Osmarender has been so kind as to include pipelines in its rendering rules. Unfortunately, there seems to be an issue with pipelines running through certain landuse=* areas.

Take a look at this: http://www.openstreetmap.org/?mlat=50.80511&mlon=6.16231&zoom=17&layers=O

The heat pipeline (underground, therefore tagged layer=-1) at the tip of the marker is displayed as a reddish, dotted line. Within the farmland cutting into the commercial area, the pipeline disappears. It reappears in the commercial area again (to the west) and just before the motorway (to the northeast), only to disappear again a few hundred meters further, when it enters another landuse=farmland.

The same happens with landuse=forest and landuse=cemetery. (Well yes, the course of the pipeline may still be a bit inaccurate or incomplete, but this ticket is only about the rendering...) With landuse=commercial, landuse=military and landuse=residential, there are no problems.

By the way, I understand that Osmarender's standard layout is not a specialized "infrastructure map", so things like pipelines should not appear too prominently - but maybe the (yellow) gas pipelines could be given a slightly stronger color anyway?
