4inch Jacketed Sight Glass, For Chemical Fertilizer Pipe

A 4-inch Jacketed Sight Glass is a specialized flow visualization device designed for applications requiring temperature control or thermal insulation of the fluid being observed. Featuring a double-layer construction with an outer jacket, it allows heating or cooling media (such as steam or water) to circulate around the sight glass, maintaining the process fluid at a desired temperature. Key Features Size: • Nominal diameter: 4" (DN100) • Suitable for medium to large process lines and tanks Construction: • Body made from stainless steel (304/316), carbon steel, or alloy steel • Viewing window made from thick borosilicate or tempered glass for high pressure and thermal shock resistance • Double-wall (jacketed) design with inlet and outlet ports for heating or cooling media circulation • Sealed with high-performance gaskets such as PTFE, Viton, or graphite Design: • Full-view tubular glass for 360° visibility • Jacket allows temperature control to prevent freezing, condensation, or overheating of process fluid • Flanged or welded ends for secure installation in pipelines or vessels Operating Conditions: • Temperature range: up to 250°C (depending on materials and jacket media) • Pressure rating: typically up to 10 bar, customizable for higher ratings Applications Chemical reactors requiring temperature control Food and beverage processing with heating or cooling needs Pharmaceutical and biotech process vessels Oil and gas pipelines with temperature-sensitive fluids Water treatment systems requiring freeze protection Benefits Temperature Control – Maintain process fluid temperature for optimal reaction or flow conditions Enhanced Visibility – Full-view design enables thorough visual monitoring Durability – Robust materials and construction for demanding industrial environments Versatility – Compatible with various heating/cooling media and customizable to your process needs If you want, I can provide a technical datasheet, detailed drawings, or a quote tailored to your exact specifications and application. 4.1-mini
