I. Introduction flow duct endoscopy Endoscopy Endoscopy container flow impeller view mirror view mirror
Endoscopy is one of the main accessory of industrial pipes means it can always observe the pipeline by the gas, liquids and other media flow reactor, monitoring of the production, the production process to avoid accidents. Often used in petroleum, chemicals, chemical, pharmaceutical and other industry production pipelines. maximum operating medium temperature 0 ~ 200 ℃ maximum working pressure is 2.5Mpa, tempered glass resistant CML temperature difference of 180 ℃.
Second, depending on the purpose and structure of the mirror
Purpose: Mirrors can be used in high temperature, corrosive, easy to poisoning, more dangerous, easily crystallized chemical tower in order to ensure its safety in production.
Structure: endoscopic mainly by the toughened borosilicate glass, flange, take over the other components.
Third, the technical parameters
Carbon steel, stainless steel, steel lined
Toughened borosilicate glass, quartz glass
0 ℃~180℃, 0℃~300℃
(0.6Mpa, 0.6Mpa ~ 2.5Mpa
Nitrile rubber, Teflon
Threaded connection, flange connection
Abrupt changes in temperature allowed
0.6Mpa ~ 2.5Mpa
HG20592-09 (also according to user requirements)
Manufacturing, testing standards: reference (chemical pipeline manual) and HG / T21619 ~ 21610-1986 (pressure vessel view mirror) design and manufacturing and acceptance.
Fourth, the selection:
According to shape into ordinary endoscopy and endoscopy with neck etc. pipeline flow Mirrors Mirrors Mirrors container flow impeller view mirror view mirror
Use according divided into straight endoscopy, through reducers mirrors, float mirrors, swing plate mirrors, glass sight glass and the like.
Selection must provide: nominal diameter, material, pressure rating, flanges standard operating temperature.
