Abstract
Abstract A combination of at least one pipe and a plurality of clamping members for construction a pipeline. The pipe includes a plurality of diametrically deformed portions each having a partly circular cross section defining at least one recessed flat wall portion and a pair of shoulders located at the opposite ends, respectively, of the flat wall portion which are spaced apart from each other along the length of the pipe. The clamping members are spaced apart from one another along the pipe. Each clamping member is formed from a strip and is folded back at least at one end thereof to form a partly cylindrical wall fitted about one of the diametrically deformed portions of the pipe and held between the shoulders.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
138 words
A pipe and clamp combination for constructing a pipeline which comprises: at least one pipe having a generally circular cross section along a major portion of the length of said pipe, said pipe including at least one diametrically deformed portion having at least one recessed flat wall portion and a pair of shoulders located at opposite longitudinal ends, respectively, of said flat wall portion, said shoulders being spaced apart from each other along the length of said pipe; and a clamping member for each said diametrically deformed portion of said pipe, each said clamping member being formed from a strip, each of said clamping members being folded back at least at one end thereof to form at least one flat wall fitted about one of said diametrically deformed portions of said pipe and held between said shoulders thereof.
Claim 2
Dependent Claim
138 words
A pipe and clamp combination for constructing a pipeline which comprises: at least one pipe having a generally circular cross section along a major portion of the length of said pipe, said pipe including at least one diametrically deformed portion having at least one recessed flat wall portion and a pair of shoulders located at opposite longitudinal ends, respectively, of said flat wall portion, said shoulders being spaced apart from each other along the length of said pipe; and a clamping member for each said diametrically deformed portion of said pipe, each said clamping member being formed from a strip, each of said clamping members being folded back at least at one end thereof to form at least one flat wall fitted about one of said diametrically deformed portions of said pipe and held between said shoulders thereof.
Claim 3
Dependent Claim
52 words
