NXF ASTM A240 316H /1Cr17Ni12Mo2/31609 DN15-1200 Class 150-2500 Forging Hexagonal Head Plug

The main part of the hexagonal head threaded pipe plug includes a hexagonal head and a threaded part. The hexagonal head makes installation and removal easy with a wrench or other tools, while the threaded portion ensures the plug will stay tightly on the pipe. This design makes the pipe plug easy to operate and effective in sealing. It is a part used to prevent liquid leakage. It is usually fixed on the pipe through a threaded connection to prevent liquid or gas from leaking from the pipe. Therefore, it is often literally translated as "pipe blocking" in the fastener industry.
