Pipe inflatable plug F

The Pneumatic Stopper type F is used for the temporary plugging of circular section pipes containing low pressure gas. After having correctly placed it into the pipeline by means of the handles fitted on it inflate it with air or nitrogen through a flexible hose with a valve. After use the stopper can be reused and stored in small spaces. The pneumatic stopper type F is made with gas resistant plastomers whose elasticity allows diameter expansion up to 30% of the nominal size. In this picture it is shown diameter increase during inflating.
