Wholesale High Borosilicate Glass Pipe/ customized glass pipe factory price

Glass Pipe Series

Glass Pipe is used in most laboratory and industrial applications where the drainage system sees a wide variety of chemicals. In many applications it may be the only material that will hold up to the acids that will be flowing through the system. In applications where high heat or fire is a concern, glass pipe is almost always the material of choice. Glass pipe is available in 5 or 10 foot sections up to 12” in diameter.

Acid and alkali resistance
The acid and alkali resistance is high, especially quartz, which do not react with any acid except hydroflouric acid. The stability of glass is 30 times of ceramic and 150 times of stainless steel.
Tight dimensional tolerance
The dimension is accurate and the tolerance is tight. What's more, we can customize according to your requirement.
Low coefficient of thermal expansion
Our glass tubes have low coefficient of thermal expansion. The softening point can reach 1500 °C, so that the glass tube can withstand temperature as high as 1200 °C.
Precise boring
As for our precision glass tube, the tolerance can be as small as 0.005 mm.
Excellent outlook
Our glass tube are clear, bright and polishing. We can also color it as your requirement.
