Mengenai sambungan flensa pada sistem perpipaan, standar internasional memastikan konsistensi, keamanan, dan kompatibilitas. One of the most widely used European flange standards is EN 1092. This standard defines the dimensions, toleransi, peringkat tekanan, and surface finishes for a variety of flange types used in industrial pipelines across the EU and other regions.

Dalam artikel ini, kami akan menjelaskan 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 sasa lonjong, 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, baja tahan karat, aluminum, and copper alloys. The standard is applicable to flanges used in pipa, katup, perlengkapan, dan bejana tekan, 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.

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

Why EN 1092 Matters

Dalam sistem perpipaan industri, flange compatibility is critical. If the flanges are mismatched in dimensions or pressure ratings, the risk of leaks, kegagalan, and safety issues increases significantly.

By following EN 1092, manufacturers and engineers ensure:

• Interchangeability of parts across European and global projects

• Reliable sealing dibawah tekanan

• Standardized design, reducing engineering errors

• Compliance with EU regulations for pressure equipment

EN 1092 is widely adopted in industries such as minyak & gas, pengolahan air, pemrosesan kimia, pembuatan kapal, Dan obat-obatan.

Types of Flanges in EN 1092

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

• Jenis 01: Plate flange

• Jenis 02: Loose plate flange with weld-on plate collar

• Jenis 05: Flensa buta

• Jenis 11: Flensa leher las

• Jenis 12: Hubbed slip-on flange

• Jenis 13: Flensa berulir

• Jenis 21: Integral flange

Each type serves a specific function in the pipeline, and the choice depends on factors such as tekanan, jenis cairan, metode koneksi, Dan kisaran suhu.

Pressure Ratings in EN 1092

EN 1092 flanges are available in several kelas tekanan, often referred to as PN (Nominal Tekanan):

• hal 6

• hal 10

• hal 16

• hal 25

• hal 40

• hal 63 / 100 / 160 / 250 / 400 (for higher pressure systems)

Itu PN rating indicates the maximum allowable pressure at a reference temperature. Misalnya, 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. sasa lonjong provides technical support to help customers select the right flange based on application needs.

Dimensions and Surface Finishes

EN 1092 specifies detailed flange ukuran, termasuk:

• Diameter luar

• Diameter lingkaran baut

• Number and size of bolt holes

• Ketebalan flensa

• Menaikkan tinggi wajah

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

• Wajah Terangkat (Federasi Rusia)

• Wajah Datar (FF)

• Lidah dan Alur (T&G)

• Pria dan Wanita (M&F)

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

Semua sasa lonjong 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:

• Manufacturer identification

• EN 1092 penamaan

• Kelas tekanan (hal)

• Kelas materi

• Nomor panas atau kode batch

Hal ini memastikan full traceability and compliance with the European Pressure Equipment Directive (PED) and other industrial requirements.

sasa lonjong menyediakan EN 10204 3.1 atau 3.2 inspection certificates upon request, offering peace of mind to buyers and inspectors.

EN 1092 vs. 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

• gost standards in Russia

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

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

Applications of EN 1092 Flensa

EN 1092 flanges are used in various systems, seperti:

• Water supply and sewage

• Pabrik pengolahan bahan kimia

• Heating and cooling pipelines

• Sistem proteksi kebakaran

• Pharmaceutical and food-grade systems

Their standardization ensures aman, tahan bocor, and reliable connections in both low- and high-pressure environments.
