Below picture shows that 380mm plug is tested in 400mm,500mm and 550mm pipeline.
One plug can be used in different size pipe,is it possible?
Rubber pipe plugs is made of high quality rubber material with multi-scope design concept, so good physical property is one of its basic characteristic, its elongation is over 300%. Good tensile property can make plugs expand to different size in designed range and keep needed pressure, so it is possible that one plugs can be used in different size pipeline, it is also called multi size type plugs. This type plugs is our independent research and development, it came into the market in 2016. The current model is DN98, DN180, DN250,DN380, DN580 and DN780, As to the details, please you can reference below table.
