High neck flange carbon steel stainless steel butt welded flange pipe connection, pressure resistant seal

Description :

High neck flange, also known as butt welding flange or neck welded flange, is a key connecting component widely used in industrial pipeline systems. This product is professionally produced by Hebei Yichuan Pipeline Equipment Manufacturing Co., Ltd. It is forged from high-quality carbon steel, stainless steel, or alloy steel materials and has the characteristics of high strength, high pressure resistance, high temperature resistance, and excellent sealing performance.

The design feature of the high neck flange lies in its neck structure, which has the same wall thickness as the pipeline. It is connected to the pipeline through butt welds, thereby achieving a smooth transition in strength between the flange and the pipeline. This structural design not only effectively reduces stress concentration and improves connection reliability, but is also particularly suitable for high-temperature, high-pressure, and temperature changing working environments, such as petroleum, chemical, power, shipbuilding, and building water supply and drainage.

During the product manufacturing process, strict adherence to national standards (GB), mechanical industry standards (JB), chemical industry standards (HG), and international standards (ANSI/ASME, DIN, JIS, etc.) is ensured to ensure that the dimensional accuracy and mechanical properties of each product meet industry requirements. There are various forms of flange sealing surfaces, including protruding surface (RF), concave convex surface (MFM), tenon groove surface (TG), etc., which can be customized according to specific customer needs to adapt to different gasket types and sealing requirements.

Hebei Yichuan Pipeline Equipment Manufacturing Co., Ltd. has advanced production equipment and testing methods. From raw material storage to finished product delivery, every process undergoes strict quality control. The surface of the product has undergone sandblasting and anti-corrosion treatment, resulting in a smooth and clean appearance with clear markings. The company is committed to providing customers with high-quality pipeline accessory solutions, and its products are exported to domestic and foreign markets, deeply trusted by users. Whether it is a new project or an old pipe renovation, choosing the high neck flange of Yichuan Pipeline can provide safe, stable, and long-term operation guarantee for your pipeline system.
