    摘要: A cap assembly for sealing the open end of a well casing or other pipe includes a top plate for mounting on the open end of the pipe, a bottom plate spaced apart from the top plate, an upper expansible gasket sandwiched between the top plate and an upper clamping plate, a lower expansible gasket sandwiched between the bottom plate and a lower clamping plate, spacer sleeves extending between the clamping plates, bolts through the bottom plate, both gaskets and clamping plates, the sleeves and the top plate, and nuts on the bolts. When the bolts are tightened on the nuts, the gaskets expand to seal the pipe at spaced apart locations.
