ASTM A234 Gr.WPB ASME B16.9 14 Inch Steel Pipe Cap , Steel Tube End Caps SCH 20

ASTM A234 Gr.WPB Alloy Steel Cap, ASME B16.9, Wrought, 14 Inch, SCH 20, SMLS, Coating.

Steel pipe cap refers to pipe fittings welded to the end of the pipe or threaded to cover the pipe. According to the material can be divided into carbon steel pipe cap, alloy steel pipe cap, stainless steel pipe cap.
The steel pipe cap is used to close the pipe and acts the same as the pipe plug. The form of blind plate is close, but the blind plate is detachable and the welded pipe cap is not detachable. The cap comprises a convex cap, a conical shell, a variable diameter section, a flat cover and a design of.

Type
The form of blind plate is close, but the blind plate is detachable and the welded pipe cap is not detachable. The cap comprises a convex cap, a conical shell, a variable diameter section, a flat cover and a tight port.
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.

There are about 17 kinds of pipe caps classified according to pressure grade, which is the same as that of American pipe pressure grade, Sch5s,Sch10s,Sch10,Sch20,Sch30,Sch40s,STD,Sch40,Sch60,Sch80,XS;Sch80,Sch100,Sch120,Sch140,Sch160,XXS; the most commonly used are STD and XS. The pipe cap is not very common in industrial buildings. The pipe cap is only used at the end of the pipe to close the pipe. It is basically the same as the blind plate, that is, the blind plate can be disassembled, and the pipe cap is welded to the pipe and is very close to the blind plate.

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. 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 refers to the final nondestructive testing.

The cap is also called plug, cap, pipe cover, stuffy head, these names are easy to understand. It is welded to the end of the pipe or installed on the outer thread of the end of the pipe to cover the pipe. Used to close the pipe, the function is the same as the pipe plug. Close to the form of blind plate, but blind plate is detachable plugging, and welded pipe cap is not detachable. The cap comprises a convex cap, a conical shell, a variable diameter section, a flat cover and a design of a contraction port.
Convex cap includes: hemispherical cap, elliptical cap, butterfly cap and spherical cap. From the point of view of force, the hemispherical tube cap in the convex tube cap is gradually bad, but from the point of view of manufacturing difficulty, it is gradually easy to manufacture. The pipe cap can be divided into copper pipe cap, iron pipe cap, stainless steel pipe cap, plastic pipe cap and so on.
