Taconova hose fittings Germany Taconova model Taconova price

Taconova hose fittings connect different hydraulic components (pumps, delivery lines, directional valves, shut-off valves, hydraulic motors, hydraulic cylinders, and some auxiliary components, such as level gauges, thermometers, pressure gauges, etc.) to form a closed-loop hydraulic system. Hydraulic pipe fittings are accessories that serve a connecting role in this process. Hydraulic pipe fittings are detachable connectors between oil pipes and oil pipes, or between oil pipes and hydraulic components. They should meet requirements such as easy assembly and disassembly, reliable connection, reliable sealing, small external dimensions, high oil flow capacity, low pressure loss, and good manufacturability. Hydraulic pipe fittings are widely used in various aspects of our lives. They are mainly used in hydraulic piping systems in industries such as energy, petrochemicals, electric power, ships, automobiles, rail transit, mining, metallurgy, steel plants, marine engineering, and construction machinery. Construction machinery is where hydraulic pipe fittings are most frequently used.

Taconova hose fitting selection

What are the materials for hydraulic pipe fittings? Ordinary hydraulic oil is not corrosive to steel pipes and steel fittings, so carbon steel fittings are commonly used in hydraulic systems. Pipelines connected to drinking water or pure water should not use ordinary carbon steel. Previously, compressed air regulations required the use of brass pipes because compressed air would carry moisture that accumulates inside the pipes; if carbon steel pipes were used, the pipelines would corrode. Advanced air compression machinery no longer produces moisture, so this regulation has lost its significance. Chemical equipment pipelines usually transport various corrosive fluids and require frequent flushing with solvents or water. Therefore, ordinary chemical pipelines must be made of stainless steel. When considering the corrosiveness of the medium, the relationship between the pipeline seals and the medium should be primarily considered. Nitrile rubber (HEPG) is widely used in hydraulic systems because it is compatible with ordinary hydraulic oils. At certain temperatures, nitrile rubber (HEPG) is also compatible with synthetic acetaldehyde, glycol-based chemical liquids, and plant-derived liquids. However, nitrile rubber (NBR) is not suitable for contact with acidic media, benzene, or synthetic oils at high temperatures; in these cases, fluorocarbon rubber (FKM) should be used. Conversely, methane and refrigeration ammonia are only compatible with nitrile rubber (NBR), so most chemical stainless steel pipelines use rigid seals. To select pipe fittings, one must know the nominal pressure of the fitting. Nominal pressure is a standard parameter and is numerically equal to the maximum working pressure of the system. The maximum working pressure must satisfy a static safety factor of 4 times and a dynamic safety factor of 1.33 times, i.e., the burst pressure determined by burst testing divided by 4, and the maximum pulse pressure divided by 1.33; the smaller of the two values is defined as the maximum working pressure. 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's operating state. One must consider not only the pump outlet pressure but also the relief valve cracking pressure. Therefore, when designing complex hydraulic pipelines, it is best to determine the actual pressure through on-site measurement. Once the system working pressure is determined, the maximum working pressure of each selected pipe fitting must be checked. The maximum working pressure of a pipe fitting can vary depending on the sealing method or temperature changes: the same pipe fitting will achieve a higher working pressure with elastic sealing than with rigid sealing.

Taconova hose fitting precautions

1. Before cleaning pipes with acidic detergents, residual welding slag, stains, varnish, and other substances must be cleaned off to prevent chemical reactions that could cause unnecessary damage to the pipes and affect future use. 2. To ensure the normal use of hose fittings, they must be specially protected. During transportation, disassembly, or pickling, care must be taken not to damage threads, pipelines, and sealing surfaces. The best method is to seal them with tape. 3. For all threaded parts of the hose fittings, acid-resistant plastic tape or rubber tape should be used for protection. Alternatively, after direct water washing, apply dry oil to the threaded areas, let it dry completely, and then immerse in acid solution to remove rust spots. 4. During the pipe cleaning process, special attention must be paid to the markings on the pipes to protect their integrity as much as possible. Welding tasks must be completed before pickling. In daily life, necessary protection measures for hoses must also be observed.
