SIST EN 12007-2:2013は、ポリエチレン（PE）パイプラインに関する特定の機能要件を定めており、ガスインフラストラクチャの一部として重要な役割を果たします。この標準は、最大運転圧力（MOP）が10バールまでの範囲を対象としており、-20 °Cから+40 °Cの間の運転温度を考慮しています。 この標準の強みは、PEパイプの多様性をカバーしている点です。具体的には、識別ストライプを含むPEパイプ、外側または内側に共押出層を持つPEパイプ、外側に剥がし可能な連続熱可塑性追加層を持つPEパイプを扱います。このように、異なるタイプのパイプに対する具体的な要件を設定することで、利用者は特定の用途に応じた適切な選択を行うことができます。 さらに、EN 12007-2:2012は、ガスインフラストラクチャに関連する基本的な原則を定めており、CEN加盟国における国別標準や実施基準との相互適用性を考慮しているため、実務上の柔軟性も持っています。国の法律や規制がより厳しい要件を提示している場合、国の法律が優先されることも明確にされており、現場での適応が容易です。 この文書は、ガスインフラストラクチャの安全性と効率性を向上させるための基盤を提供しているため、業界関係者にとって非常に関連性の高い標準です。すべての利害関係者がこれらの特定の要件を理解し、遵守することで、ガス供給の安全性が確保されることが期待されます。
Die europäische Norm EN 12007-2:2012 behandelt die spezifischen funktionalen Anforderungen für Polyethylen (PE) Pipelines, die für einen maximalen Betriebsdruck (MOP) von bis zu und einschließlich 10 bar ausgelegt sind. Sie ergänzt die allgemeinen funktionalen Anforderungen der EN 12007-1 und fokussiert sich auf wichtige Aspekte wie die Betriebstemperatur, die zwischen -20 °C und +40 °C liegen darf. Eine der herausragenden Stärken der EN 12007-2:2012 ist die klare Abgrenzung der verschiedenen Typen von PE-Rohren, die in der Norm berücksichtigt werden. Diese beinhalten nicht nur herkömmliche PE-Rohre mit Kennzeichnungsstreifen, sondern auch solche mit co-extrudierten Schichten sowie Rohre mit abziehbaren thermoplastischen Zusatzschichten. Diese Differenzierung ermöglicht eine gezielte Anwendung der Norm in verschiedenen Szenarien der Gasinfrastruktur und trägt dazu bei, dass die spezifischen funktionalen Anforderungen optimal erfüllt werden können. Ein weiteres wesentliches Merkmal dieser Norm ist die Festlegung gemeinsamer Grundprinzipien für die Gasinfrastruktur. Dies ist besonders relevant, da sie die Basis für die Anwendung in Verbindung mit nationalen Standards und/oder Praktiken in den CEN-Mitgliedsländern bildet. Die Norm hebt die Wichtigkeit hervor, dass Nutzer sich der bestehenden nationalen Standards bewusst sind, um die örtlichen rechtlichen Rahmenbedingungen und spezifischen Anforderungen zu berücksichtigen. Dies fördert nicht nur die Einhaltung, sondern auch die Sicherheit und Effizienz in der Anwendung der PE-Pipelines. Ein zusätzliches starkes Element der EN 12007-2:2012 ist der Hinweis, dass im Falle von Konflikten zwischen nationalen Regelungen und den Anforderungen dieser europäischen Norm die nationalen Vorschriften Vorrang haben sollten. Dies zeigt deutlich, dass die Norm flexibel und anpassungsfähig ist, um den unterschiedlichen gesetzlichen Anforderungen der Mitgliedstaaten gerecht zu werden. Zusammenfassend lässt sich sagen, dass die EN 12007-2:2012 nicht nur einen klaren Rahmen für die spezifischen funktionalen Anforderungen an Polyethylen Pipelines bietet, sondern auch relevante Aspekte für die Umsetzung in der Praxis thematisiert. Ihre Relevanz in der Gasinfrastruktur ist unbestreitbar, da sie auf die modernen Anforderungen und die unterschiedlichen technischen Gegebenheiten reagiert und somit einen entscheidenden Beitrag zur Sicherheit und Zuverlässigkeit von Gasversorgungssystemen leistet.
EN 12007-2:2012 표준은 최대 운영 압력이 10 바까지 정치화공(PE) 파이프라인의 특정 기능 요구 사항을 설명하는 중요한 문서입니다. 이 표준의 범위는 -20°C에서 +40°C 사이의 운영 온도를 포함하여, 일반 기능 요구 사항을 제정한 EN 12007-1의 내용을 보완합니다. 이 표준은 세 가지 유형의 PE 파이프를 다루고 있습니다. 첫째, 식별 스트라이프가 포함된 PE 파이프; 둘째, 내부 또는 외부 또는 둘 다에 공동 압출층이 있는 PE 파이프; 셋째, 표면에 부착 가능한 연속 열가소성 추가 층이 있는 PE 파이프입니다. 이러한 유형의 구분은 사용자가 다양한 적용 분야에 맞춰 적합한 리소스를 선택하는 데 도움을 줍니다. EN 12007-2:2012의 강점 중 하나는 가스 인프라의 공통 기본 원칙을 명확히 하고 있다는 점입니다. 이는 사용자들이 자신의 국가에서 더 세부적인 표준이나 실천 강령이 존재할 수 있음을 알고, 이를 참고하여 더욱 안전하고 효과적으로 PE 파이프를 설계하고 설치할 수 있도록 합니다. 이 표준은 CEN 회원국의 국가 표준 및 실천 강령과 함께 적용될 것을 권장하며, 국가별 법령 및 규정이 EN 12007-2:2012의 요구 사항보다 더 엄격한 경우 국가 법령이 우선 적용됨을 명시하고 있습니다. 이러한 사항은 FprCEN/TR 13737-1에서 구체적으로 설명되어 있으며, 다양한 국가 법령의 적용 가능성에 대한 명확한 정보를 제공합니다. 결론적으로, EN 12007-2:2012 표준은 PE 파이프라인의 설계 및 운영에 있어 필수적인 기준을 제시하며, 그 범위와 강점을 통해 가스 인프라의 안전성과 신뢰성을 높이는 데 기여하고 있습니다.
La norme EN 12007-2:2012 définit les exigences fonctionnelles spécifiques pour les pipelines en polyéthylène (PE) spécifiquement pour une pression de fonctionnement maximale (MOP) allant jusqu'à 10 bar. Son domaine d'application est essentiel pour assurer que ces infrastructures gasifiantes soient non seulement conformes aux exigences techniques, mais également adaptées aux conditions environnementales avec une température de fonctionnement allant de -20 °C à +40 °C. L'une des forces majeures de cette norme réside dans son approche exhaustive, qui couvre trois types de tuyaux en PE : les tuyaux en PE avec des bandes d'identification, ceux présentant des couches co-extrudées, et ceux dotés d'une couche supplémentaire de thermoplastique peelable. Cette diversité permet une grande flexibilité dans l'application et le choix des matériaux, garantissant ainsi une adaptation aux besoins spécifiques de l'infrastructure gazière. De plus, la norme EN 12007-2:2012 souligne l'importance d'intégrer les exigences de la norme EN 12007-1, établissant un cadre solide de principes de base pour l'infrastructure gazière. Il est crucial de noter que bien que cette norme européenne offre une direction claire, elle n’opère pas en vase clos et indique que des normes nationales plus détaillées peuvent exister. Cette synergie assure que les utilisateurs soient bien informés des législations et régulations en vigueur dans leur pays, garantissant ainsi la conformité avec toute exigence nationale plus stricte. En outre, son alinéa sur la prépondérance de la législation nationale en cas de conflit souligne la pertinence de cette norme dans le contexte de la régulation locale. Ce point est essentiel pour les acteurs du secteur, car il leur permet de naviguer efficacement dans le paysage complexe des réglementations tout en répondant aux spécificités de l'application des pipelines en PE. En conclusion, la norme EN 12007-2:2012 se révèle être un document fondamental pour toute entreprise impliquée dans l'infrastructure gazière, assurant que les exigences fonctionnelles sont respectées tout en tenant compte des divers égards réglementaires nationaux. Sa formalisation des exigences fonctionnelles spécifiques pour les pipelines en polyéthylène ajoute une valeur significative à la sécurité et à l'efficacité des systèmes gaziers.
The EN 12007-2:2012 standard provides a comprehensive framework for the specific functional requirements of polyethylene (PE) pipelines intended for gas infrastructure with a maximum operating pressure (MOP) up to and including 10 bar. Its well-defined scope includes detailed specifications for operating temperatures ranging from -20 °C to +40 °C, ensuring optimal performance and safety within these conditions. One of the notable strengths of this standard is its coverage of three distinct types of PE pipes, which enhances its applicability across various gas transportation scenarios. The inclusion of PE pipes with identification stripes, co-extruded layers, and peelable thermoplastics additional layers ensures that the standard addresses diverse technical requirements and enhances the versatility of PE pipelines in gas infrastructure projects. Furthermore, the standard emphasizes the importance of integration with pre-existing national standards and codes of practice, promoting a harmonized approach to gas pipeline design and installation across CEN member countries. This collaborative aspect ensures that while EN 12007-2:2012 provides a robust baseline, stakeholders are encouraged to adhere to potentially more restrictive national regulations, prioritizing local legislative requirements where applicable. The relevance of EN 12007-2:2012 cannot be understated in the context of safety and efficiency in gas infrastructure. By specifying common basic principles, the standard aids manufacturers, engineers, and regulatory bodies in understanding and implementing the essential safety measures necessary for reliable gas transport. Additionally, its alignment with the guidelines set forth in FprCEN/TR 13737-1 offers clarity in navigating national legislations, further enhancing its applicability and effectiveness.
