The design concept of "clamp type" connection is to reduce "live joint" in concealed parts and increase "dead joint", so as to prevent all kinds of vibration and other environmental effects from leaving hidden water leakage.

There is no need to twist teeth, weld or hot melt in the "clamping type" connection. Instead, high-precision professional tools are used to complete the connection instantly. The operation is safe and hygienic. The inner wall of pipe fitting and pipe are almost the same diameter, and there is no water stop. It reflects the advanced operation process of high-tech products and a perfect system engineering: pipe fitting, pipe material, rubber ring and all kinds of tools must meet the requirements It's quite accurate.

The basic principle of "clamping type" connection is: the leakage protection is realized by the radial contraction and tightening of rubber O-ring. The EPDM O-ring has been proved by test that it can adapt to the temperature of - 25 ℃ - + 125 ℃ and has no ultraviolet radiation, so it is durable; the pipe and pipe fittings are clamped into hexagonal shape by special clamping tools to realize anti rotation; the clamping position is deformed, small in the middle and big at both ends The test shows that the pressure resistance of the clamping connection can reach more than 35kg.

Compression type connection (aluminum plastic pipe)

1. Compression type connection is the most advanced connection of aluminum-plastic pipe, also known as watertight joint. It has the highest connection reliability and the best cold and hot cycle resistance. It can realize zero leakage of aluminum-plastic pipe connection. This kind of joint is widely used in cold and hot water supply, heating and gas fields. 2. The "compression set rate" of O-ring rubber, which plays a key role in sealing performance, is required to be less than 20% in foreign standards, and EPDM rubber sealing ring with better weatherability has been widely used for a long time; however, it is not specified in domestic product standards, and the traditional NBR sealing ring is still used. 3. At present, the mainstream in the market is the first generation ferrule type copper connector, and the safest second generation clamp type copper connector can also be seen.
