Carbon steel end caps (pipe caps), also known as blind caps, covers, pipe covers, solid heads, are used to seal pipelines, 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 for dome caps, cone shells, reducers, flat caps, and tapered ends.

Carbon steel hem caps are mainly made of materials such as Q235, 20#, A3, 16Mn, Q345B, and 45# steel. The standards include GB/T25198-2010 (Standard for Pressure Vessel Hems) and pipeline standards GB/T12459-2005, GB/T13401-2005, etc.

Headers are an indispensable and important component in pressure vessels across various industries such as petrochemical, nuclear, and food processing.

The head is the end cover on pressure vessels and a primary pressure-bearing component.
