What Is a Plate Flange? A Practical Guide
Plate flanges are fabricated by cutting profiles from flat carbon or stainless steel ASTM specified plate. Subsequently, they are machined to precise specifications, including bolt hole patterns and center bores. While forged flanges are shaped under high pressure or force from round or square billets, plate flanges are cut from flat stock (commonly ASTM A36 […]
DIN Flange Pressure Ratings: EN 1092-1 Overview
DIN flange pressure ratings are defined through the PN system (e.g., PN10, PN16, PN25) and standardized under EN 1092-1. The standard specifies flange dimensions, bolt patterns, and rating principles for metric piping applications. This article explains the DN/PN designation structure, clarifies how PN relates to pressure capability, and compares the practical differences between PN10, PN16, […]
What’s the Difference Between DIN and ASME / ANSI Flanges
DIN and ANSI / ASME flanges are governed by two completely different standards systems which are used in piping, mechanical, and industrial engineering. While both of them define flange dimensions, pressure ratings, materials, and tolerances, they are still built on different measurement systems, regional practices, and design methodologies. DIN flanges are metric-based and primarily used […]
DIN Flange Dimensions and Specifications
Deutsches Institut für Normung (DIN) is one of the standards organizations that complies with European and International standards. DIN sets industry guidelines for quality assurance and safety, including flange materials requirements and pressure and temperature rating. DIN flanges are widely used in metric piping systems across Europe and in international industrial projects. While the term […]

How to Order Pipe Flanges
When ordering pipe flanges and parts, it’s best to be as specific as possible. Include details such as: 1: Size Nominal Pipe Size (NPS) The nominal pipe size of the connecting pipe is defined by the flange size (NPS). The NPS does not always correspond to the flange inside diameter. B16.5 is for .5″-24″ NPS flanges, and […]
