The pipe cap is a pipe fitting welded on the pipe end or installed on the external thread of the pipe end to cap the pipe, which is used to seal the pipe, with the same function as the pipe plug. The form of the pipe cap is similar to that of the blind plate, except that the blind plate can be removed for sealing, while the welded pipe cap cannot be removed.
The pipe cap includes convex pipe cap, cone shell, variable diameter section, flat cover and shrink mouth design. The difference between the pipe cap and the head is that the pipe cap is generally used in the case of low pressure, which is convenient for disassembly and maintenance. The pipe cap is generally not used in the case of medium and high pressure. The inner diameter of the head shall prevail. The diameter of the head is very large.
There is no requirement for the transition part of the pipe cap.In general, only the diameter and length can be found in the manual, and the straight side part is relatively long.Hot press forming process of carbon steel pipe cap: firstly, put the blank into the heating furnace, the heating speed above 400 ℃ is ≤ 200 ℃ / h, heat to the temperature required by the technology, and conduct heat preservation. Then put the heated blank into the adding mold, so that the blank and the mold are concentric in the circumferential direction. Start the hydraulic system to ensure the pressure is greater than 8Mpa.
