Weld neck flange, DN 150, PN 16, pipe 168.3 mm, DIN 2633 and EN 1092-1 (type 11), 1.4571

Once installed, the weld neck flange carries the welded pipe run and creates a bolted joint that can be opened again. The data also state a nominal pressure of PN 16. The stated figure is a nominal size of DN 150. In addition the data give the version to DIN 2633 and EN 1092-1 (type 11) and 8 bolt holes.

Benefits

• Nominal size DN 150 at a nominal pressure of PN 16 to DIN 2633 and EN 1092-1 (type 11).
• Welding end of 168.3 mm outside diameter and 4.5 mm wall thickness.
• Flange outside diameter 285 mm on a bolt circle of 240 mm.
• 8 bolt holes of 22 mm diameter.
• Overall height 55 mm with a formed hub for the transition to the pipe.
• Material 1.4571 for the choice by medium and surroundings.

Applications

In plant that is opened often the DN 150 joint gives access to the line without touching the weld.

Standards and conformity

Dimensions and design follow DIN 2633 and EN 1092-1 (type 11) at a nominal pressure of PN 16.
