Trapp have provided management personnel and procured and delivered major pipe laying equipment for the onshore oil pipeline industry; most recently from 2004 for pipeline works associated with gas gathering for the Bonny Gas terminal in Nigeria.
Trapp have constructed pipeline and storage systems for Military and Civilian airports in the Yemen, Cameroun and Nigeria.
Trapp have installed fresh and waste water distribution systems for Townships in Nigeria from 1990 to 1994 including fire fighting pressure systems, lifting and pumping station ; and Large scale, large diameter Urban drainage systems in Aba, Nigeria from 1978 to 1981 and the Benin City Main Drainage Scheme Phase I, Nigeria from 1970 to 1973.
The sewerage system started at the turn of the century necessitated coordinated
installation of pipe systems. Trapp had their first experience in this
sector in 1910 when Wesel was provided with a modem sewage system. The
20th century also produced another use for pipelines - as a means of transporting
oil and other products.
Arising from the work as an earthworks company for pipelines in cooperation with pipeline specialists a few years ago was a new branch: Pipeline Construction. Trapp became members of "German Association for Gas and Water Specialists, Frankfurt".
The Berlin waterworks awarded the first important orders in this field to Trapp in 1969: laying Eternit and steel pipes 1.60 m (NW 1600) in diameter. In this work steel drains were built, the execution of which required a maximum of precision in pipe measuring, cutting and welding.
Trapp have been involved in pipeline construction continuously since March 1974. What had started with the construction of five large pipelines for the Gelsenkirchen ship's hoist was continued with the laying of cast water pipelines for Gelsenwasser via high-pressure gas lines up to DN 800 and PN 65 for Ruhrgas AG, for Thyssen gas as well as the water and gas supply of Dortmund University. Expansion of Trapp's business line sewage purification plant construction initiated a great deal of varied work for the team of pipeline builders.
Pipes with dimensions of up to DN 1600 in steel, stainless steel as well as PEHD have been laid. This was how the sewage purification plants of Dinslaken, Gevelsberg, Kleve, Siegen and Wesel as well as the Emsch Cooperative, the Lippe Association and the Ruhr Association were fed.
Trapp have had the highest number of permits from the German Association for Gas and Water Specialists, DVGW, for (Gl+pe,Wl+pe) and constructs pipelines for all pressure stages and media.
For municipal clients and industrial operations Trapp have executed numerous contracts in the sewerage field. Here pipes made of stoneware, concrete, spun concrete and Eternit were laid with nominal widths of 100 millimetres up to 4 metres for main sewers.
Due to the demand in PEHD pressure pipe lines growing, particularly in sewer pressure pipe lines, Trapp produce numerous pipelines up to DA 630, PN 10 as well as in steel DN 1200, reinforced-concrete pipes DN 1400 and extensive manhole and outfall structures. These construction projects were carried out in Bottrop, Dinslaken and Dortmund for the Emscher Cooperative/Lippe Association.
Another field of activity is waste dump construction. They are provided with infiltration water pipes (PEHD) DA 400 as well as dump gas lines and well systems, e.g. for the EDG Dortmund and the Ruhr Association.
Trapp concluded an acquisition agreement for disincorporation of LAUBAG on 1st July 1995. Subsequently the business sphere of LAUBAG pipe construction was incorporated into the Trapp group.
Trapp have had experience in pipe construction and pipe driving for some decades, making good use of it in the field of lignite mining. This take-over formed the start of a way to become active in other fields of business. This was described at the time by Dr.-Ing. Friedrich Carl Trapp as follows "We want to carefully continue the development begun in Lausitz and where possible realise our specialist know-how in fields where we have been working for decades, such as structural and civil engineering, construction engineering and.-road construction, as well as in realising all work for the environment and environmental protection."
