A method for joining at least two plastic elements in a liquid- and/or gastight manner, whereby an edge of a first plastic element is at least partially placed in an opening of a second plastic element, the edge of the first plastic element being folded over an edge of the opening of the second plastic element under plastic deformation, using a pressure device. The edge of the first plastic element is pressed against a curved butting face of a pressure body placed in the second plastic element at the opening thereof and the edge of the first plastic element along the butting face is pushed radially outwardly and over the edge of the opening of the second plastic element. The edges of both plastic elements are pressed together by exerting pressure on both sides of the edges. Alternatively, use is made of a sealing ring at least partially between the edges.
A method for joining at least two plastic elements in a liquid- and/or gastight manner, comprising placing an edge of a first plastic element at least partially in an opening of a second plastic element, folding the edge of said first plastic element over an edge of said opening of the second plastic element under plastic deformation, using pressure means, wherein said first plastic element is pressed against a curved butting face of a pressure body placed in said second plastic element at the opening thereof and being supported independently therefrom such that said edge of said first plastic element is pushed radially outwardly and over said edge of the opening of said second plastic element, pressing together said edges of both plastic elements to form a joint, and exerting pressure on both sides of the joint using a pressure element and a pressure body which cooperate with each other to thereby form a liquid and/or gastight joint.
A device for joining at least two plastic elements in a liquid- and/or gastight manner including a first pipe-like member and a second pipe-like member where the second pipe-like member includes an opening therein and the first pipe-like member is positioned with one end at least partially disposed in said opening in said second pipe-like member, said device comprising a pressure body disposed within said opening in said second pipe-like member and being supported independently therefrom, a pressure element positionable with respect to said first pipe-like member such that an axially directed force can be imparted on said first pipe-like member by movement of said pressure element in the direction of the axis of said first pipe-like member, means for pushing an abutting edge of the first pipe-like member against a curved butting face of said pressure body placed in said second pipe-like member at the opening thereof so that the abutting edge of said first pipe-like member is pushed radially outwardly as a result of an edge of the opening of said second pipe-like member being clamped between edges of said first pipe-like member, and means for pressing said edges of said first and second pipe-like members together to form a joint.
A device for joining at least two plastic elements in a liquid- and/or gastight manner including a first pipe-like member and a second pipe-like member where the second pipe-like member includes an opening therein and the first pipe-like member is positioned with one end at least partially disposed in said opening in said second pipe-like member, said device comprising a pressure body disposed within said opening in said second pipe-like member, a pressure element positionable with respect to said first pipe-like member such that an axially directed force can be imparted on said first pipe-like member, by movement of said pressure element in the direction of the axis of said first pipe-like member, means for pushing an abutting edge of the first pipe-like member against a curved butting face of said pressure body placed in said second pipe-like member at the opening thereof so that the abutting edge of said first pipe-like member is pushed radially outwardly as a result of an edge of the opening of said second pipe-like member being clamped between edges of said first pipe-like member, and further including means for pressing said edges of said first and second pipe-like members together to thereby form a joint, and wherein said means for applying said axially directed force is a piston assembly which is movable along a path coaxial with said second pipe-like member and engages a rod fixed to said pressure element to move said pressure element along a path coaxial with said first pipe-like member.
