The exploded view of the retrieval tool shown below in Figure 3 illustrates some of the exclusive safety and convenience features available only from Metal Samples.
The retrieval tool is constructed to comply with NACE MR0175 for a working pressure of 6000 psi. The standard tool is suitable for operation between -15°F and 400°F (-26°C and 204°C). A low temperature version is available upon request for operation between -30°F and 250°F (-34°C and 121°C). Optional seal materials for higher and lower temperature ratings are available. Please contact your Metal Samples sales representative for options.
The retrieval tool is normally supplied as a kit complete with field service case, assembly accessories and one O-ring seal kit. Tool size, or stroke, is determined by the combined maximum pipeline size and the maximum height of any access fitting assembly with which the tool will be used. The stroke is defined as the distance that the plug/sensor assembly must travel to permit the service valve to close.
Metal Samples retrieval tool part numbers for various pipeline sizes are given below. If the required pipeline size falls between two size ranges, the larger tool should be selected.
