Product Name
Stainless Steel Forged WN Flange
Product Description
Stainless steel welding neck flanges, as high-quality pipeline connection components, play a crucial role in numerous industrial fields.
In terms of material, it selects high-quality stainless steel, such as the commonly seen 304 and 316 grades. 304 stainless steel has good corrosion resistance and can adapt to general acid-base environments, being widely used in ordinary industrial scenarios like the food and chemical industries. 316 stainless steel, with its higher molybdenum content, has even stronger corrosion resistance and is suitable for fields with demanding corrosion resistance requirements, such as marine engineering and pharmaceuticals, ensuring long-term stable operation under complex working conditions.
In appearance, it features a protruding neck. This design makes the pipeline connection more stable. The neck is welded to the pipeline, increasing the connection strength and enabling it to effectively bear the stress caused by the pressure and temperature changes of the medium inside the pipeline. Its butt-welding end is precisely machined to ensure the fit when welding with the pipeline, guarantee the welding quality, reduce welding defects, and thus ensure the sealing performance of the entire pipeline system.
It comes in a variety of size specifications, covering compact flanges suitable for smaller pipe diameters to large-diameter flanges required for large industrial pipelines, meeting the needs of different project scales and different flow transmission requirements. Small-sized flanges are often used in fine chemical and laboratory pipeline systems. They are easy to install and have low space requirements. Large-sized flanges undertake the connection tasks of major projects such as oil and natural gas transmission trunk lines, ensuring the safe and efficient transmission of massive amounts of medium.
Regarding surface treatment, polishing treatment can be carried out to make the flange surface as smooth as a mirror. It is not only aesthetically pleasing but also easy to clean, meeting the standards of industries with strict hygiene requirements such as food, beverage, and pharmaceuticals. Passivation treatment can also be carried out according to requirements to further enhance its corrosion resistance and extend its service life.
During installation, it closely cooperates with matching gaskets and bolts. The gasket selects appropriate rubber, graphite or metal materials depending on the sealing requirements of different working conditions. The bolts ensure that the tightening force is evenly applied, making the flange and the pipeline connect into a reliable whole, safeguarding the smooth operation of various industrial processes.
To sum up, stainless steel welding neck flanges, with their excellent materials, exquisite designs, diversified specifications and reliable performances, have become an indispensable high-quality choice for modern industrial pipeline connections.
