Overview
Pressure vessels and boilers are engineered, fabricated items whose safety is proven by an evidence trail, not by testing a sample to destruction. The certificate turns on whether the design has been calculated and verified to a recognised code for the design pressure, temperature and contents; whether the materials are traceable to mill certificates of the right grade; whether the welding was done to qualified procedures by qualified welders; whether the non-destructive examination (RT, UT, PT, MT) meets the code's acceptance criteria; whether the completed vessel passed its hydrostatic or pneumatic pressure test; and whether the nameplate, marking and data report record all of this correctly.
Pressure equipment above the regulation's threshold limits is certified through SABER registration under the Pressure Equipment Technical Regulation. A Product Certificate of Conformity (PCoC) is issued for the equipment and a Shipment Certificate of Conformity (SCoC) is required for each consignment before it can clear Saudi customs. Air receivers built into air compressors are covered on the compressor page where the compressor is the product; a receiver, tank or exchanger supplied on its own is covered here.
Product Types
The SABER route and the Pressure Equipment Technical Regulation cover:
- Unfired pressure vessels — separators, accumulators, columns, reactors, drums and knock-out pots
- Air receivers and compressed-air / compressed-gas tanks
- Storage vessels for LPG, ammonia, CO2 and other liquefied or compressed gases
- Shell-and-tube, plate and air-cooled heat exchangers
- Steam boilers — fire-tube and water-tube — and hot-water boilers above the pressure / temperature threshold
- Economisers, superheaters, deaerators and steam drums
- Autoclaves, sterilisers and vulcanising / curing vessels
- Expansion vessels, pulsation dampeners and surge tanks
- Pressure piping assemblies and manifolds above threshold
- Safety accessories — safety / relief valves, bursting discs, pressure-limiting and monitoring devices
The scope of the certificate is defined from the design pressure and temperature, the fluid group (dangerous or non-dangerous), the volume or DN, the material and the code of construction, so it matches the equipment as fabricated. Very small vessels below the threshold limits may follow sound engineering practice with reduced formality — we confirm the category at assessment.
HS Codes
Pressure equipment is classified mainly in Chapter 84. These are examples only — the correct code depends on the exact equipment.
- 8402 — Steam or other vapour generating boilers (excluding central-heating hot-water boilers); super-heated water boilers
- 8403 — Central-heating boilers (other than those of 8402)
- 8404 — Auxiliary plant for use with boilers (economisers, super-heaters, condensers)
- 8419.50 — Heat exchange units
- 8419.89 — Other machinery, plant and equipment for treatment of materials by a process involving a change of temperature (process vessels, reactors, autoclaves)
- 7311 — Containers for compressed or liquefied gas, of iron or steel (larger static tanks; small transportable cylinders have their own requirements)
- 8481.40 — Safety or relief valves
Applicable Saudi Requirements
Pressure vessels and boilers are certified through SABER registration under the Pressure Equipment Technical Regulation. The main requirements are:
- A valid PCoC covering the vessel or boiler and its design parameters
- An SCoC for each shipment before customs clearance
- A design calculation report to a recognised code — ASME BPVC Section VIII Div 1 or 2 (unfired vessels), ASME BPVC Section I (power boilers), EN 13445 (unfired) or EN 12952 / EN 12953 (boilers), or an equivalent national code applied consistently
- Material test certificates (EN 10204 3.1, or 3.2 where the code or category requires third-party endorsement) for all pressure-retaining parts
- Qualified welding procedure specifications (WPS) with supporting PQRs, and welder / operator qualification records
- Non-destructive examination reports — radiography, ultrasonic, penetrant and magnetic-particle — to the extent the code and joint category require
- Post-weld heat treatment records where required by thickness or material
- A hydrostatic (or, where justified, pneumatic) pressure test certificate at the code test pressure
- Sized and certified pressure-relief devices matched to the vessel
- A durable nameplate / stamp recording the manufacturer, code, design pressure and temperature, MAWP, test pressure, capacity, year and serial number; and a manufacturer's data report (for example ASME U-1 / U-1A)
- An operating and maintenance manual in Arabic and a registered Saudi importer on the SABER platform
Technical Regulation
Pressure vessels and boilers are assessed under Saudi Arabia's Pressure Equipment Technical Regulation, which sets essential safety requirements for equipment with a maximum allowable pressure above 0.5 bar gauge and applies a conformity route that scales with the hazard — a function of the pressure, the volume (or nominal size for piping) and whether the contents are a dangerous or non-dangerous fluid. Higher categories require greater third-party involvement in design review and fabrication surveillance. Design and construction are demonstrated to a recognised code: ASME BPVC Section VIII Division 1 or 2 for unfired vessels, ASME BPVC Section I for power boilers, or the European set EN 13445 (unfired pressure vessels), EN 12952 (water-tube boilers) and EN 12953 (shell boilers). Welding follows ASME Section IX or ISO 15614 / ISO 9606; NDE follows the code plus ISO 17636 (RT), ISO 16810 / ISO 17640 (UT), ISO 3452 (PT) and ISO 17638 (MT); relief devices follow API 520 / 521 / 526 or ISO 4126. Safety accessories and gas cylinders have their own requirements. The exact code, category and inspection route are confirmed at assessment. Our Technical Regulations guide explains how regulations are matched to products.
Testing / Standards
What is required depends on the equipment and its category. Typical work includes:
- Design calculation review — shell and head thickness, nozzle reinforcement, flange rating, external pressure / buckling, wind and seismic where relevant, fatigue for cyclic service
- Material verification — grade, heat number and traceability against the mill certificates; PMI where specified
- Welding review — WPS / PQR qualification range, welder certificates, weld map
- Witness or review of non-destructive examination and its acceptance
- Post-weld heat treatment charts and hardness surveys
- Hydrostatic / pneumatic pressure test witness at the code test pressure, with hold time and leak check
- Relief-device sizing check and set-pressure test certificate
- For boilers — additional controls, low-water cut-off, safety valve capacity and commissioning checks
- Final visual, dimensional and nameplate verification
Existing manufacturer records and third-party inspection reports are accepted where they cover the exact equipment and code. We review your dossier before arranging any additional testing or inspection, so effort goes only where evidence is missing.
Documents Required
A typical pressure-equipment application uses the set below; our full documents required guide explains each item.
- Commercial invoice and packing list
- HS code of the equipment
- Design data sheet — design pressure and temperature, MAWP, corrosion allowance, fluid and fluid group, capacity
- Design calculation report and general-arrangement / detail drawings
- Code of construction and edition
- Material test certificates (EN 10204 3.1 / 3.2) for pressure-retaining parts
- WPS, PQR and welder qualification records; weld map
- NDE procedures and reports (RT / UT / PT / MT)
- PWHT records where applicable
- Hydrostatic / pneumatic test certificate
- Relief-device sizing calculation and set-pressure certificates
- Manufacturer's data report and nameplate rubbing / photo
- Declaration of conformity, Arabic operating manual and Saudi importer registration
PCoC Process
The Product Certificate of Conformity certifies the vessel or boiler against the applicable code and the Technical Regulation. In outline:
-
Category and code
We confirm the design pressure and temperature, the fluid group, the volume or DN, the resulting hazard category, the code of construction, the HS code and the scope of certification.
-
Design review
The design calculation report and drawings are reviewed against the code for the stated parameters.
-
Fabrication records and inspection
Material certificates, welding qualifications, NDE, PWHT and the pressure test are reviewed, with witness inspection where the category requires it.
-
Technical review
An approved certification body reviews the complete dossier and the nameplate / data report against the regulation.
-
PCoC issued
Once the review is satisfied, the PCoC is issued on the SABER platform. It is typically valid for one year.
SCoC Process
A Shipment Certificate of Conformity is issued per consignment and is what customs checks at the border. In outline:
-
Shipment details submitted
The invoice, packing list with the equipment and serial numbers, and the linked PCoC are submitted for the specific consignment.
-
Verification
The shipment is verified against the valid PCoC, the equipment is checked against the certified design and nameplate, and the SCoC fee is settled on the platform.
-
SCoC issued
The SCoC is issued for that shipment, allowing it to clear Saudi customs. Each new shipment needs its own SCoC.
Certification Timeline
The main variable is whether a complete design and fabrication dossier already exists. Our SABER timeline guide covers the general process.
- With a complete code design report, full material traceability, welding and NDE records and a witnessed pressure test — a PCoC can typically be arranged within one to three weeks
- When design calculations must be produced or verified, or fabrication surveillance / witness inspection is needed for a higher category — allow several weeks
- Third-party involvement in design examination for the highest categories should be started early in the build programme
- SCoC — normally issued quickly per shipment once a valid PCoC is in place
Common Problems
- No design calculation report, or a report that does not match the design pressure / temperature on the nameplate
- Material certificates missing, or not traceable to the parts by heat number
- Welding done without a qualified WPS, or welders without current qualification for the process and position
- NDE extent below what the code requires for the joint category
- Codes mixed — ASME allowable stresses with EN joint factors, or a code stamp the fabricator is not authorised to apply
- No hydrostatic test certificate, or a test below the code test pressure
- Relief device not sized for the vessel, or no set-pressure certificate
- Nameplate incomplete or not matching the data report
We check these points before the equipment ships — above all the design report, the material traceability and the pressure-test record — so the certification is not held up for avoidable reasons.
Frequently Asked Questions
Is a pressure vessel type-tested like an appliance?
No. There is no destructive type test of a sample. A pressure vessel or boiler is certified on its design and fabrication evidence — the calculation report to a recognised code, material certificates, qualified welding, non-destructive examination, the hydrostatic pressure test and the nameplate / data report. The certificate confirms that trail is complete and consistent.
Which construction codes does Saudi Arabia accept?
ASME BPVC Section VIII Division 1 or 2 for unfired vessels and Section I for power boilers, or the European set EN 13445 for unfired vessels and EN 12952 / EN 12953 for boilers, are all recognised — provided the chosen code is applied consistently and the fabricator is authorised to certify to it. Equivalent national codes may be accepted on the same basis. The code is confirmed at assessment.
What decides how much third-party involvement is needed?
The hazard category, which is set by the maximum allowable pressure, the volume (or nominal size for piping) and whether the fluid is dangerous or non-dangerous. A small air receiver on non-dangerous service is a low category with mostly documentary review; a large vessel on a dangerous gas is a high category needing design examination and fabrication surveillance by an approved body.
Is the air receiver on my compressor covered here?
If the compressor is the product being certified, the built-in air receiver is assessed as part of the compressor — see our air compressors page. If you are supplying a receiver, buffer tank, exchanger or process vessel on its own, it is certified as pressure equipment under this page.
How much does SABER certification for a pressure vessel cost and how long does it take?
It depends on the hazard category and whether the design report, material traceability, welding / NDE records and pressure-test certificate are complete. With a full dossier a PCoC can often be arranged within one to three weeks; producing or verifying design calculations, or arranging witness inspection for a higher category, adds several weeks. Send your design data sheet and manufacturing records for a specific quote and timeline at no cost. See our SABER certificate cost guide.
Do safety valves and small gas cylinders need separate certification?
Safety and relief valves are safety accessories with their own conformity requirements and are usually certified alongside the vessel they protect. Small transportable gas cylinders follow the transportable pressure-equipment rules rather than this route. We confirm the correct path for each item at assessment.
