B16.11 A182 F316L Forged Threaded Hex.and Round Head Plug
Threaded hexagonal plugs, also known as threaded pipe caps, threaded caps, threaded pipe caps, threaded stuffy heads, are installed on the external threads of the pipe ends to cover the pipe fittings. It can be used to close the pipeline. It has the same function as pipe plugging. It can be directly screwed on the pipe without any other pipe fittings. The plug includes the design of convex plug, conical shell, variable diameter section, flat cover and contraction opening.
