Insulated riser clamp

1. A riser clamp assembly adapted for receiving and supporting an insulated pipe, said assembly comprising:

a first riser clamp, and

a second riser clamp;

wherein each of said riser clamps comprises:

a semi-circular body portion extending arcuately between opposite first and second ends and defining an inner cylindrical wall and an outer cylindrical wall extending axially between top and bottom edges,

wherein said semi-circular body portion includes a generally C-shaped metal body,

a generally C-shaped flange projecting radially from said inner cylindrical wall generally midway between said top and bottom edges to define an axial center opening,

wherein said C-shaped flange extends radially more than it extends axially and said C-shaped flange extends from said first end to said second end,

said C-shaped flange includes a generally C-shaped metal flange extending radially inwardly from said C-shaped metal body,

said C-shaped metal body and said C-shaped metal flange are overmolded with plastic, and

said C-shaped metal flange includes a plurality of spaced apart axial through-holes for mechanically bonding said plastic with said C-shaped metal flange, and

a support brace extending radially from said outer cylindrical wall adjacent each end of said body portion for interconnecting said first and second riser clamps around the insulated pipe,

wherein the C-shaped metal body extends arcuately between opposite ends defined by said support brace.

2. The riser clamp assembly as set forth in claim 1 wherein each of said support brace includes a bore therethrough for receiving a fastener for interconnecting said first and second clamp around the insulated pipe.

3. A riser clamp assembly adapted for receiving and supporting an insulated pipe, said assembly comprising:

a first riser clamp and

a second riser clamp;

wherein each of said riser clamps comprises:

a semi-circular body portion extending arcuately between opposite first and second ends and defining an inner cylindrical wall and an outer cylindrical wall extending axially between top and bottom edges;

a generally C-shaped flange projecting radially from said inner cylindrical wall generally midway between said top and bottom edges to define an axial center opening wherein said flange extends from said first end to said second end; and

a support brace extending radially from said outer cylindrical wall adjacent each end of said semi-circular body portion for interconnecting said first and second riser clamps around the insulated pipe; and

wherein said semi-circular body portion includes a generally C-shaped metal body extending arcuately between opposite ends defined by said support brace extending radially from said body,

said C-shaped flange includes a generally C-shaped metal flange extending radially inwardly from said C-shaped metal body,

said C-shaped metal body and said C-shaped metal flange are overmolded with plastic, and

said C-shaped metal flange includes a plurality of spaced apart axial through-holes for mechanically bonding said plastic with said C-shaped metal flange.

4. The riser clamp assembly as set forth in claim 3 wherein each of said support brace includes a bore therethrough for receiving a fastener for interconnecting said first and second clamp around the insulated pipe.

5. In combination, a riser clamp assembly and an insulated pipe:

said riser clamp assembly comprising:

a first riser clamp, and

a second riser clamp; wherein

each of said riser clamps including a semi-circular body portion extending arcuately between opposite first and second ends and defining an inner cylindrical wall and an outer cylindrical wall extending axially between top and bottom edges,

wherein said semi-circular body portion includes a generally C-shaped metal body,

a generally C-shaped flange projecting radially from said inner cylindrical wall generally midway between said top and bottom edges to define an axial center opening, wherein

said C-shaped flange extends from said first end to said second end,

said C-shaped flange includes a generally C-shaped metal flange extending radially inwardly from said C-shaped metal body,

said C-shaped metal body and said C-shaped metal flange are overmolded with plastic,

said C-shaped metal flange of said metal bracket includes a plurality of spaced apart axial through-holes for mechanically bonding said plastic with said C-shaped metal flange, and

a support brace extending radially from said outer cylindrical wall adjacent each end of said body portion for interconnecting said first and second riser clamps around said insulated pipe,

wherein the C-shaped metal body extends arcuately between opposite ends defined by said support brace;

said insulated pipe comprising:

a pipe,

a first insulation tubing encased around said pipe and extending longitudinally between opposite ends, and

a second insulation tubing encased around said pipe and extending longitudinally between opposite ends;

wherein each of said riser clamps is positioned in mating engagement surrounding said pipe and said pipe extends through said axial center openings, and

wherein facing ends of said first and second insulation tubings are inserted into said body portions surrounded by said inner cylindrical walls and abutting opposite sides of said flanges.

6. The combination as set forth in claim 5 wherein each of said support brace includes a bore therethrough for receiving a fastener for interconnecting said first and second clamp around said insulated pipe.
