What is Press Fitting?
Press fittings are mechanical connectors used in plumbing and piping systems to join pipes and fittings together without welding or soldering. They are very common and useful in compressed air systems. They offer a secure, reliable, and convenient alternative to traditional joining methods.
Top 5 Reasons To Use Press Fittings
1. Press fittings save time and money.
With press fittings, connections can be made in a fraction of the time that it takes to weld or solder pipe. Plus, significantly less training is required to operate the press tool compared to welding, brazing or soldering. This makes press fittings an excellent labor saving solution, especially when installing large-scale pipe systems.
2. Press fitting connections are secure.
Press tool operations vary by brand, but one thing that is consistent is the strength of connections. As long as the pipe is prepared correctly according to the press tool system manufacturer instructions, the connection is as strong as a welded or soldered connection.
Many hydraulic press tools have an auto-cycle feature that only shuts off when the connection is complete, so there is no guessing if pipe is fully joined or not.
3. Jobsite safety is improved with press fittings.
Caution and safety should always be paramount on the jobsite. Press fittings offer additional safety because there is no heat or flame required to make connections. This reduces the risk of worker injury on the job. Less safety gear is required to operate a press tool compared to welding or soldering, which can provide additional cost savings.
4. Press fittings are dynamic.
Because press fittings are available in copper, stainless steel and carbon steel, they work with virtually any pipe system made of those materials. This makes them suitable for use in a variety of applications. From gas, petroleum and corrosives to steam and potable water, it’s likely that there is an appropriate press fitting solution for your project.
5. Repairs can be made quickly with press fittings.
Even if the pipe system is wet, press fitting connections can still be completed. This makes press fittings well suited for use in commercial and industrial facilities because operations won’t be interrupted if repairs need to be made. Press fittings eliminate the need to shut down a pipe system to perform maintenance.
Material of Press Fitting
Stainless steel press fittings
SS press fittings is main applied to potable water system. Stainless steel has been used widely in developed countries due to it’s health and safety. Such as hospital, school, hotel and so on.
Copper press fittings
Copper press fitting can be used for a variety of applications including potable water, heating, gas, cooling&refrigeration, industry, offshore, solar system and saturated steam. But it is only used widely in developed countries due to the high cost.
Carbon steel and galvanized steel press fittings
Carbon steel and galvanized steel press fittings are main applied to these area that do not require stainless steel. Includes oil and diesel lines, compressed air and inert gas systems, closed-circuit heating. Carbon steel and galvanized steel press fittings can be used widely due to the lower cost.
Copper-nickel alloy press fittings
Copper-nickel alloy press fitting is applied to ship building industry due to it’s good corrosion resistance. It is made of copper/nickel 90/10 CuNi10Fe1.6Mn alloy. Max working pressure 16 bar.
Top 6 Applications of Press Fittings
Chemical Lines
The inox fittings are chemically resistant, said plumbers, allowing any industry to benefit from it. Press-fits that get approved for pipe systems applications might carry high corrosive chemicals like phosphoric and nitric acids. And, as there is no flame to make a secure connection between joints, the danger is highly reduced and excluded.
Gas Lines
Press fitting is an ideal choice to make use of gas lines and compressed air systems worthy. With the press-fit technique’s help, the gas lines can quickly be installed in any of the substances, including stainless steel, carbon steel, and copper press-fitting. When installed correctly, press-fitting yields an airtight pipe connection and appropriate sealing.
Greywater Lines
To manufacture a secure drainage system, you can have press-fitting as a life-saver at your side. It could be an excellent solution, which has vast applications in greywater lines due to its efficiency. Moreover, while installations, time is crucial to saving to make complete repairs and connections in wet conditions.
Hydronic Heating and Cooling Systems
Investing in press-fitting will ultimately pay you off when it comes to hydrogenic systems. But, select one that can be used in conjunction with chilled water and hydrogenic heat applications because this system is highly resistant to ethylene glycol and propylene glycol chemicals.
Portable Water System
National Sanitation Foundation has offered the certified yet lead-free copper and SS fitting to use specifically in the portable water system. Whether in residential new construction building projects or large-scale commercial applications, press fittings make it easier to install both the hot and cold lines for contractors.
Fuels, Oil, and Lubricant Lines
For keeping industrial operations running, well-oiled machines are required, which you can have with press-fitting for pipe connections. The press-fit technique offers safety while used with combustible substances from fuels like butane, kerosene, propane, and diesel to petroleum-based lubricants and oils.
Press fitting installation
Here's a guide on how to connect press fittings to a tube or pipe:
Cut the pipe: Use a pipe cutter to cut the tube square. Ensure the tube ends are clean and undamaged, as they will fit inside the press fitting.
Remove burrs: Use a deburring tool to remove any burrs or sharp edges from the internal and external ends of the tube. Wipe the tube ends clean to prevent damage to the sealing ring during insertion into the fitting.
Sealing ring seating and lubrication: Ensure the sealing ring is correctly seated, undamaged, and lubricated before inserting the tube. Use a small amount of water for lubrication if needed.
Mark the insertion depth: To achieve a perfect joint, insert the tube into the fitting until it reaches the tube stop (the point within a press fitting where the tube or pipe being inserted comes to a stop). Mark the tube's insertion depth to detect if there is any movement during subsequent pressing operations. Press the fitting only when the tube reaches the tube stop and the previously marked area realigns with the fitting.
Complete the joint:
1. Select the appropriate-sized jaw for the press fitting and attach it securely to the pressing tool. Position the jaws squarely over the fitting.
2. Depress the trigger or handle of the pressing tool to initiate the pressing process. Apply steady pressure until the jaws fully enclose the mouth of the fitting and the pressing tool indicates completion.
3. Once the pressing cycle is complete, release the pressing tool from the fitting. Ensure the jaws disengage smoothly without disturbing the joint.
4. Visually inspect the press fitting joint to ensure it is properly formed, secure, and leak-free. Check for any signs of misalignment or damage.
