ASME B16 5 Long Weld Neck Flange Manufacturer

We are ASME B16.5 Long Weld Neck Flange Manufacturer, Supplier, and Exporter in India — Shribhairav Forge is a trusted manufacturer and exporter of ASME B16.5 Long Weld Neck Flanges, offering high-quality products built for durability, precision, and performance. Our Long Weld Neck (LWN) Flanges are designed for critical applications where high pressure, high temperature, and cyclic loading conditions exist.

What are Long Weld Neck Flange?

Long Weld Neck (LWN) flanges are a unique variety of flange characterized by an extended neck that gradually narrows to align with the wall thickness of a pipe or vessel. This extended neck offers additional support and facilitates a seamless transition of stress between the flange and the attached pipe, rendering them suitable for high-pressure, high-temperature, or critical service applications. They are predominantly utilized in process plants, refineries, and power generation systems.

The key characteristic of a Long Weld Neck flange is its extended hub or neck, which functions as an integrated nozzle. In contrast to standard weld neck flanges, the LWN flange can be welded directly to a vessel or pipe without requiring an additional pipe extension. This design enhances structural integrity, decreases turbulence, and lowers the likelihood of leakage. They are generally offered in a range of pressure ratings and materials, including carbon steel, stainless steel, and alloy steel, based on the specific application needs.

Long Weld Neck flanges are primarily used in pressure vessels, heat exchangers, and storage tanks where high stress and frequent temperature variations occur. Their robust construction ensures excellent resistance to bending, vibration, and corrosion. By maintaining proper alignment and providing a strong, leak-proof connection, LWN flanges enhance the safety and efficiency of piping systems in demanding industrial environments.
