tracing heat的用法和樣例：
例句
- This trap is suitable for low temperature accompanying heat line pipe and working condition which needs low temperature to discharge frozen water.
該閥適用于低溫伴熱管線(xiàn)和需要低溫排除凝結水的工況。 - The discharge line shall be heat traced when the PSV handles viscous materials or other materials that can solidify as they cool to ambient temperature.
如果壓力安全閥處理粘性介質(zhì)或其它可能凝固的介質(zhì)，因介質(zhì)遇到環(huán)境溫度會(huì )發(fā)生凝固，所以排放管線(xiàn)應安裝伴熱管。
