  • a circulating device ( 6 ) is preferably a propeller involving a slow rotary speed.
  • the method proposed here is basically not limited in respect of the material and the structural form of the pipes ( 1 ) to be coated, but the method is deemed primarily and thus preferably as adapted for coating pipes ( 1 ) of mild steel which quite particularly preferably are longitudinally welded.
  • their possible length (L) with the method proposed here is firstly exclusively limited by the length of the immersion basin ( 2 ), lengths (L) of up to 12 m are preferred, further limitedly preferred between 7 and 12 m and quite particularly preferred of a length (L) in a range of 7 m to 10 m.
  • those pipes ( 1 ) within a first preferred range are of a nominal width (n) of DN 32 to DN 250 , which in the context of use of fire protection installations corresponds to the usual pipe nominal widths of the main conduit, for example in the form of riser conduits, by way of possible secondary distribution pipes, for example in the form of distributor conduits, as far as the sprinkler connection pipes, for example in the form of branches (branch lines).
  • a range of DN 32 to DN 65 is deemed to be quite particularly preferred, which in the context of the use of fire protection installations corresponds to the pipe nominal widths of usual secondary distribution pipes as far as the sprinkler connection pipes.

  • a plurality of pipes ( 1 ) are simultaneously subjected to method steps (ii.) to (vi.) it is deemed to be preferred if the bar-like support holders of that kind are parts of an immersion frame.
  • the immersion frame together with the bar-like support holders then permits simultaneous coating of a plurality of pipes ( 1 ) which in that case are arranged in mutually juxtaposed and/or superposed relationship during the coating operations.
  • the bar-like support holders and/or the immersion frame are Teflon-coated, which applies in particular when the coating liquid ( 3 ) is in the form of an epoxy/acrylic-based AquenceTM coating material.
  • the disclosure also concerns pipes ( 1 ) produced in accordance with the method proposed here, wherein such pipes ( 1 ) have an outside and an inside anti-corrosion coating.
  • anti-corrosion coating is an epoxy/acrylic-based AquenceTM coating.
  • That coating is quite particularly preferably such that the coating on the pipes ( 1 ) both externally and also internally is of a layer thickness in the preferred range of 15 to 28 ⁇ m, quite particularly preferably in a range of 21 to 27 ⁇ m.

  • Ensuring a value for C in a range of 125 to 150, on the basis of an internally disposed corrosion protecting coating of such a configuration, provides for completely even and non-porous sealing means of the insides of the pipes ( 1 ), which no longer has the extinguishing medium carried by the pipes ( 1 ) infiltrating therebeneath even over many years, which applies even for the ends of the pipes ( 1 ), that are brought together in the couplings.
  • the pipes ( 1 ) produced in accordance with the method proposed here are practically unlimited in respect of their nominal size, in particular and preferably the pipes ( 1 ) should involve a nominal width (n) in a range of DN 32 to DN 250 , which corresponds to the usual pipe nominal widths within the fire extinguishing systems which are particularly favoured as the application thereof from the main conduit, for example in the form of riser conduits, by way of possible secondary distribution pipes, for example in the form of distributor conduits, as far as the sprinkler connection pipes, for example in the form of branches (branch conduits).
