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

Carbon steel head materials mainly include Q235, 20#, A3, 16Mn, Q345B, and 45 steel, etc. Standards include GB/T25198-2010 (Pressure Vessel Head Standard), 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, including petrochemicals, nuclear energy, and food processing.

The head is the end cover of a pressure vessel and a major pressure-bearing component of the pressure vessel.
