By smelting, certain raw metals can be isolated from certain minerals: iron, tin, copper. But a person quickly figured out that if the metals were mixed in certain proportions, then the resulting mixture could have properties that surpass the properties of each of the original components.
A striking example is bronze, a mixture of tin and copper. The initial metals are soft, fragile, but it is worth mixing them, as the strength of the final product will increase significantly. Another variant of this alloy, obtained by adding zinc, is called brass.
Brass
In fact, brass is a mixture of copper, zinc and sometimes other metals. Nickel, tin, lead, iron or manganese are added to it to obtain greater strength, ductility, hardness or toughness. For use as an element of water supply systems or oil pipelines, high-load lines and pneumatic systems, brass is ideally suited precisely due to its relatively high strength and at the same time some plasticity, which allows two parts when tightened to qualitatively adjoin each other and O-rings . A brass fitting and a beautifully shiny golden brass coupler allows the hose to be crimped, deforming the outer sheath while maintaining a tight seal on the inner.
Coupling depending on version:
-
tear-off - for non-persistent connection,
-
threaded - to create one-piece fluid supplies within production cycles,
-
plug-in - with and without sealing.
Any coupling experiences radial and axial loads. Brass is resistant to this kind of use, therefore it is used in critical units. Its electrical neutrality and resistance to corrosion have led to widespread use of brass fittings in a wide variety of applications - from aircraft to water supply, from gardening to rocketry.
To maintain performance over the entire service life, brass parts must be made of a homogeneous high-quality alloy, accurately milled on numerically controlled machines and have sufficient stiffening ribs, depending on the diameter and pressure of the medium.
All these parameters are taken into account by the engineers of the leading hydraulic systems company HansaFlex, which has put innovation and deep engineering experience at the forefront. In a well-functioning production, high-precision processing eliminates the spread of indicators, and computer modeling allows you to debug the process of producing high-quality brass couplings as for high and for low pressure. Thanks to productive cooperation with large industries and industrial consumers, specialists know exactly the loads in the nodes of oil systems and choose excellent brass for connecting and shut-off valves.
