The utility model has the technical scheme that the glass-lined material feeding pipe comprises a pipe body which is provided with a small flange and a large flange. The glass-lined material feeding pipe is characterized in that glass-lined layers are respectively coated at the upper surface part of the small flange, the inner surface part and the outer surface part of the pipe body and the lower surface part of the large flange and are in integrated structures. The glass-lined material feeding pipe has the advantages of simple, ingenious and reasonable structure, low construction cost, long service life and safe and reliable application; the glass-lined layers are respectively coated on the inner surface and the outer surface; and the glass-lined material feeding pipe can be applied to environments with high temperature, high pressure, strong corrosion, strong oxidability, and the like.
Description
Technical field
The utility model relates to the appurtenances on a kind of chemical industry equipment, specifically a kind ofly is contained in the tank body Glassed Steel material passing tube that be used for suction, feeds intake.
Background technique
At present, in chemical industry, need to widely apply material passing tube on the chemical industry equipments such as reactor, retort.Because chemical industry equipment inside has environmental characteristicses such as high temperature, high pressure, deep-etching, strong oxidizing property, the material of material passing tube need adapt to this environment.At present, material passing tube generally adopts Stainless Steel Tube and inside and outside lining teflon steel pipe, also has a small amount of producer to adopt titanium alloy tube.Stainless Steel Tube can not contact the feed liquid with deep-etching, strong oxidizing property, and its application area is very narrow.Though inside and outside lining teflon steel pipe can contact the feed liquid of deep-etching, strong oxidizing property, but the influence of in the production process of chemical industry equipment, constantly being expanded with heat and contract with cold, teflon is easily aging under High Temperature High Pressure in addition, the crack will appear after using a period of time, cause feed liquid to infiltrate inner steel pipe, because feed liquid generally is the liquid with pH value, tube wall is easy to be corroded and ruptures and scrap, make the feed liquid variable color in the equipment simultaneously, cause quality of product to descend; And inside and outside lining teflon steel pipe generally should not carry out vacuum pumping, otherwise the teflon of material passing tube liner comes off easily, piles up the back and stops up material passing tube, not only influences output, the output value, and increased equipment cost, influence economic benefit of enterprises.Though the titanium alloy material passing tube is applied widely, it involves great expense, and working life is also not very oversize, and the maintenance cost height.
At present, the expert generally believes both at home and abroad: covering glass-lined coating at the material passing tube inner and outer surface can significantly reduce expense, improves production status, overcomes the above-mentioned adverse consequences that influences economic benefit.Outer surface all covers glass-lined coating because material passing tube requires within it, but because process characteristic, glass-lined coating generally is impossible burn till on two big planes of metal, and is particularly less for bore, the material passing tube that length is long is difficult to realize especially; Even if phenomenons such as bubble, trachoma, burst porcelain also appear in glass-lined coating easily on the plating, the defect rate height, cause product can not acid resistant alkali, high pressure resistant impact, in reactor, can't use.So just produced a technical barrier that is difficult to overcome, made many chemical industry producer still must prolong with falling behind and expensive material passing tube.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of Glassed Steel material passing tube simple in structure, ingenious, rational is provided, this material passing tube has glass-lined coating at the inner and outer surface plating, can be applicable under the environment such as high temperature, high pressure, deep-etching, strong oxidizing property, cost is low, long service life, safe and reliable.
The technological scheme that provides according to the utility model: a kind of Glassed Steel material passing tube, comprise body, body is provided with little flange and big flange, it is characterized in that: from the upper surface portion of little flange, internal surface and outer surface part to body, to the equal plating of the bottom surface section of big flange glass-lined coating is arranged again, described glass-lined coating is an integral structure.
As further improvement of the utility model, described body comprises long interior pipe and short outer tube, pipe upper end in described little flange is connected, and the interior edge of interior pipe upper end open is connected smoothly with the last plane circular arc of little flange; Described outer tube sleeve on inner pipe, the outer tube lower end is concordant with interior pipe lower end, outer tube lower ending opening edge inwardly turns down, interior pipe lower ending opening edge outwards turns down, interior pipe lower ending opening edge and outer tube lower ending opening edge circular arc seamlessly transit welding; Described big flange cover is fixed on inner pipe and with the inner tubal wall welding, and the lower plane of big flange and the outer circular arc of outer tube upper end open seamlessly transit welding.
The utility model compared with prior art, advantage is: simple in structure, ingenious, reasonable, at the inner and outer surface plating glass-lined coating is arranged, can be applicable under the environment such as high temperature, high pressure, deep-etching, strong oxidizing property, cost is low, long service life is safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Pipe, 2b-outer tube, the big flange of 3-, 4-glass-lined coating in the little flange of description of reference numerals: 1-, 2-body, the 2a-.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1, described Glassed Steel material passing tube is mainly used in the chemical industry equipments such as reactor, retort, operation such as be used for suction, feed intake.Material passing tube comprises body 2, body 2 is provided with little flange 1 and big flange 3, from the upper surface portion of little flange 1, to the internal surface and the outer surface part of body 2, to the equal plating of the bottom surface section of big flange 3 glass-lined coating 4 is arranged again, described glass-lined coating 4 is an integral structure.
As shown in Figure 1, the effect of described little flange 1 and big flange 3 is same as the prior art, promptly is used for the utility model is fixed on the use position.Because the position between little flange 1 and the big flange 3 can not touch feed liquid generally in the outside of equipment, does not therefore need plating glass-lined coating 4.In addition, the structural type of described little flange 1 and big flange 3 can be provided with flexibly according to the different of different and application site of equipment, both can be arranged to flatly, also can be arranged to oblique.
As shown in Figure 1, described body 2 is welded by long interior pipe 2a and short outer tube 2b, pipe 2a upper end in described little flange 1 is connected, and the interior edge of interior pipe 2a upper end open is connected smoothly with the last plane circular arc of little flange 1; Manage on the 2a in described outer tube 2b is enclosed within, outer tube 2b lower end is concordant with interior pipe 2a lower end, outer tube 2b lower ending opening edge inwardly turns down, and interior pipe 2a lower ending opening edge outwards turns down, and interior pipe 2a lower ending opening edge and outer tube 2b lower ending opening edge circular arc seamlessly transit welding; Pipe 2a went up and fixes with interior pipe 2a wall welding in described big flange 3 was enclosed within, and the lower plane of big flange 3 and the outer circular arc of outer tube 2b upper end open seamlessly transit welding.
