In a secondary containment system for storage and delivery of environmentally hazardous gases or liquids, a flexible boot mounted in a sump wall for supporting a pipe passing through a sump wall opening, comprising:
- a flexible annular member having a flange surface disposed against the sump wall exterior,
- a pipe engaging section extending from the flange of the flexible annular member through the opening in the sump wall to the sump interior, said flexible annular member and said pipe engaging section in combination being flexible to permit angular displacement from perpendicular of a pipe engaged within the boot and passing through the sump wall up to at least thirty degrees in any direction,
- said flexible annular member comprising a plurality of bolts disposed around the flange of the annular member and projecting into the sump interior from the flange surface of the annular member that is disposed against the sump wall, each of said bolts comprising a head that is encapsulated within the flexible annular member to protect said bolt heads from exposure to external environments.
In a secondary containment system for storage and delivery of environmentally hazardous gases or liquids, a flexible boot mounted in a sump wall for supporting a pipe passing through a sump wall opening, comprising:
- a flexible annular member having a flange surface disposed against the sump wall exterior,
- a pipe engaging section extending from the flange of the flexible annular member through the opening in the sump wall to the sump interior, said flexible annular member and said pipe engaging section in combination being flexible to permit angular displacement from perpendicular of a pipe engaged within the boot up to at least thirty degrees in any direction,
- said flexible annular member comprising a means for securing said annular member to said sump wall disposed at intervals around the annular member and projecting into the sump interior from the flange surface of the annular member that is disposed against the sump wall, said securing means having a first end encapsulated within the flexible annular member that is disposed on the sump exterior to protect said first end of the securing means from exposure to external environments, and a second end projecting from said encapsulated first end through the sump wall into the sump interior.
