Installing a slip-on flange involves a straightforward process. Carefully slide the flange onto the pipeline. Do this without pressing too firmly against the flange face.
This post will help give you more information about this task. Here we will provide you with a step-by-step procedure on how you can install a slip-on flange and experience its leak-free offering.
This is a popular flange type that you can slide over the end of a pipe. The slip-on flange dimensions are slightly smaller than the flange’s bore. These flanges are secured to the pipe through one or two fillet welds.
Here’s a step-by-step guide for a secure and leak-proof connection.
Make sure that both the pipe end and the inner surface of the slip-on flange are clean. Remove any debris, rust, or contaminants. Inspect the pipe and flange for any signs of damage or imperfections. They will affect the integrity of the connection.
Accurately measure the pipe to determine where to position the slip-on flange. Cut the pipe to the desired length, ensuring that the cut is clean and square. This step is important. An uneven cut leads to misalignment and potential leaks.
Once the pipe is prepared, slide the slip-on flange over the pipe end. Ensure that the pipe extends slightly beyond the face of the flange, typically about 1/4 inch. This allows for proper positioning and space for the fillet weld.
Align it with the adjacent flange or equipment to which it will be connected. Use clamps or temporary tack welds to hold the flange in place while you verify the alignment.
Proper alignment is critical. This practice will lead to a leak-proof connection. It even prevents any stress on the pipe or flange during operation.
With the flange aligned, proceed to weld the flange to the pipe. Start by performing a tack weld at several points around the flange to hold it in place. Then, complete the weld by applying a fillet weld around the outer circumference of the flange where it meets the pipe. If additional strength is required, you can also apply an inner fillet weld. Ensure that the weld is smooth and free of defects. This is to prevent leaks and maintain the integrity of the connection.
After welding, allow the weld to cool before proceeding to the bolting stage. Align the bolt holes of the slip-on flange with those of the adjoining flange or equipment. Insert the bolts and tighten them in a star pattern to ensure an even distribution of pressure. This helps prevent warping of the flange and ensures a secure, leak-proof connection.
Slip-on flanges applications cover a wide range of piping systems. Below is a list of slip-on flange uses in different industries:
Slip-on flanges are ideal where the pressure typically does not exceed 300 psi. They are used in water and gas pipelines. As well as cooling water lines, firefighting water lines, and low-pressure compressed airlines. The ease of installation and cost-effectiveness make them a preferred choice in these settings.
Slip-on flanges are used to connect piping systems and equipment. Their ability to handle corrosive substances and maintain a secure connection makes them suitable for these environments. In which reliable performance is crucial.
They are widely used in HVAC (Heating, Ventilation, and Air Conditioning) systems. They connect ductwork and piping. They ensure a secure and efficient flow of air, steam, and other fluids within the system. They are a popular choice in both residential and industrial HVAC systems because of their versatility and ease of installation.
They are essential for connecting various piping systems and equipment. Their ability to handle varying pressures and temperatures makes them ideal for use in systems that process and treat water for various uses.
Slip-on flanges are extensively used where hygiene and safety are paramount. They connect piping systems that transport fluids and gases within processing plants. They ensure a secure and sanitary operation.
