Flange Inspection, Testing & Certification
Quality inspection is an important part of supplying reliable industrial flanges. Before dispatch, flange requirements can be checked for material identification, dimensions, workmanship, marking and documentation according to the applicable purchase specification.
Vandan Alloys supports inspection and documentation requirements for industrial flanges supplied to domestic and international customers.
Flange Quality Inspection
Flange inspection helps verify that the supplied product matches the agreed material grade, dimensions, flange type, pressure class and applicable standard.
Inspection requirements may vary according to the product specification, project requirements and customer's purchase order.
Typical inspection activities can include:
Visual Inspection, Dimensional Inspection, Material Verification, Marking Verification and Documentation Review.
Flange Dimensional Inspection
Dimensional accuracy is important for proper flange installation and alignment.
Depending on the flange type and standard, dimensions may include:
Outside Diameter, Flange Thickness, Bore Diameter, Bolt Circle Diameter, Number of Bolt Holes, Bolt Hole Diameter, Face Diameter, Hub Dimensions and Overall Length.
Dimensions are checked against the applicable drawing, standard or approved specification.
Visual Inspection of Flanges
Visual inspection is carried out to identify visible conditions that may affect the flange or its intended application.
Inspection can include checking:
Surface condition
Machining quality
Flange face condition
Bolt holes
Weld neck and hub areas, where applicable
Marking and identification
General workmanship
The acceptance criteria depend on the applicable specification and purchase requirements.
Material Verification
Correct material identification is essential when supplying alloy and stainless steel flanges.
Material verification may involve reviewing the material certificate and checking the supplied product against the specified:
Material Grade, Heat Number, Chemical Composition and Mechanical Properties.
For specific project requirements, additional material verification or testing can be arranged.
Chemical Composition Testing
Chemical analysis verifies the elemental composition of the flange material against the applicable material specification.
Depending on the requirement, the certificate or test report may include elements such as:
Carbon, Manganese, Silicon, Chromium, Nickel, Molybdenum and other elements specified for the particular grade.
The acceptance limits depend on the applicable ASTM, ASME, EN or other material specification.
Mechanical Testing
Mechanical properties are important for confirming the suitability of the material for the specified application.
Depending on the applicable material specification, mechanical testing may include:
Tensile Strength, Yield Strength and Elongation.
Additional testing requirements may apply depending on the grade, specification or project.
PMI Testing for Flanges
Positive Material Identification (PMI) can be used for selected orders where additional verification of alloy composition is required.
PMI is particularly useful for identifying alloying elements in stainless steel, duplex, super duplex and nickel alloy flanges.
PMI requirements should be specified before inspection so that the appropriate procedure can be arranged.
Hardness Testing
Hardness testing may be carried out when required by the material specification, project specification or customer purchase order.
The required hardness range and test method depend on the applicable material standard.
Heat Number & Material Traceability
Heat number traceability helps connect the supplied flange with its material test documentation.
Where required, the heat number can be associated with the product identification and corresponding material certificate.
This provides useful traceability for industrial projects, quality records and inspection documentation.
Flange MTC – Material Test Certificate
A Material Test Certificate (MTC) provides material information and test results associated with the supplied product.
Depending on the order requirement, documentation may include:
Material grade
Heat number
Chemical composition
Mechanical properties
Heat treatment information, where applicable
Product identification
Applicable material specification
EN 10204 Type 3.1 Certificate
EN 10204 Type 3.1 is commonly requested for industrial and export orders requiring certified material documentation.
A Type 3.1 certificate provides documented inspection results associated with the supplied material and is issued in accordance with the applicable certification requirements.
The exact certificate contents depend on the material specification and purchase order.
Third-Party Inspection for Flanges
Third-Party Inspection (TPI) can be arranged when required by the customer or project.
A customer's nominated inspection agency can inspect the products according to the agreed inspection and test plan or purchase specification.
Inspection may include:
Material Certificate Review, Dimensional Inspection, Visual Inspection, Marking Verification and other specified tests.
Flange Inspection Before Dispatch
Inspection requirements can be completed before dispatch according to the agreed order requirements.
The inspection process may verify:
Quantity, Flange Type, Material Grade, Dimensions, Facing, Marking, Packing and Required Documentation.
This helps ensure that the shipment is prepared according to the confirmed purchase requirements.
Flange Marking & Identification
Proper product identification helps maintain traceability during handling, installation and future maintenance.
Depending on the applicable standard and customer requirement, marking may include:
Manufacturer Identification, Material Grade, Size, Pressure Class, Standard and Heat Number.
Marking requirements are confirmed according to the applicable specification.
Export Documentation for Flanges
For international shipments, documentation can be prepared according to the customer's order and export requirements.
Depending on the shipment, documents may include:
Commercial Invoice
Packing List
Material Test Certificate
Inspection Documents
Certificate of Origin, where required
Shipping Documents
Other project-specific documentation
Exact documentation requirements should be confirmed before dispatch.
Inspection Requirements for Stainless Steel Flanges
Stainless steel flange inspection may include material verification, dimensional inspection, visual examination and certificate review.
For grades such as 304, 304L, 316, 316L, 321, 347, 310, 310S and 904L, documentation and testing can be arranged according to the applicable specification.
Inspection Requirements for Duplex & Super Duplex Flanges
Duplex and super duplex materials may have additional project-specific requirements.
For Duplex 2205 and Super Duplex 2507, customers may specify additional testing, PMI, hardness or other verification requirements.
All testing should be performed according to the applicable material and project specification.
Inspection Requirements for Nickel Alloy Flanges
Nickel alloy flange requirements may involve detailed material verification and documentation.
Grades such as Inconel, Incoloy, Monel and Hastelloy can require specific chemical, mechanical or other testing depending on the grade and purchase specification.
Quality Documentation for International Buyers
International customers may require detailed product documentation for quality records and project approval.
Vandan Alloys can support documentation requirements based on the customer's purchase order, technical specification, inspection plan and applicable standards.
The required documents should be finalized before order processing to avoid delays during inspection or dispatch.
