Internal Alignment Clamps 4S is an immediate fast, safe and exact centring and tensioning of flanges, brackets, rings, etc. on pipes and cylindrical tanks. Comes with a contact surface for smooth flanges. Automatic diameter compensation even for extremely varied diameters via independently tensible bracing elements. Our centring device is fixed with the lower expansion element in the pipe, the flange or similar attached and finally centred and clamped using the upper expansion element.
In order to prevent electric corrosion, we recommend the versions with stainless steel support rails (VA 1.4301).
