Product Advantages

Our flange factory always adheres to the concept of superior quality. The flanges we produce strictly comply with advanced domestic and international standards. We implement strict quality control starting from the selection of raw materials. We use high - quality steel to ensure that the flanges possess excellent strength and corrosion resistance. With advanced forging and processing techniques, each flange is endowed with precise dimensional tolerances and a smooth surface finish. Whether in high - pressure, high - temperature working conditions or highly corrosive environments, they can operate stably and reliably, serving as a secure connection cornerstone for various pipeline systems. 

About flange

Flange Types (by Connection Method)

Integral Flange
Integrally manufactured with the inlets/outlets of pumps, valves, machinery, and other equipment as part of the equipment itself, it features a firm connection and is suitable for applications requiring high tightness and strength.
Slip-On Flange (SO Flange)
Also known as lap-joint flange, it connects by inserting the pipe end into the bottom or inner opening of the flange socket, with the pipe end positioned below the inner plane of the flange. Welding is performed on the outer edge or both the inner and outer edges of the flange. 
Weld-Neck Flange (WN Flange)
Also called high-neck flange, it has a long, inclined neck extending from the welding joint with the pipe to the flange disc. The wall thickness transitions gradually along the height to the pipe wall thickness, improving stress discontinuity and enhancing strength. 
Loose Flange (Lap Joint Flange)
Commonly known as a loose flange, it is divided into welded ring loose flanges, flanged loose flanges, and butt-welded loose flanges. The flange can rotate for easy alignment of bolt holes, making it convenient for installing large-diameter pipelines.
Threaded Flange
The inner hole is machined with pipe threads to connect with pipes featuring external threads, making it a non-welded flange. It has a nominal diameter range of DN8–DN100 and a working pressure of 1.0–2.5 MPa.
