EUROFLUID hose connectors Germany EUROFLUID model EUROFLUID price

EUROFLUID hose connectors refer to threaded pipe fittings, which are the most common type of pipe fittings in industry and daily life. They are mainly used for small-diameter low-pressure pipelines, for parts that require frequent assembly and disassembly, or as final adjustments for pipelines using threaded fittings. The structural form should preferably adopt a metal-to-metal contact sealing structure. Gasket sealing structures are typically used in general pipelines for transporting water, oil, air, etc., and are manufactured from malleable cast iron. The significance of threaded connectors is: threaded connectors make pipe connections simpler and disassembly/replacement easier, greatly saving the cost of pipe connections. They are mainly used for small-diameter low-pressure pipelines, for parts that require frequent assembly and disassembly, or as final adjustments for pipelines using threaded fittings. Features of threaded connectors: high joint strength and good ductility, fully utilizing the strength and ductility of the base material of the reinforcement bar. Convenient, fast, and simple operation. No electricity, no gas, no open flame operations, no oil leakage, and no pollution during construction connection; corrosion-resistant, leak-proof, anti-detachment, safe, and long service life. Application fields: fluid and gas transmission systems in industries related to hydraulics, such as automobiles, construction machinery, lathes, machines, metallurgy, petroleum, mining, construction, chemical industry, shipbuilding, spacecraft, military industry, textiles, marine, entertainment, electronics, etc.

EUROFLUID hose connector technical requirements

Control of the curvature radius is required. For example, if the radius length is 1.5D, then the curvature radius must be within the required tolerance range. Since most of these fittings are used for welding, to improve welding quality, the ends are machined into bevels with a certain angle and edge. This requirement is also quite strict, with regulations on edge thickness, angle, and deviation range. There are many more geometric dimension requirements compared to standard pipe fittings. The surface quality and mechanical properties of the elbow are basically the same as those of the pipe. To facilitate welding, the steel material of the connected pipe must be the same.

EUROFLUID hose connector forming method

Stamping formation of elbows is the earliest forming process applied to mass production of seamless elbows. In the production of commonly specified elbows, it has been replaced by hot pushing or other forming processes, but it is still used for certain elbow specifications due to small production quantities, excessively thick or thin wall thicknesses, or special product requirements. Stamping formation of elbows uses pipe blanks with an outer diameter equal to that of the elbow, directly pressed into shape in a mold 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 mold and the support of the inner mold. Compared with the hot pushing process, the appearance quality of stamping formation is inferior; during the formation of stamped elbows, the outer arc is in a stretched 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 characteristics, the stamped elbow process is mostly used for small-batch, thick-walled elbow manufacturing. Stamped elbows are divided into cold stamping and hot stamping, usually choosing cold or hot stamping based on material properties and equipment capabilities. The forming process of cold-extruded elbows uses a specialized elbow forming machine, placing the pipe blank into the outer mold. After the upper and lower molds close, under the push of the push rod, the pipe blank moves along the gap reserved between the inner and outer molds to complete the forming process. Elbows manufactured using the inner and outer mold cold extrusion process have an aesthetically pleasing appearance, uniform wall thickness, and small dimensional deviations, so 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 molds; the requirements for wall thickness deviation of the pipe blank are also quite stringent. Medium plate welding fabrication involves using a press to make half of the elbow profile from medium plate, and then welding the two profiles together. This process is generally used to manufacture elbows above DN700.
