HANSA hose connector Germany HANSA model HANSA price

HANSA hose connectors are components used to connect water pipes. Connectors can be classified by usage method into: external thread end-connecting water pipe connectors, compression-type water pipe connectors, and self-locking water pipe connectors. External thread end-connecting water pipe connectors are die-cast from zinc alloy, with surfaces galvanized, sandblasted, or chrome-plated; they feature a compact structure, are free of pores, and have high strength. Compression-type water pipe connectors can connect threaded-less steel pipes to hoses, eliminating the threading process; simply screw in the fastener. They feature a compact structure and high strength. Water pipe connectors can connect threaded-less steel pipes or threaded-less equipment cable outlets to hoses, eliminating the threading process; they are die-cast from zinc alloy, with surfaces galvanized, sandblasted, or chrome-plated; they feature a compact structure and high strength. Widely used in high-end buildings, hotels, hospitals, office towers, stadiums, museums, government agencies, villas, and residential communities.

HANSA hose connector functions

Whether pneumatic quick-connect couplings or manual quick-connect couplings, both are coupling tools for sealed connections; the difference lies in whether they are driven by air pressure or manually. In different application projects, the roles and advantages of pneumatic quick-connect couplings vary. Stainless steel tubes have a smooth surface, high hardness, and resistance to high temperatures and pressures, and are often used as materials for precision equipment components. Qualified inspections must be performed on stainless steel tubes, including airtightness testing. According to feedback from test engineers, as shown in the figure above, one end of the stainless steel tube has been welded shut, and pressure must be applied from the other end to test the sealing of the weld joint. In this case, pneumatic quick-connect couplings can be used, employing an outer-clamping sealed connection to better ensure inflation speed. After connecting the corresponding air lines to the coupling, if used for automated or semi-automated operations, the mounting holes must also be connected to the corresponding cylinder fixtures. Here, the role of the pneumatic quick-connect coupling is to provide sealed connectivity for pipe fittings, assist in testing, improve test efficiency, and enhance test stability. Its advantages include more convenient pneumatic operation, O-rings that clamp the tube wall without causing scratches, and stable sealing for more accurate test results. In practical applications, one end of a plastic pipe fitting is connected to the equipment, which uses other methods for internal pressurization; here, the pneumatic quick-connect coupling serves to seal the pipe opening. Plastic pipe fittings generally have low hardness, are easily damaged, and are prone to scratching. Due to batch production and inspection, pneumatic couplings are required to integrate automated operations. Their advantages include being gentle on the test piece tube walls without causing scratches, suitability for various pipe materials and properties (including some hoses), and ease of integration into automated operations to improve efficiency.

HANSA hose connector material classification

Malleable iron tee. The manufacturing materials and specification ranges for malleable iron tees are the same as those for malleable iron elbows (please refer to the previous introduction to malleable iron elbows). They are mainly used for indoor heating, water supply and drainage, and gas pipelines. Cast iron tee. Like cast iron elbows, cast iron tees are cast from gray cast iron, and the commonly used specifications and pressure ranges are the same. Depending on the connection method, they are divided into socket cast iron tees and flanged cast iron tees. Socket cast iron tees are mainly used for water supply and drainage pipelines; water supply pipelines mostly use 90° straight tees; drainage pipelines typically use 45° branch tees to reduce fluid resistance and prevent pipe blockage. Flanged cast iron tees are generally 90° straight tees and are mostly used for outdoor cast iron pipes. Steel tee. To manufacture standard tees, molds are usually required, involving processes such as cutting, hole punching, and heating, followed by machining to create medium- and low-pressure steel tees, which are welded during on-site installation. There are two scenarios for tees used with steel plate rolled pipes: one is cut from steel plates at the processing plant and formed by rolling and welding; the other involves cutting holes and connecting pipes during on-site installation.

HANSA hose connector applications

Pneumatic quick-connect couplings are primarily used for air piping and pneumatic tools. These couplings allow pipeline connection or disconnection without tools. When disconnected—when the sleeve of the female body moves to the other end—the stainless steel balls automatically roll outward, and the male body disconnects under the combined spring force of the valves in the male and female bodies. The valves in both the male and female bodies close, instantly blocking fluid flow. Double-shut-off pneumatic quick-connect couplings: When connected, as the male body is inserted into the female body, the sleeve returns to its original position under spring action, and the steel balls roll to lock the male body tightly. Simultaneously, the valves in the female and male bodies push against each other to open, allowing fluid flow, and the O O-ring completely prevents fluid leakage.
