herbert haenchen hose fittings are translated from the English word bushing, professionally known as reducing fittings. They are generally manufactured by cutting and forging hexagonal bars, with various thread types available. They connect internal and external threaded pipe fittings for two pipes with different diameters and play an irreplaceable role in pipe connections.

herbert haenchen hose fitting crimping

How to crimp high-pressure hose fittings: first is the international metric internal thread flat-face fitting, second is the international metric bite-type fitting, third is the international metric internal thread 74 degree internal cone face fitting, fourth is the international metric internal thread spherical fitting, fifth is the mining hydraulic support fitting. Precautions for using high-pressure oil hose fittings: 1. When handling high-pressure oil hoses, ensure no surface friction occurs to prevent damage. Although the hose is designed for use, surface leakage must be avoided. 2. Do not bend high-pressure oil hoses, as this causes internal damage and creates unnecessary trouble for future use. 3. Do not put high-pressure oil hoses into immediate use; it is recommended to filter them with water first. Some high-pressure oil hoses are acid and alkali resistant; do not use testing liquids that conflict with the current fluid. 4. Tighten high-pressure oil hose fittings securely during installation to prevent fluid leakage.

herbert haenchen hose fitting cleaning

To ensure the cleanliness of the lubrication system and supply clean grease to mechanical equipment bearings, pre-installed pipelines must be disassembled and cleaned. Cleaning methods include kerosene cleaning and pickling. Kerosene cleaning objects and methods: copper pipes, stainless steel pipes; steel pipes that have been pickled before pre-installation with no rust or iron oxide scale on the inner wall; pipe fittings contaminated during pre-assembly. Disassemble the pipes and fittings to be cleaned; wipe the inside of the pipes clean with a cloth soaked in kerosene, soak both ends and fittings in kerosene for cleaning, then coat the inside with engine oil or fill with grease, and seal both ends tightly for installation. No visible contaminants should remain after cleaning; pay special attention to thoroughly cleaning weld slag on the inner walls of welded joints. During disassembly, transportation, and pickling, avoid damaging pipelines, threads, and sealing surfaces; seal openings with tape or plastic tubes. Protect threaded parts with acid-resistant materials such as plastic or rubber tapes, or apply dry oil to threads after degreasing and water washing before rust removal in acid solution to prevent acid erosion. During pickling, ensure that matching marks on the pipes do not disappear or become blurred.

herbert haenchen hose fitting principle

Quick-change fittings come in two types: one with a check valve and one without. For applications with a check valve, the check valve end connects to the air source. When disconnected, the check valve closes automatically; when connected, the moving end's pin opens the check valve. Self-locking is achieved by embedding steel balls into grooves, while a 'cone-cylinder' sleeve locks the steel balls in place.
