Pipeline engineering


Bitumen flare refinery

June 2013: Work begins on the assembly of the 70 m tall gas flare in a final work step on the refinery grounds. The object is divided into 3 flame elements, each weighing up to 40 tonnes, that need to be joined with extreme precision. 2 months of meticulous planning and 2 months of complex welding in the plant 
in Aschaffenburg preceded this work step. In the following 4 weeks the assembly team at Bick + Letzel GmbH mounted the flares and handed over the finished system to the operator punctually for commissioning. Bick + Letzel GmbH managed to complete this process within 7 months.



Bick + Letzel GmbH offers the entire range of classic pipeline engineering from one source; be it the design, dimensioning, construction, stability calculations including supports, or the general production of pipeline systems. Our certified quality standards also allow the production of systems subject to mandatory monitoring e.g. in the nuclear technology, the Pressure Equipment Directive 97/23/EC or the Water Resources Act fields. Our services also include stipulated pressure tests and non-destructive testing. We are able to manufacture pipeline systems of any size, and we have experience in working with austenitic, ferritic, high-temperature and duplex steel materials. Thanks to our experienced and flexible team, we can offer punctual solutions at short notice.
