Abstract
The utility model discloses a bimetallic composite reducing joint. The reducing joint comprises a straight reducing pipe body (1), wherein pipe interfaces (2) are arranged at the two ends of the pipe body (1). The straight reducing 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, in the groove design for the welding between the reducing joint and a pipeline, the reducing joint is firmly combined with the pipeline, leakage is avoided, and the original excellent anticorrosion performance can not be changed due to the welding.
Description
Technical field:
The utility model relates to a kind of reducer fitting, the compound reducer fitting of bimetal that especially a kind of antiseptic property is good, with low cost.
Background technique:
Reducer fitting 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 reducer fitting is that straight shape reducing body is arranged, there is interface tube at the two ends of straight shape reducing body, its straight shape reducing 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 good, the with low cost bimetal of a kind of antiseptic property compound reducer fitting.
Technical solution of the present utility model is: the compound reducer fitting of a kind of bimetal, straight shape reducing body is arranged, and there is interface tube at straight shape reducing 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.
Straight shape reducing 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.

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 straight shape reducing 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 straight shape reducing 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.
