AIX Glass Lined Tower Section | Factory Direct | Standard Enamel Tower Segment for Distillation/Absorption Tower

Glass Lined Tower Section (also known as Enamel Tower Segment) is the core standard section of tower equipment (distillation tower, absorption tower, reaction tower, scrubber) in chemical, pharmaceutical and environmental protection industries. Its core structure is carbon steel matrix pressure bearing + high silicon enamel layer anti-corrosion. Using high-quality low-carbon steel as the cylinder, the inner wall is sprayed with high-corrosion-resistant glass enamel for many times and sintered at high temperature (860-920℃) in sections, so that the enamel is tightly fused with the metal matrix to form a dense, smooth and corrosion-resistant glass protective layer. Designed and manufactured in strict compliance with the latest industry standard HG/T 3127-2024 "Glass Lined Tower Sections" and TSG 21 special equipment specifications, it has excellent corrosion resistance, thermal stability and structural strength, and is a standardized and modular core component for constructing various corrosion-resistant tower equipment.

1. Product Structure & Working Principle

The glass lined tower section is a vertical cylindrical standard segment with necked flanges at both ends (Type A for clamp connection / Type B for bolt connection), facilitating multi-stage series assembly. During operation, the metal cylinder bears system pressure and mechanical load, while the inner glass lined layer provides strong anti-corrosion, anti-adhesion and easy-cleaning properties, realizing process such as distillation separation, absorption purification and reaction mass transfer of corrosive gas-liquid media. The enamel layer has extremely strong chemical stability with surface roughness Ra≤0.5μm, no scaling, no adhesion and low fluid resistance, ensuring high efficiency and long-term stable operation of gas-liquid contact in the tower.

3. Core Performance Advantages

1. Super Corrosion Resistance for Harsh Media

High-silicon enamel layer resists corrosion of most inorganic acids, organic acids, salts and organic solvents, suitable for media with pH 1-12 (except hydrofluoric acid, concentrated phosphoric acid >180℃, high-temperature & high-concentration strong alkalis). Corrosion resistance superior to 304/316 stainless steel, no media pollution, no metal ion precipitation, in line with pharmaceutical and food GMP clean standards.

2. Standard Modular, Flexible & Efficient Assembly

Manufactured strictly in accordance with HG/T 3127-2024 standard, unified dimensions and strong interchangeability. Can be freely combined in series according to process requirements to quickly build distillation, absorption and reaction towers of different heights and capacities, shortening equipment manufacturing and installation cycles.

3. Excellent Thermal Stability & Thermal Shock Resistance

Long-term stable operating temperature -20℃~200℃, resistant to rapid cooling and heating (heat shock 120℃ / cold shock 110℃). Enamel layer cracking avoided with reasonable temperature rise/fall rate, adapting to frequent temperature fluctuation conditions, stability far exceeds plastic and plastic-lined tower sections.

4. Ultra-Smooth Surface, High Mass Transfer Efficiency

Inner glass lined layer is extremely smooth, no scaling, no adhesion, no material residue. Effectively reduces gas-liquid resistance, improves mass transfer and separation efficiency in the tower, reduces blockage risk, lowers cleaning and maintenance frequency and cost.

5. Sturdy Structure, Long Service Life

Low-carbon steel matrix + dense enamel layer composite structure, reliable pressure bearing and strong anti-deformation capacity. Strong bonding between enamel layer and matrix, service life up to 10-15 years under normal use, longer with proper maintenance.

6. Factory Customization, Global Condition Adaptation

Support non-standard customization (diameter, length, flange type, jacket structure). Provide international certifications such as CE, ISO, adapt to global flange standards (ANSI/DIN/HG), meet different working conditions at home and abroad.

4. Manufacturing Process & Quality Control

AIX glass lined tower sections adopt standardized lean manufacturing:
1. Matrix: High-quality low-carbon steel coiled and welded, sandblasted to Sa2.5 grade for clean and rough surface.
2. Enameling: Precision cold spraying process, multiple uniform spraying of ground coat and cover coat, precise thickness control.
3. Sintering: Sectional high-temperature firing (860-920℃), furnace temperature uniformity ≤±5℃, ensuring strong adhesion of enamel layer without defects.
4. Inspection: Each section undergoes hydrostatic test, air tightness test and 20kV spark test before delivery to ensure no pinholes, cracks or leaks.

5. Application Scenarios

Widely used in corrosion-resistant tower equipment in chemical, pharmaceutical, fine chemical and environmental protection industries:

• Chemical Distillation: Purification of corrosive materials such as organic acids, chlorides and esters

• Solvent Recovery: Distillation and recovery of ethanol, acetone, dichloromethane and other organic solvents

• Exhaust Gas Absorption: Purification and absorption towers for acidic waste gases (HCl, SO₂, NOx)

• Chemical Reaction: Reaction towers for corrosive media such as chlorination, sulfonation and oxidation

• Environmental Treatment: Wastewater evaporation, exhaust gas scrubbing, desulfurization and denitrification towers

6. Executive Standards & Certifications

• Industry Standard: HG/T 3127-2024 "Glass Lined Tower Sections"

• Specification Standard: TSG 21, GB/T 7989{insert\_element\_1\_}

• International Certifications: CE, ISO9001, FDA (Available on Request)

7. Installation & Usage Notes

1. Installation: Handle with care, prohibit knocking or collision on enamel layer; use special corrosion-resistant gaskets for flange seals, tighten bolts evenly.
2. Temperature: Control heating/cooling rate ≤1-2℃/min, strictly prohibit rapid cooling or heating.
3. Media: Prohibit contact with hydrofluoric acid, high temperature (>180℃) concentrated phosphoric acid, high temperature & high concentration strong alkalis (pH>12, >80℃).
4. Maintenance: Forbid metal tools to clean inner wall; conduct spark test regularly (6-12 months).
5. Operation: Strictly prohibit overpressure, overtemperature and overload operation.
