When planning a project that involves piping or industrial systems, selecting the correct type of flange can ensure the integrity and efficiency of the entire system. Flanges come in various designs, each suited for specific applications. Knowing the differences between flange types can help you choose the best one for your project’s needs. Working with an experienced flanges supplier in Dubai can also provide valuable insights into making the right selection.
Weld neck flanges:
Weld neck flanges are commonly used in high-pressure applications, offering strong, reliable connections. These flanges have a long neck that allows them to be welded to the pipe, which provides a smooth transition from the flange to the pipe. This type of flange is ideal for systems that experience extreme pressure and temperature conditions, such as in the oil and gas industry.
Slip-on flanges:
Slip-on flanges are designed to slide over the pipe and be welded in place. They are cost-effective and easy to install, making them suitable for applications that don’t require the high strength of a weld neck flange. Slip-on flanges are typically used in low-pressure systems, where there is no significant risk of leakage, but a secure connection is still necessary.
Blind flanges:
Blind flanges are used to close the end of a piping system, effectively sealing it off. These flanges do not have a central hole and are primarily used in maintenance or when a temporary closure is required. They are often found in applications where future inspection or modifications may be needed. Blind flanges can handle high pressure and are usually used in high-strength systems.
Threaded flanges:
Threaded flanges feature internal threads that allow them to be screwed directly onto pipes with matching external threads. This type of flange is ideal when welding isn’t an option or when the pipe material can’t be welded. Threaded flanges are commonly used in systems where disassembly and reassembly are needed frequently, as they can be easily removed and replaced without welding equipment.
Socket weld flanges:
Socket weld flanges are used for small-diameter piping systems and are welded into place by inserting the pipe into the flange socket. They provide a strong, leak-proof connection and are typically used in high-pressure systems with small pipes. Socket weld flanges are commonly used in the aerospace, chemical, and pharmaceutical industries due to their reliability and durability.
