  产品特点和功能The Performance of Product

  1.预应力真空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,确保了产品在高温下工作的可靠性。

  2.为节约成本,在满足产品性能的条件下,钢级可分别采用L80、P110、N80、J55等形式。

  3.密封环空内充填有吸气剂、气凝胶等,其功能是对污染气体进行清洁,延缓隔热等级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.用预应力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.用预应力真空隔热油管可充分利用地热资源,降低用电成本。

  6.广泛应用于稠油高温注汽、高凝油低温冷采,输油水管线保温,地热水井等领域。

  1.Vacuum prestressed insulated tubing uses prestressing compensation technology to ensure its reliable mechanical properties at high temperature.

  2.In order to save cost, the grade of steel can be used in L80,P110,N80,J55 etc.

  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.The use of geothermal resources, reducing the cost of electricity.

  6.Widely used in the field of high temperature steam injection in heavy oil, Low temperature cold recovery of high pour point oil, Insulation of oil pipeline, Geothermal well etc.
