Fused Quartz Glass Tubes With Flanges
Quartz tubes can be welded together to tightly connect flanges. After annealing treatment, the strength of quartz glass is increased. Our quartz glass tubes with flanges have high dimensional accuracy and can be assembled well with other parts. High temperature resistance, corrosion resistance, and excellent product performance.Mechanical Properties
