Carbon Steel Caps

Carbon Steel Caps, also known as plugs, caps, pipe caps, or plugs, are used to seal pipelines. They have the same function as pipe plugs, but the pipe caps can be directly screwed onto the pipes without the need for other fittings. The design of the pipe cap includes a convex pipe cap, a conical shell, a variable diameter section, a flat cover, and a tightening mouth.

The main materials include Q235, 20 #, A3, 16 manganese, Q345B, 45 steel, etc. The standards include GB/T25198-2010 (Pressure Vessel Head Standard), as well as pipeline standards GB/T12459-2005, GB/T13401-2005, etc.
