An installation technique is shown for use with a pre-insulated steam piping system having an inner steel carrier pipe surrounded by a layer of foam insulation and then by an outer protective jacket. A plurality of image sources are digitally processed in the compressed domain to provide controllable enhanced user-specific interactive visualization with support for adjustment in viewing parameters such frame-rate, field of view, resolution, color format, viewpoint and bandwidth. The shift signal is determined based on an effective bit width of the input data. The ejector unit is arranged on the tool and has members which connect the ejector unit to the compressed-air pipe.
