Stainless Steel Instrumentation Tube Fittings offer torque-free, leak-proof sealing for all tube connections. They guard against potentially harmful and expensive leaks in gas, pneumatic, hydraulic, instrumentation, process, and other tube structures. Numerous applications requiring the highest degree of product consistency have led to the construction of instrumentation fittings.
A nut, a back ferrule, a front ferrule, and a body are added to the basic stainless steel 316 instrumentation tube fittings to create a five-piece connection that ensures a strong, leak-proof connection. Without damaging the tube’s surface, the two ferrules hold it in place. The tube will give before the Double-Ferrule junction leaks, according to extensive research.
The Double-Ferrule Tube Fitting’s effectiveness is due to its two-ferrule configuration, which incorporates geometry and metallurgy. All of the fitting’s activity is an axial movement along the tube rather than a rotational motion that creates the joint. The tube is not subjected to any torque because of this axial movement. The dual ferrule’s swaging motion adjusts for variations in the thickness, hardness, and dimensional tolerance of the tubing wall, which is another advantage of the SS Tube Fitting.
Both single- and double-ferrule tube fittings are easy to assemble and don’t require any specialised equipment. In vacuum and pressure systems, these can withstand intense pulses and vibrations and are reusable. Choosing the right tube for the job is one of the first stages in creating an instrumentation system that doesn’t leak. Without this crucial element and its interoperability with the others, no system can be considered fully intact. When choosing a standard instrument tube for use with tube fittings, there are four important factors to take into account, which we will discuss in this piece.
Stainless steel instrumentation fittings’ characteristics
Self-alignment
Work on both thin and thick-walled tubes.
Vibration resistance
There are several tube materials under development.
Every component is made of the same material for corrosion resistance and heat stability.
Variable temperature resistance
Tube and material variations are corrected for.
Limit the flow area as much as you can.
The functionality of instrument fittings made of stainless steel
Work in vacuums and at both high and low pressures.
Both the tube’s maximum operating temperature and low cryogenic temperatures should be sealed.
The seal holds constant throughout a broad variety of temperature cycles.
Seal frequently under both create and recreate conditions.
Continue to apply pressure until the tube explodes.
Stainless steel instrumentation fitting applications
Stainless steel-based instruments Oil and gas installations, steam and gas turbines, aerospace, defence, power generation, petrochemicals, alternative fuels, shipbuilding, medical equipment and chemical processing are just a few of the applications for tube fittings.
Hydraulic fittings used in the chemical processing and oil and gas sectors need to be designed to survive challenging conditions. Applications for stainless steel fittings and valves are numerous, ranging from refineries and the processing of caustic chemicals to salt spray on North Sea offshore rigs.
The most widely used types of stainless steel instrumentation fittings are SS 304 and SS 316, however they are available in a range of shapes and strengths.
When Choosing Instrumentation Tube Fittings Made of Stainless Steel
Material for Tubing
When selecting the right material for tube fittings, take into account the operating conditions, including temperature, pressure, and media. Such tubing’s expected lifespan, cost, and suitability for the environment must all be taken into account. Most industries should employ materials that are resistant to corrosion. The most often used materials are stainless steel, carbon steel, and copper tube. This is one of the recommended materials since the tube will be extremely resistant to corrosion.
Hardness of Tubing
Compared to the materials used in the fittings, the tubing should be softer. Nevertheless, a certain tube hardness needs to be attained for leak-free connections. There are several hardness standards for stainless steel tubes that work well in different circumstances. Every one of our tubings has undergone extensive testing to ensure optimal performance and the lowest possible installation costs. A 1-1/4 rotation should be performed by installers to ensure flawless joins. This is particularly true when using a more torqued, harder tube. Stainless steel tube, for instance, need to have a hardness rating of Rb 80 or lower.
Wall Thickness of Tubing
There are several wall thicknesses for these tubings. Their pressure ratings show which applications they are suitable for. Usually, thickness falls between 0.028 and 0.109 inches. These wall thicknesses are recommended for tubes up to 1 inch in diameter. It is possible to raise the wall thickness of larger tubes, which can vary from 0.125 to 0.167 inches.
Surface Coating for Tubing
A range of surface coatings are available, depending on the application’s requirements. For instance, corrosion-resistant coatings are commonly applied to metal tubings, particularly in settings where these kinds of reactions are prevalent. The best option is still stainless steel 316 instrumentation tube fittings.
