  • Our company is pleased to offer a wide range of high-quality flanges, including WN flanges, SO flanges, and SW flanges. Each of these flanges has its own unique characteristics that make them suitable for various applications. Our WN flanges, also known as weld neck flanges, are ideal for high-pressure applications. They are designed with a tapered hub that can be easily welded to the pipe, providing a strong and leak-free connection. The long neck of the WN flange also helps to reduce stress concentrations, making it an excellent choice for pipelines that experience thermal expansion and contraction. Our SO flanges, or slip-on flanges, are the most commonly used flange type. They are easy to install and are suitable for low-pressure applications. The SO flange has a flat face that allows it to be easily aligned with the pipe, and it is held in place with two fillet welds. Finally, our SW flanges, or socket weld flanges, are used in situations where high pressure and temperature ratings are required. These flanges have a socket-like bore that is welded to the pipe, providing a strong and leak-free connection. SW flanges are commonly used in high-pressure pipelines and are frequently used in the petrochemical and power generation industries. At our company, we are committed to providing our customers with the highest quality flanges at competitive prices.
