Abstract
The invention relates to a novel compression-resistance flange which comprises a pipeline, a flange plate, an anticorrosive layer, reinforcing ribs, stiffeners and a screw hole, wherein the circular flange plate with the screw hole is welded on the pipeline together through the reinforcing ribs; the reinforcing ribs are connected to the top edge of the circular flange plate in an angle joint welding mode; the stiffeners are used for connecting adjacent reinforcing ribs, and the stability and compression resistance of the flange are further strengthened through arrangement of the stiffeners; the anticorrosive layer is arranged on the end face of the flange, is made of a corrosion resistant material, is used for preventing corrosion material of the pipeline from corroding the flange, and can also achieve a good sealing effect. Due to arrangement of the reinforcing ribs and the stiffeners, the stability and compression resistance of the flange are greatly improved, so that the flange can bear higher working pressure. Due to arrangement of the anticorrosive layer, the corrosion material of the pipeline cannot corrode the flange, a good sealing effect is achieved, and therefore the integral working performance of the flange is greatly increased. The flange has the advantages of high compression ability, simple structure and convenience in manufacturing.
Description
Technical field
The present invention relates to a kind of flange, relate in particular to a kind of butt welding resistance to compression flange.
Background technique
Flange is that to make pipe and the mutual flange of pipe be to make pipe and the interconnective part of pipe, and in the pipeline connection area, flange is by general use and play vital position.The kind of flange has a variety of, the advantages such as the butt welding welded flange is not yielding owing to having, good seal have been widely used in industry, the pipeline that be applicable to this flange pressure or temperature fluctuate widely or the pipeline of high temperature, high pressure and low temperature, also on the pipeline for delivery of expensive, inflammable, explosive medium.In present many chemical pipelines, all there is the operating mode of high pressure, under the impact of strong pressure, the life-span of a lot of flanges is all very of short duration, and the infringement of flange will directly have influence on whole work system, in some corrosion-prone operating modes, end face of flange can lose efficacy because of the erosion of corrosion materials.At present, for the research of flange compression resistance, be connected in pipe end meaning power all on the material and preparation process of flange, but ignore the impact of structural design on compression resistance.The design of its structure on the impact of compression resistance.Therefore, therefore the intensity of flange, compression resistance exigence improve, and develop a kind of resistance to compression flange with anti-high pressure, can prevent that the flange of material corrosion from being very important simultaneously.
The present invention is exactly the deficiency that will overcome more existing flanges, and a kind of novel resistance to compression flange is provided.This flange both can bear higher working pressure, also can prevent the corrosion of material to flange, had characteristics simple in structure, easily manufactured simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of novel resistance to compression flange is provided, flange plate and the pipeline welding of this flange are integral, flange plate is provided with screw, be provided with 4 equally distributed stiffening ribs between flange plate and pipeline, be welded with stiffener simultaneously between adjacent stiffening rib, the setting of stiffening rib and stiffener has improved stability and the anti-pressure ability of flange greatly, make this flange can bear higher working pressure, be provided with one deck anticorrosive coat on flanged surface, this anticorrosive coat can prevent the corrosion of corrosion of piping material to flange, also can realize sealing effect, thereby greatly improve the service behaviour of flange integral body.
In order to address the above problem, the present invention is achieved through technology,
Novel resistance to compression flange, comprise pipeline, flange plate, anticorrosive coat, stiffening rib, stiffener, screw.Flange plate is the disk that has screw, by equally distributed stiffening rib, realizes together with pipeline welding; Stiffening rib is used for connecting tube and flange plate, plays the effect of fastening flange and pipeline, and each stiffening rib is connected to the top margin position of circular flange dish, and stiffening rib adopts the welding manner of fillet joint; Stiffener is used for connecting adjacent stiffening rib, stiffener further stability and crushing resistance of having reinforced flange be set; Anticorrosive coat is arranged on the end face of flange, corrosion-resistant material, consists of, and is used for preventing the corrosion of corrosion of piping material to flange, also can realize sealing effect.Flange plate and the pipeline welding of flange are integral, flange plate is provided with screw, be provided with 4 equally distributed stiffening ribs between flange plate and pipeline, be welded with stiffener simultaneously between adjacent stiffening rib, the setting of stiffening rib and stiffener has improved stability and the anti-pressure ability of flange greatly, make this flange can bear higher working pressure, be provided with one deck anticorrosive coat on flanged surface, this anticorrosive coat can prevent the corrosion of corrosion of piping material to flange, also can realize sealing effect, thereby greatly improve the service behaviour of flange integral body.
This novel resistance to compression flange has stiffening rib, and stiffening rib is connected between flange plate and pipeline by the mode of welding.
This novel resistance to compression flange has stiffener, and stiffener is connected between adjacent stiffening rib by the mode of welding.
This novel resistance to compression flange has anticorrosive coat, and anticorrosive coat is comprised of anti-corrosion-resistant material.
Adopted technique scheme, the invention has the beneficial effects as follows:
A kind of novel resistance to compression flange, this flange plate and pipeline welding are integral, flange plate is provided with screw, be provided with 4 equally distributed stiffening ribs between flange plate and pipeline, be welded with stiffener simultaneously between adjacent stiffening rib, the setting of stiffening rib and stiffener has improved stability and the anti-pressure ability of flange greatly, make this flange can bear higher working pressure, be provided with one deck anticorrosive coat on flanged surface, this anticorrosive coat can prevent the corrosion of corrosion of piping material to flange, also can realize sealing effect, thereby greatly improve the service behaviour of flange integral body, anti-pressure ability is strong, simple in structure, easily manufactured.
Therefore, the present invention compares with common flange plate, and have outstanding advantage and be: (1) can bear higher working pressure; (2) prevent the corrosion of material to flange; (3) structure stability is good, simple in structure, easily manufactured.
