Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
87 words
A method of laying pipeline while insulating and supporting the pipe comprising the steps of placing a plurality of axially aligned inflated bag sections each having an axial recess shaped in cross-section similar to the cross-section of at least a portion of the pipe to be received therein, placing the pipe on said plurality of inflated bag sections in said recesses, placing a plurality of complementary inflated bag sections over the section of pipe and said first mentioned plurality of inflated sections, to thereby enclose said pipe.
Claim 2
Independent Claim
87 words
A method of laying pipeline while insulating and supporting the pipe comprising the steps of placing a plurality of axially aligned inflated bag sections each having an axial recess shaped in cross-section similar to the cross-section of at least a portion of the pipe to be received therein, placing the pipe on said plurality of inflated bag sections in said recesses, placing a plurality of complementary inflated bag sections over the section of pipe and said first mentioned plurality of inflated sections, to thereby enclose said pipe.
Claim 3
Dependent Claim
15 words
The method of claim 1 wherein said inflated sections are filled with an inert gas.
Claim 4
Dependent Claim
14 words
The method of claim 1 wherein said inflated sections are filled with carbon dioxide.
Claim 5
Dependent Claim
43 words
A pipe supporting and insulating member comprising: an elongated flexible inflatable bag member having a longitudinally extending recess in a surface thereof for receiving and supporting a longitudinally extending pipe in said recess and valve means in said member for inflating the same.
Claim 6
Dependent Claim
43 words
A pipe supporting and insulating member comprising: an elongated flexible inflatable bag member having a longitudinally extending recess in a surface thereof for receiving and supporting a longitudinally extending pipe in said recess and valve means in said member for inflating the same.
Claim 7
Dependent Claim
21 words
The covering of claim 4, further characterized by said air valve means having a valve in an indentation in said section.
Claim 8
Dependent Claim
56 words
The covering of claim 4, further characterized by said sections each having a semi-circular outer surface on the side away from the pipe, and a flat surface on a side opposite said outer surface extending between the edges of said outer surface and having a semi-circular groove extending longitudinally along said flat surface between said edges.
Claim 9
Dependent Claim
15 words
The covering of claim 4, further characterized by said inflated sections containing an inert gas.
Claim 10
Dependent Claim
14 words
The covering of claim 4, further characterized by said inflated sections containing carbon dioxide.
