HERION hose fittings Germany HERION model HERION price

HERION hose fittings are end-type straight connectors used to connect metal hoses to enclosures; they are detachable connection points between components and pipelines. They play an indispensable role in pipe fittings and are one of the two main components of hydraulic piping. Hose assemblies are high-quality flexible pipes in modern industrial piping systems. They mainly consist of bellows, a wire braid, and fittings. The inner tube is a thin-walled stainless steel bellows with a spiral or annular shape, and the outer wire braid over the bellows is woven from stainless steel wire or steel strip according to specific parameters. The fittings or flanges at both ends of the hose match the fittings or flanges of the customer's pipeline. The bellows of the hose are formed by high-precision plastic deformation of extremely thin-walled seamless or welded stainless steel pipes. The elastic characteristics of the bellows profile give the hose good flexibility and fatigue resistance, allowing it to easily absorb cyclic loads from various motion deformations, especially providing the ability to compensate for large displacements in piping systems.

HERION hose fitting selection

How to select high-pressure pipe fittings: 1, hose size: The inner diameter of the hose must be appropriate. If the hose is fixed with clamps or passes through spacers such as steel plates, pay attention to the outer diameter of the hose. 2, working pressure: According to the safety factor for hydraulic hoses specified in relevant international standards, the recommended working pressure is generally one quarter of the minimum burst pressure of the hose. 3, impulse pressure and fatigue life: Hose selection is determined based on the maximum pressure value of the hydraulic system design. Impulse pressure does not seriously affect the fatigue life of the hose; for hydraulic systems with particularly frequent impulse pressure, it is recommended to select hose products specially resistant to pulsating shock. 4, temperature range: Users should use hoses within the temperature range permitted by the hose quality specifications, and if operating continuously, frequent cooling is recommended. 5, chemical compatibility: If using special hydraulic media, users must ensure that the inner and outer layers of the selected hose assembly, the fittings, and the O type O-rings are compatible with the medium.

HERION hose fitting classification

Inert gas type, mainly used for vacuum piping and compressor pressure tests. Both the socket and plug have built-in automatic shut-off valves suitable for vacuum applications, maintaining a vacuum level of 1.3×10Pa in the disconnected state. Precautions for use: Do not exceed the maximum allowable working pressure during use. Do not use outside the specified temperature range to prevent wear or leakage of sealing materials. Do not manually strike, bend, or stretch to prevent damage. Do not connect or disconnect under pressure or residual pressure. Do not disassemble. Use sealant for tapered pipe threads (external thread). Do not manually strike, bend, or stretch to prevent damage. Do not use with fluids other than the specified applicable fluid. Do not use for purposes other than quick couplings. Do not connect with quick fluid couplings from other manufacturers. Do not use in environments containing metal powder or sand/dust to prevent malfunction or leakage. Attachment of debris can cause malfunction or leakage. A brake valve must be installed before the quick coupling. Do not use as a hinged joint. Use in machines with vibration or impact will reduce durability. Cold water/warm oil type, mainly used for general-purpose mold interfaces. Fully simplifies mold exchange operations, enhances rust prevention, and offers diverse types. Precautions for use: Note, do not use with fluids other than the specified applicable fluid. Do not exceed the maximum allowable working pressure during use. Do not use outside the specified temperature range to prevent wear or leakage of sealing materials. Do not manually strike, bend, or stretch to prevent damage. Do not use in environments containing metal powder or sand/dust to prevent malfunction or leakage. For threaded installations, do not exceed the maximum tightening torque to prevent damage. Do not use cracked hoses to prevent leakage or detachment. Use in machines with vibration or impact will reduce durability. The working fluid must be clean fluid filtered through a filter. Do not disassemble quick couplings. Semiconductor type, mainly used for semiconductor and fluororesin semiconductor production equipment/devices. The body material should be corrosion-resistant metal or all-resin products made from molded fluororesin (PFA). Precautions for use: Note, perform leaching tests of sealing materials with the fluid to confirm material suitability. Use Teflon sealing tape for external tapered pipe threads. Do not exceed the maximum tightening torque when installing threads to prevent damage. To reduce friction (insertion load) and protect the "O" type O-ring during insertion, apply the working fluid or pure water to the "O" type O-ring or the quick coupling (the folded part of the "O" type O-ring). During disconnection, since a small amount of fluid flows out, compressed air can be used to discharge the fluid from inside the quick coupling before separation to prevent hazards. Do not use as a hinged joint. Do not use for purposes other than quick fluid couplings. Do not manually strike, bend, or stretch to prevent damage. Do not pressurize sleeves or quick coupling bodies alone to prevent the valve from flying out. When used as a single unit, the specified dust cap must be installed. Do not disassemble quick couplings.

HERION hose fitting precautions

Open type: When the mold couplings and mold water nozzles in high-pressure water hose quick couplings are in an open state, in the disconnected condition, pushing the copper sleeve on the female head to the other end causes the steel balls to roll outward automatically, allowing the male head to be removed. In this case, since neither the male nor the female head has valves, fluid will flow out. In the connected state, the male head is inserted into the female head, and the copper sleeve is pushed back to its previous position by spring force, locking the steel balls and allowing fluid flow; the O type O-ring prevents fluid from leaking out. Combined type water quick coupling: When the mold water nozzle in the high-pressure water hose quick coupling is open and the mold coupling is in a closed state, in the disconnected condition, the copper sleeve in the female head moves to the other end, causing the stainless steel balls to roll outward automatically. The male head is opened by the reaction force of the valve spring, causing the valve to close automatically and block fluid flow. In the connected state, the male head is inserted into the female head, and the copper sleeve is pushed back to its previous position by spring force, locking the steel balls and allowing fluid flow; the O type O-ring in the high-pressure water hose quick coupling prevents fluid from leaking out.
