| Socket Weld Flanges | Socket for pipe insertion; welded at the hub | High-pressure systems | Pros: Strong connection; Cons: Requires precise fit and welding. |
| Threaded Flanges | Internal threads for screwing onto pipes | Low-pressure applications | Pros: No welding required; Cons: Limited to low-pressure use. |
Blind Flanges
Blind flanges are designed to seal the end of a piping system, preventing flow and allowing for future access if needed. They are commonly used in applications where a pipe may need to be inspected or modified later. For B2B buyers, selecting blind flanges means considering materials that withstand corrosion, as they often face harsh environments. However, once installed, they cannot be reused, which may not be ideal for projects with changing needs.
Slip-On Flanges
Slip-on flanges are among the most straightforward types, designed to slip over the end of a pipe and then welded in place. They are widely used across various industries due to their ease of installation and alignment. B2B buyers should note that while they are cost-effective and simpler to install, they offer less strength compared to other flange types, making them less suitable for high-pressure applications.
Weld Neck Flanges
Weld neck flanges are characterized by their long tapered neck that provides a robust weld connection to the pipe. They are often utilized in high-pressure and high-temperature applications, making them a preferred choice for critical systems in industries such as oil and gas. Buyers should consider the higher cost and complexity of installation but appreciate the durability and integrity these flanges provide in demanding environments.
Socket Weld Flanges
Socket weld flanges feature a socket that allows the pipe to be inserted before being welded at the hub. They are ideal for high-pressure systems, providing a strong connection that can handle significant stress. For B2B buyers, it is essential to ensure precise fit and alignment during installation, as any discrepancies can affect performance. While they deliver excellent strength, the requirement for skilled welding may increase project costs.
Threaded Flanges
Threaded flanges are designed with internal threads that allow them to be screwed onto the pipe, making them suitable for low-pressure applications. They are particularly advantageous in situations where welding is not feasible. Buyers should be aware that while they are easier to install and remove, threaded flanges are limited to lower pressure environments and may not be suitable for all applications.
