Plugging and test technology

Fluvius offers a wide range of inflatable plug, flow and test stoppers from Sava for numerous nominal widths as well as the corresponding accessories.   more...

These inflatable pipe stoppers are suitable for use in various types of pipelines. The selection of products ranges from individually dimensioned inflatable elements for sealing pipelines of uniform diameter to multi-dimensional inflatable stoppers for the sealing of pipelines of various diameters. Inflatable stoppers (Plugy) can be inserted in wastewater pipelines to close the flow, or as rear pipe inflatable stoppers for an air tightness test. Inflatable flow stoppers (Plugsy) have a threaded aluminium pipe vulcanised into the rubber section, thus allowing wastewater flow.

These inflatable pipe stoppers can be used as inflatable front pipe stoppers during the air tightness test. Depending on the work to be carried out, these may be used for inspection, cleaning, maintenance and during repair work. The top quality products offered by Fluvius are characterised by their durability and therefore high degree of economy. Individual customer wishes can be taken into consideration during production.

Single- and multi-dimensional inflatable stoppers with large diameters for the plugging, diversion and pressure testing (air, water) for pipe diameters from DN40 to DN1500. All inflatable stoppers are equipped for inflating with a fast coupling.  more...

As the inflatable pipe stoppers are particularly flexible, they can be inserted through drains sized 600 x 600 mm and bent to an angle of 90°. Due to their high degree of elasticity, they can cover various diameters if used correctly.

These multi-dimensional inflatable pipe stoppers are suitable for the sealing or testing of water and gas pipes with limited entrance opening. The combination of a measuring and plugging stopper enables leak tightness tests of water and gas pipelines with air or water.  more...

Due to their high degree of elasticity, six different types can cover the range from DN50 to DN500 if used properly. All metals are made of rust-free and non-sparking materials. The innovative shape and flexibility allow easy application and ensure quality work from a single position.

The inflatable pipe stoppers are resistant to high dynamic pressure and are characterised by their quality and durability. Two types of gas pipe stoppers are available: Measuring and plugging stoppers.

These multi-dimensional pillow-shaped pipe stoppers can be used for the plugging, diversion and pressure testing (air, water) and are lightweight and particularly flexible due to their simple construction and the use of top-quality materials.  more...

Hence, the largest inflatable pipe stopper with a diameter of 2000 mm can be inserted through a standard 60 x 60 cm drain without any problems. The inflatable pipe stoppers are characterised by easy handling, not only in round pipes, but also in egg-shaped and elliptical pipes. Thanks to the special rubber compound, good sealing is ensured in contact with the most varied materials such as e.g. concrete, plastic and iron.
