METHOD OF USING A PIPE COUPLING HAVING MOVABLE GRIPPING BODIES |
摘要 |
A method of joining pipe elements in end to end relation includes using a coupling having two or more segments connected to one another end to end surrounding a central space. The coupling also has at least one gripping body positioned between two of the segments. The pipe elements are inserted into the central space. The segments and the gripping body or bodies are moved toward the central space. The segments have arcuate surfaces which engage the outer surface of the pipe element. The gripping body or bodies have gripping surfaces which engage the outer surface of the pipe elements.
