Abstract
The utility model discloses a bimetallic composite elbow. The elbow comprises an arc-shaped pipe body (1), wherein pipe interfaces (2) are arranged at the two ends of the pipe body (1). The arc-shaped pipe body (1) includes an inner anticorrosion layer (3) and an outer carbon steel layer (4) which are compounded through metallurgy, so as to achieve the excellent anticorrosion performance of anticorrosion alloy steel or stainless steel, the high-intensity property of carbon steel, as well as low cost; and particularly, due to the groove design which is used for the welding between the elbow and a pipeline, the elbow can be firmly combined with the pipeline, avoid leakage, and ensure that the original excellent anticorrosion performance is not influenced by welding.
Description
Technical field:
The utility model relates to a kind of elbow, the bimetal composite elbow that especially a kind of antiseptic property is good, with low cost.
Background technique:
Elbow is to list that " pipe joint and pipe fitting are selected the standard pipe joint of handbook for use, have been widely used in the pipeline of industries such as oil, chemical industry, water power, metallurgy, weaving in.The structure of existing elbow is that the arc body is arranged, there is interface tube at the two ends of arc body, its arc body is to be made by homogenous materials such as high-intensity carbon steel or corrosion resistant alloyed steel or Ovshinsky stainless steels, the carbon steel cost is low but antiseptic property is poor, though and corrosion resistant alloyed steel or Ovshinsky stainless steel antiseptic property are good, cost is higher.
Summary of the invention:
The utility model is in order to solve the above-mentioned technical problem of existing in prior technology, to provide a kind of antiseptic property good, with low cost bimetal composite elbow.
Technical solution of the present utility model is: a kind of bimetal composite elbow, the arc body is arranged, and there is interface tube at arc body two ends, and described body is composited by anticorrosion internal layer and the outer metallurgy of carbon steel.
The anticorrosion internal layer and the carbon steel skin of described interface tube port are stepped, described anticorrosion internal layer lordosis 2～6mm.
The outer field end face of described carbon steel is served as reasons interior to outer inclined downward.
Tilt angle, the outer field inclined-plane of described carbon steel is 20～25 degree.
The outer field inclined-plane of described carbon steel is divided into two sections from the inside to the outside, and first section tilt angle is 22.5～32.5 degree, and second section tilt angle is 9～11 degree.
Arc body of the present utility model is to be composited by the outer metallurgy of anticorrosion internal layer and carbon steel, and existing corrosion-resisting alloy steel or stainless excellent corrosion resistance have the high-strength characteristic of carbon steel again, and be simultaneously with low cost.Design especially for groove, can guarantee with the pipeline strong bonded, can not produce seepage, can guarantee that again original excellent corrosion resistance does not change because of welding with the pipeline welding.
Description of drawings:
Fig. 1 is the utility model embodiment 1,2 a structural representation.
Fig. 2 is the utility model embodiment 1 a divided edge structure schematic representation.
Fig. 3 is the utility model embodiment 2 a divided edge structure schematic representation.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.The utility model embodiment 1,2 basic structure as shown in Figure 1, shape arc body 1 same as the prior art is arranged, there is interface tube 2 at the two ends of body 1, different is that described arc body 1 is composited by outer 4 metallurgy of anticorrosion internal layer 3 (as nickel-base alloy, titan-based alloy or stainless steel) and carbon steel with prior art, methods such as available existing blast, soldering, hydraulic buckling, make the compound body or the composite sheet of metallurgy combination, further process again.Groove design is that layering is welded in the time of should guaranteeing weld with pipe fitting, can be as Fig. 2, shown in Figure 3: the anticorrosion internal layer 3 of interface tube 2 ports be stepped with carbon steel outer 4, described anticorrosion internal layer 3 lordosis 2～6mm, the end face of carbon steel skin 4 serve as reasons interior to outer inclined downward.Embodiment 1 groove is as shown in Figure 2: the tilt angle, inclined-plane of described carbon steel skin 4 (promptly and the angle of interface tube 2 between radially) is 20～25 degree.Embodiment 2 groove is as shown in Figure 3: the inclined-plane of described carbon steel skin 4 is divided into two sections from the inside to the outside, and the tilt angle of first section (19mm is thick) is 22.5～32.5 degree, and second section tilt angle is 9～11 degree.
Specification of the present utility model and pattern size and tolerance should meet the regulation of GB/T12459 or GB/T13401.
