Abstract
A nickel alloy elbow is made of two nickel alloy plates in one-half to one-twelfth circle shapes and having same shapes by welding, the two plates are formed of plates in one-half to one-twelfth circle shapes by stamping respectively, the circular plates in the one-half to one-twelfth circle shapes form half tubes by recessing and mold pressing along circular arcs in the middles of circles, and the two half-tube arc plates are welded into the tubular nickel alloy elbow with 180 degrees to 30 degrees. The nickel alloy elbow promotes application of nickel alloy equipment, is high in cost performance, reduces equipment cost, saves precious metal materials due to being formed with large nickel alloy elbows by pressing, and increases quality of the large nickel alloy elbows.
Description
Technical field
The utility model relates to the chemical industry pipe fitting, is a kind of large-scale nickel alloy elbow in the pipe fitting goods.
Background technique
Nickel alloy material has good have superior corrosion resistance energy, mechanical property and technology capability, can be widely used at seamless conduit pipe, steam tube, and exchange of seawater device and vaporizer, sulfuric acid and hydrochloric environment, crude distillation is in fields such as seawater use equipment.The application of these materials has reduced corrosion, reduces to stop and maintenance, has improved operation stability of equipment and manufacturing efficiency, and it has good cost performance, so material is used more and more in industry.In the equipment and equipment configuration of nickel alloy application, need the large-scale equipment component of preparation.Employing pushes away curved or the large-scale nickel alloy elbow of cast form, processing difficulties, and cost is big.
The model utility content
The utility model purpose is, proposes 30 ° to 180 ° large-scale elbows of a kind of nickel alloy, improves corrosion resistance, saves cost, enhances productivity.
The technical solution of the utility model: a kind of nickel alloy elbow, it is characterized in that: be shaped by two identical shaped 1/2 to 1/12 ring nickel alloy plates and weld, these two are adopted the drawing respectively of 1/2 to 1/12 ring plate, 1/2 to 1/12 ring plate is pressed into semicanal shape along annular middle circle camber line lower cavity die, makes 180 ° of nickel alloy elbows to 30 ° of tubuloses by two semicanal shape arc plate welding.
By two identical shaped nickel alloy semi-round ring shape plates, these two semi-circular plates are pressed into semicanal shape by semi-circular line lower cavity die in the middle of annular, make 180 ° of nickel alloy elbows by two semicanal shape arc plate welding.
180 ° of large-scale elbows of nickel alloy adopt the drawing respectively of half sheet, and assembly welding becomes 180 ° of large-scale elbows again.
The same, if 90 ° of large-scale elbows of preparation nickel alloy adopt the drawing respectively of 1/4 ring plate, assembly welding becomes 90 ° of large-scale elbows again.The drawing respectively of 1/6 ring plate, assembly welding becomes 60 ° of large-scale elbows again.
The drawing respectively of 1/12 ring plate, assembly welding becomes 30 ° of large-scale elbows again.
This shows that adopt the drawing respectively of 1/2 to 1/12 ring plate, assembly welding becomes 180 ° to 30 ° elbows again.
By to elbow shaping expansion setting-out, line, jacking on plate adopt water cutter cutting arc shape work piece plate.Half sheet lay out board passes through the oil hydraulic press press forming in mould.To process, corner dimension is satisfied in assembly to the reconditioning of two halves sheet, the reconditioning bevel for welding.Behind the elbow weld seam welding forming, non-destructive inspection is qualified.Elbow welding pressure test frock, it is qualified that pressure experiment detects.
The utility model beneficial effect is: promote the application of nickel alloy equipment, high performance-price ratio reduces the equipment cost.Large-scale nickel alloy elbow press forming is saved the noble metal material.Improve large-scale nickel alloy elbow quality.Improve large-scale nickel alloy elbow and shape efficient.The utility model also can be used for other plate construction and be used to make elbow.

Embodiment
Specify mode of execution of the present utility model below:
(Fig. 1, Fig. 2, Fig. 3) can illustrate the utility model by accompanying drawing, Fig. 2 the utility model elbow expansion setting-out, extract arc plate 2, arc plate is pressed into half sheet elbow 3 in mould, and annular middle circle camber line 4 (Fig. 3), two and half sheet elbow reconditionings are to process, and corner dimension is satisfied in assembly, the reconditioning bevel for welding.180 ° of elbows 1 are made in welding; Weld seam carries out 100% radiographic inspection, and JB4730.2-2005 II level is qualified.Face of weld 100% infiltration detects, and JB4730.5-2005 I level is qualified.It is qualified that the pressure test of carrying out elbow detects.
Claims (2)
1. nickel alloy elbow, it is characterized in that: be shaped by two identical shaped 1/2 to 1/12 ring nickel alloy plates and weld, these two are adopted the drawing respectively of 1/2 to 1/12 ring plate, 1/2 to 1/12 ring plate is pressed into semicanal shape along annular middle circle camber line lower cavity die, is made 180 ° to 30 ° nickel alloy elbows of tubulose by two semicanal shape arc plate welding.
