Is a SABER Certificate Required for Steel Flanges?
Yes. Pipe flanges used in water, oil, gas, process and building services are regulated on the SABER platform, primarily under the Technical Regulation for Building Materials (steel and metal group) and, for pressure-system use, the pressure-equipment framework. A Product Certificate of Conformity (PCoC) must be issued before a Shipment Certificate of Conformity (SCoC) can be obtained for each consignment and the goods cleared through Saudi customs.
Flange conformity rests on two things: the dimensional standard (bolt circle, raised face, thickness and drilling to ASME B16.5 / B16.47 or EN 1092-1) and the material test certificate (MTC / EN 10204 3.1 or 3.2) confirming the forging grade — for example ASTM A105 (carbon), A182 F304 / F316 (stainless) or A350 LF2 (low-temperature). Positive material identification (PMI) is often used to confirm the delivered flanges match the certificate.
Applicable Technical Regulations & Standards
Flanges are certified through SABER registration, and the relevant standard depends on the flange type, pressure class and material. The exact regulation and standards are confirmed at assessment from the product type and HS code.
- Dimensional standards — ASME B16.5 (NPS ½–24), ASME B16.47 Series A / B (NPS 26–60) or EN 1092-1 (PN-rated), covering face type, drilling and pressure class (150 / 300 / 600 up to 2500, or PN 6–PN 100)
- Material specifications — ASTM A105 / A182 / A350 or EN 10222 forging grades, with the grade verified against the MTC
- Technical Regulation for Building Materials — steel and metal group, where flanges are supplied for construction and building services
- Pressure-equipment requirements for flanges used on registered pressure systems and pipelines; see pressure vessels & boilers
- Material Test Certificate to EN 10204 (type 3.1 / 3.2) — the core supporting evidence of chemical and mechanical properties
Testing & Verification Requirements
- Chemical composition analysis and PMI — to confirm the forging grade
- Mechanical properties — tensile, yield, elongation and hardness; impact (Charpy) testing for low-temperature grades
- Dimensional inspection — outside diameter, bolt circle, number and size of bolt holes, raised-face height and flange thickness against the standard
- Surface-finish check of the gasket face (serrated / stock finish)
- Non-destructive examination (visual, PT / MT / UT) where the specification requires it
- Coating / galvanizing thickness where the flange is coated
A valid material test certificate from the forge, supported by dimensional and PMI verification and, where required, testing from an ISO/IEC 17025 accredited laboratory, forms the core of the evidence. We review your MTCs first and arrange only the verification product testing that is actually needed.
SABER Certificate Requirements for Steel Flanges
The typical document set for a flange SABER application is below; our full documents required guide explains each item in more detail.
- Commercial invoice and packing list
- Material Test Certificates (EN 10204 3.1 / 3.2) for each heat
- Product technical datasheet stating flange type, size range, pressure class and standard
- Dimensional inspection report against ASME B16.5 / B16.47 / EN 1092-1
- Photographs of flange marking / stamping and heat numbers
- HS code and Saudi importer registration details
How We Help
- Confirm the type, class and standard
We classify the flange and confirm exactly which dimensional standard and material specification apply.
- Review your material certificates
We check the MTC chemistry and mechanical values against the grade and flag any mismatch with the stamping.
- Coordinate verification
We arrange PMI, dimensional inspection and any mechanical or NDE testing where the certificate alone is not sufficient.
- Obtain the PCoC and process each SCoC
We secure the Product Certificate and process the Shipment Certificate for every consignment.
Frequently Asked Questions
Do steel flanges need a separate SABER certificate from pipes and valves?
Flanges can be certified on their own PCoC or grouped with related piping components, depending on how they are supplied and invoiced. Because flange conformity is driven by its own dimensional standard and forging grade, we usually assess them as a distinct product family.
Is the material test certificate enough on its own?
The EN 10204 3.1 / 3.2 certificate is essential, but the stamped grade still needs to be verifiable — typically by PMI — and the flange dimensions must be confirmed against the declared standard and pressure class. We confirm what is required at assessment.
Which flange standards are accepted?
ASME B16.5 and B16.47 (Series A and B) for inch-based class-rated flanges, and EN 1092-1 for PN-rated flanges, are the common routes. The declared standard, pressure class and facing must match the datasheet and the marking.
How much does SABER certification for flanges cost and how long does it take?
It depends mainly on whether complete material certificates are available and whether PMI, dimensional or mechanical verification is needed. When MTCs are in order and match the stamping, a PCoC can often be arranged quickly; low-temperature or high-class flanges may need impact testing and NDE, and that laboratory turnaround becomes the main variable. Send your material certificates and specification for a specific quote and timeline at no cost. See our SABER certificate cost guide.
How long is the PCoC valid, and do I need a new SCoC for every shipment?
A Product Certificate of Conformity is typically valid for one year, so a single PCoC can cover multiple shipments of the same flange range during that period. An SCoC is issued per consignment — every individual shipment needs its own Shipment Certificate before it can clear Saudi customs.
Which flange products and HS codes does this cover?
Steel flanges are generally classified under HS heading 7307 (tube or pipe fittings of iron or steel), with sub-headings distinguishing stainless (7307.21 flanges) from other steel (7307.91 flanges). The precise HS code, grade and standard determine which requirements apply, so we confirm the classification during assessment.
