AFY hose connector Germany AFY model AFY price

AFY hose connector is a type of hose connector mainly composed of three components. Metal hose connectors are used in many applications. The main component of the metal hose connector, the bendable part, is made of braided metal wire. Metal hose connectors offer excellent performance and come in a wide variety. Different types of metal hose connectors have different characteristics, structures, and maximum temperature ratings.

Common problems with AFY hose connectors

1. Remove residue: When installing water pipe connectors, completely remove various residues from the pipeline. This prevents valve core damage, blockage, clogging, and leakage. At the same time, clean the surface to avoid residual construction materials. 2. Do not apply excessive force during switching: For any household accessory, do not use excessive force when switching; simply shake or rotate. Even traditional home fixtures can be tightened without excessive effort. In particular, do not use the handle as a railing for support. After a period of use, disassemble and clean products with outlet filter covers to remove debris. Products with plastic hoses should be kept in a naturally stretched state to prevent rupture. 3. Keep household tee connectors flexible: The shower metal bellows of household hose connectors should be kept in a naturally stretched state. Do not wrap it around the faucet when not in use. At the same time, whether in use or not, ensure that no blind spots form at the connection between the plastic hose and the valve body to prevent hose rupture or damage. 4. Pay attention to regular cleaning: Domestic water pipe connectors that are not used for long periods may also lead to incomplete closure, water leakage, loose handles, loose connectors, and leaks, which customers can often handle themselves.

AFY hose connector process

Stamping forming: Stamping forming of elbows was the earliest forming process applied to mass production of seamless elbows. In the production of common specification elbows, it has been replaced by hot pushing or other forming processes. However, for certain elbow specifications with low production volumes, excessively thick or thin wall thicknesses, or special product requirements, it is still in use. Stamping forming of elbows uses pipe blanks with an outer diameter equal to that of the elbow, and they are directly pressed into shape in a die using a press. Before stamping, the pipe blank is placed on the lower die, the inner core and end die are inserted into the pipe blank, and the upper die moves downward to start pressing. The elbow is formed through the constraint of the outer die and the support of the inner die. Compared with the hot pushing process, the appearance quality of stamping forming is inferior. During the forming of stamped elbows, the outer arc is in a tensile state, with no excess metal from other parts for compensation, so the wall thickness at the outer arc is reduced by approximately 10%. However, due to its suitability for single-piece production and low cost, the stamped elbow process is mostly used for small-batch, thick-walled elbow manufacturing. Stamped elbows are divided into cold stamping and hot stamping, and the choice between cold or hot stamping is usually based on material properties and equipment capabilities. The forming process of cold-extruded elbows uses a dedicated elbow forming machine. The pipe blank is placed in the outer die, and after the upper and lower dies close, the pipe blank moves along the gap reserved between the inner and outer dies under the push of the push rod to complete the forming process. Elbows manufactured using the inner and outer die cold extrusion process have an attractive appearance, uniform wall thickness, and small dimensional deviations. Therefore, this process is mostly used for forming stainless steel elbows, especially thin-walled stainless steel elbows. This process requires high precision for the inner and outer dies and has relatively strict requirements for the wall thickness deviation of the pipe blanks.

AFY hose connector material classification

High-pressure tees. There are two commonly used types of high-pressure tees: welded high-pressure tees and integrally forged high-pressure tees. Welded high-pressure tees use high-quality high-pressure steel pipes as material. The manufacturing method is similar to cutting a hole and connecting a pipe; the hole opened on the main pipe must match the diameter of the branch pipe to be connected. Strict welding quality is required, typically requiring preheating before welding and heat treatment after welding. Their specifications and pressure ranges are the same as those of high-pressure elbows. Integrally forged high-pressure tees generally use threaded flange connections. Their specification range is DN12~DN109mm. The service temperature for 25# carbon steel high-pressure tees is below 200℃, and for low-alloy and stainless acid-resistant steel high-pressure tees, it is below 510℃. The service pressure is below 20.?0MPa. There are 3 types of commonly used welded tee pipes: bent pipe type, right-angle type, and flat weld port type. 1) Same-diameter bent pipe welded tee: Commonly known as pants-type pipe, it is made by cutting off half of the circumferential pipe wall at the outer arm of two 90° bent pipes, and then butt-welding the remaining two bent pipes together to form a same-diameter tee. 2) Right-angle tee fabrication: Available in same-diameter and different-diameter types. During fabrication, development drawings are drawn based on two intersecting cylindrical surfaces. Oxygen-acetylene flame cutting tools are generally used for cutting, followed by welding. 3) Flat weld port tee: The tee weld seam is short, deformation is small, it saves pipe material, and processing is simple. The manufacturing method involves cutting an elliptical hole in a straight pipe, where the minor axis of the ellipse equals 2/3 of the branch pipe's outer diameter, and the major axis equals the branch pipe's outer diameter. Then, the pipe walls on both sides of the elliptical hole are heated to approximately 900℃ and flanged outward to form a round opening.
