Introduction
1. Scope and applicability of the standard
GB/T 4272—2024 specifies the overall requirements, material performance requirements, insulation design, insulation structure, construction and acceptance of equipment and pipeline insulation projects, and is applicable to equipment and pipelines with an external surface temperature of -196 ℃ ~ 850 ℃.
2. Background of Standardization and Technological Evolution
| Version | Main changes | Scope of application |
|---|---|---|
| GB 4272—1984 | First release of insulation technical standard | Basic insulation requirements, no specific performance indicators |
| GB/T 4272—2008 | Added fire protection and antifreeze requirements | Applicable to industrial equipment and pipelines |
| GB/T 4272—2024 | New requirements on thermal conductivity of aerogel insulation products and performance of gaskets | Expanded to multiple temperature ranges, with new special requirements such as fire prevention and antifreeze |
3. Implementation suggestions
- Material selection:Preferably use insulation materials with low thermal conductivity, low density and reasonable economy, such as aerogel products and high-density polyisocyanurate.
- Construction specifications:Construction must be carried out in strict accordance with GB 50126 to ensure the integrity and durability of the insulation structure.
- Safety measures:Fasten safety belts when working at heights, equip sites with toxic materials with ventilation devices, and regularly check the physical condition of workers.
