Pipeline assembly and manufacturing method therefor

A pipeline assembly, comprising:

• a. at least one malleable sheet with two first edges opposite to one another;
• and
• b. an interlocking means capable of clamping said first edges of said sheet to each other resulting in a tubular body, wherein said interlocking means consists of a tongue and groove joint, wherein a tongue is formed at one of said first edges and a groove is formed at the other of said first edges,
• characterized in that said tongue is partially split, such that said split portion of said tongue is selectively compressible for entering in or exiting said groove and is configured to form a hole between said tongue and said groove in a length direction of said tubular body when said tongue and said groove are clamped to one another, wherein said hole is capable of receiving a liquid plastic, adhesive material or an electrofusion component.

A method for manufacturing a pipeline assembly, comprising the steps of:

• bending at least one malleable sheet to form an arc-shaped profile member;
• and
• clamping two first edges of said sheet to one another by means of an interlocking means to form a tubular body, wherein said interlocking means consists of a tongue and groove joint, wherein a tongue is formed at one of said first edges and a groove is formed at the other of said first edges,
• characterized in that said clamping said first edges includes:
• a. forming a hole between said tongue and said groove in a length direction of said sheet, wherein said tongue is partially split, such that said split portion of said tongue is selectively compressible for entering or exiting said groove and configured to form said hole when said tongue is clamped and said groove are clamped to one another;
• and
• b. introducing a liquid plastic, adhesive material or electrofusion component through said hole.

A pipeline assembly, comprising:

• a. at least two malleable sheets;
• and
• b. an interlocking means capable of clamping at least one of two first edges of one of said sheets to a corresponding edge of an adjacent sheet resulting in a tubular body, wherein each interlocking means consists of a tongue and groove joint, wherein a tongue is formed at one of two edges clamped by means of the interlocking means and a groove is formed at the other of said clamped edges,
• characterized in that each tongue is partially split, such that said split portion is selectively compressible for entering or exiting said groove and is configured to form a hole between said tongue and said groove in a length direction when said tongue and said groove are clamped to one another, wherein said hole is capable of receiving a liquid plastic, adhesive material or an electrofusion component.

A method for manufacturing a pipeline assembly, comprising the steps of:

• i. bending at least one first malleable sheet to form an arc-shaped profile member;
• and
• ii. clamping two first edges of said first arc-shaped profile member to corresponding first edges of a second sheet by means of two interlocking means to form a tubular body, wherein each interlocking means consists of a tongue and groove joint, wherein a tongue is formed at one of two edges clamped by means of said interlocking means and a groove is formed at the other of said clamped edges, characterized in that said clamping said first edges includes:
• a. forming a hole between a tongue and a groove of each tongue and groove joint in a length direction of said sheet, wherein each tongue is partially split, such that said split portion is selectively compressible for entering or exiting said groove and is configured to form a hole between said tongue and said groove in a length direction when said tongue and said groove are clamped to one another;
• and
• b. introducing a liquid plastic, adhesive material or electrofusion component through each hole.

A method for manufacturing a pipeline assembly, comprising the steps of:

• i. bending at least two malleable sheets to form two arc-shaped profile members;
• ii. clamping at least one bracket between said first arc-shaped profile members by means of multiple interlocking means to form at least two interconnected tubular bodies, wherein each interconnecting means consists of a tongue and groove joint, wherein one of tongue and groove of each interconnecting means is formed at an edge of one of said sheets, while the other of said tongue and groove is formed at an edge of said bracket corresponding to said edge of other of said sheets, characterized in that said step of clamping said bracket includes:
• forming a hole between a tongue and a groove of each tongue and groove joint in a length direction of said sheet, wherein each tongue is partially split, such that said split portion is selectively compressible for entering or exiting said groove and is configured to form a hole between said tongue and said groove in a length direction when said tongue and said groove are clamped to one another;
• and
• introducing a liquid plastic, adhesive material or electrofusion component through each hole.

An interlocking means for clamping two edges, comprising:

• a. a tongue formed at one of said edges;
• b. a groove formed at the other of said edges;
• and
• c. a sealing component for sealing said edges,
• characterized in that said tongue is partially split, such that said split portion of said tongue is selectively compressible for entering in or exiting said groove and is configured to form a hole between said tongue and said groove in a length direction of said edges when said tongue and said groove are clamped to one another, wherein said hole is capable of receiving said sealing component.
