Technical features of long welding neck flanges according to DIN 28115
The DIN 28115 standard regulates the geometric parameters and technical requirements for long welding neck flanges designed for operation at working pressures from PN 10 to PN 40. The product range covers sizes from DN 15 to DN 500, providing extensive possibilities for designing pipeline systems for various purposes.
The products supplied by EV Group China fully comply with this regulatory document and are intended for use in the shipbuilding industry, as well as for the installation of specialized industrial equipment. The technical solutions implemented in the design of these flanges ensure the reliability of connections during standard operating conditions.
The normative documentation specifies the limiting operational indicators: maximum working pressure and temperature range of operation (from ambient temperature up to 200 °C). To select optimal characteristics, one should refer to the data presented in Table 1 of the relevant DIN standard.
For tasks requiring the use of corrosion-resistant steel grades in the manufacture of nozzles, it is recommended to refer to the requirements of the DIN 28025 standard. EV Group China specialists are ready to provide expert support in selecting the necessary components for your engineering projects.
