10” Flushing Plug

The 10” flushing cap is based on a concept that are used on hubs and flange ends when then internal ID of the hub or pipe is precisely defined with defined dimensions and tolerances.

This type of plug cannot be used for standard API pipes / pipelines where significant tolerances on ID, wall thickness and ovality have to be included. (for those applications compression packer plugs have to be employed )
