Flanges
Flange Solutions Meeting European Standards
Flanges conforming to EN and DIN standards are widely used in piping systems designed according to European norms.
These flanges, available in various types and pressure classes, have a wide range of applications and provide secure connections in industrial facilities and infrastructure projects.
Flat (Plate) Flanges (Type 01)
EN 1092-1 Type 01 / DIN 2573, 2576
An economical and commonly used flange type for low-pressure systems.
Weld Neck Flanges (Type 11)
EN 1092-1 Type 11 / DIN 2631 – 2635
A durable flange type used in lines requiring high strength.
Blind Flanges (Type 05)
EN 1092-1 Type 05 / DIN 2527
Used to securely close the ends of pipelines.
Free (Rotating) Flanges (Type 02 / 04)
EN 1092-1 Type 02 & 04 / DIN 2641, 2642
Offers alignment advantages with a rotating structure that facilitates assembly.
Threaded Flanges (Type 13)
EN 1092-1 Type 13 / DIN 2565, 2566
A practical connection solution for systems that do not require welding.
Loose Flanges
Provides flexible usage options with aluminum or steel collar models.
EN / DIN FLANGE PRESSURE CLASSES
These are the pressure classes selected according to the application area of the flanges.
• PN 6 / PN 10 → Low pressure systems
• PN 16 → The most common piping group
• PN 25 / PN 40 → Medium and high pressure applications
• PN 63 / PN 100 / PN 160 → Heavy duty and industrial lines
