Twopressure vesselsight glassPurpose of Preparationsight glassAs a peeping device for pressure vessels, it has been widely used in industries such as petroleum, chemical, pharmaceutical, and light industry. With the continuous improvement of technical level in design, materials, manufacturing and other aspects of China's pressure vessel industry this year, and the gradual development of the standard system, both design standards and material standards have been updated accordingly. And our current

sight glassDue to its early publication, some content in the standard can no longer be coordinated with other current standards.Meanwhile, considering several current factorssight glassThe series, specifications, dimensions, etc. in the standard are also inconsistent, making it inconvenient for designers to choose. In order to adapt to the current situation of the standard system and the needs of practical engineering, according to the plan and arrangement of the National Boiler and Pressure Vessel Standardization Technical Committee, the Fixed Container Branch of the National Boiler and Pressure Vessel Standardization Committee is responsible for organizing it. China Petrochemical Engineering Construction Company is currentlypressure vesselsight glassOn the basis of the standard, this standard has been formulated.In response to recent reasonspressure vesselsight glassAccidents caused by quality reasons, in order to standardizepressure vesselsight glassMarket, guaranteesight glassThe National Boiler and Pressure Vessel Standardization Technical Committee plans to approve the product qualitysight glassRevision of standards, forpressure vessel
