How to Choose Hydraulic Fittings?Posted on March 27th, 2023
Hydraulic fittings can be considered as the parts utilised for connecting tubes, pipes and hoses in hydraulic systems. The equipment for hydraulic purposes operates under tremendous pressure, and it is not a fixed system. The fittings must be versatile, strong and sturdy enough to operate effectively and safely in particular applications. They are according to the street guidance, which indicates dimensions, construction and pressure ratings.
Hydraulic Systems: Hoses, Pipes, and Tubes
It is essential to keep a few things in mind when it comes to hydraulic systems for understanding the best kind of fittings.
- Hydraulic pipes refer to bigger diameter hydraulic tubes and are utilised for low-pressure work or when there are no hydraulic tubes. They are connected by threaded connections or welding. Due to bigger diameters, the pipe can be internally inspected after welding.
- Hydraulic tubes refer to seamless pipes particularly manufactured for the hydraulic system. They come with standard dimensions for multiple pressure ranges having diameters up to 100 mm. The length of the tubes is connected through flanges, flare connections, welding nipples or cut rings. Joining the tubes directly through welding may not be acceptable because one cannot inspect the interior.
- When it comes to hydraulic hoses, they are generally graded by temperature, pressure and fluid compatibility. They are used in multiple applications where tubes and pipes cannot be used. They offer flexibility for maintenance and machine operation. It also contains many layers of Steel wire and rubber. One of the finest things about this element is that they have Steel fittings and a connection to the fitting. It is one of the reasons why accurate installation and proper selection are necessary for high-pressure applications.
Picking the Right Hydraulic Fittings
If you need help with what threading material and shape option to pick for the fittings, the following guide can help you choose the particular hydraulic fittings for the hydraulic system.
- When choosing fittings, refer to the application, temperature, size, pressure and media and choose the perfect fitting.
- Ensure to measure the temperature rating to not exceed the ambient temperature and highest media of the application. The operating temperature range depends on the seal type, plating and material. Make sure to utilise materials that assure leak-free operations.
- The environment of operation of your hydraulic system is an essential factor to keep in mind. Choose fittings that will meet the application’s legal demand and functional features. Consider the aberration and mechanical loads that apply to the entire fitting assembly.
- The kind of fluid that comes in contact with the fitting or is conveyed through the hose is also an essential factor. The tube and hose must be compatible with mediums because measuring. The compatibility before can help you get the right fitting.
- Make sure to choose the perfect material for your hydraulic fitting because every material has unique properties. So choose the right material accordingly.
- Pick the type of fittings according to the crimp fitting because they are one of the most popular. All connections will be necessary to help direct and contain the liquids in the hydraulic system, prevent leaks, and maintain pressure.
- After you have chosen the particular specification and fittings, call a professional to help you assemble the fittings in the hydraulic system. It is essential to remember that you must never combine a fitting of one manufacturer with another because it can lead to rupture or failure of the system due to incompatibility.
- Ensure the tube’s diameter and the wall’s thickness, essential to ensure accurate flow velocity. Slow flow results in sluggish hydraulic systems and damages performance; extremely high flow causes pressure drops.
- There are multiple established manufacturers available for fittings, and you need to do detailed research before you pick from the inventory of hydraulic materials for a reliable solution. You need to ensure that your connection is leak proof and that sufficient flow and ambient temperature are maintained in the system. So, please choose the appropriate materials accordingly so that it does not damage the application, features and the entire hydraulic system.
You need to know these things before choosing fittings for your hydraulic system. Consider many things before you choose the best quality material. This guide can be helpful for you so that you pick the right material and meet the demands and specifications of the entire system so that everything is fine later.
