Quick Fittings is a high-quality pipe joining product designed to meet the needs of a variety of industrial and construction applications. Kuaiyi pipe connection technology is widely used in heating, domestic water supply, and air conditioning systems of residential buildings, commercial buildings, and industrial buildings in Europe and North America. It has been proven through long-term practice that it is a reliable water connection system. It is made of high-quality CW617N brass in accordance with UNE-ISO-15875 standards. Since the brass material has good corrosion resistance and reliability, it can withstand high-pressure and high-temperature environments, ensuring the safe and stable operation of the pipeline system. This extends the life of the joint and reduces replacement costs. In addition, it is easy to install and can connect pipes quickly and effectively, improving work efficiency and reducing costs. Kuaiyi pipe fittings can be widely used in petroleum, chemical industry, electric power, papermaking, food processing and other industries, and are suitable for the transportation and processing of various media. Whether on industrial production lines or construction sites, Kuaiyi pipe fittings can exert their superior performance to ensure the stable operation of the pipeline system and meet the needs of different industries.1. Select appropriate pipe fittings, quick rings and diameter expansion tools. 2. Use pipe scissors to cut the pipe vertically to ensure that the pipe opening is flat. 3. Put the tube on the Quick-Easy ring and observe that the tube is inserted all the way. 4. Use the expansion tool to expand the diameter so that the quick ring and pipe are completely opened. 5. After putting down the tool, quickly (up to 3-5 seconds) insert the pipe into the end of the pipe fitting and hold for a few seconds. 6. After waiting for a few seconds to a minute, the quick ring and pipe will return to their original shape and tighten naturally. 7. At room temperature (above 20 degrees), the pipeline pressure test can be performed after 30 minutes. This method does not require skilled workers, and the key points of the operation are only one expansion and one insertion, which is simple and clear.
