Is 90 Million Yuan Energy Saving in 10 Years for 1km 400℃ Steam Pipeline with Aerogel True? Real Data Revealed!

How to choose insulation for high-temperature pipelines?

Aerogel vs Aluminum Silicate Wool

We clarify all the facts about performance, heat loss and economic benefits.

1. Actual Working Conditions & Accurate Calculation

• Pipeline: DN300, Length 1km

• Temperature: 400℃ high-temperature steam

• Energy price: 110 RMB/GJ

• Comparison: Aerogel insulation blanket / Traditional aluminum silicate wool

2. Key Data at a Glance

A. Performance Difference

• Aerogel:

Thermal conductivity at 400℃: 0.03～0.04 W/(m·K)

Thermal insulation efficiency: 2~3 times that of aluminum silicate wool

• Aluminum Silicate Wool:

Thermal conductivity at 400℃: 0.08～0.10 W/(m·K)

Large heat loss, easy to sag and pulverize

B. Real Energy-Saving Benefits

• Annual energy saved: 7560 GJ

• Annual economic benefit: 831,600 RMB

• Total benefit in 10 years: 8,316,000 RMB

✅ Truth:

1km pipeline saves about 8.3 million RMB in 10 years.

The claim of “90 million” is seriously exaggerated.

3   Long-Term Performance: Which Is More Reliable?

Advantages of Aerogel

• Better insulation, lower heat loss

• No sagging or pulverization, stable for 10 years

• Hydrophobic & anti-corrosion

• Thinner thickness, saves space

• Lower life-cycle cost

Characteristics of Aluminum Silicate Wool

• Lower upfront cost

• Easy to compress at high temperature, heat loss increases year by year

• Requires regular maintenance and replacement

4   Conclusion & Suggestion

1) For 400℃ high-temperature steam pipelines, aerogel brings significant benefits, saving about 8.3 million RMB in 10 years.

2) For long-term, high-temperature and energy-saving renovation projects, aerogel is preferred.

3) For temporary, low-temperature or low-cost projects, aluminum silicate wool can be chosen.

Choose materials rationally and don’t be misled by exaggerated claims.

Real energy saving depends on data and long-term performance.

Reject marketing gimmicks, only tell engineering truths. 

This real aerogel comparison report is worth collecting and sharing for every engineering manager and procurement specialist!
