Product description

MAXOS® Round Borosilicate Safety Sight Glass DIN 7080



MAXOS® Borosilicate Safety Sight Glasses according to DIN 7080 are essential where visual inspection of processes in tanks is required under pressure, in thermal and chemical conditions. The high safety of the round DIN 7080 sight glasses is achieved through special borosilicate glass with good chemical resistance, extraordinary purity, and homogeneity. Combined with the low thermal expansion typical of this borosilicate glass, thermal preloading (hardening) results in particularly high resistance to temperature changes.


Our work is characterized by a pronounced awareness of quality and quality management. For all MAXOS® Safety Sight Glasses according to DIN 7080, we provide, upon customer request, inspection certificates 3.1 according to EN 10204. Certificates 2.2 or pressure tests are also possible. Additionally, we can offer food safety statements, conformity with FDA standards, as well as IHK certificates of origin or individual manufacturer statements.

MAXOS® Round Borosilicate Safety Sight Glass DIN 7080


Application of MAXOS® Borosilicate Glass:

MAXOS® borosilicate safety sight glasses are used where processes in tanks and pipelines need to be visually inspected under pressure, and/or under thermal and chemical loads. The high safety level is achieved through special borosilicate glass with good chemical resistance, exceptional purity, and homogeneity. In connection with the low thermal expansion typical of this borosilicate glass, thermal preloading (hardening) results in particularly high resistance to temperature changes.

The sight glasses according to DIN 7080 are suitable for installation in standard round sight glasses according to DIN 28120/DIN 218121 or similar, and also for use in screwed sight glasses according to DIN 11851 (so-called "sanitary," "milk coupling," or "dairy" version).

The glasses with central bore have the same application as above but can be equipped with a wiper.

These sight glasses are hardened by thermal treatment, polished, and the edges ground.

Options for borosilicate glass according to DIN 7080:

  • Individual pressure tests
  • Special dimensions
  • Double or composite glazing with discs of similar or different diameters.
  • Certificates according to DIN EN 10204 can be provided at an additional cost


 

Technical Details of Borosilicate Glass

Temperature:  Continuous load max. 280 °C, brief periods up to 300 °C, with mica protective shield max. 320 °C, no lower temperature limit.

The properties of the glasses and the close size tolerances are guaranteed by production and quality controls in the manufacturing process. With these excellent safety properties, MAXOS® safety glass can be used for extreme conditions.

It is especially these safety aspects that make technicians prefer MAXOS®.

Chemical Resistance:

  • Water resistance according to DIN ISO 719/720 hydrolysis class 1
  • Acid resistance according to DIN 12116 - acid class 1
  • Alkali resistance according to DIN 52332 - alkali class 2


 

Material:

 Borosilicate glass hardened according to DIN7080

Shape

Round glass according to DIN 7080

Nominal Size:

 Diameters: Ø 24 mm to 265 mm, other sizes are available on request.

Nominal Pressure:

The nominal pressure of the borosilicate glass depends on the dimensions; see datasheet.


Whenever a sight glass is disassembled, it is strongly recommended according to DIN 7080 that the glass disc and gaskets be replaced with new ones.
This is especially important for pressure vessels and/or aggressive media.

The following excerpt from the text of DIN 7080 is literal:'Sight glasses may only be installed by personnel who are fully informed:

  • Handle the sight glasses with care
  • Clean openings, glass, gaskets, and other parts i.e. removal of foreign objects (e.g., chips), prior to installation/remounting
  • Tighten fastening bolts with the proper torque

The used borosilicate glass may not be reused after use.


Planned Maintenance of Sight Glasses:

Sight glasses should be included in routine maintenance and should be periodically visually inspected or using ultrasonic wall thickness measurement. In case of damage, the sight glass must be exchanged immediately after the process has been shut down.

The maintenance period of the sight glass, depending on the pressure vessel in which it is mounted and the application, must be regularly inspected

Note: Fully demineralized water can dissolve glass, requiring particularly intensive periodic inspection!

Breakage of a sight glass:
Despite careful installation and recommended use, sight glasses can, in rare cases, crack due to external influences. To prevent glass from entering critical products, such as food, appropriate safety measures should be taken by the manufacturer or user.
