Abstract
The utility model relates to a composite bend of an aluminum oxide ceramic lining, which comprises an outer layer, a middle layer and an inner layer. The outer layer is a gapless steel pipe, the middle layer is bonding glue, and the inner layer is an aluminum oxide abrasion resistant ceramic tube. The thickness of the outer layer ranges from 6mm to 10mm, and the thickness of the inner layer ranges from 10mm to 15mm. The composite bend is high in integral strength, radically resolves the problem that the existing bend is not anti-impact, is short in service life and the like, and is good in using effect. The service life of the bend is 3 to 5 years longer than that of the existing bend. The inner surface of the bend is smooth, so that materials are not bonded to and blocked on the surface. The composite bend is convenient to use, reduces bend replacement frequency, increases material conveying quantity, improves production efficiency, saves a large quantity of overhauling time and improves cost performance of products.
Description
Technical field
The utility model relates to a kind of pipe fitting, particularly relates to a kind of aluminium oxide ceramics liner composite elbow.
Background technique
Aluminium oxide ceramics is a kind of broad-spectrum pottery, because it has superior performance, like better performances such as wear-resisting, corrosion-resistant, in industrialized production, uses more and more widely, can satisfy the needs of every profession and trade property.
Along with of the extensive use of abrasion-proof corrosion-proof parts in chemical industry and thermoelectricity industry; From the application that spreads wear-resistant bend, cast stone wear-resistant bend, wear-resistant ceramic paster elbow and bimetal wear resistant elbow more and more widely, especially wider in recent years in the application of thermal power generation industry.With the thermal power plant is example, and a large amount of pulverized fuel ash outputs is all arranged every day, grows (nearly about 1000 meters) from the firing chamber to the pipeline of ash field; The elbow that a large amount of differences are stimulated the menstrual flow being housed on the whole pipeline, facts have proved, is under the transport condition of 45 meter per seconds at the pulverized fuel ash flow velocity; The impact resistance of seamless steel pipe elbow is relatively poor; Wall thickness is that the shock point of the seamless steel pipe elbow of 10mm hole will occur and begins to leak in 40 days, and the working life of spreading wear-resistant bend certainly, the ceramic paster wear-resistant bend was not shock-resistant yet less than 6 months; Come off easily, cause steel pipe exposed.
If alumina ceramic tube and existing steel pipe are made composite pipe fitting, performances such as the high hardness of the intensity of bringing into play steel pipe simultaneously and pottery, high abrasion, corrosion-resistant, good heat resistance then can prolong working life of pipe fitting, a kind of good method of can yet be regarded as.
The model utility content
The technical problem that the utility model will solve: a kind of aluminium oxide wear-resistant ceramic composite elbow is provided, efficiently solves problems such as wear-resisting, corrosion resistance, working life of this series products is short.
The technological scheme of the utility model:
A kind of aluminium oxide ceramics liner composite elbow comprises skin, mesosphere and internal layer, and skin is a seamless steel pipe, and the mesosphere is an adhesive glue, and internal layer is the aluminium oxide wear resistance ceramic tube.
Said outer layer thickness is 6-10mm, and interior layer thickness is 10-15mm.
Said elbow also comprises flange, and said adhesive glue is an epoxy resin glue.
The positive beneficial effect of the utility model:
(1) the ceramic-lined composite elbow of the utility model; Internal layer (liner) adopts the aluminium oxide wear resistance ceramic tube, the outer seamless steel pipe that adopts, and performances such as the wear resistant corrosion resistant property of elbow, toughness, impact resistance, bending strength and thermostability improve greatly; The elbow bulk strength is higher; Fundamentally solved problems such as elbow is not shock-resistant, working life is short, elbow more common elbow in working life can improve 3-5, and using effect is better.
(2) the elbow internal surface of the utility model is smooth, and sizing putty not is not easy to use, need not to install purge hole; Serviceability temperature can reach more than 200 degree, reduces elbow and changes frequency, increases the material quantity delivered; Enhance productivity, save a large amount of repair times, improved cost performance of product.
(3) structure of the utility model is not only applicable to elbow, is applicable to other pipe fittings such as threeway, four-way, big or small first-class yet, and use face is wider.
Description of drawings:
Fig. 1: the structural representation of aluminium oxide ceramics liner composite elbow.
Among the figure, 1 is outer, and 2 is the mesosphere, and 3 is internal layer, and 4 is flange.
Embodiment:
Example 1: aluminium oxide ceramics liner composite elbow, referring to Fig. 1, comprise skin, mesosphere and internal layer, skin is a seamless steel pipe, and the mesosphere is an adhesive glue, and internal layer is the aluminium oxide wear resistance ceramic tube, and said adhesive glue is an epoxy resin glue.Outer wall thickness 10mm, internal layer wall thickness 6.5mm, the mesosphere is fit up gap 2mm.
The outer 20# seamless steel pipe that adopts, elbow stimulates the menstrual flow and is DN90mm, radius of curvature 300mm, angle 90 degree, two ends install the straight tube of 1000mm, 300mm respectively additional, connect with flange.
Example 2: aluminium oxide ceramics liner composite elbow and example 1 are basic identical, and difference is: outer seamless steel pipe wall thickness is 8mm, and the internal layer wall thickness is 12mm.
Claims (4)
1. aluminium oxide ceramics liner composite elbow, it is characterized in that: said elbow comprises skin, mesosphere and internal layer, and skin is a seamless steel pipe, and the mesosphere is an adhesive glue, and internal layer is the aluminium oxide wear resistance ceramic tube.
2. composite elbow according to claim 1 is characterized in that: said outer layer thickness is 6-10mm, and interior layer thickness is 10-15mm.
3. composite elbow according to claim 1 is characterized in that: said elbow also comprises flange.
