Method for producing pipe assembly and pipe assembly

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 , ...

Problems solved by technology

The disadvantage of such a pipe assembly is that the weld seams of the pressurized pipe assembly must then be laboriously post-processed and inspected
