Hi athomas236
this is quite common practice here in europe. Companies like Siemens and Alstom are using this type of inserter. On a piston they connect a metal bar. Also they are using a ball valve or a gate valve. When they like to insert the target into de steam line they open the valve and with the pisten they are moving the target into the steam line. This system only works with continous steam blowing.
