Unlined Stainless Steel Sight Glass

The stainless steel tubular sight glasses CRP manufacture are designed to offer the highest levels of process viewing with a clear Borosilicate Glass tube offering 360 degree viewing. The glass is of a heavy wall construction up to 9mm thick and depending on nominal bore the sight glasses can be used in processes up to 10 barg and 150 degrees C.

The flange ends are manufactured from stainless steel and can be supplied to suit ASME 150 or DIN PN10 and PN16.

We can also supply the flange ends in other materials such as Hastelloy, Supler Duplex etc.

We would recommend that all our sight glasses are supplied with an outer acrylic shield to help prevent mechanical damage of the glass from external elements.

We offer a standard length of sight glass equivalent to the Atomac AKH2 valve in length. We call this our CTSG Tubular Sight Glass. We can supply all sizes of sight glasses in shorter or longer lengths up to 1500mm, we call these with a special length DTSG Tubular Sight Glasses.

Dimensions below are for the standard CTSG Tubular Sight Glass available to suit both ASME 150 and DIN PN10/16 flanges to EN558-1 basic series 1.
