Oval plugs offer the possibility of sealing pipes of different sizes with an oval profile. In this type of pipes, a safe sealing with round plugs IS NOT POSSIBLE since in the small lower radius (sole) a hundred percent tightness cannot be achieved.
The obturators of oval profile are characterized by their rubber coating, free of seams and expandable, made of robust rubber material. Due to its construction we avoid a longitudinal extension of the shutters.
Oval profile plugs are manufactured in five sizes and fit all existing oval pipes. Other sizes can be manufactured on request.
Large filling diameter facilitates fast filling and emptying
Completely flexible
Easy introduction into the well
Very ductile material, good adaptation to the oval profile
Patented, seamless, stretchable rubber coating
Security:
Tear-resistant aramid fabric cover and floor
Abrasion resistant
With an operating overpressure of 1.0 bar (14.5 psi) a back pressure of 0.5 bar (7.25 psi) is achieved
The 1.5 bar (21.75 psi) oval profile plugs are characterized by their compact construction and offer a significant advantage over the 1.0 bar (14.5 psi), which can seal two pipe diameters with a single obturator with an oval profile due to the great expansion of the cushion cover material.
The smooth surface is a guarantee for permanent quality during pipe remediation. This plug is also manufactured as a check and bypass plug with internal hose. On customer request, other sizes and lengths can also be supplied here.
Advantage:
Folding cushion
Great ductility
Long life
Also available in other materials, for example CR
Handy and light
Security:
Possible back pressure of 0.5 bar (7.25 psi)
Safety valve incorporated in the control device to prevent inadvertent overfilling.
