  • Patent number: 9593794
    Abstract: A pig receiver and method retrieve pigs in pipeline pigging operations. In one embodiment, a pig receiver includes a pig receiver unit. The pig receiver also includes a pig gate valve assembly disposed on the pig receiving unit. The pig gate valve assembly includes a gate valve. The pig gate valve assembly also includes a first actuator and a second actuator. The pig gate valve assembly further includes a cylinder guide. In addition, the pig gate valve assembly includes a tie bar. Actuation of the tie bar actuates the gate valve. An end of the tie bar is attached to the first actuator, and an opposing end of the tie bar is attached to the second actuator. The pig receiver also includes a system for removing contaminants from the pig receiver.

  • Publication number: 20160195214
    Abstract: A pig receiver and method to retrieve pigs in pipeline pigging operations. In one embodiment, a pig receiver includes a pressure equalization system including a gate valve, wherein a first side of the gate valve is coupled to a downstream pressure connection, and wherein a second side of the gate valve is coupled to an upstream pressure connection. The pressure equalization system also includes a pressure equalization valve disposed between the downstream pressure connection and the upstream pressure connection. The pressure equalization system also includes a pig receiver unit, wherein a first side of the pig receiver unit is coupled to the downstream pressure connection downstream of the gate valve, and wherein a second side of the pig receiver unit is coupled to the upstream pressure connection upstream of the gate valve.
