The appearance and use of the tube cap and people's understanding
I'm sure many of you shudder when you first hear the term "tube cap." What the hell is a pipe cap? What does it look like? What is it for? But this cap is all too common to a mechanic. In fact, ah, tube cap is also called plug, cover, tube cover, head, these names are good to let a person understand. It is a pipe fitting welded to the pipe end or mounted on the outer thread of the pipe end to cover and block the pipe. Used to seal the pipeline, the function is the same as pipe blocking.
The blind plate is similar in form, except that the blind plate is removable plug, while the welded pipe cap is not removable. The pipe cap includes convex pipe cap, cone shell, reducer section, flat cover and the design of tightening mouth.
Convex pipe cap includes: hemispherical pipe cap, oval pipe cap, disc pipe cap and dome pipe cap. From the point of view of force, convex pipe cap is gradually bad from the hemispherical pipe cap, but from the point of view of manufacturing difficulty, gradually good manufacturing. And the pipe cap from the use of material can be divided into copper pipe cap, iron pipe cap, stainless steel pipe cap, plastic pipe cap and other common pipe cap!
At present, there are many kinds of pipe caps on the market, because the application of the industry is also very many, at present in petrochemical, nuclear power, machinery, fertilizer, shipbuilding, water treatment, pipes, water heating, solar water heater and many other industries need to be applied to the pipe cap!
There are about 17 kinds of pipe caps according to the pressure grade, which are the same according to the standard pressure grade of the customer, including Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s and XS. Sch80, SCH100, Sch120, Sch140, Sch160, XXS STD and XS are commonly used. The pipe cap is not very common in industrial buildings. The necessary pipe cap is only used at the pipe end of the pipe for sealing the pipe, which is basically the same as the blind plate, that is, the blind plate can be removed when installed, but the pipe cap can not be removed. The pipe cap is welded on the pipe, which is very close to the form of the blind plate.
The above is the general use of the cap, in fact, a little attention can be seen that the cap is also divided into many types, so it can not be generalized, and the cap and head in the literal sense of the same, in fact, the distinction is not small: The head is used for the upper and lower parts of the container equipment (vertical equipment) or the left and right ends (horizontal equipment) of the pipe cap is generally the outer diameter size, the pipe cap can be directly screwed on the pipe, no other pipe fittings are required. &a
