M-Pipe & Fitting Solution Inc is a reputable company that manufactures and supplies high-quality long weld neck flanges. Long Weld Neck Flanges (LWN flanges) are a type of pipe flange that provides a robust and reliable connection between pipes, valves, and other equipment. They are widely used in various industries, including oil and gas, petrochemical, and power generation.
Long Weld Neck Flanges: Long Weld Neck Flanges, also known as LWN flanges, are designed with an extended neck or hub that provides additional strength and reinforcement to the flange. They are typically used in high-pressure and high-temperature applications. The extended neck allows for easy alignment of the bolt holes and provides a smooth transition for the flow of fluids.
Raised Face Long Weld Neck Flanges: Raised Face Long Weld Neck Flanges are specifically engineered to create a raised surface (a small raised portion around the bore) that acts as a sealing area. The raised face provides a secure and reliable connection when compressed against a gasket, minimizing the risk of leaks. These flanges are commonly used in applications that involve moderate to high pressures and temperatures.
Flat-Face Long-Weld Neck Flanges: Flat-Face Long-Weld Neck Flanges feature a flat face without protrusions or raised surfaces. They are primarily used in applications that require connecting non-metallic or low-pressure piping systems. These flanges provide a smooth and even sealing surface for gaskets, ensuring a tight seal to prevent leakage.
Ring Type Joint Long Weld Neck Flanges: Ring Type Joint (RTJ) Long Weld Neck Flanges are designed with a unique groove that accommodates a metal ring gasket. The RTJ gasket provides excellent sealing performance, making these flanges suitable for high-pressure and high-temperature applications. The groove’s precise machining and the appropriate gasket material ensure a reliable and leak-free connection.
Compact Flanges Long Weld Neck: Compact Flanges Long Weld Neck, also known as Hubbed Compact Flanges, combines the features of a welded neck flange and a compact flange. They offer significant space and weight savings compared to traditional flange connections. These flanges are widely used in offshore oil and gas installations, where reducing weight and increasing structural integrity is crucial.
Long Weld Neck Flanges are vital in various industrial applications, providing a robust and leak-free connection between pipes and equipment. Understanding the different types of LWN flanges, including Raised Face Long Weld Neck Flanges, Flat Face Long Weld Neck Flanges, Ring Type Joint Long Weld Neck Flanges, and Compact Flanges Long Weld Neck, professionals can select the most suitable option for their specific requirements. Whether it’s high-pressure and high-temperature applications or space and weight-saving considerations, there is a long weld neck flange variant designed to meet the diverse needs of modern industries. M-Pipe & Fitting Solution Inc provides certified flanges that meet international standards such as API, ASTM, and ISO 9001:2015.
