Product Description

Clear Round Borosilicate glass 3.3 Sight Glass Level Gauge withsize 30mm*30mm

 

For compressive stress with temperatures borosilicate circular sight glass up to max. 280 degrees Celsius,
Where a greater degree of chemical resistance or higher operating temperatures are required, a borosilicate glass should be specified. In a toughened form, temperatures up to 315 degrees Celsius are possible whilst annealed glass may be used up 400degrees Celsius continuously with a short term maximum of 500 degrees Celsius.
In addition to standard DIN sizes, glasses are available in a wide range of diameters up to 60mm thick (see annular edge sight glass).

Soda Lime glass according to DIN 8902.
For compressive stress with temperatures borosilicate circular sight glass up to max. 150 degrees Celsius,
This is the most commonly used material due to its low cost. It can be easily toughened to effectively increase the mechanical strength of annealed glass by up to five times. 
We have plant and equipment, including our water-jet cutting machine and CNC machining center, to produce diameters between 3mm and 1500 mm, and thicknesses up to 25m.

Quartz glass according to customer's requirements, made from JGS1, JGS2, JGS3, on production.

Testing ItemStandard Rules
1. Appearance

1) Air bubble:
Diameter≤0.5mm,in the 10mm x 10mm area the quantity must be ≤3.
Diameter from 0.5mm to 1.5mm dispersive air bubble,there is less 2 on the sight plane and less 5 on the No-sight plane. Their distance must be 40mm.
The air bubble of Diameter from 1.5mm to 2mm ≤3  on the No-sight plane. Their distance must 40mm.
On the sight plane, The distance to the side in 7.5mm,the air bubble of the  diameter1mm mustnt be more 2.
2) The glass dont allow slag and scrap iron,etc. impurity.
3) Stripe : dont allow have palpable filaceous and pectinate stripe on the sight plane.
4) Cockle: In the side face,dont allow have the cockle of depth 1mm.
5) Crack: dont allow have crack.
6) Scrape: On the sight plane and in the 7.5mm to edge,the scrape of less than 10mm dont allow more 2 strips.
7) The sight plane must be polishing,and sealing side must be rubbing and polishing.

3. Water-resistanceCooked in the water for 5 hours,then weigh up ,then titration with 25ml    0~31    ug/g
4. Alkali-resistanceCooked in the 0.5N NaoH for 3 hours,then Weigh up,weightlessness should be ≤75  mg/dm2
5. Temperature-resistance impacts capabilityPut it into electric cooker,keep for 7min under the temperature of 260±1,then,put into the water of 20±1,it should not crack
6. Bend-resistance≥80 MPa
