防腐管道在生產線上有新突破

時間:2020-5-23 14:19:38瀏覽次數:

     近幾年我國油氣長輸管線發展迅速,而3PE防腐層又是現在最佳的埋地防腐管道方法。塑料擠出機是防腐管道3P防腐出產線上的中心設備之一,其首要由螺桿料筒體系、傳動體系、加熱冷卻體系、上料體系、模具成型體系及控制體系等部分組成擠出機加熱體系有三種加熱辦法:電加熱、流體加熱和蒸汽加熱。在3PE出產線上所用擠出機中,流體加熱及蒸汽加熱很少見,電加熱是最常見的加熱方法。電加熱首要分為電阻加熱和電磁感應加熱兩種,其間電阻加熱又是現在運用最廣泛的加熱辦法。


      而跟著當今社會節能理念的不斷凸顯,根據電磁感應加熱圈高效、節能的特色,越來越多的防腐管道廠家開始運用電磁感應加熱圈。本文首要經過對擠出機電阻加熱圈和電磁感應加熱圈進行比照,論述幾種加熱圈的利害及挑選注意事項。電阻加熱圈電阻加熱圈是鋼管3PE出產線擠出機所運用的傳統加熱方法,電阻加熱圈是使用電流經過具有必定電阻的發熱體而發熱的原理制成的,F在運用最多的是不銹鋼云母加熱圈,陶瓷加熱圈和鑄鋁加熱圈。
