Boiler tube shield

A tube shield for protecting a tube having an external diameter, said tube shield comprising:

• a plurality of semi-cylindrical shield members extending in a longitudinal direction having an internal diameter substantially equal to said external diameter of said tube and an external diameter, each of said shield members having a first and second end;
• a retaining means for retaining each of said shield members in contact with said tube;
• and
• a means to interlock each of said shield members to an adjacently positioned second shield member, wherein said first end of said first shield member has a longitudinally extending member which interlocks with a corresponding second longitudinally extending member of a second end of said second shield member together thereby maintaining a substantially continuous semi-cylindrical shield of substantially uniform thickness about said tube between two adjacent shield members along a length of said plurality of shield members.

A tube shield for protecting a tube having an external diameter, said tube shield comprising:

• a semi-cylindrical shield member extending in a longitudinal direction having an internal diameter substantially equal to said external diameter of said tube and an external surface, said shield having a first and second end;
• a plurality of flanges at least one longitudinally extending from each of said first and second ends, each of said flanges adapted to mate adjacent to a corresponding flange of a second shield member whereby when said flange mates with said corresponding flange each of said mating flanges is disposed exclusively on opposite portions of said tube thereby maintaining a substantially continuous semi-cylindrical shield between two adjacent shield members,
• a retaining means for retaining said shield member in contact with said tube;
• wherein,
• said flanges are formed such that when one end of said tube shield is secured to said tube adjacent to a second end of a second tube shield, said one end of said tube shield and said second end of said second tube are positioned continuously adjacent to one another to inhibit exposure of said tube.

• wherein,
• said flanges are formed such that when one end of said tube shield is secured to said tube adjacent to a second end of a second tube shield, said one end of said tube shield and said second end of said second tube are positioned continuously adjacent to one another to inhibit exposure of said tube, wherein said plurality of flanges comprises at least a pair of flanges one each disposed on both said first and second end, said pair of flanges being substantially formed as a mirror image of one another with respect to a plane intersecting an axis of said semi-cylindrical shield member which divides said tube shield in substantially two equal halves.

• a semi-cylindrical shield member extending in a longitudinal direction having an internal diameter substantially equal to said external diameter of said tube and an external surface, said shield having a first and second end;
• a plurality of flanges at least one extending from each of said first and second ends,
• a retaining means for retaining said shield member in contact with said tube;
• wherein,
• said flanges are formed such that when one end of said tube shield is secured to said tube adjacent to a second end of a second tube shield, said one end of said tube shield and said second end of said second tube are positioned continuously adjacent to one another to inhibit exposure of said tube, said retaining means comprises a securement strap extending between two ends wound about said tube and one of said flanges.
