Overview
EN 1092-1 Type 01 Plate Flange is a flat plate–type flange manufactured in accordance with EN 1092-1 European standard. It is produced from steel plate by cutting and machining, with accurately drilled bolt holes and a machined sealing surface.
This flange type is widely used in water supply, fire protection, HVAC, and general industrial piping systems, especially for low to medium pressure applications where cost efficiency and standard compatibility are required.
Product Description
EN 1092-1 Type 01 Plate Flanges are designed to provide a reliable flanged connection for pipes, valves, pumps, and fittings. The flange is welded directly to the pipe end or used as a loose backing flange in certain applications.
Type 01 refers specifically to the plate flange without a hub, making it a simple and economical solution compared with forged or neck-type flanges.

FAQ
Type 01 refers to a plate flange without a hub, manufactured from steel plate. It is the simplest flange type defined in EN 1092-1.
Yes. Many former DIN flange standards (such as DIN 2573, DIN 2501) have been harmonized into EN 1092-1. In practice, EN 1092-1 Type 01 is the modern equivalent of traditional DIN plate flanges.
For most waterworks and fire protection systems:
PN10 and PN16 are the most common
For industrial applications:
PN25 and PN40 may be required
Type 01: Plate flange, no hub
Type 02: Slip-on flange with hub (SO)
Type 02 offers easier alignment and slightly higher mechanical strength, while Type 01 is more economical.
FF (Flat Face) – commonly used for ductile iron valves and water systems
RF (Raised Face) – used in steel piping systems with specific gasket designs
The facing type should be selected according to gasket and system requirements.
