Embodiment Construction

[0027] exist figure 1 A sectional view of a pipe 1 and a nipple 2 is shown in , wherein the pipe 1 and the nipple 2 have a pipe center axis 3 and are oriented on this pipe center axis.

[0028] The pipe 1 has a pipe outer surface 4 , a pipe end face 5 and a pipe outer diameter 6 . Furthermore, the pipeline 1 is constructed according to the presets regarding the tube length and the tube curvature, wherein the figure 1 A straight pipe is used in the illustration 1.

[0029] The nipple 2 has a nipple inner diameter 7 and has a flange section 9 with a flange section end face 8 and a pipe section 11 with a pipe section inner surface 10 . Grooves 12 for partially accommodating seals 13 (not shown here) are formed in the flange section end face 8 of the flange section 9 .

[0030] The seal 13 is preferably designed as a flat seal, wherein, as sealing material, materials such as elastomers, pressed fibers, aramid fibers, carbon fibers, mineral fibers, metals, copper are available f...

Abstract

The invention relates to a method for producing a pipe assembly (21) and to a pipe assembly (21) on which the method can be carried out, comprising two pipe units (16) having a pipe central axis (3), the invention relates to a pipe unit (16) comprising a pipe (1) having a pipe outer surface (4), a pipe end face (5) and a pipe outer diameter (6), and a pipe nipple (2) having a pipe nipple inner diameter (7), which has a flange section (9) having a flange section end face (8) and a pipe section (11) having a pipe section inner surface (10), the invention relates to a pipe assembly (1) for a pipeline (1), comprising a seal (13) arranged axially between flange section end faces (8) of a pipe connection sleeve (2) and a tensioning device (24) for axially tensioning flange sections (9) of the pipe connection sleeves (2) of two pipe units (16) against each other, the pipe connection sleeve (2) being inserted onto the pipeline (1) at least until the flange section end faces (8) are flush with the pipeline end faces (5), and the flange sections (9) of the pipe connection sleeves (2) being inserted into the pipeline (1) at least until the flange section end faces (8) are flush with the pipeline end faces (5). According to the invention, the pipe (1) is fixed in the pipe connection sleeve (2) by means of a press-fit (17) resulting from the radial expansion of the pipe (1), and the resulting pipe unit (16) is axially tensioned by tensioning a flange section (9) of the pipe connection sleeve (2) to form a pipe assembly (21).

Description

technical field [0001] The present invention relates to a method for manufacturing a pipe assembly comprising two pipe units having a central axis of the pipe, wherein the pipe unit comprises a pipe having a pipe outer surface, a pipe end face and a pipe outer diameter and a pipe nipple A pipe nipple with an inner diameter having a flange section with an end face of the flange section and a pipe section with an inner surface of the pipe section, the pipe assembly has a nipple arranged axially on the pipe nipple. A seal between the end faces of the flange sections and a tensioning device for axially tensioning the flange sections of the nipples of the two pipe units against each other. [0002] Furthermore, the present invention relates to a pipe assembly comprising two pipe units having a central axis of the pipe, wherein the pipe unit comprises a pipe having a pipe outer surface, a pipe end face and a pipe outer diameter and a pipe nipple with a pipe nipple inner diameter , ...
