摘要： A header delivery system and method for performing a pigging operation on a process tube connected at an angle to a header pipe. The header delivery system includes a base assembly coupled to a rotation assembly. The base assembly has a frame member supporting a launcher pipe coupled to a tube coupler and a jack apparatus. The rotation assembly is configured to position the base assembly with respect to the rotation assembly to adjust an angular position of the base assembly. The header delivery system may be aligned with a process tube in the header pipe and the jack apparatus may position the tube coupler from a first retracted position to an extended position to form a seal between the tube coupler and the first process tube. A service operation may be performed on the first process tube with the tube coupler in the extended position.

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.
