Product Description
The Welding Neck Flange is a critical component widely used in piping systems to ensure secure and leak-proof connections. This flange type features a long tapered hub that provides excellent stress distribution and resistance to dishing and distortion under high pressure and temperature conditions. It is ideal for applications requiring high strength and reliability, making it a preferred choice in industrial sectors such as oil and gas, petrochemical, and power generation.
Manufactured in China, this Welding Neck Flange is made from high-quality materials including ER 309L Mo and ER 316L Si (F316). These materials are selected for their superior corrosion resistance, durability, and mechanical properties, ensuring the flange performs exceptionally well in harsh environments. ER 309L Mo offers excellent resistance to oxidation and high-temperature corrosion, while ER 316L Si (F316) provides enhanced resistance to pitting and crevice corrosion in chloride environments. This combination guarantees a long service life and reliability under demanding conditions.
The flange is designed as a Slip On Flange, meaning it can be slipped over the pipe and then welded in place. This design simplifies installation and alignment, reducing labor time and costs while maintaining a strong and secure joint. Slip On Flanges are versatile and widely used in various piping systems, providing an effective solution for connecting pipes, valves, pumps, and other equipment.
Compliance with international standards is a key feature of this Welding Neck Flange. It meets the stringent requirements of ASME B16.5, ASME B16.47, and API 6A standards. ASME B16.5 covers pipe flanges and flanged fittings for sizes from NPS 1/2 through NPS 24, ensuring the flange dimensions and pressure-temperature ratings meet industry expectations. ASME B16.47 extends these specifications to larger sizes beyond NPS 24, while API 6A sets the standard for wellhead and Christmas tree equipment flanges, ensuring reliability in critical oil and gas applications. This adherence to standards guarantees compatibility, safety, and performance across a wide range of applications.
The material number assigned to this Welding Neck Flange is P245GH, a commonly used grade in pressure vessel and piping applications. P245GH is known for its excellent mechanical properties, including high tensile strength and good weldability, making it suitable for use in high-temperature and high-pressure environments. This material ensures the flange can withstand demanding operational conditions without compromising integrity or safety.
In addition to its robust construction and material quality, this Welding Neck Flange is designed to meet European standards such as EN 1092-1. It is available as an EN 1092-1 Weld Neck Flange 1.4541 (321) Stainless PN16 with a Raised Face. The raised face design enhances the sealing surface, improving gasket performance and sealing reliability. The 1.4541 (321) stainless steel grade offers excellent resistance to sensitization and intergranular corrosion, making it suitable for high-temperature applications. Furthermore, the P355GH flange EN 1092-1 standard ensures the flange conforms to European norms for pressure and temperature ratings, materials, and dimensions, providing assurance of quality and compatibility within European piping systems.
This product is ideal for engineers and procurement specialists seeking a reliable and high-performance Welding Neck Flange that meets both American and European standards. Its combination of premium materials, precise manufacturing, and compliance with ASME, API, and EN standards makes it suitable for a wide range of industrial applications. Whether used in new installations or maintenance projects, this Welding Neck Flange promises durability, safety, and efficient performance.
To summarize, the Welding Neck Flange with China material ER 309L Mo + ER 316L Si (F316), designed as a Slip On Flange and conforming to ASME B16.5, ASME B16.47, API 6A, and EN 1092-1 standards, represents a superior choice for demanding piping systems. Its material number P245GH and features such as the EN 1092-1 Weld Neck Flange 1.4541 (321) Stainless PN16 | Raised Face and P355GH flange EN 1092-1 ensure it meets the highest quality and performance benchmarks. This flange is an essential component for ensuring the integrity and safety of industrial piping networks worldwide.
