Glass Piping in Process Industry


All-glass piping is used for its chemical resistance, cleanliness and transparency. Glass pipe is not subject to ‘crazing’ often found in glass-lined pipe and vessels subject to repeated thermal stresses. Pipe, fittings, and hardware are available both for process piping and for drainage.

Corning Glass Works offers a Pyrex ‘Conical’ system for process lines in 1, 1 1/2, 3, 4 and 6-inch sizes (10) with 450 F as the maximum operating temperature, and pressure ranges 0-65 PSIA (1 in. thru 3 in.), 0-50 PSIA (4 in.) and 0-35 PSIA (6 in.). Glass cocks, strainers and thermowells are available. Pipe fittings and equipment are joined by flange assemblies which bear on the thickened conical ends of pipe lengths and fittings.

Corning also offers a Pyrex Acid-Waste Drainline system in 11/2, 2, 3, 4 and 6-inch sizes (10) with beaded ends joined by Teflon-gasketed nylon compression couplings.

Beth Corning systems are made from the same borosilicate glass.
