Features with welding neck flange：
1.Definition: Welding neck flangeis a type of flange with a tapered neck and butt weld to the
the barrel or pipe.
2.Features: Due to the transition structure of the cone 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. The disadvantage is that it needs to be manufactured with
forgings, which consumes a lot of materials and has a large manufacturing cost. Suitable for
applications where pressure, temperature is high or where sealing is required.
3.Integral flange:The integral flange is a flange connection. It is also a type of welding neck f
lange. It is mostly used in pipes with higher pressures.
