Product Name: Jiangxi Telescopic device


Jiangxi, referred to as Gan, is one of the 23 provinces in China, and Nanchang is the capital. Jiangxi is located in the southeast of China, on the South Bank of the middle and lower reaches of the Yangtze River. It belongs to East China, bordering Zhejiang and Fujian in the East, Guangdong in the south, Hunan in the west, and Hubei and Anhui in the north.


What is the use of the pipeline expansion device? Does the expansion device prevent the water pipe from hot expansion and cold contraction? Yes, do you have to apply pressure to install butterfly valve, telescopic device and gate valve?

In brief, the expansion device can extend or contract, and can remove the in-situ stress caused by heat expansion and cold contraction of the pipeline. In addition, it has the function of shock absorption, such as valve, pipeline pressure, system software pressure, etc. when the gate valve is in the original factory, the pressure test will be carried out;

The expansion device is used to remove the ground stress caused by heat expansion and cold contraction! Valve in the original factory will appear before the AC withstand voltage test, you think the pressure should be the pipeline closed test! Mainly depends on the pipeline construction has wood leakage area!

In order to ensure the safety of the pipeline network application, the heating pipe adopts the temperature expansion type of compensation pipeline in the network, so as to prevent the bending or cracking of the pipe due to bearing its own approved thermal stress. The structure of the pipeline expansion device: the elbow of the pipeline is used to play a telescopic role. 1. U-type expansion joint. 2. Wave type expansion expansion device. 3. Waterproof sleeve expansion device.
