SIST EN 16753:2016 - Gas cylinders - Periodic inspection and testing, in situ (without dismantling) of refillable seamless steel tubes of water capacity between 150 l and 3 000 l, used for compressed gases

Overview

EN 16753:2016 - Gas cylinders: Periodic inspection and testing, in situ - defines requirements for the periodic, on‑site (without dismantling) inspection and testing of refillable seamless steel tubes with a water capacity between 150 l and 3 000 l, used for compressed and liquefied gases. The standard specifies a combination of non‑destructive examination (NDE) techniques (for example visual examination, acoustic emission (AE) testing and ultrasonic testing (UT)) to determine whether vessels can continue in service. It applies only where removal of the vessel would be hazardous or would cause unacceptable plant downtime, and excludes pressure receptacles used for transport (TPED).

Key Topics

  • Scope and applicability: In‑situ inspection of seamless steel pressure vessels 150–3 000 l; only where design allows all required inspections and removal is impractical or unsafe.
  • NDE techniques: Use of combined methods - visual inspection, AE testing, ultrasonic thickness and flaw detection, hydraulic testing, magnetic particle, radiography, eddy current, hardness and supplementary dye‑penetrant methods as needed.
  • Operational principles:
    • Mandatory pre‑inspection site visit and questionnaire to assess installation, gas type, pressure ratings, accessibility, and risk.
    • On‑site inspection sequence and decision logic for follow‑up tests if anomalies are found.
    • Safety and environmental considerations (noise, vibrational background for AE).
  • Personnel and reporting: Qualification of NDE personnel per referenced certification standards; marking, certification and formal test reports required.
  • Rejection and remediation: Annex A provides defect descriptions and rejection criteria for visual findings; provisions for rendering tubes unserviceable if required.
  • Annexes:
    • Annex A - defect evaluation and rejection criteria
    • Annex B - AE examination procedure and real‑time evaluation
    • Annex C - recommended time intervals when no national regulation exists
    • Annex D - pre‑inspection site survey/checklist and risk analysis

Applications

EN 16753:2016 is intended for use by:

  • Plant owners and asset managers with fixed high‑capacity gas vessels (offshore/onshore storage, diving systems, emergency evacuation vessels, research and medical installations).
  • Inspection bodies and certified NDE technicians performing periodic on‑site assessments.
  • Maintenance engineers, safety managers and regulators who need a documented scheme of examination for in‑situ pressure vessels. Practical benefits include reduced downtime, safer inspections where removal is hazardous, and a standardized approach to combining AE/UT/visual methods to assess structural integrity.

Related Standards

  • EN ISO 16148 (AE and UT procedures for refillable seamless steel tubes)
  • EN ISO 9712 (NDT personnel qualification and certification)
  • EN ISO 11120 (design/certification of gas cylinders) - referenced for context
  • EN ISO 25760, ISO 6406 and TPED (transport exclusions)

The article discusses the European Standard EN 16753:2016, which specifies requirements for inspecting and testing seamless steel pressure vessels (tubes) used for compressed and liquefied gases. The standard focuses on using non-destructive examination techniques such as visual examination, acoustic emission testing, and ultrasonic testing without dismantling the vessels. However, this standard only applies to pressure vessels installed in locations where removal would be hazardous or hinder continuous operation, and it does not apply to pressure receptacles used for gas transport. Additionally, the standard only applies to vessel assemblies that allow for all necessary inspections.
