Advanced Storage Tank Linings & Industrial Tank Coatings
Engineered for extreme immersion and high-temperature resistance. Protect your critical assets against chemical attacks with our heavy-duty epoxy tank lining and solvent-free systems.
Industrial Tank Integrity: Strategic Corrosion Mitigation & Chemical Containment
Storage tank assets represent a critical investment in industrial infrastructure, yet they operate under constant duress. Internal surfaces are subject to aggressive chemical attack and permeation from stored media—including crude oil, sour gas, and high-purity chemicals—while external shells battle localized atmospheric corrosion and UV-driven degradation.
Our engineering approach prioritizes long-term asset lifecycle over short-term fixes. We specialize in the application of 100% solids, solvent-free glass flake epoxy linings that meet and exceed API 652 standards for bottom protection. This technology creates a dense, impenetrable shield that resists the diffusion of corrosive ions, even in high-temperature immersion services.
Beyond the primary vessel, our solutions extend to secondary containment and environmental compliance. By integrating advanced lining technology with edge-retentive coatings, we minimize the Total Cost of Ownership (TCO) and ensure zero-leak operations, safeguarding both your operational continuity and the surrounding ecosystem.
Why Storage Tank Protection Fails
Standard coatings often fail under extreme petrochemical environments, leading to catastrophic leaks and unplanned shutdowns.
Internal Chemical Attack
Crude oil and aggressive chemicals cause rapid pitting in chemical storage tank linings. A single localized failure can lead to environmental disasters and massive fines.
CUI & Thermal Cycling
Hidden CUI corrosion under insulation destroys tank shells silently. Temperature fluctuations cause standard coatings to crack, exposing steel to moisture.
Excessive Maintenance Cost
Short-lived coatings increase tank maintenance costs. Every day of unplanned downtime for re-coating costs hundreds of thousands in lost production.

System: Zinc + Epoxy + PolysiloxaneStorage Tank Coating FAQ
Our NACE-certified engineers answer the most common technical questions regarding tank lining performance and application.
01. What is the standard for internal tank lining conductivity?
For refined oil and chemical storage, HUILI anti-static linings maintain a surface resistance between 10^5 to 10^8 Ω, strictly complying with API 652 to prevent electrostatic discharge (ESD) hazards.
02. Can your Novolac Epoxy system withstand 98% Sulfuric Acid?
Our HUILI-900 series glass flake epoxy is specifically engineered for secondary containment and internal lining of strong acid tanks. It provides an exceptional chemical barrier against 98% H2SO4 at ambient temperatures.
03. What are the surface preparation requirements for C5 environments?
To ensure maximum adhesion, we require abrasive blasting to Sa 2.5 (ISO 8501-1) with a medium roughness profile (G) of 75-100 microns. The first coat must be applied within 4 hours of blasting to prevent flash rust.
04. How long is the curing time before the tank can return to service?
At 25°C, the lining is touch-dry in 4 hours and hard-dry in 24 hours. However, for full chemical immersion service, a full cure of 7 days is required to ensure cross-linking integrity.
