Sight Glass Material can be supplied and processed as Glass Plate when the exact grade or functional material duty, stock form, dimensions, thickness, edge and surface requirements are defined by the drawing. The assigned material or application record notes: Borosilicate combines transparency, heat resistance and chemical durability, but the grade and heat-treatment state must match the armature and medium. The assigned product record adds: Rectangular plate, cover plate, stepped plate, grooved plate, base plate or machined panel.

Drawing-defined feasibility
Final feasibility is reviewed against grade, supplied stock, dimensions, thickness, holes, cutouts, edges, surfaces, quantity and inspection criteria.
How the Glass Type and Product Form Fit Together
The assigned technical records separate published material or application guidance from the dimensions and acceptance criteria that remain drawing-specific.

|---|---|
| Material definition | Sight Glass Material describes a function rather than one universal composition. State the actual glass grade or operating temperature, pressure, chemical, optical or sealing duty in the RFQ. |
| Product-form definition | Rectangular plate, cover plate, stepped plate, grooved plate, base plate or machined panel |
| Typical materials | BOROFLOAT 33, soda-lime float, low-iron, fused silica, glass-ceramic or aluminosilicate |
| Application duty | Provide continuous visual observation across a vessel, tank or pipe pressure boundary without losing containment. |
| Inspection basis | Length/width/thickness inspection, flatness map, edge microscopy, hole location check and cosmetic transmission inspection |
The Actual Glass Grade Must Be Named in the RFQ

Industrial Sight Glass
Provide continuous visual observation across a vessel, tank or pipe pressure boundary without losing containment.
Geometry, Surface and Inspection Requirements
Product-family data is a planning reference. The drawing must identify the exact shape, critical zones and measurable acceptance limits.
| Product requirement | What to define |
|---|---|
| Geometry and available forms | Rectangular plate, cover plate, stepped plate, grooved plate, base plate or machined panel |
| Dimensions and thickness | Up to 2,286 × 1,701 mm published BOROFLOAT stock reference; finished CNC envelope may be smaller |
| Holes, cutouts and features | Dimension holes, slots, cutouts, steps, grooves, radii and their edge distances. |
| Edge and surface zones | Seamed for handling, ground for fit, polished for exposed edges, chamfered for assembly |
| Inspection | Length/width/thickness inspection, flatness map, edge microscopy, hole location check and cosmetic transmission inspection |
| Packaging and handling | State cleanliness, protective film, separators, individual packing and shipping requirements. |
| Manufacturing route item | Review requirement |
|---|---|
| Supplied stock | State sheet, plate, tube, rod, disc, wafer, blank or preform condition. |
| Compatible route | Sheet cutting, waterjet or CNC profiling, edge grinding/polishing, surface grinding, drilling and optional strengthening |
| High-risk geometry | Thermal shock, gasket point loading, wrong pressure derating, chemical surface attack and edge-initiated fracture. |
| Drawing release | For Sight Glass Material Glass Plate, define datums, critical features, edge and surface zones, quantity, inspection and packaging before releasing the route. |
Inspection Focus for Custom Sight Glass Material Glass Plate Processing
Acceptance should connect every critical drawing characteristic to an instrument, fixture condition and stated limit.
| Review item | Project-specific focus |
|---|---|
| Product design risk | Large-area bow, thermal gradient, unsupported span, corner stress and damage at cutouts |
| Product inspection | Length/width/thickness inspection, flatness map, edge microscopy, hole location check and cosmetic transmission inspection |
| Application failure modes | Thermal shock, gasket point loading, wrong pressure derating, chemical surface attack and edge-initiated fracture. |
| Application inspection | Dimensions, edge microscopy, transmitted-light inspection, certificate review, then assembly leak/pressure validation. |
| Acceptance method | Transmittance Measurement: Compare calibrated result with the drawing, purchase order or approved test specification |
| Feature-to-edge damage | For Custom Sight Glass Material Glass Plate Processing, inspect chips, microcracks, breakouts and edge damage around processed features and adjacent walls. |
