ABSTRACT:
A multiple activation-device launching system for a cementing head comprises a launcher body and at least one launching chamber that are sized to receive one or more activation devices therein. The activation devices are launched into the principal process-fluid stream inside the cementing head, and may be darts, balls, bombs, canisters and combinations thereof. The launching chambers are in fluid communication with an external power source for launching the activation device into the principal process-fluid stream.
