On March 16th, with the strong support of Lijiang Municipal Committee and Municipal Party Committee of Yunnan Province and Party Committee of the Corps, the first GSSI radar life detector introduced from the United States settled in Lijiang City Fire Fighting Force. The first high-tech new equipment will increase the emergency rescue capability of Lijiang fire-fighting forces in the face of various special disaster accidents, and will play an important role in promoting the city's “Safe Lijiang and Harmonious Societyâ€. The purchased radar life detector is worth more than 400,000 yuan. It can be widely used in fire sites, rivers, lakes, mountains, earthquake landslides, mine explosions, surviving target searches, and confirmation of survivors. It can also be used to track search and rescue personnel. Life safety. In order to increase its effectiveness, the Lijiang Detachment organized officers and soldiers to learn and operate the equipment for the first time. Through learning to understand, the equipment is mainly composed of a radar detector and a palmtop computer. Its working principle is: in someone trapped in the rubble, it is determined whether there are individual living individuals by transmitting radio waves and receiving radar waves that are returned from the breathing activities of individual life individuals. exist. With the characteristics of high technology content, large search scope, small size, light weight, strong penetrating ability, and convenient on-site installation and operation, it can detect people's breath within 5 meters through general-purpose structural wall materials and building ruins. The range of people within the range of movement and other life characteristics, and can accurately measure the depth of the buried body of life, search the body of life within 30 seconds have results, confirm the results within 2 minutes, to complete the rescue task with the highest efficiency.
The deployment of radar life detectors has made up for the shortcomings of traditional life detectors in the area of ​​rescue and improved the rescue capabilities in the event of building collapses, landslides, and earthquakes. Radar Life Detector settled in Lijiang City Fire Brigade, marking Lijiang City fire brigade rescue equipment and technology to a new level.
Alloy pipe is a kind of seamless Steel Pipe, its performance is much higher than that of general seamless steel pipe, because this type of steel pipe contains more Cr, its high temperature resistance, low temperature resistance, corrosion resistance performance is much better than other Steel pipe, so the alloy pipe is widely used in petroleum, aerospace, chemical, electric power, boiler, military and other industries.
Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low-alloy steels and high-alloy steels. The difference between the two is somewhat arbitrary: Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.Most commonly, the phrase "alloy steel" refers to low-alloy steels.
The biggest advantage of the alloy steel pipe is 100% recycled, which highly meets our national`s strategy of environmental protection, energy and resource saving. Alloy steel pipes have hollow section, which can be used for conveying fluids, such as conveying oil, gas, water and some solid materials, etc.
