   产品特点和功能The Performance of Product

 
  1、隔热油管的内管受到蒸汽热量影响时,可释放预施加的拉应力,以补偿内外管温差伸长,确保产品高温下工作的可靠性。
  2、该产品是为了克服接箍处热损失严重的问题而设计。
  3、密封环空内充填有吸气剂、气凝胶其功能是对污染气体进行清洁,从而延缓了系统随时间增加隔热性能下降的趋势,使产品在长期工作中保持良好的隔热性能。
  4、用隔热油管注汽可以使注汽热损失大幅度降低,大大提高了可注入深度和注入油层的蒸汽质量。
  5、端部连接为特殊螺纹,可以达到气密封等级,远远高于API螺纹。
  6、降低了套管和水泥环的热应力,防止套管高温损坏。
 
  1、The inner tube uses prestressing compensation technology to ensure its reliable mechanical properties at high temperature.
  2、Reduces the heat loss of energy at the Coupling.
  3、The seal ring is filled with getter / aerogels etc, the product has good thermal insulation performance, it plays an important role in preventing heat loss in insulated tubing.
  4、Reduces the heat loss, certainly the steam quality and the depth of steam injection can be increased.
  5、As a special thread end connection, the hermetic seal level is much better than API threads.
  6、Minimizes heat stress on casing and cement mantle, protect the casing from damage by high temperature.
