Legris hose connector Germany Legris model Legris price

Legris hose connectors are end-type straight fittings 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 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 pipeline. The bellows of the hose are formed by high-precision plastic working 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, making it easy to absorb cyclic loads from various motion deformations, especially providing the ability to compensate for large displacements in piping systems.

Legris hose connector cleaning

To ensure the cleanliness of the lubrication system and supply clean grease to the bearings of mechanical equipment, the pre-installed piping must be removed and cleaned. Cleaning methods include kerosene cleaning and pickling. Objects and methods for kerosene cleaning: copper pipes, stainless steel pipes; steel pipes that have been pickled before pre-installation and have no rust or iron oxide scale on the inner wall; pipe connectors contaminated during pre-assembly. Remove the pipes and connectors to be cleaned, wipe the inside of the pipes clean with a cloth soaked in kerosene, soak the ends and connectors in kerosene for cleaning, then coat the inside with machine oil or fill with grease, and seal both ends tightly for installation. There must be no visually visible contaminants after cleaning; special attention must be paid to thoroughly cleaning the weld slag on the inner wall of welded joints. During disassembly, transportation, and pickling, take care not to damage the piping, threads, and sealing surfaces, and use tape or plastic tubes to block the openings. Threaded parts should be protected with acid-resistant materials such as plastic tape or rubber tape, or coated with dry oil after degreasing and water washing before rust removal in acid solution to prevent acid erosion. During pickling, take care not to erase or blur the matching marks on the pipes.

Legris hose connector installation

1. Clean impurities. When installing water pipe connectors, thoroughly remove all impurities from the pipeline to avoid valve core damage, jamming, blockage, and leakage. Also, clean the surface to leave no residual building materials. 2. Do not apply excessive force when switching. For any type of household water pipe connector product, no excessive force is required when switching; just gently turn or move it. Even for traditional household water pipe connectors, there is no need to exert great effort to tighten them completely. In particular, do not use the handle as a support or handrail. For products with screen covers at the water outlet, disassemble and rinse after a period of use to remove impurities. 3. Pay attention to regular cleaning. Household water pipe connectors that are not used for a long time may sometimes fail to close completely, leak, have loose handles, or have loose connections causing leaks. In most cases, consumers can resolve these issues themselves. 4. Keep household water pipe connectors extended. The metal hose of the shower head for household water pipe connectors should remain in a naturally extended state; do not coil it around the faucet when not in use. At the same time, whether in use or not, ensure that the joint between the hose and the valve body does not form a dead angle to prevent breaking or damaging the hose.

Legris hose connector applications

Hose connectors mainly include threaded connections, flange connections, quick couplings, and other types. Different types have different applications. The main components of metal hoses are made of austenitic stainless steel, ensuring excellent temperature resistance and corrosion resistance. There are many models of metal hose connectors, and specifications are mainly selected based on the inner diameter. For metal hose connector models, the main difference lies in the meaning of some threads, such as the common NPT, PT, G, etc. These have different meanings, and consumers should understand what these connectors represent before purchasing according to their needs. Different models correspond to different connectors. In fact, metal hose connector models correspond to metal hoses, so attention should be paid to certain aspects during selection. First is the choice of connector type, which generally includes flange connections, threaded connections, and quick couplings, selected according to actual needs. The second aspect is pressure; collection and distribution hoses and connectors should be selected based on the actual working pressure to ensure smooth operation. Other factors include the pressure and temperature the metal pipe connector can withstand, and the corrosiveness of the medium.
