Plate flat welding flange
Plate flat welded flanges are relatively common flanges. Because plate flat welded flanges have good comprehensive performance, they are widely used in chemicals, construction, water supply, drainage, petroleum, light and heavy industries, refrigeration, sanitation, plumbing, fire protection, Basic projects such as electric power and shipbuilding.
Flat welding flange with neck
Neck flat welded flanges are called flat welded steel pipe flanges with necks. They are flanges that extend steel pipes, pipe fittings, etc. into the flange and connect them to equipment or pipelines through fillet welds. Flat-welded flanges with necks are also flat-welded flanges, because they have a short neck, which increases the strength of the flange and improves the load-bearing strength of the flange. So it can be used in higher pressure pipelines.
Butt welding flange with neck
Neck butt welding flange refers to a flange with a tapered neck and butt welding with the cylinder or pipeline. 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 strengthened, and the sealing performance is better than that of the flat welding flange.
Socket welding flange
Socket welding flange refers to the flange where the end of the pipe is inserted into the flange ring ladder and welded on the end and outside of the pipe. Socket welded pipe flanges have good rigidity, small welding deformation and good sealing performance. Commonly used in boiler pressure vessel, petroleum, chemical, shipbuilding, pharmaceutical, metallurgy, machinery, stamping elbow food and other industries
