The single pipes are divided into the following subgroups:
Series 1, 2,3 and 4 with dimensions Dn25/90 – Dn1000/1200. The steel pipes are longitudinally or spirally welded and can in most cases withstand 25 bar. The insulation consists of hard polyurethane foam with good thermal insulation, good mechanical properties and good aging resistance. All pipes are delivered in standard with Nordic alarm system.
Series 1, 2, 3 and 4. Pipes for cutting are manufactured for all dimensions. In these pipes, every other meter of the steel pipe is covered with foil, so that the insulation material can be easily removed. The parts that are provided with foil are clearly marked on the outside of the jacket pipe. Entire cutting pipes or parts of cutting pipes can be mounted at any place in the system.
Series 1, 2,3 and 4. Bended pipes are made of seamless or longitudinally welded steel pipes. Dn400 - Dn700 is also manufactured in increased wall thickness. Increased thickness with regard to other dimensions allows the maximum angle above to be increased.
Our twin pipes are usually laid with the inlet supply pipe at the bottom.
Twin pipes are available in series 1, 2 and 3.
Regarding the specification of the steel pipes, the insulation and the outer jacket, the requirements are the same as for single pipes. For twin pipes there are just as for single pipes, zebra and bended pipes.
We use proven technology when it comes to material selection, production and installation. All works are done at our factory, without any sub-contractors – this helps us guarantee high quality.
Raw material undergoes a thorough inspection in accordance with our quality system ISO 9001 and they are EHP certified by RISE and QB19 certified by CSTB.
