Glass-Lined Steel Pipes
Glass-lined steel pipes are composite pipes constructed with a metal substrate (typically carbon steel or stainless steel) coated on both inner and outer surfaces with a dense vitreous enamel layer through high-temperature sintering. The core manufacturing process involves evenly spraying borosilicate glass or enamel frit onto the metal surface, followed by firing at 900-960°C to form a 0.8-1.5mm thick corrosion-resistant layer, combining the mechanical strength of metal with the chemical stability of glass.
Exceptional Corrosion Resistance
Withstands inorganic acids (sulfuric, hydrochloric, nitric acids), organic acids, solvents, and weak alkalis
Not suitable for hydrofluoricacid, strong alkalis (pH ≥12), or high-temperature phosphoric acid
Superior Physical Properties
Ultra-smooth surface (micron-level finish) minimizes media adhesion
Compressive strength: 0.6-1.0 MPa
Thermal stability: -20°C to 200°C operating range
Hygienic & Safe
Glass layer prevents metal ion leaching, meeting food/pharmaceutical cleanliness standards
Electrostatically shielded
Widely used in:
-Chemical processing (45% market share)
-Pharmaceutical manufacturing
-Food & beverage production
-Environmental engineering
Ideal for:
Corrosive fluid transfer
High-temperature reaction systems
Sanitary-grade fluid handling
