Abstract
The invention discloses a novel pressure resistance flange which comprises a pipeline, a flange plate, an anti-corrosion layer, reinforcing ribs, reinforcing bars and screw holes. The round flange plate with the screw holes is welded to the pipeline through the reinforcing ribs. The reinforcing ribs are connected to the top edge positions of the round flange plate. The reinforcing ribs are welded through fillet joints. The adjacent reinforcing ribs are connected through the strengthening bars. The stability and pressure resistance of the flange are further strengthened through the strengthening bars. The anti-corrosion layer is arranged on the end face of the flange and is made of anti-corrosion materials to prevent pipeline corrosive materials from corroding the flange, and in addition, the good sealing effect is achieved. Due to the reinforcing ribs and the reinforcing bars arranged on the flange, the stability and pressure resistance capability of the flange are greatly improved, and the flange can bear higher working pressure; and due to the anti-corrosion layer arranged on the flange, the corrosion of the pipeline corrosive materials on the flange can be prevented, and the good sealing effect can also be achieved. Thus, the overall working performance of the flange is greatly improved, and the flange is high in pressure resistance capability, simple in structure and convenient to manufacture.
Description
Technical field
The present invention relates to a kind of flange, particularly relate to a kind of butt welding pressure-proof flange.
Background technique
Flange makes pipe and the mutual flange of pipe be make pipe and the interconnective part of pipe, and in pipeline connection area, flange is played vital position by general use.The kind of flange has a variety of, butt welding welded flange has been widely used in the industry owing to having the advantages such as not yielding, good seal, the pipeline of the pipeline that be applicable to this flange pressure or temperature fluctuate widely or high temperature, high pressure and low temperature, also for carrying the pipeline 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 flange is all very of short duration, and the infringement of flange directly will 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 to pipe end meaning power all on the material and preparation process of flange, but ignore structural design to the impact of compression resistance.The design of its structure is on the impact of compression resistance.Therefore, therefore intensity, the compression resistance exigence of flange improve, and develop a kind of pressure-proof flange with anti-high pressure, can prevent the flange of material corrosion from being very important simultaneously.
The present invention is exactly the deficiency that will overcome more existing flanges, provides a kind of Novel compression-resistanflange flange.This flange both can bear higher working pressure, and material also can be prevented the corrosion of flange, had structure simple, easily manufactured feature simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of Novel compression-resistanflange flange, flange plate and the pipeline welding of this flange are integral, flange plate is provided with screw, 4 equally distributed stiffening ribs are provided with between flange plate and pipeline, between adjacent stiffening rib, be welded with stiffener simultaneously, the setting of stiffening rib and stiffener improves stability and the anti-pressure ability of flange greatly, make this flange can bear higher working pressure, flanged surface is provided with one deck anticorrosive coat, this anticorrosive coat can prevent corrosion of piping material to the corrosion of flange, also can realize compared with sealing effect, thus greatly improve the service behaviour of flange entirety.
In order to solve the problem, the present invention is achieved through technology,
Novel compression-resistanflange flange, comprises pipeline, flange plate, anticorrosive coat, stiffening rib, stiffener, screw.Flange plate is the disk having screw, is realized together with pipeline welding by equally distributed stiffening rib; Stiffening rib is used for connecting tube and flange plate, and play the effect of fastening flange and pipeline, 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 the stability and crushing resistance that strengthen flange are further set; Anticorrosive coat is arranged on the end face of flange, is made up of corrosion-resistant material, is used for preventing corrosion of piping material to the corrosion of flange, also can realize compared with sealing effect.Flange plate and the pipeline welding of flange are integral, flange plate is provided with screw, 4 equally distributed stiffening ribs are provided with between flange plate and pipeline, between adjacent stiffening rib, be welded with stiffener simultaneously, the setting of stiffening rib and stiffener improves stability and the anti-pressure ability of flange greatly, make this flange can bear higher working pressure, flanged surface is provided with one deck anticorrosive coat, this anticorrosive coat can prevent corrosion of piping material to the corrosion of flange, also can realize compared with sealing effect, thus greatly improve the service behaviour of flange entirety.
This Novel compression-resistanflange flange has stiffening rib, and stiffening rib is connected between flange plate and pipeline by the mode of welding.
This Novel compression-resistanflange flange has stiffener, and stiffener is connected between adjacent stiffening rib by the mode of welding.
This Novel compression-resistanflange flange has anticorrosive coat, and anticorrosive coat is made up of anti-corrosion-resistant material.
Have employed technique scheme, the invention has the beneficial effects as follows:
A kind of Novel compression-resistanflange flange, this flange plate and pipeline welding integral, flange plate is provided with screw, 4 equally distributed stiffening ribs are provided with between flange plate and pipeline, between adjacent stiffening rib, be welded with stiffener simultaneously, the setting of stiffening rib and stiffener improves stability and the anti-pressure ability of flange greatly, make this flange can bear higher working pressure, flanged surface is provided with one deck anticorrosive coat, this anticorrosive coat can prevent corrosion of piping material to the corrosion of flange, also can realize compared with sealing effect, thus greatly improve the service behaviour of flange entirety, anti-pressure ability is strong, structure is simple, easily manufactured.
Therefore, the present invention, compared with common flange plate, has outstanding advantage and is: (1) can bear higher working pressure; (2) prevent material to the corrosion of flange; (3) structure stability is good, and structure is simple, easily manufactured.
