HOBAS Pipe Systems for Air Treatment Industry
Carbon Dioxide Pipeline
Within the paper and plastic industry Carbon Dioxid is used for the manufactoring process. The gas will transported with HOBAS pipes, which can be tailored for the challenging chemical conditions. The HOBAS pipes do have an advantage to other types, because they are easy to handle, install and have many options to be combined with other materials.
Lean Gas Pipeline:
During the Paper production process, lean gas consisting of air, water vapor, volatile organic compounds, SO 2 and SO 3 is released. These gases then undergo thermal treatment. When selecting the pipe material, the low pH and high temperature (90°C) of the gas therefore had to be taken into consideration. In addition, the pipes also have to be UV resistant as most of the pipeline runs outside the factory building.
HOBAS Industrial Pipes are corrosion resistant and thanks to the use of a UV-resistant resin ideal for this lean gas pipeline. We supplied a total of 140 m DN 700, PN 2.5 pipes in sections prefabricated at the factory, which were then joined on site with hand lay-up laminate.
The old pipeline was removed and the new one in- stalled. Confined space and a working height of up to 15 m were considerable challenges for the laminating work on site. As construction also had to be carried out while the plant was in operation and keeping to a very tight schedule, careful planning and efficient project management were extremely important here. Due to an unexpected accident at the plant, the construction work had to be completed as quickly as possible. Instead of taking three weeks as origi- nally planned, the fitters and project managers worked so efficiently that the HOBAS Team managed to finish the job within 16 days – and the lean gas pipeline went back into operation earlier than hoped. Top quality, innovative products and pro- fessional installation on site: HOBAS again showed great expertise in industrial pipeline construction in this project.
