Glass-Lined Tank

Aix Boiler is the OEM factory of glass-lined tanks, featuring high-quality steel body with high-borosilicate glass lining, acid & alkali resistant and thermal shock resistant, complying with GB/T 25025 & GB/T 7994, suitable for corrosive media storage in chemical, pharmaceutical, food industries, supporting full customization of volume, caliber and wall thickness.

Aix Boiler glass-lined storage tank operates based on the core principles of high-temperature sintering combination of steel substrate and high-borosilicate glass lining, physical isolation of corrosive media, and dual guarantee of structural pressure bearing and chemical stability. The equipment uses high-quality carbon steel or low-alloy steel as the base material, lined with high-borosilicate glass glaze on the inner wall, and sintered at 900℃ to form a dense and seamless corrosion-resistant barrier, realizing long-term safe storage of corrosive media such as acid, alkali and salt, with excellent thermal shock resistance (-20℃~200℃). Designed and manufactured in accordance with pressure vessel standards, the whole structure includes tank body, heads, manhole, inlet & outlet, liquid level meter port, support, ladder and platform, featuring stable pressure bearing, corrosion resistance, easy cleaning, no leakage and long service life. This product is strictly produced in compliance with GB/T 25025-2025 Technical Specifications for Glass-Lined Equipment and GB/T 7994 Test Methods for Glass-Lined Equipment, passing four quality controls: hydrostatic test, air tightness test, mechanical impact test and glaze thickness test, with 100% factory pass rate. As an own-brand product of Aix Boiler OEM factory, we independently complete R&D, cutting, sintering, assembly and testing in the whole process with no middleman price difference, supporting full customization of volume 5m³~200m³, caliber, wall thickness and insulation layer. It is widely used in corrosive media storage in chemical, pharmaceutical, food, environmental protection, new energy and other industries, serving as core equipment for corrosion-resistant storage in modern industry.
