Description

Pipeline connection forging flange plate

Technical Field

The embodiment of the disclosure relates to the technical field related to flange plates, in particular to a flange plate for connecting a pipeline with a forging piece.

Background

In modern industrial production, flanges are widely used in various fields as a key connecting part. The flange, also called flange collar or flange, is mainly used for connection between shafts, pipe ends and between equipment inlets and outlets, so as to ensure stable transmission of medium in various systems. Among the various connection modes, flange connection is an important choice for connection of industrial pipelines and equipment by virtue of the advantages of detachability, tightness and the like, wherein bolts and studs are common elements for realizing flange connection, and flanges are tightly connected by pretightening force generated by tightening the bolts or nuts.

However, the conventional flange connection method has a plurality of disadvantages. Firstly, the traditional flange is directly connected and fixed by bolts, and under the actual working condition, the pipeline or equipment can be subjected to various complex external forces, such as pressure fluctuation of internal media, vibration impact of external environment, stress generated by thermal expansion and cold contraction and the like. When these external forces cause the flanges to bend, deformation is very likely to occur between the two flanges. The deformation not only can damage the structural integrity of the flange, reduce the structural strength of the flange, but also can seriously affect the tightness of the whole device. In systems that deliver flammable, explosive, toxic and hazardous media, loss of tightness can cause serious safety accidents, threaten personnel life safety, cause environmental pollution and huge economic loss.

Secondly, due to the deficiencies of the conventional flange in terms of structural strength and tightness, the service life thereof is also relatively short. Frequent maintenance and flange replacement not only increase the production cost of enterprises, but also can lead to the extension of equipment downtime, influence production efficiency and restrict the economic benefits of enterprises.
