Borosilicate Glass Tube

by TianPeter

Tubular borosilicate glass can be used in tanks, boilers, reservoirs, flow reading equipment and much more. The borosilicate glass construction makes the tubular high pressure glass durable enough to hold up to high pressure, high temperatures and even corrosive chemicals.
