Maagtechnic hose connectors Germany Maagtechnic model Maagtechnic price

Maagtechnic hose connectors connect different hydraulic components (pumps, delivery lines, directional valves, shut-off valves, hydraulic motors, hydraulic cylinders, and some auxiliary components such as level gauges, thermometers, pressure gauges, etc.) to form a closed-loop hydraulic system. Hydraulic pipe fittings serve as connecting accessories in this system. Hydraulic pipe fittings are detachable connectors between oil pipes and oil pipes, or between oil pipes and hydraulic components. They should meet requirements such as easy assembly and disassembly, reliable connection, reliable sealing, small external dimensions, high oil flow capacity, low pressure loss, and good manufacturing processability. Hydraulic pipe fittings are widely used in various aspects of our daily lives. They are mainly used in hydraulic piping systems across industries such as energy, petrochemicals, electric power, shipbuilding, automotive, rail transit, mining, metallurgy, steel mills, offshore engineering, and construction machinery. Construction machinery is the sector with the highest usage of hydraulic pipe fittings.

Maagtechnic hose connector classification

Different names for the same type of pipe fitting are simple to remember: internal connectors have external threads; external connectors have internal threads. Threaded connectors are generally used for pipelines to provide connection. External threads refer to threads on the outside of pipelines, which can usually be touched directly. Internal threads refer to threads inside pipelines, which generally require reaching inside to touch. In industry, you may also encounter right-hand threads and left-hand threads. Right-hand threads tighten by turning clockwise (righty-tighty), which is very common in daily life, with screws being the most typical example. Left-hand threads must be turned in the reverse direction to tighten. These are less common in daily life but frequently seen in specialized fields such as ventilation.

Maagtechnic hose connector manufacturing process

Tee joint forming involves flattening a pipe blank with a diameter larger than that of the tee to approximately the tee's diameter, and opening a hole at the branch location. The pipe blank is heated, placed into a forming die, and a punch for stretching the branch is inserted inside the blank. Under pressure, the pipe blank is radially compressed. During radial compression, metal flows toward the branch direction and forms the branch under the stretching action of the punch. The entire process forms the shape through radial compression of the pipe blank and stretching of the branch section. Unlike hydraulic bulging tees, the metal for the branch of a tee joint is compensated by the radial movement of the pipe blank, so it is also called the radial compensation process. Since the tee is pressed after heating, the equipment tonnage required for material forming is reduced. Hot-pressed tees have wide material adaptability, suitable for low-carbon steel, alloy steel, and stainless steel materials. This forming process is typically used for large-diameter tees and those with thicker wall thicknesses.

Maagtechnic hose connector selection

Metal hose connectors consist of a metal hose body, a stainless steel wire mesh braid, and connector fittings. They can compensate for certain relative displacements and provide vibration damping and noise reduction effects. However, improper selection will not only fail to achieve vibration isolation and noise reduction but may also cause pipeline leakage or even equipment failure due to damage to the metal hose. Selection of metal hoses mainly involves the correct choice of parameters such as nominal diameter, connection type, working pressure, temperature correction, minimum bending radius, and hose length. Nominal diameter, connection type, and working pressure are directly determined by pipeline system requirements and generally pose no issues. It is worth noting that when selecting the design pressure of the hose (which should be greater than the system working pressure), it should not be excessively high, because as the pressure-bearing capacity of the hose increases, its bending capability decreases significantly. Temperature correction and minimum bending radius are fixed for the product and provided by the manufacturer. Problems often arise in the selection of metal hose length. Excessive hose length can cause instability, increase flow resistance, and lead to additional mechanical damage and vibration issues. Insufficient hose length may fail to achieve compensation, vibration damping, and noise elimination purposes, and may also cause excessive bending stress, affecting service life.
