CHANUN Compliant Pressure‑Vessel Solutions: SPVD‑CE with Valid NB Number & ASME U‑Stamp for Global Export

Release time:

2026-08-21

When exporting air compressors to European Union and North‑American markets, pressure‑vessel compliance for air receivers and safety valves directly determines customs clearance success, local installation approval and insurance eligibility. Many suppliers only provide simple self‑declaration documents without real Notified‑Body approval. CHANUN delivers fully certified pressure‑containing components: carbon‑steel air receivers under SPVD (2014/29/EU) with valid NB‑number certification, safety valves certified under PED (2014/68/EU) also issued by a Notified Body, as well as complete ASME‑compliant packages including factory authorization, physical U‑stamp marking, official data reports and NBB‑registered NB numbers for North‑American projects.

EU Compliance: SPVD for Air Receivers and PED for Safety Valves

Two separate EU directives govern compressor pressure parts: SPVD 2014/29/EU for simple pressure vessels, and PED 2014/68/EU for pressure‑equipment accessories such as safety valves. These two directives are mutually exclusive; one component can only fall under one directive.

Carbon‑steel air receiver: SPVD 2014/29/EU Certification

CHANUN’s standard carbon‑steel air receivers satisfy all SPVD eligibility criteria: medium is air, working pressure ≤30 bar, PS×V value ≤10000 bar·L, carbon‑steel material, welded cylindrical structure without direct flame heating.

Certificated per standard EN 286‑1, issued by an EU authorised Notified Body with traceable NB number.
Valid for full EU‑wide customs clearance, on‑site installation and operation.

Note: SPVD is a legally‑valid CE route for low‑risk simple pressure vessels, equal in legal standing to PED. It is not a “lower‑grade” certification.

Safety Valve: PED 2014/68/EU Certification

Safety valves belong to pressure‑safety accessories and cannot adopt SPVD. All CHANUN matching safety valves comply with PED 2014/68/EU, assessed and certified by the same Notified Body with valid NB identifier.

Important clarification: CHANUN provides NB‑approved CE certification for pressure vessels and safety valves. Third‑party notified‑body CE certification for the complete whole compressor machine is not available. All pressure‑containing components are fully compliant for European market requirements.

How to verify valid CE documentation

Confirm directive‑to‑product matching: air receiver → 2014/29/EU SPVD; safety valve → 2014/68/EU PED.
Check harmonised standard matching: SPVD pairs with EN 286‑1; PED for safety valves follows EN ISO 4126.
Confirm valid 4‑digit NB number printed on certificates, traceable within EU NANDO database. Pure manufacturer self‑declaration without NB‑involvement is not accepted for these pressure parts.
Certificate pressure, volume, medium and material parameters must fully match the actual shipped units.

North‑America Compliance: ASME U‑Stamp, Factory Authorization and NBB‑NB Registration

For United States and Canadian industrial projects, ASME compliance is widely required by local safety authorities, insurance companies and tender specifications. Mere paper certificates are insufficient. Valid ASME compliance requires three indispensable elements: factory ASME authorization, physical steel stamping on each vessel, and official serialised data reports.

U‑stamp for air receivers: CHANUN standard carbon‑steel air receivers adopt ASME BPVC Section VIII‑1 U‑stamp certification (not UM‑stamp). Each tank carries physical U‑stamp marking on the nameplate, accompanied by original U‑1 data report for every single unit. Factory ASME authorization is kept valid with annual surveillance audits.
Safety valve compliance: Supporting safety valves are equipped with ASME UV‑stamp. For most industrial states in USA, CHANUN can supply products with completed NBB‑NB registration, the official North‑American regulatory filing.
Practical note: ASME governs pressure‑containing parts (air receiver, safety valve) rather than the compressor host itself. When clients request “ASME compressor”, it refers to ASME‑certified pressure vessels and safety valves fitted onto the machine.

Core Differentiator of CHANUN Compliance Packages

Dual‑system genuine NB‑body certification for EU market: Carbon‑steel air receiver (SPVD 2014/29/EU) and safety valve (PED 2014/68/EU) both carry valid Notified‑Body NB numbers. Many competitors only offer manufacturer self‑declaration without NB‑issuance, which risks customs detention or audit rejection in Europe.
Complete ASME deliverables for North‑America: Factory authorization, physical U‑stamp on tank, unit‑by‑unit U‑1 report, and optional NBB‑NB registration. Avoid non‑compliance risks caused by paper‑only certificates or mis‑used UM‑stamp for large‑volume tanks over 142 L.
Clear‑scope compliance boundary: Pressure‑relevant components are fully certified; whole‑machine third‑party NB‑CE is not provided. All documents match shipped product parameters one‑to‑one.
Wide product coverage: Compliant pressure parts are available for E2, EF, DKF, KF, GT, 100TA and other CHANUN screw compressor series, covering workshop‑type integrated units and industrial heavy‑duty models.

Closing Remarks

For cross‑border air‑compressor procurement, buyers shall distinguish between manufacturer self‑declaration and real Notified‑Body‑issued CE for pressure parts; for North‑American projects, physical stamping and original data reports are mandatory beyond simple certificates.
