Weld-End Inline Pipe Sight Glass
See inside your process line with the Borlan Fluid weld-end inline pipe sight glass. The transparent cylindrical viewing section, weld-end connections and external tie rods are shown in the product images. Reference sizes span 19-102 mm; confirm materials, duty conditions and an approved drawing for your application.
The Borlan Fluid Weld-End Inline Pipe Sight Glass provides a clear view into a process line. Its transparent cylindrical viewing section sits between two weld-end connections, while external tie rods secure the end assemblies. The open view from several directions helps operators check flow presence and visible process conditions at the installed inspection point.
Designed for visual checks in a welded pipeline
When a pipe run needs a direct viewing point, this inline sight glass brings the process into view through a cylindrical window. The photographs show its opposing weld ends, clear viewing section, bolted end assemblies and external rods. Borlan Fluid can review the connection dimensions and assembly details against your project drawing before you place an order.
