Abstract
The utility model discloses a stainless steel welded elbow, and mainly solves the problem that existing stainless steel welded elbows are poor in resistance to corrosion and high temperature. The stainless steel welded elbow comprises an elbow body (1), and is characterized in that the elbow body (1) is made of S31254 austenitic stainless steel, welding grooves (2) are arranged at two ends of the elbow body (1), and protrusions (3) protruding outwards are arranged on both ends of the elbow body (1). The stainless steel welded elbow, made of the S31254 austenitic stainless steel, is high in resistance to pitting and crevice corrosion and applicable to environments with sea water, air inflation, gaps and low-speed washing.
Description
Technical field
The utility model relates to a kind of pipe fitting, is specifically related to a kind of stainless steel weld ell.
Background technique
Elbow is the pipe fitting that changes the pipeline direction, generally adopts in pipeline is installed, and is connected in two pipes that inside nominal diameter is identical or different, makes pipeline do several angle and turns.The material of elbow has cast iron, stainless steel, alloyed steel, malleable cast iron, carbon steel, non-ferrous metal and plastics etc.The Stainless Steel Elbow of producing at present is subject to the restriction of material property in the industries such as petrochemical industry, do not possess good anti-stress corrosion and resistance to high temperature, is difficult to the environment that adapts to seawater, inflates, exists gap, low speed to wash away.
The model utility content
In order to overcome the poor and poor deficiency of resistance to high temperature of existing stainless steel weld ell corrosivity, the utility model provides a kind of stainless steel weld ell, this stainless steel weld ell adopts the S31254 Austenitic Stainless Steel, have high anti-pitting corrosion and slit and corrosion resistant performance, use under the environment of be applicable to seawater, inflating, exist gap, low speed to wash away.
The technical solution of the utility model is: a kind of stainless steel weld ell, comprise curved head body, and curved head body is the S31254 Austenitic Stainless Steel, and the two ends of curved head body are provided with bevel for welding, and the two ends of curved head body are equipped with outside projection.
Described projection is smoothly extended to the middle part from the end of curved head body.
The utlity model has following beneficial effect: owing to taking such scheme, curved head body adopts the S31254 Austenitic Stainless Steel, has high anti-pitting corrosion and slit and corrosion resistant performance, uses under the environment of be applicable to seawater, inflating, exist gap, low speed to wash away; Projection makes the wall thickness at end walls thickness rate curved head body middle part of curved head body large, can access weld strength preferably when welding, plays reinforing function.
Description of drawings
Accompanying drawing 1 is structure sectional view of the present utility model.
1-curved head body in figure, 2-bevel for welding, 3-projection.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, a kind of stainless steel weld ell comprises curved head body 1, and curved head body 1 is the S31254 Austenitic Stainless Steel, and the two ends of curved head body 1 are provided with bevel for welding 2, and the two ends of curved head body 1 are equipped with outside projection 3.Owing to taking such scheme, curved head body 1 adopts the S31254 Austenitic Stainless Steel, has high anti-pitting corrosion and slit and corrosion resistant performance, uses under the environment of be applicable to seawater, inflating, exist gap, low speed to wash away; Projection 3 makes the wall thickness at end walls thickness rate curved head body 1 middle part of curved head body 1 large, has both saved material, can access weld strength preferably again when welding, plays reinforing function.
Described protruding 3 smoothly extend to the middle part from the end of curved head body 1.This structure can effectively avoid stress to concentrate, and curved head body 1 is connected with pipeline has better join strength.
Claims (2)
1. stainless steel weld ell, comprise curved head body (1), it is characterized in that: curved head body (1) is the S31254 Austenitic Stainless Steel, and the two ends of curved head body (1) are provided with bevel for welding (2), and the two ends of curved head body (1) are equipped with outside projection (3).
2. a kind of stainless steel weld ell according to claim 1 is characterized in that: projection (3) is smoothly extended to the middle part from the end of curved head body (1).
