摘要： A header delivery system and method for performing a pigging operation on a process tube connected to a header pipe. The header delivery system is insertable in the header pipe and has a launcher pipe for launching an inspection or cleaning tool to the process tube. A tube coupler for coupling to the process tube and a bumper are connected to the launcher pipe. A jack apparatus is configured to position the tube coupler and the bumper. A wedge assembly is connected to the launcher pipe and has a first actuating wedge and a first extension wedge. A first linear actuator is connected to the first actuating wedge and is configured to move the first extension wedge and the tube coupler mount apart from one another to position the tube coupler and the bumper from a retracted position to an extended position.
