What Are Type 01 Flanges?

In the EN 1092-1 standard system, Type 01 flanges—also called plate flanges or welded flat flanges—are a basic flat face flange design where the flange is essentially a flat plate with a bore and bolt circle, welded (or otherwise joined) to the pipe. The sealing face is in the same plane as the bolting face (flat face), commonly used when mating flanges or cast components have flat faces.

Introduction to EN 1092-1 Standard

The production of this shipment of SS316 PN16 Type 01 Flanges is strictly governed by the EN 1092-1 standard. This European standard, widely recognized and adopted globally, specifies requirements for circular steel flanges from DN 10 to DN 4000. This standard also dictates the material groups, pressure designations (like PN16), and testing methods, providing a foundational assurance of quality, safety, and interchangeability for our clients.
