Inline Sight Glass

Operating Instructions

22

6.3 Installation 

Note

The inline sight glass is installed in accordance with the structural layout of the 

pipeline system and the technical data for the connection variants.

See the dimensional drawings for the installation dimensions. Ensure suffi cient 

space is available for operation and maintenance.

Make sure that the fl ange connections and pipe unions are leak-proof. Tensile 

and compression stresses shall be ruled out after installation.

6.3.1 Installing the Inline Sight Glass with Male/Male, Liner/Liner, Male/Liner

When installing the inline sight glass, ensure that the connectors and slotted nut conform to the same 

standard (e.g. DIN 11851 or DIN 11864).

Before assembly, check the seal ring on the threaded connector for damage and to ensure that it is 

installed in the correct position. Replace if necessary.

The thread must not be damaged when installing!

The inline sight glass is fastened using the slotted nut and a slotted nut spanner.

6.3.2 Installing the Inline Sight Glass with Weldon Ends

Welding guidelines

Welding shall be carried out in pipes conforming to DIN 11850 series 2, DIN 11866 series A and C, 

SMS standard (France)

Welding method: 

TIG or orbital welding

Seam type: 

 

butt weld joins as per DIN EN 29692

Installed condition

The inline sight glass must be uninstalled before welding (see section on assembly / disassembly).

Weld seam preparation

- Cut the ends of the pipes level and right-angled.

- Remove burrs from the interfaces. 

- Align the housing weldon ends with the pipeline so they are level radially and axially.

  The weldon ends must fi t fl ush and be welded without a gap.

HAZARD

“HAZARD”

 Make sure that the sight glass can be installed and removed undam-

aged, without breakage, cracks or dents, and without tension or stress. A dam-

aged sight glass may break causing serious injuries and damage to property. 

Tensile and compression stresses shall be ruled out after installation.
