The High-Silicon Glass-Lined Steel Piping is a composite pipeline formed by lining a steel pipe with silicate glass, thereby creating a steel-bonded-to-glass structure.<\/p>\n
Glass-Lined Steel Piping feature high chemical stability, smooth inner walls, wear resistance, negative pressure tolerance, and high\/low temperature resistance (-30\u00b0C ~ 300\u00b0C). Widely used in chemical, petrochemical, pharmaceutical, and food industries. DN25-DN500 full specifications available.<\/p>\n
