Zusammenfassung:Well fluid containment devices and methods. A housing may be provided for positioning around a pipe. A pipe gripping surface or grappler may be mounted to the housing. The pipe gripping surface resists movement when contacted in a first axial direction. The pipe gripping surface may permit movement when contacted in a second axial direction opposed to the first direction. The pipe gripping surface may, when contacted with a first force in a first axial direction, resist movement with an opposing force that increases as the first force increases. There may be a pressure relief connector between housing sections.
