查询词典 two-pipe system

Therefore, we developed a call "NaMi-863" of thermoplastic pipe (the franchise has been granted, state: ZL200620009651.8) It is mainly iron pipes do not solve the basic acid-fast, short life-corrosion flaws , As long as 50 years of its life, but also a metal pipe to solve the water pollution, never to corrosion, but also solved the general strength of small plastic pipe, the flange-shedding and other shortcomings, and its strength has greatly exceeded its design Requirements, specifications and the same iron pipes, iron pipes is the alternative.

因此我们研制出一种叫&NaMi-863&的热塑钢管(已被国家授予专利权号：ZL200620009651.8)它主要解决了铁管不抗酸碱性，易腐蚀寿命短的缺点，它的寿命长达五十年，同时也解决了金属管子对水的污染。它永不腐蚀，也解决了普通塑料管强度小、法兰盘易脱落等缺点，它的强度大大超过了其设计要求，规格与铁管相同，是铁管的替代品。

Following, a experiment has been carried out, the incident waves with a frequency band of 200kHz-3 50kHz are used to the experiment, and a series of peak value-time curves are drawn each 10kHz, corresponding time are found through fitting peak value, thus the position of the defect is calculated accurately. The application of awl-shaped sensor head in the heat change water pipe experiment indicates that the ultrasonic guided waves may transmit nearly 50 meters in the pipe, which is not influenced by the elbows and makes it possible to test defects in long distance and large-scale. The water-load pipe experiment indicates that the displace and energy maybe leakage at the near-surface, which is significant for the further research.

而后，采用200kHz至350kHz频段的入射波进行了实验验证，并每隔10kHz绘出一条峰值一时间的曲线，通过拟合峰值点，找到对应的时间，从而准确的计算出了缺陷的所在；应用锥形探头的热交换水管的实验表明，超声导波可以在管道中传播了近50米的距离，且不受弯头的影响，从而使得长范围、大规模检测成为可能，水载管实验说明了离面位移和能量可能会发生泄漏的特性，为导波的深入研究和应用作了铺垫。

Pipe heat causes linesr expansion and rurtherresult in tensile stress in the direction of pipe xale to make cracks in direction perpendicular to the axle,in the case ,the stress value is obtained by ormula=E,and if ,it is estimated with 15mm LG PEX-A Pipe as base,the sectional breaking rorce is estimated approx.7.6kg/cm2,being much more little comparing with the concrete bearing force=1,536kg/cm2and its not needed to be anxious to concrete cracking rising.

由于管子的线性热膨而使管子受轴向伸长力，从人在与管轴成直角的方向上产生裂缝，这时的应力接计算，PEX－A按直径15mm标准计算进断面破坏强度约为7.6kg/cm2，比混凝土的支持力1.58kg/cm2小得多，所以不需要考虑管子对混凝土的破坏作用。
