borosilicate glass disc for sight glass
The borosilicate glass disc for sight glass supplied by Link glass co.,ltd is a transparent observation window made from high‑purity borosilicate material. It is offered in thicknesses ranging from 5 mm to 60 mm, providing the thermal resistance required for tanks, reactors and pressure vessels. The disc delivers optical transmittance above 90 % in the visible spectrum, allowing clear monitoring of fluid levels under industrial conditions.
Borosilicate glass is valued for its low coefficient of thermal expansion and resistance to thermal shock, typically tolerating temperature differentials up to 300 °C. In the chemical, pharmaceutical and food‑processing sectors the material is standard for sight‑glass applications because it does not leach contaminants and maintains structural integrity under cyclic heating. The discs can be cut to custom diameters and are supplied in protective packaging to prevent edge damage during transport.
Industrial buyers such as process plant engineers, equipment integrators and maintenance contractors commonly source these discs for retrofit or new‑build projects. Link glass co.,ltd states that minimum order quantities are flexible and that shipping can be arranged on FOB or CIF terms. Prospective purchasers should request a detailed drawing and confirm the required thickness, diameter and any special coating before placing an order.

Sourcing borosilicate glass disc for sight glass from Link glass co.,ltd - Hong Kong Import Guide
Before ordering, verify the exact disc dimensions, thickness tolerance and pressure‑test certification. Request a technical data sheet that lists the coefficient of thermal expansion and the approved temperature range for the intended application. Confirm that the supplier can provide a mill‑test report for the batch you will receive.
Logistics for Hong Kong‑based suppliers usually involve FOB or CIF terms. Ask the supplier to state the expected lead time, preferred Incoterms and acceptable payment methods such as T/T or LC. Because the response rate is currently 0 %, allow extra time for communication and confirm shipping details in writing.
Arrange a third‑party inspection at the point of loading to check for surface defects, thickness uniformity and dimensional accuracy. Request the original mill test certificate, a compliance statement to ISO 1043 and any additional quality‑assurance documentation before final payment.
