Tube cap is also known as head, plug, cover, etc., it is welded in the pipe end or installed on the pipe end of the external thread to cover the pipe fittings, used to close the pipeline.

Tube cap is also known as head, plug, cover, etc., it is welded in the pipe end or installed on the pipe end of the external thread to cover the pipe fittings, used to close the pipeline. The head and the cap are very similar in appearance, and some say that the head is like a pan. The difference between the cap and the head is mainly in the size of the inner diameter and the scope of application. The head and the official cap look very similar, but the official cap and the head are very different, the difference between the two mainly lies in the size of the inside diameter and the scope of use. It has also been said that the pipe cap is only the plug of the pipeline. If DN exceeds 300, it should be replaced by the head. If pressure is applied, the strength should be checked. The head is an inside diameter of 1 meter, which refers to the inside diameter of the tube cap. There is no requirement for the transition part.

Head and the shape of the official cap although almost, the use of stainless steel head is very much, in our words here the difference between the head and the official cap is that the head does not have a neck, the official cap has a neck, but the size of the tube cap is relatively small, so it can be forged; The size of the head is relatively large, and it is generally pressed with steel plate. The pipe cap is generally used for the end of the pipe, and the head is used for the upper and lower parts of the container equipment or the left and right ends.

Generally speaking: the cap and the head shape is similar, the material is stainless steel more, the cap size is relatively small, can be forged; The head size is a little larger, generally pressed with steel plate, tube cap is generally used for the end of the pipe, the head is used for the upper and lower parts of the container equipment (vertical equipment) or the left and right end (horizontal equipment). Convex pipe caps include: hemispherical pipe caps, oval pipe caps, dished pipe caps and spherical cap. From the point of view of force, the hemispherical tube cap in convex tube cap is gradually bad, but from the point of manufacturing difficulty, it is gradually better to manufacture.

Generally speaking, the head is the inner diameter, such as 1 meter, refers to the inner diameter tube cap on the transition part did not make requirements (unlike the standard oval), the general manual can only find the diameter and length, and the straight side part is longer. The pipe cap is only the plug of the pipe. If DN exceeds 300, it should be replaced by the head. If pressure is applied, the strength should be checked. Tube cap applied in water, beverage, beer, food, petrochemical industry, nuclear power, machinery, medical equipment, chemical fertilizer, shipbuilding, waterproof treatment, pipeline and other packaging: wooden boxes, carton services: provide technical advice, guide installation and other dish-shaped tube cap r to avoid splicing, thin, high stress.
