Glass-Lined Tanks

Glass-Lined Steel Equipment Customization

These glass-lined tanks are engineered for superior corrosion resistance, combining premium metallic substrates (such as ASTM A516 Gr.70 carbon steel or stainless steel) with high-performance PEMCO enamel. Fully compliant with ASME VIII Div.1 and PED 2014/68/EU standards, they are the ideal solution for storing corrosive media including inorganic acids, organic acids, and organic solvents across chemical, pharmaceutical, food, and fine chemical industries.

Structure and Materials

Metal Substrate
Carbon steel or stainless steel is used as the base material to provide the structural strength and stability required for safe storage operation.
Enamel Lining
Using Q245R steel plate and high-temperature treatment at 820°C-930°C, the tank forms an inorganic inert lining with a thickness of ≥0.2 mm. This lining offers strong resistance to acids and alkalis (pH 1-14), excellent corrosion resistance, and high adhesion strength of 3450 N/cm.

Features

Capacity Range
Vertical Glass-Lined Tanks are available in capacities of up to 100000L, while horizontal designs are suitable for capacities from 1000L to 80000L.
Working Conditions
Typical operating temperature ranges from -20°C to 200°C, with a working pressure of ≤2.5 kg/cm².
Inspection Standard
The enamel lining is tested with a 20 kV high-voltage spark test to ensure that the coating is free from defects.

Why Us

Certified manufacturing standards
We hold authoritative ASME (Section VIII Division 1) and CE (PED) certifications, ensuring full compliance with international safety and quality standards. This guarantees our glass-lined steel equipment meets the strict regulatory requirements of global chemical, pharmaceutical, and agrochemical clients.
In-House Enamel R&D Laboratory
Our dedicated in-house R&D center specializes in custom enamel formulations, including acid-resistant, acid-alkali resistant, high-temperature resistant, and wear resistant options. These proprietary formulas deliver exceptional durability against corrosive media, mechanical impact, and thermal shock, ensuring reliable performance in diverse operating environments.
Precision Belt Polishing Pretreatment
Prior to enameling, every steel shell undergoes rigorous precision belt polishing to thoroughly remove mill scale, pits, and surface impurities. This meticulous pretreatment process ensures superior substrate smoothness and integrity, providing an ideal, contamination-free foundation for strong and uniform enamel bonding.
Advanced Cold Spray Enameling Process
Our glass-lined equipment utilizes advanced cold spray enameling process with multiple high-temperature firing cycles. This technology ensures a thinner, more uniform, and denser enamel layer with significantly reduced risk of chipping or peeling. The controlled firing process guarantees optimal adhesion and long-term durability in the most demanding chemical processing conditions.

Multi-zone electric furnace control
The enameling furnace uses independent multi-zone control with computerized management of heating, holding, and cooling. The temperature difference inside the furnace is controlled within 5°C, helping maintain consistent firing quality.
Vertical firing process
All equipment is produced using a vertical firing process, which provides more even heating, reduces deformation, and helps maintain the overall appearance of the equipment as well as flange flatness.
Controlled slow firing curve
The firing process follows a low-temperature entry and low-temperature exit slow-firing curve. Combined with dedicated furnace tooling and controlled firing methods, this helps ensure enamel quality comparable to that of established international manufacturers.
Full-process quality management
We maintain a complete quality management system with full-process control. For glass-lined quality inspection, we apply three inspection procedures covering:
1. internal and external visible defects
2. enamel thickness
3. high-voltage spark testing
This helps ensure that delivered products meet required standards and specifications.
Custom non-standard equipment design and manufacturing
Custom design and manufacturing support is available for non-standard products. Based on different process requirements, tailored solutions can be developed for special equipment structures and agitator selection supported by CFD fluid dynamics simulation.
Strong R&D capability
We have strong research and development capacity and currently hold more than 40 national patents covering equipment tooling, products, and manufacturing processes.
