由于海(hai)(hai)(hai)上(shang)異常(chang)惡劣的(de)氣候環境(jing)(jing)，特(te)(te)別(bie)是(shi)在(zai)寒冷的(de)季節(jie)，海(hai)(hai)(hai)上(shang)溫(wen)(wen)度(du)往往會降(jiang)至很低(di)，從而凍結(jie)船舶的(de)排水管(guan)和(he)甲板。因(yin)此(ci)(ci)，船舶正常(chang)運行(xing)需(xu)要(yao)防凍保(bao)溫(wen)(wen)。目前，電(dian)(dian)(dian)伴(ban)熱(re)是(shi)應用廣泛(fan)的(de)伴(ban)熱(re)方(fang)法。電(dian)(dian)(dian)伴(ban)熱(re)產品(pin)(pin)主要(yao)分為兩類:自限溫(wen)(wen)和(he)恒功(gong)率。其中，恒功(gong)率電(dian)(dian)(dian)熱(re)伴(ban)熱(re)產品(pin)(pin)更適合海(hai)(hai)(hai)上(shang)船舶和(he)海(hai)(hai)(hai)上(shang)石油鉆井平臺(tai)的(de)防凍保(bao)溫(wen)(wen)。由于海(hai)(hai)(hai)水溫(wen)(wen)度(du)相對較低(di)，伴(ban)熱(re)環境(jing)(jing)相對復雜，恒功(gong)率電(dian)(dian)(dian)伴(ban)熱(re)產品(pin)(pin)具有(you)溫(wen)(wen)度(du)控制準確的(de)特(te)(te)點(dian)，適用于復雜環境(jing)(jing)下的(de)伴(ban)熱(re)保(bao)溫(wen)(wen)，因(yin)此(ci)(ci)只(zhi)需(xu)在(zai)船舶排水管(guan)道(dao)上(shang)纏繞電(dian)(dian)(dian)伴(ban)熱(re)帶來(lai)補(bu)償熱(re)量損失，維持管(guan)道(dao)的(de)正常(chang)運行(xing)。
