EN이란 무엇입니까? 1092 플랜지 표준?

When it comes to flange connections in piping systems, international standards ensure consistency, 안전, and compatibility. One of the most widely used European flange standards is EN 1092. This standard defines the dimensions, 공차, 압력 등급, and surface finishes for a variety of flange types used in industrial pipelines across the EU and other regions.

이 기사에서는, 우리는 설명할 것이다 what the EN 1092 flange standard is, what types of flanges it includes, and why it is essential in today’s engineering and manufacturing industries. Provided by SASAFLANGE, your professional supplier of high-quality flanges that comply with global standards.

What Is EN 1092?

EN 1092 is a European Standard that specifies the requirements for circular flanges made from various materials, including steel, 스테인레스 스틸, aluminum, and copper alloys. The standard is applicable to flanges used in 파이프, 밸브, 피팅, 및 압력 용기, primarily in industrial systems that carry liquids and gases.

The full name of the standard is EN 1092-1, which focuses specifically on steel flanges. It was developed by the European Committee for Standardization (CEN) to harmonize flange specifications across Europe.

SASAFLANGE provides EN 1092-compliant products with precise manufacturing and full traceability for international projects.

Why EN 1092 Matters

산업용 배관 시스템, flange compatibility is critical. If the flanges are mismatched in dimensions or pressure ratings, the risk of leaks, failures, and safety issues increases significantly.

By following EN 1092, manufacturers and engineers ensure:

Interchangeability of parts across European and global projects
Reliable sealing 압력을 받고 있는
Standardized design, reducing engineering errors
Compliance with EU regulations for pressure equipment

EN 1092 is widely adopted in industries such as 기름 & 가스, 수처리, 화학 처리, 조선, 그리고 의약품.

Types of Flanges in EN 1092

EN 1092-1 includes several flange types, commonly identified by a short code:

유형 01: 플레이트 플랜지
유형 02: Loose plate flange with weld-on plate collar
유형 05: 블라인드 플랜지
유형 11: 웰드 넥 플랜지
유형 12: Hubbed slip-on flange
유형 13: 스레드 플랜지
유형 21: Integral flange

Each type serves a specific function in the pipeline, and the choice depends on factors such as 압력, 유체 유형, 연결 방법, 그리고 온도 범위.

SASAFLANGE offers all standard EN 1092 플랜지 유형, customizable in various pressure classes and materials.

Pressure Ratings in EN 1092

EN 1092 flanges are available in several 압력 등급, often referred to as PN (압력 공칭):

PN 6
PN 10
PN 16
PN 25
PN 40
PN 63 / 100 / 160 / 250 / 400 (for higher pressure systems)

그만큼 PN rating indicates the maximum allowable pressure at a reference temperature. 예를 들어, a PN 16 flange is rated for 16 bar pressure at 20°C.

Choosing the correct PN class is crucial for system safety and efficiency. SASAFLANGE provides technical support to help customers select the right flange based on application needs.

Dimensions and Surface Finishes

EN 1092 specifies detailed flange 치수, 포함:

외경
Bolt circle diameter
Number and size of bolt holes
플랜지 두께
얼굴 높이를 높였습니다.

The standard also defines surface finish requirements to ensure a proper gasket seal. The sealing face can be:

제기된 얼굴 (RF)
편평한 얼굴 (FF)
혀와 그루브 (티&G)
Male and Female (중&에프)

A typical finish for a raised face flange under EN 1092 는 serrated concentric or spiral groove, providing effective gasket grip and sealing performance.

모두 SASAFLANGE products adhere to strict surface finish tolerances as per EN 1092 to guarantee leak-free operation.

Marking and Certification

Flanges under EN 1092 must be clearly marked with essential data such as:

제조업체 식별
EN 1092 지정
압력 등급 (PN)
재료 등급
Heat number or batch code

This ensures full traceability and compliance with the European Pressure Equipment Directive (소아과) and other industrial requirements.

SASAFLANGE 제공하다 EN 10204 3.1 또는 3.2 inspection certificates upon request, offering peace of mind to buyers and inspectors.

EN 1092 대. Other Standards

EN 1092 is the European counterpart to standards like:

ASME B16.5 in the United States
BS 4504 (now mostly replaced by EN 1092 in the UK)
JIS B2220 in Japan
고스트 standards in Russia

While similar in function, these standards differ in dimensions, 공차, and bolt patterns. When exporting or importing equipment, compatibility between standards must be verified.

As a globally focused manufacturer, SASAFLANGE offers flanges that meet EN, ASME, and other international norms, helping you bridge global supply chains.

Applications of EN 1092 플랜지

EN 1092 flanges are used in various systems, ~와 같은:

Water supply and sewage
화학 처리 공장
Heating and cooling pipelines
화재 예방 시스템
Pharmaceutical and food-grade systems

Their standardization ensures 안전한, 누출 방지, and reliable connections in both low- and high-pressure environments.

결론

그만큼 EN 1092 플랜지 표준 plays a critical role in ensuring safety, 능률, and compatibility in industrial pipeline systems across Europe and beyond. From weld neck to blind flanges, and from PN 6 to PN 400 평가, this standard provides a clear framework for manufacturers, 엔지니어, and end users.
