Benefits of technology

[0005]It is therefore the object of the present invention to provide a pipe coupling, a pipe, designed to be connected to a further pipe by way of a pipe coupling, a pipe union, a method for introducing lubricant, and a method for producing a pipe coupling, which eliminate the drawbacks of the related art, and which in particular enable improved stability and strength of the pipes, in particular with respect to the internal pressure during operation.

Problems solved by technology

The walls of the pipes are thus not impaired, so that the structure thereof can be maintained or does not have to be additionally reinforced, which may result in oversized dimensioning.

Embodiment Construction

[0039]In the various figures, identical parts are always denoted by the same reference numerals and therefore are generally only cited or mentioned once.

[0040]FIGS. 1 to 4 schematically show a pipe coupling 1 according to an exemplary embodiment of the present invention. FIG. 1 shows a side view of the pipe coupling 1. FIG. 2 shows a top view onto the pipe coupling 1. FIG. 3 shows a perspective view of the pipe coupling 1. FIG. 4 shows an enlarged detail of the pipe coupling 1.

[0041]The pipe coupling 1 can be made of steel, in particular stainless steel, or GFRP. The pipe coupling 1 has a circular ring shape and extends along the longitudinal axis X thereof, the lateral direction Y perpendicular to the longitudinal axis X, and the vertical direction Z perpendicular to the longitudinal axis X and to the lateral direction Y. In the present embodiment, the pipe coupling 1 has three injection outlets 2, 3, 4. The pipe coupling 1 accordingly has three openings in the wall 5 thereof, in w...
