詳細信息
  三相恒功率電熱帶和單相恒功率電熱帶的原理基本相同,不同之處是單相帶采用單相供電,三相采用三相三角形供電,三相帶除有單相電熱帶的特點外,特別適用于長距離,大口徑管道的伴熱和保溫,可用于工廠一區、二區的爆炸性氣體混合物T3相吻合。

  Three-phase constant power heating tape has same principle as single-phase constant power heating tape,the difference is single-phase type uses single-phase power supply but three-phase type uses three-phase triangle power supply,Besides the features of single-phase heating tape,three-phase type is especially suitable for heat tracing and preservation of long-distance and large-caliber pipelines,which can be used in zone two of explosive gas mixture T3 in the factory.

 
產品結構與工作原理
  電源母線為二根平行絕緣銅線,在內絕緣層上纏繞電熱絲,并將電熱絲每隔一定距離(即“發熱節長”)與母線連接,形成連續并聯電阻。母線接通電后,各并聯電阻發熱,因而形成一條連續的加熱帶。

  Power buss wires consists of two parallel insulation copper wires with heating wires winded to inner insulation layer ,heating wires will be connected to busswires every certain distance(heating section length)which forms continuous parallel resistances,After power on of buss wires,all parallel resistances will heat and form a continuous heating tape.

 
適用區域
  單相恒功率電熱帶主要用于各種管道、儀表的防凍、保溫、最高維持溫度150度,可用于工廠一區、二區爆炸性氣體場合。

  Single phase constant power heat tracing tape is mainly applied in antifreezing and heat preservation of various pipelines and instruments,with max/naubtebabce teno,150度,sa well as zone one and zone two of explosive gas places in the factory.

 
產品特點及應用場合
  恒功率電執單位長度的發熱量恒定,使用的電熱帶越長,輸出的總功率越大,該電熱帶在現場能夠按實際需要長度任意剪切,或者在一定范圍內接地使用,并允許多次交叉重疊使用,此外具有柔韌性,可以方便地緊貼管道表面敷設,電熱帶外層的編織層不僅起著傳熱和散熱的作用,提高電熱帶的整體強度,同時還能作為安全接地線。
  本電熱帶適用于管道,閥門、泵體的伴熱、防凍和保溫,或者維持儀表管線的工藝溫度。
  A、用于在正常情況下連續流動的低凝固管線使用,可避免介質因停止流動而凝固。
  B、需要嚴格控制作業溫度的液體管線的伴熱和保濕(須配用溫度控制器)
  C、寒冷地區自來水管道及閥門的防凍、排水管、抽水管和冷凝管路的防凍
  D、沿海井臺管道的伴熱保溫
  E、一般管線和儀表管線的伴熱保溫
  F、井口采油樹伴熱(取代水套爐),污水井伴熱
  G、混凝土預制防凍養護

  With constant heat value in unit length for the constant power heating tape,the longer of heating tape is ,the bigger of total output power will be,The heating tape can be cut at random as needed length on the spot,or be used within certain range by grounding,allowing multiple overlapping,ln addition,its flexibility can make it adhere to pipeline surface for convenient layout,Outer braid of the tape not only make the function of heat transmission and heat dissipation but improve whole strength of the tape,meanwhile as safe ground wire.
  A、Continuous flowing low-freeze pipeline under normal condition to avoid medium freeze due to flow stop.
  B、Heat tracing and preservation of liquid pipeline whech needs strictly controlled process temperature.(temperature controller to be equipped)
  C、Antifreeze of water supply pipeline and valve in cold area,as well as antifreeze of discharge pipe,suction pipe and condensation pipeline.
  D、Heat tracing and preservation of coastal well pipeline.
  E、Heat tracing and preservation of general pipelines and instrument pipelines.
  F、Heat tracing of wellhead tree.(instead of water jacket heater and bilge well)
  G、Antifreezing maintenance for concrete fabricated part.
