Weld neck flange, DN 25, PN 40, pipe 33.7 mm, DIN 2635 and EN 1092-1 (type 11), black steel

In use, the weld neck flange carries the welded pipe run and creates a bolted joint that can be opened again. It is produced from black steel. The data give a pipe outside diameter of 33.7 mm and a flange outside diameter of 115 mm. In addition the data give the version to DIN 2635 and EN 1092-1 (type 11) and 4 bolt holes.

Benefits

• Nominal size DN 25 at a nominal pressure of PN 40 to DIN 2635 and EN 1092-1 (type 11).
• Welding end of 33.7 mm outside diameter and 2.6 mm wall thickness.
• Flange outside diameter 115 mm on a bolt circle of 85 mm.
• 4 bolt holes of 14 mm diameter.
• Overall height 40 mm with a formed hub for the transition to the pipe.
• Material black steel for the choice by medium and surroundings.

Applications

In plant that is opened often the DN 25 joint gives access to the line without touching the weld.

Standards and conformity

Dimensions and design follow DIN 2635 and EN 1092-1 (type 11) at a nominal pressure of PN 40.
