Abstract
The utility model discloses a hot galvanizing hubbed flange which comprises a steel pipe and a disc, wherein the steel pipe is of a hollow L shape, the steel pipe and the disc are welded together, a plurality of fixed holes are formed in the surface of the disc, a plurality of reinforcing ribs are arranged in the disc, and a hot galvanizing layer which is anticorrosive is coated on the surfaces of the steel pipe and the disc. The hot galvanizing hubbed flange has the advantages of being high in strength, large in toughness, low in cost, and long in service life.
Description
Technical field
The utility model is related to a kind of galvanizing hubbed flange.
Background technology
Flange is connected（Flange, joint）It is made up of a pair of flanges, a pad and several bolt and nuts.Pad is placed between two flange sealing surfaces, is tightened after nut, and the ratio pressure on gasket surface, which to be reached, be deformed after certain numerical value, and fills up uneven place on sealing surface, connection is not leaked tightly.Flange connection is a kind of releasable connection.It can be divided into vessel flange and tube method by the part connected；By structural shape point, there are integral (type) flange, lap joint flange and screwed flange.Common integral (type) flange has slip-on welding flange and W.N flange.The rigidity of slip-on welding flange is poor, it is adaptable to pressure p≤4MPa occasion；W.N flange is also known as hubbed flange, and rigidity is larger, it is adaptable to the higher occasion of pressure and temp.The pattern of flange sealing surface has three kinds：Plane sealing surface, it is adaptable to the occasion that pressure is not high, medium is nontoxic；Male-female seal contact face, it is adaptable to the slightly higher occasion of pressure；Tongue and groove seal contact face, it is adaptable to inflammable, explosive, poisonous medium and the higher occasion of pressure.
In high-tension apparatus and pipeline, using the metallic gasket of copper, aluminium, the lens-type that No. 10 steel, stainless steels are made or other shapes.The contact width of high-pressure spacer and sealing surface is very narrow（Linear contact lay）, the processing finish of sealing surface and pad is higher, and low pressure minor diameter has an acting flange, and high pressure and low pressure major diameter are all to use welded flange, and the thickness and connecting bolt diameter and quantity of the ring flange of different pressures are different.The height of neck is higher, and the rigidity, bearing capacity to flange increase.Compared with W.N flange, welding job amount is big, and welding rod consumption is high, is unable to undergo HTHP and alternating bending and temperature fluctuation, but in-site installation is more convenient, can omit weld seam and clap the process for rubbing wound, more welcome.
With the high speed development of automated machine equipment, the requirement more and more higher of volume and weight to plant equipment, when the weight of especially plant equipment is excessive, the freight of plant equipment will also be greatly increased, require that the ground for laying plant equipment is also reinforced accordingly, is improved the popularization expense of plant equipment, is caused plant equipment can not form the market advantage simultaneously, therefore, it is necessary to propose that a kind of new flange solves the above problems.
Utility model content
The purpose of this utility model is to provide a kind of galvanizing hubbed flange with intensity height, big toughness, low cost and long service life.
The technical solution of the utility model is：A kind of galvanizing hubbed flange, the galvanizing hubbed flange includes steel pipe and disk, the steel pipe is hollow " L " shape, the steel pipe welds together with the disk, the disc surfaces are provided with several fixing holes, several reinforcements are provided with the inside of the disk, the steel pipe and the disc surfaces scribble hot galvanized layer.
In one preferred embodiment of the utility model, the hot galvanized layer thickness is 25-30um.
In one preferred embodiment of the utility model, the number of the fixing hole is 4.
In one preferred embodiment of the utility model, the number of the reinforcement is 4.
In one preferred embodiment of the utility model, the steel pipe is hot seamless tube or stainless steel tube.
A kind of galvanizing hubbed flange of the present utility model, with intensity is high, toughness is big, low cost and the characteristics of long service life.
Brief description of the drawings
Accompanying drawing 1 is the dimensional structure diagram of the preferred embodiment of the utility model galvanizing hubbed flange one.
The mark of each part is as follows in accompanying drawing：1st, steel pipe, 2, disk, 3, fixing hole, 4 reinforcements.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the present utility model can be easier to be readily appreciated by one skilled in the art, apparent clearly defined so as to be made to protection domain of the present utility model.
Refer to Fig. 1, Fig. 1 is a kind of galvanizing hubbed flange of the utility model, the galvanizing hubbed flange includes steel pipe 1 and disk 2, the steel pipe 1 is hollow " L " shape, the steel pipe 1 welds together with the disk 2, the surface of disk 2 is provided with several fixing holes 3, the inner side of disk 2 is provided with several reinforcements 4, steel pipe 1 and the disk 2 surface scribbles hot galvanized layer, the hot galvanized layer thickness is 25-30um, the number of the fixing hole 3 is 4, and the number of the reinforcement 4 is 4, and the steel pipe is hot seamless tube or stainless steel tube.
Further illustrate, the advantage 1 of galvanizing, processing cost paper：The expense of galvanizing by dipping antirust is lower than the expense of other paint vehicle coatings；2nd, good reliability：It is metallurgical binding between zinc coat and steel, some as steel surface, therefore the persistence of coating is more reliable；3rd, the toughness of coating is strong：A kind of special metallurgical structure of Coating process, this structure can bear mechanically damaged when transporting and using；4th, comprehensive protection：The each section of plating piece can plate zinc, can be comprehensively protected even in recess, wedge angle and covert；5th, it is time saving and energy saving：Galvanizing process is more faster than the construction method of other coatings, and can avoid scheming the time needed for brush after installing on-site.Galvanizing flange has good corrosion resistance, is mainly used on the metal structure facility of every profession and trade, and he is in the zinc liquid of 500 DEG C or so thawings of immersion after flange production is molded rust cleaning, to make steel member surface attachment zinc layers, so as to play corrosion-resistant purpose.The anti-corrosion time limit of galvanizing is remote, but the anti-corrosion time limit is different in different environment：13 years, heavy industrial district, ocean 50 years, countryside 104 years, city 30 years.The utility model provides a kind of galvanizing hubbed flange, with intensity is high, toughness is big, low cost and the characteristics of long service life.
Embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the utility model; the change or replacement that can be expected without creative work, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be determined by the scope of protection defined in the claims.
