Steel Pipe Cap A403 INOX 304L Stainless Steel Cap ,8 lnch ,SCH 10S, Forged ,for Pipe Connection

A pipe cap is a pipe fitting welded to the end of the pipe or threaded to cover the pipe. Used to close the pipe, the function is the same as the pipe plug. The pipe cap is also called a plug, a cap, a pipe cover, and a stuffy head. Used to close the pipe, the function is the same as the pipe plug, but the pipe cap can be directly rotated on the pipe, no other pipe fittings. It is generally used at the end sampling port of the pipe. After the sampling is completed, the pipe cap should be screwed on. The other is that under special circumstances, after the pipe cap is removed, the pipe can be connected with the wire mouth, and the material can be taken or pumped continuously. Pipe cap in the case of low pressure, easy to disassemble and repair, high pressure generally do not use the cap. The cap comprises a convex cap, a conical shell, a variable diameter section, a flat cover and a tight port. The pipe cap is similar to the head shape, the material is more stainless steel, the pipe cap size is smaller, can be forged; the head size is larger, generally pressed with steel plate, the pipe cap is generally used at the end of the pipe, Head for upper and lower container equipment (vertical equipment) or left and right end (horizontal equipment). Convex tube cap includes: hemispherical tube cap, elliptical tube cap, disc tube cap and ball crown tube cap. From the point of view of force, the hemispherical tube cap is not good, but from the point of view of manufacturing difficulty, it is easy to manufacture.

Avoid splicing at the r of the disc cap and reduce thinness and high stress.
The weld direction requirement is only radial and circumferential. The large cap may cancel this requirement in the future. The distance of splicing should be more than 3δ, and not less than 100 mm. So avoid the high stress zone, which is related to thickness. The stress attenuation length is greater than 3δ, and not less than 100 mm according to practical experience). But the refrigeration equipment is very difficult to meet this requirement, has its particularity.
After splicing the head, splicing weld should be 100% ray or ultrasonic inspection, qualified grade with the equipment shell. The final weld inspection grade and proportion are the same as the equipment shell, which is high waste.
hemispherical head
Example: if the equipment shell is 20% test, III qualified. And the weld seam and final weld seam are III qualified, welding joint coefficient of 0.85;
If the equipment shell is 100% test, II qualified. And the weld seam and the final weld seam are II qualified, and the coefficient of welded joint is 1
So stuffy splicing although 100% detection, but the level of eligibility is different, with the equipment shell.
But pay attention to the process manufacturing process:
The correct approach is: blanking (marking)- small plates assembled into large plates - molding - nondestructive testing
If it is wrong to test before molding, the quality of the product after molding can not be guaranteed. That is to say, nondestructive testing is the

final nondestructive testing
