Product Name
Stainless Steel Forged WN Flange
Product Description
Experience the paramount quality of our stainless steel welding neck flanges, meticulously crafted to serve as integral pipeline connection components across diverse industrial sectors.
Crafted from superior stainless steel, including the renowned 304 and 316 grades, these flanges showcase exceptional corrosion resistance. The 304 grade stands out for its adaptability in typical acid-base environments, making it a preferred choice for industries like food and chemicals. Meanwhile, 316 stainless steel, bolstered by increased molybdenum content, excels in environments demanding superior corrosion resistance, such as marine and pharmaceutical applications, ensuring steadfast performance under challenging conditions.
With a distinctive protruding neck, these flanges ensure a more robust and stable pipeline connection. The neck welds seamlessly to the pipeline, enhancing the connection's strength and resilience against the dynamic stresses of pressure and temperature fluctuations within the pipeline. Its expertly machined butt-welding end guarantees a flawless fit, minimizing welding defects and securing the entire pipeline system's sealing performance.
Available in a comprehensive range of size specifications, our flanges cater to both compact setups for smaller diameters and large-diameter applications for extensive industrial pipelines. Compact flanges are ideal for precise chemical and laboratory systems due to their ease of installation and minimal space requirements. Conversely, large flanges are indispensable for substantial projects like oil and gas transmission, ensuring the safe and efficient handling of vast media volumes.
Our surface treatments, including mirror-like polishing, provide a visually appealing and hygienic finish, crucial for industries with strict cleanliness standards such as food, beverage, and pharmaceuticals. Optional passivation treatment further augments corrosion resistance, thereby extending the flange's service life.
Each installation pairs these flanges with compatible gaskets and bolts, utilizing materials like rubber, graphite, or metal to meet diverse sealing requirements. The bolts distribute pressure evenly, creating a dependable, unified connection between the flange and pipeline, ensuring seamless industrial operations.
In conclusion, our stainless steel welding neck flanges, with their superior materials, refined designs, broad specifications, and dependable performance, stand as a vital, high-quality solution for contemporary industrial pipeline connections.
