Product Feature:

1.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.

2.Excellent insulation: between pipe sections are seamless corrugated compensator structures. Interlayer is made of insulation materials of high reflectivity and excellent insulation performance.

3.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.

4.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.

5.High technological content: an optional special vacuum pressure sensor for measuring vacuum is offered if there is a need from user.
