The plate flange is the most common flange. Because the plate flange has good comprehensive performance, it is widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electric power, shipbuilding and other basic projects.

Our welding materials products consist of three major series: solid welding wires, flux-cored welding wires, and welding electrodes, with over 200 varieties in total. In addition to their conventional applications, our products are also evolving towards specialized welding materials for high-strength steel, heat-resistant steel, stainless steel, and non-ferrous metals. These welding materials are widely used in various industries, including steel structure construction, shipbuilding, pressure vessels, oil pipelines, rail transit, marine engineering, and nuclear power.

Welding neck flange refers to a flange with a tapered neck and butt-welded to the cylinder or pipe. It is an integral flange. Due to the transition structure of the tapered neck and the butt welding connection, the strength and rigidity of the flange are enhanced, and the sealing is better than plate flange.

Slip-on flange is the full name of necked flat welding steel pipe flange. It is a flange that connects steel pipes, pipe fittings, etc. to equipment or pipelines through fillet welds. Slip-on flange is also a plate flange with a neck. The short neck improves the strength of the flange and improves the bearing capacity of the flange. Therefore, it can be used on pipelines with higher pressure.

A socket welding flange is a flange that is welded on the pipe end and the outside by inserting the pipe end into the flange ring step. The socket welding flange has good rigidity, small welding deformation and good sealing. It is commonly used in boiler pressure vessels, petroleum, chemical industry, shipbuilding, pharmaceuticals, metallurgy, machinery, stamping elbows, food and other industries.
