Beck hose fittings Germany Beck model Beck price

Beck hose fittings are connection tools between pipes, serving as detachable connection points between components and pipes. Main pipe fittings come in a wide variety; commonly used pipe fittings are generally classified into rigid pipe fittings and hose fittings. Rigid pipe fittings include flared, compression, and welded types, while hose fittings are primarily crimped rubber hose fittings. A compression pipe fitting consists of three parts: the fitting body, the ferrule, and the nut. When the ferrule and nut are placed on the steel pipe and inserted into the fitting body, tightening the nut causes the outer front end of the ferrule to seat against the conical surface of the fitting body, and the inner edge bites uniformly into the seamless steel pipe, forming an effective seal. These are sealed pipe fittings suitable for non-corrosive or corrosive media such as oil, water, and gas. The specification requirements for matching aluminum-plastic pipes are relatively flexible. After connection to the pipeline, they feature reliable connections and good sealing performance.

Beck hose fitting forming methods

Stamping forming of elbows is 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 In the production of common specification elbows, it has been replaced by hot pushing or other forming processes.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, due to low production quantities, 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 a press is used to directly press and form them in a mold. 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 begin pressing. The elbow is formed through the constraint of the outer mold and the support of the inner mold. 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 stretched state, and there is no excess metal from other parts to compensate, 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 the manufacture of small batches and thick-walled elbows. Stamped elbows are divided into cold stamping and hot stamping; cold or hot stamping is usually selected based on material properties and equipment capabilities. The forming process for cold-extruded elbows uses a dedicated elbow forming machine. The pipe blank is placed in the outer mold, and after the upper and lower molds close, the pipe blank moves through the gap reserved between the inner and outer molds under the push of the push rod, completing the forming process. Elbows manufactured using the inner and outer mold cold extrusion process have an attractive appearance, uniform wall thickness, and small dimensional deviations. Therefore, this process is often used for forming stainless steel elbows, especially thin-walled stainless steel elbows. This process requires high precision for the inner and outer molds and has strict requirements for the wall thickness deviation of the pipe blanks. Medium plate welding involves using a press to form half of the elbow profile from medium plate, and then welding the two profiles together. This process is generally used to manufacture elbows larger than DN700.

Beck hose fitting applications

Pneumatic quick-connect fittings are primarily used for air piping and pneumatic tools. These fittings 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 force of the valve springs in the female and male bodies. The valves in the male and female bodies close separately, instantly blocking fluid flow. For two-way shut-off pneumatic quick-connect fittings: during connection, when the male body is inserted into the female body, the sleeve returns to its original position under the action of the spring, 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. The O O-ring can completely prevent fluid leakage.

Beck hose fitting advantages

By changing the sealed connection structure of pipe connectors, the problem of water leakage in the connection between pipe connectors and pipe materials is fundamentally solved, ensuring the sealed connection between pipe connectors and steel-plastic composite pipes. Advantages of PSP flared connections. The device consists of a pipe fitting body with an internal stop shoulder, an adhesive layer coated on its inner wall to bond the inner wall to the outer wall of the connected composite pipe, a sealing ring installed at the internal stop shoulder, and an inner core sleeve inserted into the ring and the connected composite pipe. Advantages of PSP flared connections. Features include simple structure and easy installation. The sealing ring undergoes lateral deformation under the compression of the inner core sleeve to create a double seal, and it also expands automatically upon contact with water for additional sealing. This makes the connection and sealing more reliable. The specification requirements for matching steel pipes are relatively flexible. After welding to the pipeline, it features reliable connections and good sealing performance.
