生产材料：Production Materials:
内外管采用无缝不锈钢，材质为0Cr18Ni9。
Inner and outer tubes are made of 0Cr18Ni9 seamless stainless steel. 
产品特点：Product Feature:
结构**：内外管支承采用自动定心的刚性支承，*避免了由于管道挠度或不合理支承引起的内外管短路导致的冷损。
Structural innovation: automatic centering rigid support is used for inner and outer tubes so that cold loss brought about by short circuit of inner and outer tubes due to pipe deflection or unreasonable support is prevented. 
绝热性能优良：管段间采用无缝波纹补偿结构。夹层采用高反射率的绝热材料，绝热性能优良。
Excellent insulation: between pipe sections are seamless corrugated compensator structures. Interlayer is made of insulation materials of high reflectivity and excellent insulation performance. 
产品寿命长：外管安装有活动真空阀，密封真空度高，可反复抽真空。改变了传统产品“一次性真空”较易导致真空度低、真空寿命短、蒸发损失高的缺陷。
Long service life: outer tube has adjustable vacuum valve so that degree of sealed vacuum is high. The vacuum can also be pumped repeatedly. However, some defects like low vacuum degree, short service life and high evaporation loss in “one-off vacuum” of traditional product are removed.
安全**性高：活动真空阀可自动压紧，自动复松。若夹层真空被破坏导致**压等异常情况，可自动泄压。
High safe reliability: adjustable vacuum valve can fasten or loosen itself. It can also decompress itself when overpressure brought about by damaged vacuum interlayer occurs. 
技术含量高：若用户需要，可选配**真空压力传感器进行真空测量。
High technological content: an optional special vacuum pressure sensor for measuring vacuum is offered if there is a need from user.
