Effluent containment device

摘要

Disclosed is a disposable drain device for containing seepage from a pipe-joint coupling as the coupling is broken open. The drain device has a wrap member made of a sheet material sufficiently pliant to be wrapped around the circumference of the pipe-joint coupling and resistant to the seepage composition. A drain means is disposed on the wrap member, having a drain port passing through the surfaces of the wrap member and a drain neck. The drain neck is disposed to direct seepage out of the installed wrap member. After use, the drain device can be disposed of as solid waste, rather than needing to be cleaned if the seepage was a hazardous material. The drain device being “disposable” allows the avoidance of creating an additional hazardous waste stream.

1. A disposable drain device for containing seepage from a pipe-joint flange coupling, the device comprising:
a wrap member, made of a pliant sheet material, having two parallel axial edges and two parallel circumferential edges that form a rectangle, sufficiently proof against leakage when exposed to the seepage and sufficiently pliant to be wrapped around the circumference of the pipe-joint flange coupling, and configured to contain seepage upon separation of the pipe-joint flange coupling therein; an axial closure mechanism, extending along the length of one axial edge, configured to close by having a first the axial edge of the wrap member overlap a second axial edge of the wrap member when the wrap member is installed over the pipe-joint flange coupling; a radial closure mechanism adapted to seal each circumferential edge against an outer pipe surface on each side of the pipe-joint flange coupling to define a seepage containment space; and a drain, disposed on the wrap member, having a drain port passing through the surfaces of the wrap member and a drain neck in flow communication with the drain port, the drain neck disposed to direct seepage out of the installed wrap member.
