Piping for use as a pyrolysis tube in a cracking furnace, wherein the tube is formed such that it has at least one section whose centerline curves in three dimensions, to induce swirl flow in the tube. The tube can be formed as a helix.

Cracking furnace

The invention relates to piping for use as a pyrolysis tube in a cracking furnace. The tube is formed such that it has at least one section whose centreline curves in three dimensions, to induce swirl flow in the tube. Preferably, the tube is formed as a helix, more preferably a low-amplitude helix.

Piping

The present invention relates to piping () for use in industrial activities, where the piping () has a specific geometry. In particular, the piping () is formed as a lowamplitude helix, which causes fluid flowing through the piping () to swirl. This swirl flow provides a large number of advantages. Particular applications where the piping () can be used include petroleum production risers and flowlines, production tubing for downhole use in wells, pipelines for the transportation of fluids, static mixers, bends, junctions or the like, penstocks and draft tubes, reactors for chemical, petrochemical, and pharmaceutical applications, heat exchangers, cold boxes, incinerators and furnaces for waste disposal, static separators, and air intakes.

Olefin production furnace having a furnace coil

The invention relates to piping for use as a pyrolysis tube in a cracking furnace. The tube is formed such that it has at least one section whose centerline curves in three dimensions, to induce swirl flow in the tube. Preferably, the tube is formed as a helix.
