borosilicate glass tube manufacturer

Providing you with top quality borosilicate glass tubes

Shenxun is a professional manufacturer of high-end borosilicate glass tubes. We provide high-quality products that meet ISO 3585 international standards to customers around the world. Our borosilicate glass tubes have unique physical and chemical properties:

Low thermal expansion coefficient (3.3×10^-6/K) ensures structural stability under extreme temperature differences from -60℃ to 500℃.

With a fracture toughness index of 17.5 MPa·m^1/2, the impact resistance is more than 5 times that of ordinary glass.
The thickness of glass tubes we can make（Wall thickness）:1mm, 1.5mm, 2.0mm, 2.2mm, 2.3mm, 3mm, 4mm, 5mm, 6mm. 
The longest tube size: 2m

Our advantages:

1. Laboratory-grade pipes are FDA certified. They are suitable for vaccine storage ampoules in pharmaceutical companies’ GMP cleanrooms, observation windows of precision analytical instruments and other key scenarios;
2. The industrial special series includes full-specification pipelines from DN15 to DN600, meeting the requirements of harsh working conditions such as semiconductor etching equipment reaction chambers and solar thermal power generation collection systems;
3. The fire-resistant hollow glass curtain wall components launched by the Building Innovation Section have passed the EN 13501-1 fire protection certification, with a thermal deformation temperature of 820°C. They have been successfully applied to the safety systems of super-high-rise buildings such as the Dubai Torch Tower.
