泡沫玻璃预制管壳 430°C
预制泡沫玻璃管壳，耐温430°C，闭孔结构隔绝水汽渗透，安装便捷，切割损耗小。适用于蒸汽管道、LNG低温输送管线及区域供热管网保温。
// 主要特性
- Pre-formed half-shell sections minimize on-site cutting, fitting waste, and installation labor
- Closed-cell glass matrix eliminates condensation risk on cryogenic and chilled pipelines
- Vapor diffusion resistance equivalent to a stand-alone vapor barrier — no separate membrane required
- Maintains thermal and mechanical performance under repeated hot-cold temperature cycling
