Flanges are an integral component in many industrial applications, especially in the construction, petrochemical, and oilfield industries. They are used to connect pipes, valves, pumps, and other equipment in a piping system. A flange provides a secure and leak-proof joint, which is critical in applications where fluids or gases are transported at high pressures or temperatures.
For professionals new to piping systems, understanding what is a flange and how different flange types and uses vary by application helps ensure safe, reliable, and serviceable connections.
In this blog post, we will discuss the seven most common types of flanges used in industrial settings.
Blind Flange
Ablind flangeis a flat plate with bolt holes that is used to close the end of a piping system. It is commonly used in applications where future expansion or maintenance may be required. Blind flanges are also used to cap off pipes or valves that are not in use. They are available in a range of sizes and materials to suit different applications.
Aweldneck flangeis a type of flange that has a long tapered hub and a neck that is welded to the pipe. The neck provides reinforcement to the pipe and allows for easy alignment during installation. Weldneck flanges are commonly used in high-pressure applications or in pipelines that carry corrosive fluids. They are available in various sizes and materials.
Aslip-on flangeis a flat plate with a bore that slips over the end of a pipe. The flange is then welded to the pipe, creating a secure and leak-proof joint. Slip-on flanges are commonly used in low-pressure applications or in pipelines that carry non-corrosive fluids. They are available in a range of sizes and materials.
Asocket weld flangeis a type of flange that is welded to the pipe using a socket weld connection. The socket weld connection provides a high-strength joint and allows for easy alignment during installation. Socket weld flanges are commonly used in high-pressure applications or in pipelines that carry corrosive fluids. They are available in various sizes and materials.
Athreaded flangeis a type of flange that has threads on the inside bore and outside diameter. The flange is screwed onto the pipe, creating a secure and leak-proof joint. Threaded flanges are commonly used in low-pressure applications or in pipelines that carry non-corrosive fluids. They are available in a range of sizes and materials.
Alap joint flangeis a type of flange that is used with a stub end. The stub end is welded to the pipe, and the lap joint flange is bolted to the stub end. Lap joint flanges are commonly used in applications where frequent disassembly is required. They are available in various sizes and materials.
Along weldneck flangeis similar to a weldneck flange, but it has a longer neck. The longer neck provides additional reinforcement to the pipe and allows for easy alignment during installation. Long weldneck flanges are commonly used in high-pressure applications or in pipelines that carry corrosive fluids. They are available in various sizes and materials.
How to Choose the Right Flange for Your Application
Selecting the right flange depends on pressure rating, operating temperature, material compatibility, and installation requirements. Knowing the different types of flanges allows engineers and procurement teams to match the flange design with system demands and long-term maintenance needs.
Conclusion
In conclusion, flanges are a critical component in industrial piping systems. Choosing the right type of flange for your application can ensure a secure and leak-proof joint, which is essential for maintaining the safety and efficiency of your operation. This overview of flange types and uses is intended to help industrial buyers make informed piping decisions.

Love your products, like your prices however I ordered components “in stock for immediate delivery”. Needed them ASAP, couldn’t upgrade delivery method. Took 8 days to print a label, didn’t get picked up by ups till day 10!
On January 28, this part was ordered. I am still awaiting a tracking details through UPS. This is for a customer who’s global valve coming off of their well leading to their irrigation supply as well as their residential water supply had broken and had a not isolated the line and cap the irrigation side off to restore water. This customer would still be without utilities. I haven’t received a tracking number out of the eight times I’ve called. I finally got through to one person and even still they couldn’t provide me with any details and this was over a week ago that I last spoke to them I have been charged. I have not received a notice that it has been shipped. I have not received the product. I would not recommend purchasing from this supplier, especially in emergency situations because of the lack of timely manner.
Ordered “in stock” items because i needed ASAP, took 8 days to print label, another two before UPS pickup, asked them to expedite shipping on day 7. No response! Not at all happy with Trypply
