WINDOW ON PRESSURE PIPE Russian patent published in 2012 - IPC B01J3/00 B29C35/06 

FIELD: machine building.

SUBSTANCE: window on pressure pipe includes housing located throughout the length of the pipe or at the end of pressure pipe. Diametrically opposite sides of the pipe are provided with flanges with passages oriented in radial direction. Axes of passages are perpendicular to longitudinal axis of pressure pipe and lie in the measuring plane of X-ray measuring device. X-ray emission source is located outside one passage, and receiver sensitive to X-ray emission is located outside the other passage. Window arranged on pressure pipe includes window plates permeable for X-ray emission and installed tightly in the corresponding passage and fixed in the passage by means of fasteners. Window plates consist of the material resistant to high temperatures and action of corrosive chemical process substances. The design at least of lower window plate and target maintenance of uniform temperature of window plate are made so that temperature of window plate is maintained below condensation point of gas medium in pressure pipe, and condensate can freely flow to pressure pipe.

EFFECT: reduction of corrosion of window plate and increase in its service life.
