Ductile iron flange products

Ductile iron flange product connection is two pipes, pipe fittings or equipment, first fixed on a flange, between the two flange, plus flange pad, with bolts together, complete the connection. Some pipe fittings and equipment have their own flange, which also belongs to flange connection. Flange connection is an important way of pipeline construction. The flange connection is easy to use and can bear large pressure. In the industrial pipeline, in the family, the pipeline diameter is small, and it is low pressure, no flange connection can be seen. If in a boiler room or production site, there are flange connected pipes and equipment everywhere.
According to the connection mode, flange connection types can be divided into: plate flat welding flange, neck flat welding flange, neck butt welding flange, socket welding flange, threaded flange, flange cover, neck butt welding ring loose sleeve flange, flat welding ring loose sleeve flange, ring groove face flange and flange cover, large diameter flat flange, large diameter high neck flange, 8-shaped blind plate, butt welding ring loose sleeve flange, etc.
As the iron plate welding flange, many customers question whether the quality of iron plate welding flange is better than forging welding flange. In fact, the quality of the iron plate welding flange is the same as that of the forged welding flange, but where can the iron plate welding flange not be protected? That is, the material of the iron plate welding flange is the least protected, because in the general process, there is no problem with the density of the iron plate welding flange, but in the process of production, The blank of iron plate welding flange is rarely detected, so after the production, the material of iron plate welding flange without detection cannot be protected.
