Technical specifications and purpose of DIN 2561 flanges
The DIN 2561 standard defines the engineering requirements for oval threaded flanges equipped with a hub. These products are designed for operation in pipeline systems with a nominal pressure of 10 bar (PN 10) and 16 bar (PN 16) with nominal diameters ranging from DN 6 to DN 40. EV Group China products meet the strict requirements for geometry and operational reliability set by specialized committees for boiler and pipeline equipment standardization.
Materials and manufacturing standards
To ensure durability and corrosion resistance in various industrial environments, EV Group China offers flanges manufactured from the following steel groups:
- Stainless steel grades (high resistance to aggressive environments);
- Carbon steel grades (optimal balance of strength and cost);
- Alloy steel grades (for operation under high-load conditions).
Placing an order for manufacturing according to DIN 2561
To ensure precision in the production and supply of metal products, when placing an order with EV Group China, it is necessary to specify the following technical parameters:
- Size type and design configuration of the flange;
- Geometry and profile of the sealing surface;
- Exact overall dimensions and required tolerances;
- Type and parameters of the threaded connection;
- Specifications of fasteners (bolt size);
- Requirements for the cleanliness and condition of the sealing surfaces;
- Steel grade and calculated weight of the product.
