3F Filippi hose connector Germany 3F Filippi model 3F Filippi price

3F Filippi hose connector This hose connector is a terminal type, used as a straight connector to attach metal hoses to enclosures; it is a detachable connection point between components and pipes. It plays an indispensable role in pipe fittings and is one of the two main components of hydraulic piping. Hose connectors are high-quality flexible pipes in modern industrial piping systems. They mainly consist of bellows, a wire braid, and connectors. The inner tube is a thin-walled stainless steel bellows with a spiral or annular shape, and the outer braid of the bellows is woven from stainless steel wire or steel strip according to specific parameters. The connectors or flanges at both ends of the hose match the connectors or flanges of the customer's piping. The bellows of the hose are formed by high-precision plastic working of extremely thin-walled seamless or welded stainless steel pipes. Due to the elastic characteristics of the bellows profile, the hose has good flexibility and fatigue resistance, making it easy to absorb cyclic loads from various motion deformations, especially the ability to compensate for large displacements in piping systems.

In addition to the standard specifications below, sizes and thread standards can be varied arbitrarily according to requirements.

3F Filippi hose connector selection

Metal hose connectors consist of a metal tube body, a stainless steel wire braid, and connector fittings. They can compensate for certain relative displacements, providing vibration damping and noise reduction effects. However, if selected improperly, they will not only fail to provide vibration isolation and noise reduction but may also cause pipeline leakage or even equipment failure due to damage to the metal hose. The 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 the piping system requirements and generally do not pose problems. 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 too 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. The problem we often encounter is the selection of the metal hose length; if the hose is too long, it will cause instability, increase flow resistance, and lead to additional mechanical damage and vibration issues. If the hose is too short, it may fail to achieve compensation, vibration damping, and noise elimination, and may also cause excessive bending stress, affecting service life.

3F Filippi hose connector installation

Since the vibration direction of the equipment is primarily vertical up-and-down vibration, the metal hose mainly compensates for axial displacement. We know that metal hoses themselves cannot compensate for axial displacement in their natural state, so such installation and usage will inevitably result in the metal hose being unable to withstand strong axial tension, leading to rupture and thus pipeline leakage. During installation, relative twisting occurs at both ends of the metal hose. This mainly appears when both ends of the metal hose are flange-connected. At the installation site on ships, installation errors often cause the flange holes at the two connected ends to be misaligned and offset. It is mistakenly assumed that the hose connector can compensate for torsional displacement, but in reality, the metal hose itself cannot compensate for this torsional displacement, resulting in the metal hose being twisted off and the pipeline leaking. In this case, a metal hose with a loose flange connection at one end can be used for connection. During installation, there is a large radial offset at both ends of the metal hose. Although the metal hose itself can compensate for lateral displacement, if there is a large relative radial displacement at both ends during installation, the actual compensatable amount in that direction will be reduced. This may result in the required compensation in that direction during use exceeding the actual compensatable amount of the hose in that direction, causing fatigue damage and failure of the metal hose.
