A pipe rack system and a multi-plane coupling for such a pipe rack system are provided. The multi-plane coupling includes a coupling body that forms at least a first receiver aligned with a first axis, a second receiver aligned with a second axis, and a third receiver aligned with a third axis. The pipe rack system includes pipe sections that are received and coupled in the receivers. The multi-plane coupling may be in the form of a three-way, four-way, five-way, or a six-way pipe fitting. The receivers may be female threaded sockets. The pipe sections may be threaded pipe that are threadedly received within the female threaded sockets of the pipe fittings.
