Carbon steel end caps (pipe caps), also known as plug heads, cover heads, pipe caps, blind heads, are used to seal piping, serving the same function as pipe plugs but can be directly screwed onto pipes without the need for additional piping components. End caps include designs such as dome caps, cone shells, reducers, flat caps, and constrictions.

Carbon steel hem materials mainly include Q235, 20#, A3, 16Mn, Q345B, 45 steel, etc. Standards include GB/T25198-2010 (Standard for Pressure Vessel Hem) and pipeline standards GB/T12459-2005, GB/T13401-2005, etc.

The head is an indispensable and essential component in pressure vessel equipment across various industries such as petrochemicals, nuclear energy, and food processing.

A head is the end cover on pressure vessels and a main component that bears pressure.
