It is understood that over 80% of aluminum-plastic composite pipes are used for building water supply and radiant heating. Compared with other plastic pipes, aluminum-plastic composite pipes are more suitable for indoor small-diameter water pipes, radiant heating and floor heating, and indoor low-pressure gas pipes. Wait. Since 1997, the Ministry of Construction has restricted the use of galvanized pipes in new residential buildings. It is recommended to use new types of pipes such as aluminum-plastic composite pipes. The market of aluminum-plastic composite pipes has been active all of a sudden and has become a new investment hot spot in China within a few years. , And in early 2000 reached a higher peak of investment, once more than 20 equipment manufacturers, more than 500 aluminum-plastic composite pipe production plant, more than 500 production lines and more than 30 supporting pipe fittings production plant.
After several years of survival of the fittest and several rounds of consolidation, the industry has not experienced the ups and downs of a few years ago. Industry profits are equivalent to the average level of domestic industrial profits. Most small factories with only a few production lines have low equipment levels. The instability of product quality has gradually withdrawn from the market. New competitors have little chance of entering and will maintain stable development in the coming years.
At present, a few large companies in the industry have a perfect ISO quality certification system and supporting pipe fittings technology. Foshan Rifeng is a leading company in the industry. In 1995, the factory introduced German production lines and technologies, and also introduced German testing instruments including testing methods. In 1996, it developed special accessories and installation tools to realize aluminum-plastic composite pipe fittings and installation. Localization of tools; development of large-caliber aluminum-plastic composite pipes in 1998 to fill the domestic gap; by 2000, 47 production lines had been built, with a production capacity of 700,000 meters/day and 200,000 sets of pipe fittings per day, becoming the larger aluminum in Asia. Plastic composite pipe production base, and in 2001 with the government group "Foshan Rifeng Engineering Research and Development Center."
As China's residential construction still maintains a strong momentum of development, it is expected that by 2005, the plastic pipeline will account for more than 50% of the domestic pipeline market, and will reach 80% by 2010. In the new national policy, aluminum-plastic pipes and cross-linked aluminum The plastic pipe is listed as the preferred product in the building water supply plastic pipe, and the cross-linked aluminum plastic pipe is listed as the preferred product of the building heating plastic pipe. With the deep understanding of various new pipe materials, those have perfect product standards and application specifications. The mature products will be more easily accepted by the market.
High Frequency Ranging Sensor Module
A high frequency ranging sensor module is a device that uses high-frequency signals to measure the distance between the sensor and an object. It typically consists of a transmitter and a receiver, which emit and receive high-frequency signals, respectively.
The module works by sending out a high-frequency signal, such as ultrasonic or radar waves, and measuring the time it takes for the signal to bounce back after hitting an object. By calculating the time of flight, the module can determine the distance between the sensor and the object.
High-frequency ranging sensor modules are commonly used in various applications, such as robotics, industrial automation, and automotive systems. They provide accurate distance measurements and can be used for obstacle detection, object tracking, or proximity sensing.
