and documentation
requirements.
3. Design Approval: Issue the proposed
technical basis or layout for customer review where custom manufacture is
required.
4. Manufacturing or Service Execution:
Complete fabrication, machining, flaw introduction, marking, inspection or
preparation under controlled instructions.
5. Verification: Check agreed dimensions,
identification, reflector locations and relevant NDT responses using suitable
methods.
6. Documentation and Delivery: Compile
agreed records, protect the items and arrange domestic or international
dispatch.
Documentation and Deliverables
Depending on the agreed scope, the deliverable package may
include:
1. Approved
drawing or technical layout, where applicable.
2. Material
and component information, where included.
3. Flaw,
reflector or reference-feature schedule and location map.
4.
Dimensional inspection record.
5. NDT
verification record, where included.
6. Unique
identification, engraving or labelling details.
7.
Photographic record where requested.
8.
Certificate of conformity for the agreed manufacturing or service scope.
9. Packing,
preservation and handling information.
Why Choose NDE Flaw Tech India?
1.
Application-specific engineering rather than one-size-fits-all
selection.
2. Support
for conventional and advanced NDT methods where technically applicable.
3.
Controlled machining, flaw introduction, identification and custom
fabrication capabilities.
4. Open,
blind and partially blind documentation options for training and assessment
programmes.
5.
Traceable drawings, flaw maps, dimensional records and verification
information when included in the scope.
6. Support
for domestic and international customers, subject to logistics and applicable
restrictions.
Information Required for a Technical and Commercial Proposal
1. Tube
material and magnetic properties.
2. Outside
diameter, wall thickness and length.
3.
Inspection method or methods.
4. Probe,
sensor and equipment details.
5. Required
reflector type, depth, size and location.
6.
Support-plate or fin configuration where applicable.
7.
Applicable procedure and documentation scope.
Technical Limitations and Responsibilities
1. A single
physical standard may not provide equivalent response for every NDT method.
2. Feature
geometry may need to be adjusted for method sensitivity and tube wall
thickness.
3.
Ferromagnetic and non-ferromagnetic tube methods require different
material considerations.
4. Probe
centring, fill factor and support structures can affect response.
5. Final
calibration acceptance must follow the applicable inspection procedure.
Frequently Asked Questions
Can one tube be used for ECT and IRIS?
Sometimes, if material and reference-feature design are
compatible with both techniques. A technical review is required.
Can you manufacture standards for ferromagnetic tubes?
Yes. RFT/RFET, NFT, MFL and other applicable standards can
be designed for suitable ferromagnetic tubing.
Can ID and OD wall loss be included?
Yes, subject to wall thickness, feature spacing and
machining access.
Can support plates be simulated?
Yes. Support-plate or fixture sections can be incorporated
where they are important to the inspection response.
What is NFA?
In this context NFA refers to Near Field Array applications.
The exact probe and procedure should be supplied so the standard can be
designed appropriately.
Request a Proposal
Send the tube material, dimensions, inspection method(s),
probe information and required reference features. We will propose a
single-method or multi-method tube standard with an agreed documentation
package.
