Problems solved by technology

[0003] However, the known pipes have the disadvantage that the sealing element can slip out of the separation point, thereby causing a leak
This increases assembly costs
Furthermore, liquid or gaseous toxic media may escape during operation of the plant including the pipeline and may constitute a hazard for the plant user

Embodiment Construction

[0024] figure 1 Shows a cross-sectional view of the end of a pipe. in figure 1 The cross-sectional view shown in may refer to the end of a straight or curved pipe or may refer to a T-piece, a Y-piece, a four-branch pipe, a six-branch pipe, or other components known per se for constructing a pipe network Single joint.

[0025] The pipe 10 has a longitudinal section 13 with a substantially constant wall thickness and a parallel outer contour. The longitudinal section 13 is either used to convey the fluid flowing in the interior of the pipe 10 in a straight line or to transfer the figure 1 The end joint shown in is adapted to one of the pipe elements described above.

[0026] The first longitudinal section 13 merges into the support 100 with a second longitudinal section 16. The inner wall and / or outer wall of the second longitudinal section 16 may be inclined outwards by a small amount relative to the first longitudinal section 13. This results in an expansion of the tube cross se...

Abstract

The invention relates to a pipeline (10) which has a pan (100) at at least one end, as part of a connecting system, wherein the pan (100) has an inner sealing surface and an outer sealing surface which are inclined inwards, and the inner sealing surface and the outer sealing surface are separated from one another by a step. The invention also relates to a sealing element (20) having a toroidal basic shape, in which the cross section has a first contact surface and a second contact surface with an upper face and a lower face, wherein the first contact surface is intended to rest on an outer face (14) of a pipeline (10), and the second contact surface is intended to rest on a sealing surface which is inclined in the direction of the pipe interior. Finally, the invention relates to a pipe connection (30) for connection of two pipelines (10) using a sealing element (20) such as this.

Description

Technical field [0001] The present invention relates to a pipe having a support as part of a connection system on at least one end; and the present invention relates to a sealing element having a ring-shaped basic shape. Pipes and sealing elements of the type mentioned at the beginning can be used, for example, in chemical process technology and / or in the pharmaceutical industry for conveying gaseous or liquid media. Background technique [0002] It is known from practice to have pipes with a sealing flange on at least one end, so that a plurality of pipes can be joined by the provided connecting element. In order to ensure the tightness of the connection part, a sealing element made of elastic material can be inserted between the sealing flanges of the pipeline. [0003] However, the known pipeline has the disadvantage that the sealing element may slip out of the separation location, thereby causing leakage. This increases assembly costs. In addition, liquid or gaseous toxic me...
