Galvanized Iron Pipe Thread Flange

Galvanized flanges, a type of malleable iron pipe fitting, are pipe connections made of malleable cast iron that have undergone hot-dip galvanizing. Their core is made of malleable iron with excellent toughness, and a dense alloy coating is formed on the surface through a high-temperature galvanizing process. This gives them superior rust and corrosion resistance, making them particularly suitable for humid or outdoor environments. As a critical interface in piping systems, galvanized flanges are mainly used for pipe sections that require frequent disassembly, equipment valve connections, or the connection of different piping systems. They are fastened to another flange with bolts and a gasket is installed in between to achieve a high-strength connection and reliable sealing of the pipeline. They are commonly used in low-pressure fluid transportation systems such as water, gas, and oil.

1.High quality materials Cast iron workmanship

Cast iron is mainly composed of iron, carbon and silicon alloy of the general term, with high strength, good toughness, plasticity and cutting and machining properties

2.Flat bottom and reliable load-bearing

In our production process, we give priority to using high-quality professional machines to ensure the precision and efficiency of our products. Additionally, each piece is fully rust-resistant to enhance its durability and corrosion resistance. In addition, each product is thoroughly stress tested before leaving the factory to guarantee its functionality and reliability under various operating conditions.

3.wide range of uses Variety of possibilities with fittings

Our fittings kindly used to water,gas,fire fighting system ...and now more and more customer use the fittings DIY the lamp,bookshelf...which looks more nice than usual.

4.Threaded flanges are flanges that are connected to pipes using threads. It can be regarded as a loose flange, and its advantage is that no welding is required. In addition, when the flange deforms, the additional moment acting on the cylinder or pipe is minimal. This makes it an easy and efficient choice for joining pipes, ensuring a safe and secure connection without the need for welding operations. The threaded design facilitates installation and maintenance, providing flexibility and versatility for a variety of industrial applications.

5.Threaded flange is a kind of non-welding flange that the inner hole of the flange is processed into pipe thread and matched with the pipe with thread to achieve connection. It is compared with flat welding flange or butt welding flange, threaded flange has the characteristics of easy installation and maintenance, and can be used in some pipelines where welding is not allowed on site. Alloy steel flange has enough strength, but not easy to weld, or welding performance is not good, can also choose threaded flange.
