Steel flanges are essential components widely used in piping systems to connect pipes, valves, pumps, and other equipment, ensuring a secure and leak-proof assembly. Originating from China, our steel flanges are manufactured with precision and adhere to stringent international standards, making them a reliable choice for various industrial applications. These flanges are available in multiple pressure classes, including 150, 300, 600, 900, 1500, and 2500, catering to a wide range of pressure and temperature requirements.
Our product range covers various types of steel flanges, including the popular Steel Plate Flange, Steel Socket Weld Flange, and Steel Flange Ring. The Steel Plate Flange is known for its flat face and solid construction, making it ideal for high-pressure applications and providing a robust connection point in piping systems. The Steel Socket Weld Flange offers a smooth bore with a socket for the pipe to fit into, enabling a strong welded joint that is both leak-resistant and durable. The Steel Flange Ring is frequently used in bolt-on connections and serves as a versatile component in many flange assemblies.
Manufactured in compliance with internationally recognized standards such as ANSI, JIS, DIN, BS, UNI, EN, GOST, and others, our steel flanges meet the quality and dimensional requirements demanded by global industries. This compliance ensures compatibility and interchangeability with existing piping systems, facilitating easy installation and maintenance. Whether your project requires flanges conforming to American, European, or Asian standards, our products provide the flexibility and assurance needed for seamless integration.
The steel flanges are designed with various connection types to suit different piping configurations and installation needs. Welding flanges provide a permanent and robust joint through butt welding, commonly used in high-pressure and high-temperature environments. Threaded flanges offer a convenient, no-weld option for low-pressure applications, where pipes can be screwed in directly. Slip-on flanges allow pipes to slide into the flange before welding, simplifying alignment and installation. Lap joint flanges, used in conjunction with stub-end fittings, facilitate quick disassembly and are preferred in systems requiring frequent inspection and maintenance.
Packaging is a critical aspect of our steel flange delivery process. To ensure that the flanges reach customers safely and without damage, they are packed in sturdy plywood cases or on pallets. Additionally, we are flexible and accommodate custom packing requirements based on the specific needs of our clients. This attention to packaging detail guarantees that every Steel Plate Flange, Steel Socket Weld Flange, and Steel Flange Ring arrives in optimal condition, ready for immediate use.
Originating from China, our steel flanges combine superior material quality with advanced manufacturing techniques. This blend results in highly durable and corrosion-resistant products capable of withstanding harsh industrial environments. The availability of multiple pressure classes, adherence to various international standards, and diverse connection types make our steel flanges suitable for industries such as oil and gas, petrochemical, power generation, water treatment, and construction.
In summary, our steel flanges offer a comprehensive solution for piping connections, emphasizing quality, versatility, and reliability. Whether you need a Steel Plate Flange for a high-pressure pipeline, a Steel Socket Weld Flange for a secure welded joint, or a Steel Flange Ring for a bolted connection, our products meet rigorous standards and customer specifications. With flexible packaging options and multiple classes and standards available, our steel flanges from China stand out as a trusted choice for engineers, contractors, and procurement professionals worldwide.
