The pipe cap is also called a head, a plug, a cap, a pipe cover, and a bulkhead. It is welded on the pipe end or installed on the outer thread of the pipe end to cover the pipe fittings. Used to close the pipeline, the effect is the same as the pipe plug.
The form of the blind plate is similar, except that the blind plate can be removed and blocked, and the welded pipe cap cannot be removed. The tube cap includes the design of a convex tube cap, a conical shell, a reducing section, a flat cover and a tightening mouth.
Convex caps include: hemispherical caps, oval caps, dish caps, and ball crown caps. From the perspective of the force, the convex cap is gradually not good from the hemispherical cap, but from the perspective of manufacturing difficulty, it is gradually better.
