Abstract

The invention relates to the technical field of flange plates, and discloses an anti-bending-moment flange plate for a petroleum pipeline. The anti-bending-moment flange plate comprises a first flange plate and a second flange plate, the first flange plate and the second flange plate are connected together in an abutting manner, the two opposite sides of the first flange plate and the second flange plate are integrally connected with welding necks, and multiple connecting screw holes which are annularly distributed are uniformly formed in the surfaces of the first flange plate and the second flange plate. Multiple reinforcing rib plates which are annularly distributed are welded to the opposite sides of the first flange plate and the second flange plate. The anti-bending-moment flange plate for the petroleum pipeline has the advantages that the lateral stress strength of the first flange plate and the second flange plate is guaranteed through multiple arranged lateral reinforcing plates, the problem that due to the fact that the bending moment of the connecting position, corresponding to the first flange plate and the second flange plate, of the pipeline is too large, bending and breaking are likely to occur, and use of the pipeline is affected is avoided, and the connecting strength of the first flange plate and the second flange plate is greatly improved.

Description

technical field

[0001] The invention relates to the technical field of flanges, in particular to a moment-resistant flange for oil pipelines. Background technique

[0002] Flange is otherwise known as flange flange or flange. Flanges are parts that are connected to each other between shafts and are used for connection between pipe ends; they are also useful for flanges on equipment inlets and outlets, And can be used as connection between two equipments, example reducer flanges. Flange connection or flange joint refers back to the detachable connection of flange, Gasket and bolt as a team of combined sealing structure. Pipe flange refers back to the flange used for piping in the pipeline installation, And used on the equipment refers to the inlet and outlet flange of the equipment. There are holes in the flange, and the bolts tightly connect the two flanges. The flanges are sealed with gaskets. Flanges are divided into threaded (screw connection) flanges, welding flanges...
