They comply with strict international standards such as DIN 7080, JIS B8286, and ASME, making them suitable for use in various global industrial applications.Our sight glasses feature a precision-engineered design that provides a wide field of view for clear process observation. The oblong oval shape offers a balanced combination of structural strength and optimal visibility. Additionally, we offer customized solutions to meet specific user requirements, including different sizes, materials, and sealing options, ensuring a perfect fit for your unique application.Oblong Oval Sight Glass Product Performance? Application:Ideal for viewing the insides of pipes, vessels, containers, reactors,silos, etc., and used primarily as a liquid level indicator for monitoring e. g. filling levels.? Operating conditions:- Pressure 2.5/6/10/25 bar- Vacuum- Prior to using the fitting, the cut-out reinforcement togetherwith the relevant material of the vessel should be checked inaccordance with AD-Merkblatt.? Operating temperature:100°C when using soda-lime glass to DIN 8903 (on request only)243°C when using borosilicate glass to DIN 7081? Certification/Approval:Testing and certification can be provided to DIN EN 10204 3.1/3.2as required by the customer (at extra charge).We can customize according to customer needs.Parts & materials: (The drawing is below)ItemComponentmaterial1Connecting flangeStainless steel 1.4404 or other gradeson request (Steel S235JR+N (RST 37-2)2GasketsKLINGERSil C-4400; Neoprene;PTFE or others3Sight glass plate- Soda-lime glass: thermallyprestressed to DIN 8903,max. operating temperature: 100°C- Borosilicate glass: thermallyprestressed to DIN 7081,max. operating temperature: 243°C4Cover frameStainless steel 1.4404 or other gradeson request (Steel S235JR+N (RST 37-2))5Fastening boltsSteel 8.8 or stainless steel A4Installation:Prior to fitting the glass plate, check to ensure that the base frame(1) is free of any distortion and the sealing surface is flat.Any tension or unevenness can lead to leakage or may even cause the sight glass to break.After the base frame has been welded into or onto the pipe orvessel wall, the gaskets (2), the sight glass plate (3) and the cover flange (4) are positioned in the order illustrated and then fastened to the base frame (1) with the bolts (5).When securing the cover flange, the bolts should be tightened with a uniform torque, starting with the bolts in the middle and working crosswise towards the ends, i.e. in an alternating sequence.Lumistar Special Glass Technology Co., Ltd. is a professional enterprise that produces safety glass windows and water level gauge glass windows.
