2. The importance of thermal insulation of petrochemical pipelines
2.1 Necessity of pipeline insulation
The medium conveyed by petrochemical pipelines usually has high temperature and high pressure characteristics. Pipeline insulation can effectively reduce heat loss, reduce energy consumption, and improve production efficiency. In addition, insulation can prevent condensation on the surface of the pipe, reduce the risk of corrosion, and extend the service life of the pipe.
2.2 Limitations of traditional insulation materials
Although traditional insulation materials such as glass wool, rock wool, etc. have certain insulation effects, they have the following problems:
- High thermal conductivity: Limited thermal insulation effect.
- Complex construction: requires multiple layers of wrapping, and the construction period is long.
- Poor environmental protection: Some materials contain harmful substances and are not environmentally friendly.
2.3 Advantages of new insulation materials
New insulation materials such as polyurethane foam have the advantages of low thermal conductivity, simple construction, and environmental protection. The application of low viscosity odorless amine catalyst Z-130 further improves the performance of polyurethane foam and makes it more competitive in petrochemical pipeline insulation.
III. Application principle of low viscosity odorless amine catalyst Z-130 in pipeline insulation
3.1 The formation process of polyurethane foam
The formation of polyurethane foam mainly goes through the following steps:
- Mix: Mix the raw materials such as polyols, isocyanates, catalysts, foaming agents, etc. in proportion.
- Foaming: The catalyst promotes reaction, generates carbon dioxide gas, and forms a foam structure.
- Currect: The foam structure gradually cures to form a stable insulation layer.
3.2 Catalytic action of Z-130
Z-130, as a catalyst, can significantly accelerate the reaction between polyol and isocyanate, shorten the foaming time, and improve the uniformity and stability of the foam. Its low viscosity characteristics make the mixing more uniform, while its odorless properties improve the construction environment.
3.3 Energy-saving effect analysis
The application of Z-130 further reduces the thermal conductivity of polyurethane foam and significantly improves the thermal insulation effect. At the same time, its efficient catalytic effect reduces energy consumption in the production process and reduces production costs.

4.2.2 Case 2: A new pipeline built in oil refinery
- Background: A new pipeline construction in a certain refinery requires efficient insulation materials, which require environmental protection and simplified construction.
- Solution: Use polyurethane foam insulation material and add Z-130 catalyst.
- Effect: The construction cycle is shortened by 30%, the insulation effect is significant, and it meets environmental protection requirements.
4.3 Economic Benefit Analysis

|---|---|---|
| Material Cost | Lower | Higher |
| Construction Cost | Higher | Lower |
| Energy consumption | Higher | Lower |
| Service life | Short | Length |
| Comprehensive Cost | Higher | Lower |
It can be seen from the table that although the material cost of Z-130 catalytic polyurethane foam is relatively high, its construction cost is low, energy consumption is low, and its service life is long, and its overall cost is lower than that of traditional insulation materials.
