Problems solved by technology
[0003] However, in the prior art, most of the flanges used for pipeline connection do not have a reinforced structure, resulting in poor compression resistance, which is not suitable for the connection of high-pressure pipelines, and most of the flanges used for pipeline connection have poor anti-corrosion performance, making them unable to be used for corrosive a conduit for matter, resulting in a reduction in its usefulness

Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0021] see Figure 1~5 , in the embodiment of the present invention, a new type of pressure-resistant flange for pipeline connection includes a flange plate 1, a connecting pipe 2 runs through the middle of the flange plate 1, and a reinforcing block 4 is welded on the outer surface of the connecting pipe 2, and the reinforcing block 4 respectively runs through the first reinforcement rib 5 and the second reinforcement rib 6, the flange 1 and the connecting pi...

The invention discloses a novel compression-resistant flange for pipeline connection, and relates to the technical field of flanges. The compression-resistant flange comprises a flange plate, whereina connecting pipeline penetrates through the middle of the flange plate, a reinforcing block is welded to the outer surface of the connecting pipeline, and a first reinforcing rib and a second reinforcing rib penetrates through the reinforcing block respectively. According to the compression-resistant flange, through the reinforcing block, the first reinforcing rib and the second reinforcing rib,the stability between the flange plate and the connecting pipeline is improved, that is to say, the compression resistance of the flange is increased; the corrosion resistance of the flange is improved through an anti-corrosion layer and a heat insulation layer, and the heat preservation performance of the flange is improved; through cooperative use of a second annular groove, a second adhesive and a gasket, the abrasion degree caused by the rotation of bolts and nuts on the surface of the flange plate during the connection process of the flange is reduced; and through cooperative use of a first annular groove, a first adhesive glue layer, a sealing ring and an annular groove, the sealing performance of the flange is increased.
Description
technical field [0001] The invention relates to the technical field of flanges, in particular to a novel pressure-resistant flange for pipeline connection. 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. Nowadays, the frequency of use of flanges in pipeline connections is increasing year by year. [0003] However, in the prior art, most of the flanges used for pipeline connection ...
