Steel flanges are essential components used extensively in piping systems to connect pipes, valves, pumps, and other equipment, ensuring a secure and leak-proof joint. Manufactured with precision and high-quality materials, these flanges provide durability, strength, and reliable performance in various industrial applications. Available in a wide range of sizes from 1/2” to 48”, steel flanges accommodate diverse piping requirements, making them suitable for everything from small-scale plumbing to large-scale industrial projects.
One of the prominent types within this product range is the Steel Slip On Flange, which is highly favored for its ease of installation and versatility. The Steel Slip On Flange is designed to slip over the pipe and then welded both inside and outside to provide excellent strength and leak resistance. This type of flange is especially popular in applications where welding is preferred over threading or bolting, offering a smooth bore with minimal turbulence and resistance. The Steel Slip On Flange is widely used in water, oil, and gas industries due to its reliable performance under various pressure conditions.
The steel flanges come in multiple pressure classes, including 150, 300, 600, 900, 1500, and 2500, allowing engineers and designers to select the appropriate flange for their specific pressure and temperature requirements. This extensive range of classes ensures that the flanges can handle everything from low-pressure applications to extremely high-pressure environments, maintaining the integrity and safety of the piping system. Whether it is a low-pressure water supply line or a high-pressure steam system, these flanges provide the necessary strength and resilience.
In addition to the Steel Slip On Flange, the product line includes other connection types such as welding neck, threaded, lap joint, and slip-on flanges. Each connection type offers unique benefits depending on the application. Welding neck flanges, for example, are designed for high-stress applications, providing excellent stress distribution and durability, while threaded flanges offer ease of assembly and disassembly without welding. Lap joint flanges are ideal for systems that require frequent dismantling for inspection or maintenance, thanks to their unique design that allows the flange to rotate around the stub end.
Packing and delivery are handled with utmost care to ensure that the steel flanges arrive at the customer’s site in perfect condition. The flanges are typically packed in sturdy plywood cases or on pallets to protect them from damage during transit. Custom packing solutions are also available as per the customer's specific requirements, providing flexibility and ensuring the safe and timely delivery of the products. This attention to packaging detail underscores the manufacturer’s commitment to quality and customer satisfaction.
The steel flanges are manufactured adhering to stringent quality standards and industry specifications to guarantee performance, safety, and longevity. These flanges undergo rigorous testing, including dimensional inspections, pressure tests, and material analysis, ensuring that they meet or exceed the standards required for their intended applications. This rigorous quality control process assures customers that they are receiving flanges that perform reliably under demanding conditions.
In summary, steel flanges, including the highly reliable Steel Slip On Flange, offer a versatile, durable, and efficient solution for connecting piping components across various industries. With sizes ranging from 1/2” to 48” and pressure classes from 150 to 2500, these flanges can meet diverse system requirements. The availability of multiple connection types, including welding, threaded, slip-on, and lap joint, further enhances their applicability. Coupled with customized packing options and strict quality controls, these steel flanges represent an ideal choice for engineers and procurement professionals seeking robust and dependable flange solutions for their projects.
