Hydraulic Hose, Fittings, and Flanges
Hydraulic Hose is highpressure, synthetic rubber, thermoplastic or reinforced hose that transfer fluid to transmit force within hydraulic machinery. The hydraulic machinery has been used since 1940 when engineers discovered that hydraulic systems were more compact in size, light in weight & selflubricating. The development of hydraulic hoses opened the way for a development of a wide array of brand new, highpowered machines for military applications. When it comes to the development of flexible hydraulic hoses for the development of a wide array of high powered machines that are based on hydraulic technology. Typically, Hydraulic hoses use the distribution of water in order to operate or transform a part of the machinery. The hydraulic hose fittings are connected & transmitted hydraulic power to another device. This kind of hydraulic fitting required relies on the connection source. The Hose fittings can come up with many ways, such as Oring, elbow, pipe, flanges, face seal & flare less. SAE (Society of Automated Engineers) sets the standards for all these hose fittings on the machinery. Almost each hydraulic system, the fittings joins the lengths of the pipe & hose, which run between the different parts of the system. These are hydraulic fittings must be fitted in a manner, for instance, if the pipes get damage or there is a requirement for the tubes to be replaced or repaired. As they can be omitted easily. The hydraulic fittings are categorized into two major parts: 1)AllMetal Fittings 2)ORing Fittings 3)Metal Thread Fittings 4)ORing Hydraulic Fittings
Hydraulic fittings come up in different sizes in order join hoses on the components. They deliver hydraulic fluid to them in power. There is also heavy equipment such as dump trucks & back hoses that use hydraulic energy to widen truck beds. When it comes to its measurements that needed to fit a hydraulic fitting correctly that are embraced such as exterior diameter, length, thread gauge & angle of the fitting. When the components within hydraulic systems had never to be removed. The connections could be brazed or welded in order to widen or enhance the reliability. Nevertheless, it is invariable that connections should be broken up to allow replacing components. Therefore, removable fittings are a necessity for all, but most of the specialized hydraulic systems. At the end, the fitting designs have advanced considerably to enhance performance & installation convenience, moreover, the overall function of these components that remain relatively unchanged. Within the hydraulic system, fitting seal fluid uses one of two techniques, for instance, allmetal fittings rely on metalto metal contact, whilst Oring type fittings that contain pressurized fluid by compressing an elastomeric seal.
AllMetal Fittings You may notice threads on pipe fittings that are tapered, and it may rely on the stress generated by forcing. The pipe threads are subject to leakage due to the fact that they are torquesensitive over tightening misconducts the threads so much. In addition, they are subjected to loosen when exposed to vibrations & wide temperature vibrations. The threads should be expected when pipe fittings are used in
highpressure hydraulic systems. Since, pipe threads are tapered, assemble & disassemble that only makes the leakage problem by distorting threads, especially when a forged fitting is used in the castiron port. It is highly recommended for pipe fittings that are still another reason why most of the designers believe them to be outdated for use in hydraulic systems.
FlareType Fittings: On the other side, the flare type fittings were developed as an improvement over pipe fittings before so many years. This probably remains the design used most often in the hydraulic systems. To tighten the assembly's nut that draws the fitting into the flared tube face & fitting body. 37° flare fittings are designed for the usage of with thinwall to medium thickness tubing in the systems. It is worked between the temperature range 65° to 400° F. For forged components manufacturer, this is something more than most of other fittings, and it can easily be adapted to metric tubing. This is readily available, plus one of the most economical. The flare less fittings are gaining wider acceptance in the United States. This is due to the reason that they need minimal tube preparation. Also, it handles average fluid working pressures, it is more tolerant of vibrations as compared to all metalfittings. At long lost, the flare less fittings should be used with medium or thickwalled tubing.
Flareless: The flareless fittings need less tube preparation, and can handle an average of 3,000 psi. It includes a ferrule body, which tightens onto the nuts of fittings.
Elbow: This kind of fitting comes up with several sizes, i.e. 45º for both male & female, plus 37º and 90º.
Flanges: These are for tube fittings that are larger than (> 1 inch) one inch in size.
Oring Type Fitting It may surprise you that leakage in hydraulic systems that could have been omitted more than a generation ago. However, the leakfree hydraulic operations had always been desirable. This need has become acuter with highest operating pressures, which became necessary. With highest hydraulic fluid leakage has brought up by higher pressure. It is worked up under the umbrella of the committee of tubing, piping of SAE. Fittings that use Orings for tight connections that continue to gain the acceptance by equipment designers around the worldwide. In precision machined components manufacturers, there are three basic types that are available such as: • • •
Oring Flange Fittings Oring Boss Fittings Face Seal Or Flat Face Oring (FFOR) Fittings
When it comes to a choice between FFOR fittings or Oring boss, it usually depends on such factors wrench clearance, fitting location or individual preference. The flange connections usually used with tubing, which has an OD (Outer Diameter) greater than 7 to 8 inches, or the applications are involved extremely high pressures. Generally, Oring boss fittings fall into two groups, i.e., adjustable and nonadjustable. The nonadjustable fitting includes connectors & plugs. All these are simply screwed into the port, and there is no alignment is needed. When it comes to adjustable boss fittings, then it includes elbows & tees, and needs to be oriented in a specific direction. The fundamental difference between two is that the plugs & connectors have zero lock nuts, it also requires no backup washer to effectively a joint.
Metal Thread Fittings These fittings make use of meshing threads of two parts of the pipes to seal the joints for pressurized hydraulic fluid. The hydraulic joints are acceptable absolute perfect conditions. These sorts of metal fittings are less reliable for usage as they are vulnerable to vibration & temperature shock damage.
