360° Flow Sight Glass with Weld-neck flanges DIN/ANSI

Article number: D1512

Description:

Direct installation by welding the flanges into an existing pipeline. No separate housing required.
An installation aid is supplied to facilitate installation.

Advantages:

  • High pressure ratings

  • 360° full circumferential view of the medium

  • Dead-space free and low maintenance

Our sight glasses are available in various metal grades, tailored to the respective field of application:

1.4404 (AISI 316L): Corrosion-resistant, ideal for hygienic and chemical applications

1.4571 (AISI 316Ti): Particularly resistant to high temperatures and acids – suitable for aggressive media

P265GH: Pressure Equipment Directive (PED) compliant boiler steel for applications in energy and heat engineering

 

 

The following glass materials are available for the viewing section:

Tempered borosilicate glass: Standard material for pressure, temperature, and chemical exposure (DIN 7080)

Untempered borosilicate glass: Suitable for particularly high temperatures up to 450 °C (e.g., laboratory and special applications)

Quartz glass: High-temperature and UV-resistant – ideal for extreme thermal or optical requirements

Polycarbonate: Impact-resistant, lightweight, suitable for low-pressure applications and visual inspection without aggressive media
