Abstract: A tube support device is an assembly of a male member and a female member. The male member has a seat section and a prong section. The female member has a seat section and a receiver section having a channel therein. The prong section of the male member slides into the channel in the receiver section of the female member. The device can be made of cast alloy steel. The device can be used in a system for providing lateral and longitudinal alignment support and spacing for tubes, especially at an intersection of a horizontal tube and a vertical tube.

Abstract: A system for supporting horizontal boiler tubes comprises a support plate, a vertical stringer tube, and a shear lug. The shear lug attaches the support plate to the vertical stringer tube through a slot in the support plate. A plurality of supporting arms extend outwardly from the first and second sides perpendicular to a main body portion of the support plate. Each supporting arm includes a retaining lip extending upwardly from a distal end of the supporting arm and a rounded recess, the rounded recess and retaining lip defining a cradle within which a horizontal boiler tube may rest.
