ABSTRACT:
A containment device provides containment for a pipe and includes a containment body having a first end section and a second end section. The containment body has an open interior that defines a channel configured to receive the pipe therein. First and second closures are configured to close an entrance of the first end section and an exit of the second end section, respectively, about the pipe. The containment body may be configured to receive therein a pipe leading from a cement pump truck. The first end section is suitably configured to receive therein a cement pump outlet pipe. The second end section is suitably configured to receive therein a cement delivery tube. A middle section interposed between the first end section and the second end section is suitably configured to receive therein a transition section of pipe between the cement pump outlet pipe and the cement delivery tube.
