Technical Field
The invention relates to the technical field of end sockets, in particular to a novel cross-border type end socket and a forming method thereof.
Background
The end cap is an element for sealing the end of the container to isolate the internal and external media, and is also called an end cap. The closure head of a cylindrical container is generally a swivel housing. The shape of the seal head surface can be divided into convex, conical, flat and combined shapes. The convex end socket refers to an end socket with a convex outer surface shape, such as a hemispherical, oval, dished and edgeless spherical end socket. Some gas cylinders adopt a combined bottom seal head with an inward convex surface, so that the strength can be ensured, and the requirement for safe use can be met.
The seal head is an end cover on the pressure vessel and is a main pressure-bearing part of the pressure vessel. The function is to seal. Firstly, the upper bottom and the lower bottom of the pot-shaped pressure container are made, secondly, the pipeline is finished and is not ready to extend forwards, and then a seal head is used for sealing the pipe in a welding mode. Products that function much like closures have blind flanges and caps, but those two products are removable. And the seal head can not be detached after being welded. The matched pipe fittings comprise products such as a pressure container, a pipeline, a flange plate, an elbow, a tee joint, a cross joint and the like, and the quality of the seal head is directly related to the long-term safe and reliable operation of the pressure container.
However, in a high-pressure working environment, the conventional end socket can only bear the high-pressure working environment by means of the compressive strength of the end socket and the welding strength between the traditional end socket and a pressure container, the sealing state is adversely affected in a long-term compressed state, and once leakage occurs, personal safety and property loss are easily caused.
