Factors to Consider When Selecting Hydraulic Steel Tubing
Seamless precision hydraulic steel tubing should be constructed with seamless steel.
High-performing hydraulic steel should also be long-lasting in order to be suited for agricultural machinery and machine tools.
This has been used for a variety of applications, including to replace machined bar in metal fittings and letting higher pressures in assemblies.
Some of the properties of high-quality steel to look for include strength, formability, and consistency.
With these properties, the tube can be used in places where high-strength low-alloy tubing is generally needed.
Below are the factors to consider when selecting the best fitting for an application.
These factors are commonly abbreviated as STAMP to denote
Size of the tube,
Temperature the material can withstand,
Using this acronym is recommended because it acts as a primary tool to help determine the proper material and fitting for a given application.
Size: This refers to the wall thickness and outer diameter of the tube. The thickness of the wall can impose some limitations. For instance, there is a maximum wall limitation on some flare type fittings whereas flareless bite-type fittings feature a minimum wall limitation. The size is also determined by system temperature, flow, pressure, as well as the service environment.
Temperature: This is another important component of hydraulic steel tubing, as the tube has to withstand the temperature of the environment in which it operates. However, the ability to withstand the system temperature within the environment depends on factors such as the material type, seal material, and protective coating/ plating.
Application: This is ideally how the tube will be used. The application also means the system environment, which is characterised by pressure spikes, vibration, as well as mechanical load and external thermal. All these factors influence the fitting material selection, including whether or not a protective coating/ plating will be required. Therefore, the system environment under which the tube will operate determines the type of tubing to use.
Media: This is simply the type of liquid or fluid to be conveyed from one point to another through the tubing. It affects the type of tubing to be used, including the seal material.
Pressure: This also relates to the environment under which the hydraulic steel tubing will operate. The fitting’s rated dynamic pressure needs to be greater than or equal to the system pressure. A design factor is used to rate various types of system pressure.
However, it is not easy to know all these at once, especially if you are new to the world of hydraulic fittings. This is why it is often recommended to work with an engineer or technician to help you select the best hydraulic steel tubing for your application.
Whether you are in Essex, Kent, Heathrow, or London, you can find a reputable supplier who is known for supplying high-quality fittings so that you can get the best replacement parts for your hydraulic machinery or equipment. Regardless, you should have a basic idea of what you intend to use it for before making your selection, but the STAMP acronym provides a great start.
