Hanchen hose fittings Germany Hanchen models Hanchen prices

Hanchen hose fittings are widely used in high-pressure piping applications in industrial fields, such as shipbuilding, offshore oil, metal processing, and mining. Flared tube fittings are suitable for hydraulic, lubrication, high-pressure water jetting, and high-pressure air pipelines. Flared tube fittings have been certified by many auditing bodies; they offer high reliability, inherent cleanliness, and strong flexibility, with faster and simpler pre-assembly and installation. Flared connections require no welding, saving subsequent processes such as pickling and flaw detection. Flared tube fittings are a type of quick-connect fitting suitable for various pipe fittings and tubes with nominal pressures not exceeding 32MPa. According to the manufacturer, flared connections are widely used in industries such as oil refining, chemical, light industry, textiles, national defense, metallurgy, aviation, automotive, pharmaceuticals, machinery, shipbuilding, natural gas, and CNG refueling stations.

Hanchen hose fitting structure

Includes a female connector body with a through-hole containing a steel ball; a male connector post with a groove on its surface; and a ferrule. The female connector body and male connector post form a sealed fit, with the steel ball on the body engaging the groove on the post. The ferrule is fitted over the outer surface of the female connector body. It is characterized by also including a pull sleeve, which is fitted over the surface of the male connector post and connects to the ferrule on the female connector via its internal thread.

Hanchen hose fitting precautions

Open type: When the mold connectors and mold water nozzles in high-pressure water hose quick-connect fittings are in an open state, the copper sleeve on the female head is pushed to the other end when disconnected, causing the steel balls to roll outward automatically and allowing the male head to be removed. In this case, since neither the male nor female heads have valves, fluid will flow out. In the connected state, the male head is inserted into the female head, and the copper sleeve is pushed back to its original position by spring force, locking the steel balls. Fluid flows, and the O ring prevents fluid from leaking out. Combined water hose quick-connect fittings: When the mold water nozzles in high-pressure water hose quick-connect fittings are open and the mold connectors are closed, the copper sleeve in the female head moves to the other end when disconnected, causing the stainless steel balls to roll outward automatically. The male head is opened by the reaction force of the valve spring, closing the valve automatically to block fluid flow. In the connected state, the male head is inserted into the female head, pushing the copper sleeve back to its previous position via spring force to lock the steel balls, allowing fluid to flow. The O ring in the high-pressure water hose quick-connect fitting prevents fluid from leaking out.

Three-way water pipe connector, solution for quick-connect water pipe fittings. This process is very fast. Many friends may not be particularly familiar with high-pressure quick-connect water hose fittings. In fact, this type of water pipe is quickly connected at faucets, spray guns, and water pipelines. This method is labor-saving and particularly convenient. The method for quick-connecting high-pressure water hose fittings is as follows: First, install quick-connect fittings on both ends of the water pipe, gently tightening the adjacent nuts. Next, connect the faucet connector or use the spray gun connector. If you hear a "click" sound during this process, it indicates that the high-pressure water hose quick-connect fitting has been completed. Closed water pipe connector method: When the mold connectors and mold water nozzles in high-pressure water hose quick-connect fittings are closed, the female and male heads block the pipe channel under the force of their respective pins and springs when disconnected. The pins on both the male and female heads close individually, instantly blocking fluid flow. In the connected state, when the male head is inserted into the female head, the pins return to their original positions under spring action. Steel balls roll and lock to tightly connect the male head, while the pins on the male and female heads push against each other to open, allowing fluid to flow. The O ring in the high-pressure water hose quick-connect fitting completely prevents fluid leakage.
