NORDS hose fittings Germany NORDS model NORDS price

NORDS hose fittings are connecting devices used to join metal hoses and pipes. Their models are typically determined by factors such as material, connection method, size, and applicable working pressure. Different models have different characteristics and scopes of application, such as ferrule-type metal hose fittings, flange-type metal hose fittings, and swivel-type metal hose fittings. Selecting the appropriate metal hose fitting model requires consideration of multiple factors, such as the temperature, pressure, fluid medium, service life, and connection method of the working environment. For applications under special conditions such as high temperature, high pressure, and strong corrosion, it is necessary to select high-quality metal hose fitting models that can meet the requirements.

NORDS hose fitting selection criteria

1, type of fluid, and temperature (please select quick couplings with body and sealing materials suitable for the fluid type and temperature). The suitable body and sealing materials vary depending on the fluid. For example, for air, steel quick couplings are recommended; for water, brass or stainless steel ones should be selected. 2, liquid pressure (please select quick couplings with pressure resistance suitable for the fluid pressure). Fluid pressure is also a key factor in selecting quick couplings. Quick couplings for hydraulic oil form a series between 5.0Mpa (51kgf/cm&²) and 68.6Mpa (700kgf/cm&²), and their construction varies according to pressure resistance characteristics. 3, automatic shut-off valve construction (please select quick couplings with valve construction suitable for piping applications). Valve constructions include two-way shut-off, one-way shut-off, and two-way open types. Please note that, except for the two-way shut-off type, fluid will flow out from the piping upon disconnection. 4, usage environment of the quick coupling (please select the construction and material of the quick coupling suitable for the usage environment). Consider the humidity, dust conditions, and corrosiveness of the environment when selecting the type of quick coupling, body material, and sealing material. 5, ensure that the connection threads of the selected quick coupling are consistent. When using products from different brands, it is best to use male and female connectors from the same brand. If cross-brand usage is necessary, consult the supplier's technical personnel before use to confirm compatibility. 6, installation shape and dimensions. Determine the model and material of the quick coupling, and specify the assembly shape and dimensions corresponding to the piping characteristics. Note that dimensions are related to fluid flow rate.

NORDS hose fitting cleaning

To ensure the cleanliness of the lubrication system and supply clean grease to the bearings of mechanical equipment, pre-installed pipelines must be removed and cleaned. Cleaning methods include kerosene cleaning and acid pickling. Objects and methods for kerosene cleaning: copper pipes, stainless steel pipes; steel pipes that have been acid-pickled before pre-installation and have no rust or iron oxide scale on the inner wall; pipe joints contaminated during pre-assembly. Remove the pipes and joints to be cleaned. Wipe the inside of the pipes clean with a cloth soaked in kerosene. Soak both ends and the joints in kerosene for cleaning. Then apply machine oil or fill with grease inside the pipes, and seal both ends tightly for installation. There must be no visually visible contaminants after cleaning. Pay special attention to thoroughly cleaning the weld slag on the inner wall at welded joints. During disassembly, transportation, and acid pickling, take care not to damage the pipelines, threads, and sealing surfaces. Use tape or plastic tubes to seal the openings. Protect threaded parts with acid-resistant materials such as plastic tape or rubber tape, or apply dry oil to the threads after degreasing and water rinsing before rust removal in acid solution to prevent acid erosion. During acid pickling, ensure that the matching marks on the pipes do not disappear or become blurred.

NORDS hose fitting precautions

When installing water pipe fittings, thoroughly remove all impurities from the pipeline to avoid valve core damage, jamming, blockage, and leakage. Also, clean the surface to ensure no residual building materials remain. For any type of household water pipe fitting, excessive force is not required during operation; simply turn or switch gently. Even with traditional household water pipe fittings, there is no need to exert great force to tighten them completely. In particular, do not use the handle as a support or handrail. For products equipped with screen filters at the water outlet, disassemble and rinse them after a period of use to remove impurities. For products with hoses, ensure the hoses remain in a naturally extended state to prevent breakage.
