304/304L/316/316L Stainless Steel Pipe Fitting Cap
Tube cap, also known as head, plug, cover head, pipe cover, bulkhead, is welded on the pipe end or installed on the external thread of the pipe end to cover the pipe fittings. Used to close the pipeline, the function is the same as the pipe plug.
It is similar in form to the blind plate, except that the blind plate is a detachable block, and the welded pipe cap cannot be removed. The cap includes the design of convex cap, conical shell, reducing section, flat cover and shrinking mouth.
Convex caps include: hemispherical caps, elliptical caps, disc caps and spherical caps. From the point of view of force, the hemispherical cap is gradually not good in the convex cap, but it is gradually easier to manufacture in terms of manufacturing difficulty.
Avoid splicing at the r of the dish cap, which will reduce thinning and high stress.
When splicing, the welding seam direction requirements are only allowed to be radial and circumferential. Large caps may remove this requirement in the future. The distance of splicing should be required, which is greater than 3δ and not less than 100mm (welding heat-affected zone is a high-stress zone, and the chemical composition in this zone will be burnt. Therefore, it is necessary to avoid the high-stress zone, which is related to the thickness. .According to practical experience, the stress decay length is greater than 3δ and not less than 100mm). However, it is difficult for refrigeration equipment to meet this requirement and has its particularity.
After splicing, the spliced head and spliced weld should be 100% ray or ultrasonic tested, and the qualification level will follow the equipment shell. The inspection level and ratio of the final formed weld seam are the same as the equipment shell, which is highly wasteful. Example: If the equipment shell is 20% tested, III is qualified. The bulkhead splicing weld and the final weld are also III qualified, and the welding joint coefficient is 0.85;
If the equipment housing is 100% tested, II is qualified. The bulkhead splicing weld and the final weld are also II qualified, and the welding joint coefficient is 1
Therefore, although the bulkhead splicing is 100% tested, the qualification level is different, and it follows the equipment shell.
But pay attention to the craft manufacturing process:
The correct way is: blanking (scribing) - small plates are assembled into large plates - forming - non-destructive testing
If it is wrong to test before molding, the quality of the product after molding cannot be guaranteed. That is to say, non-destructive testing refers to the final non-destructive testing.
