The cap refers to the element used to close the end of the container and isolate the internal and external media. According to the shape of the head surface, it can be divided into convex shape, conical shape, flat shape and combined shape.
Carbon steel pipe cap is a pipe fitting welded on the pipe end or installed on the external thread of the pipe end to cover and block the pipe. According to the design, the pipe cap can be divided into convex pipe cap, conical shell, variable diameter section, flat cover and tight mouth. The convex pipe cap also includes hemispherical pipe cap, oval pipe cap, dished pipe cap and spherical crown pipe cap
The cap and cap are very similar in shape, and their main differences lie in the inner diameter and scope of use. The pipe cap is only the plug of the pipeline, which usually does not exceed DN300. If the DN exceeds 300, it should be replaced by the head. The can be infinite, and the equipment limit is generally about dn6000.
The cap is applied to various vessel equipment, such as storage tank, heat exchanger, tower, reactor, boiler and separation equipment.
The pipe cap is used to close the pipeline, which has the same function as the pipe plug, and is generally used under low pressure, which is convenient for disassembly and maintenance. The pipe cap is generally not used under high and medium pressure.
