据报道,美国伺服仪表公司(ServometerCorp)已经制造了一种超薄壁电成型波纹管,其性能如下:1.壁厚可达0.0003时(0.0076毫米),灵敏度很高;2.可挠性好;3.伸长量可为原长的60％,并且可增大内、外径的比值;4.使用寿命长,疲劳周期在10万次以上;5.可用作联接件,因其材质是非多孔性的,故不会带来污染问题。用氦质谱仪测其泄漏量为10~(-9)毫升/秒;6.小型,外径仅达0.035时(0.89毫
It has been reported that ServometerCorp has manufactured a thin-walled electric wall corrugated pipe, the performance is as follows: 1. The wall thickness of up to 0.0003 (0.0076 mm), high sensitivity; 2. Flexible ; 3 elongation of 60% of the original length, and can increase the ratio of internal and external diameter; 4 long life, more than 100,000 cycles fatigue; 5 can be used as a coupling, because of its material Non-porous, so it will not bring pollution problems. Spray volume measured by helium mass spectrometer was 10 ~ (-9) ml / s; 6. Small size, outer diameter of only 0.035 (0.89 milliamperes
