SGC40 / SGS40 Sight Glass
The SGC40 in carbon steel and the SGS40 in stainless steel are sight glasses with double glass and threaded, socket weld, sanitary clamp, or flange connections.
Standards:
These products fully comply with the European Pressure Equipment Directive and bear the CE marking when required.
Certificates:
These products are available at an additional cost with a Type Test Report or material certificate according to EN 10204 3.1. Certificates are only provided upon request at the time of ordering.
Options:- Vane to make the flow of the liquid in the pipeline clearly visible.
- Spring spring-loaded vane for installation in vertical pipelines or at high flow rates.
- Mica glass protectors for challenging applications. Nomenclature with Mica glass protectors: SGC40M and SGS40M.
Use Mica glass protectors for the following applications:
- Application: Steam or pH > 9, use glass: Mica glass protectors and glasses in borosilicate.
- Application: > 150C and pH > 7, use glass: 7 Mica glass protectors and glasses in borosilicate.
- Application: < 150c="" and="">< ph,="" use="" glass:="" glasses="" in="">

Threaded connections: BSP, NPT, and Socket weld.
DN15, 20, 25, 40, and 50
Sanitary clamp connections according to ASME BPE. DN15, 20, 25, 32, 40, 50, 65, 80, and 100
Flanges EN 1092 PN25, ASME 150 and 300, JIS/KS 10 and JIS/KS 20.
The flanged versions have flange-to-flange distances in accordance with EN 558 Series 1.
Installation:
Always install a valve before and after the sight glass. Close the valve in front of the sight glass first to prevent overpressure. Install the sight glass downstream of the condensate pot, in both horizontal and vertical pipelines, with the flow direction indicated by the arrow on the housing. Always install sight glasses with a vane (option) with the hinge point upwards to achieve correct operation. For condensate pots with intermittent condensate discharge, such as the thermodynamic or inverted bucket condensate pot, place this sight glass at least 1m downstream of the condensate pots to prevent erosion or breakage of the glass due to thermal shocks or pressure surges. Also, take the necessary measures to prevent injury to personnel or bystanders in the event of possible glass breakage. Always install it in a sufficiently accessible manner for maintenance.
