HONLE hose fittings Germany HONLE model HONLE price

HONLE hose fittings are straight-through connectors used for linear connections such as instruments. Connection methods include socket welding or threaded connection. They are mainly used for small-diameter low-pressure pipelines, for parts that require frequent assembly and disassembly, or for final adjustment of pipelines using threaded fittings. Relevant products are all recorded by Kuaiyiyou. The structural form should preferably adopt a metal-to-metal contact sealing structure. Gasket sealing structures are generally used in general pipelines transporting water, oil, air, etc., and are made of malleable cast iron. In addition, application requirements and quotation are also factors to consider when selecting. Straight-through hose fittings have a wide variety of types. Commonly used straight-through hose fittings can generally be divided into two types: hard hose straight-through fittings and soft hose straight-through fittings. If classified according to the connection method between the straight-through hose fitting and the pipeline, hard hose straight-through fittings come in three types: flared, ferrule-type, and welded. Soft hose straight-through fittings are mainly crimped rubber hose straight-through fittings. The connection methods between pipelines and straight-through hose fittings in hydraulic systems also differ; the pipe insertion end uses connecting threads. Tapered threads rely on their tapered body to tighten and use materials such as polytetrafluoroethylene for sealing operations, and are mainly used in medium and low-pressure hydraulic systems.

HONLE hose fitting features

Insert the steel pipe into the ferrule and tighten it with the ferrule nut. The friction of the ferrule cuts into the pipe to create a seal. It does not require welding when connecting to steel pipes, which is beneficial for fire prevention, explosion protection, and high-altitude work, and can eliminate the drawbacks of careless welding. The mechanical advantages and geometry of the fitting make this mechanical device a sealing component capable of preventing leaks. The mechanical thrust pushes the rear ferrule against the conical back of the front ferrule, while simultaneously pushing the front ferrule into the conical reducing mouth of the fitting body. The ferrule is squeezed onto the conduit by an inward radial force. At this point, pulling out the front ferrule forms a full-face seal on the conical reducing surface of the fitting body. When hand-tightening feels secure, rotate the ferrule nut further from this manually tightened position to ensure uniform thrust on the seal. This ensures effective sealing performance even in high-pressure and ultra-high vacuum environments. Therefore, it is a relatively advanced connector in the piping of automatic control devices in systems such as oil refining, chemical industry, petroleum, natural gas, food, pharmaceuticals, and instrumentation.

Chemical equipment pipelines usually transport various corrosive fluids and require frequent flushing with solvents or water. When considering the corrosiveness of the medium, the relationship between the pipeline seals and the medium should be primarily considered. Nitrile rubber is widely used in hydraulic systems because it is compatible with common hydraulic oils. At certain temperatures, nitrile rubber is also compatible with synthetic acetaldehyde, glycol-based chemical liquids, and plant-derived liquids. However, nitrile rubber is not suitable for contact with acidic media, benzene, or synthetic oils at high temperatures; in these cases, fluorocarbon rubber should be used. Conversely, methane and refrigerant ammonia are only compatible with nitrile rubber. Therefore, most chemical stainless steel pipelines use rigid seals. When selecting pipe fittings, the maximum working pressure of each fitting must be at least equal to the maximum set working pressure of the entire hydraulic system. One must consider not only the pump outlet pressure but also the relief valve cracking pressure. The maximum working pressure of hydraulic pipe fittings may vary depending on the sealing method or temperature changes: similarly, selecting elastic seals for fittings will yield higher working pressures than rigid seals.
