DIPTI METAL INDUSTRIES
Dipti Metal Industries is a Leading global EN 1092-1 Flange Manufacturer, EN 1092-1 PN 6 Flanges Supplier & EN 1092-1 PN 6 Flanges Exporter of low-pressure flanges conforming to the European Standard **EN 1092-1** in the **PN 6** pressure rating (0.6 MPa / ~87 PSI). This class is widely used for general low-pressure piping systems, including water lines, ventilation, and industrial liquid transport, covering a vast size range from **DN10 up to DN4000**. We supply all compatible flange types (Type 01 Plate, Type 05 Blind, Type 11 Weld Neck, etc.) and ensure material traceability and dimensional compliance for seamless integration into European and global piping networks. Materials are sourced from the **EN 10222** forging standard, ensuring certified quality.
Founded in 2009 in Mumbai, India, we are a global EN 1092-1 Flange Manufacturer and PN 6 Flange Exporter specializing in low-to-high pressure flanges for international markets. Our manufacturing process guarantees that our PN 6 flanges adhere strictly to the dimensions, facing, and tolerances specified in the EN 1092-1 standard. We focus on efficiently supplying projects requiring large quantities of low-pressure flanges, particularly in the oversized diameters (DN1400-DN4000) often seen in utility and heavy industrial installations. All our forgings are procured and certified to the comprehensive EN 10222 material specification.
The EN 1092-1 standard is the primary specification for circular steel flanges for piping in Europe. PN 6 (Nominal Pressure 6 Bar) is a low pressure rating, often used in large-bore pipe systems and non-critical industrial applications where cost and size are factors. The standard specifies dimensions, bolt configuration, and material requirements to ensure interoperability across European pipe systems.

UNIT: mm. Data extracted from EN 1092-1 Table 11, focusing on the PN 6 Mating Dimensions (D, K, L, N, Size).
Dimensions apply across all Type 01/02/05/11/21 flanges for PN 6.
We manufacture all the primary flange types mandated by EN 1092-1 in the PN 6 pressure class, utilizing certified EN 10222 forging grades to ensure full interoperability for low-pressure European systems.
The PN 6 class is generally used for large-volume, low-head applications where cost and size reduction are balanced against a modest pressure requirement.
As a global EN 1092-1 Flange Exporter and Supplier, Dipti Metal Industries efficiently services European and international projects requiring large volumes of PN 6 flanges for utility and low-pressure installations.
Contact Dipti Metal Industries today for certified EN 1092-1 PN 6 Flanges of all types (01, 05, 11, etc.). Provide your required Flange Type, Nominal Size (DN), and Material (e.g., S235JR or 1.4404) for a competitive, customized quote and expert technical support.
