Jul. 31, 2025

*How to Avoid Costly Rework and Safety Risks*

Industrial insulation failures can lead to energy leaks, safety hazards, and project delays. Based on global field data from petrochemical, power, and LNG projects, Huali Insulation reveals the most critical installation pitfalls and proven solutions to maximize project efficiency.

1. The 5 Most Common Industrial Insulation Failures & Fixes

Problem 1: Material Delamination/Peeling

- Causes : Poor adhesive selection, surface contamination, thermal cycling

- Huali Solution :

✅ Use HT-800 High-Temp Epoxy Adhesive (resists 800°C)

✅ Surface prep protocol: Sandblast + Huali Primer 101

Problem 2: Moisture Ingress & Corrosion

- Risk : Insulation corrosion under piping (CUI)

- Huali Solution :

✅ Hydrophobic Rock Wool Blankets (98% water repellency)

✅ Double-layer facing material with aluminum foil

Problem 3: Thermal Bridging at Joints

- Impact : 15-30% heat loss at pipe supports/valves

- Huali Solution :

✅ Custom Molded Sections for complex geometries

✅ Aerogel Gap Fillers for ≤1mm precision sealing

Problem 4: Vibration-Induced Cracking

- High-Risk Sites : Compressors, pump stations

- Huali Solution :

✅ Vibration-Resistant Rock Wool Mats (30% higher tensile strength)

✅ Compression-limiting design for bolt stress points

Problem 5: Fireproofing Failures

- Compliance Risk : Non-A1 materials in refineries

- Huali Solution :

✅ Fireproof Rock Wool System (EN 13501 Class A1)

✅ Pre-certified for ASTM E84

2. Case Study: Fixing Insulation Failures at Saudi LNG Plant

- Project : Cryogenic piping (-196°C) insulation upgrade

- Original Issues : Moisture ingress → ice buildup, valve failures

- Huali Intervention :

1. Replaced fiberglass with Rock Wool Blankets

2. Installed laser-cut vapor barriers at all joints

- Results :

✅ Zero CUI incidents in 18 months

✅ 35% lower energy loss vs. previous system
