Die Fehlerquote von ca. einhundert geröngten Schweißnähten betrug 0%. Aufgrund der guten Leistung wurde die IMR auch für die Revision von Block F für August 2013 bestellt.

Hochdruckrohrleitungsprojekt in Walsum erfolgreich abgeschlossen

High pressure piping project in Walsum successfully finished

February 2013: IMR has successfully finished an order for Modification of high pressure pipe works in the turbine building on the project Duisburg Walsum Unit 10 for the customer Hitachi Europe and under the Supervision of Hitachi Ltd. The order contains piping modification on systems like LBQ high pressure extraction steam material 1.7335 dimensions OD 700 x WT 30, OD 610 x WT 40, OD 457 x WT 10, LBC hot reheat steam piping material 1.5415 dimensions OD 273 x WT 14.2 and the LCH drain piping from high pressure heater material 1.7380 OD 273 x WT 20. The contract contains additionally the reinstallation and new installation of the isolation and the paint. The complete order has been worked out with personal of the IMR HAMBURG GmbH and her subsidiary companies in eastern Europe as well as own supervision with the welder failure rate of 0%.

Since 2010 it has been in the HP piping area on the pipeline projects Walsum10, CFPP GDF Suez Wilhelmshaven and Rotterdam built a total of about a thousand tons of high pressure piping spools plus LISEGA support erection success. Notable systems, partially prefabricated spools whose prefabrication have been increased in balanced erection by IMR assembly concept further, are HAD Auxiliary steam to Economizer 1.4903 273×28, MAA fresh steam to turbine 1.4901 519×108, MAB and MAP (NDU) Hot Reheat 1.4901 486×36 and 1.4903 914×16, and MAW gland steam and LAB feed water in different materials and dimensions.


Since the start of the CFPP Walsum unit 10 piping project in 2007 IMR was searching for a good solution to manage piping data within the work planning, material handling, erection and quality assurance phases. After some tests with other software it was found that INTERGRAPH provides already proven software within the SMART PLANT tool group

Interfaces for SAP and all 3D CAD software used in the business that run on Isogen or Isodraft files can be handled. To read some details of the software implementation process and experiences please feel free to follow this Link.

In CW04-2012 IMR continued to invest in workplace safety

In CW04-2012 IMR continued to invest in workplace safety. 20 extra men of the operational staff in theory and practice have been trained, tested and certified with the support of our partner GARDEMANN according to the IPAF guidelines as a lifting platform operator. Scissors and swivel arm manlifts (so called “cherry pickers”) are used in many areas and involve numerous risks. Through the observance of basic operating instructions, most hazards are reduced to virtually zero. Emergency lowering and other maneuvers were practiced by each participant which gives confidence in dealing with the devices.

IMR rebranded!

New IMR-Hamburg logo

New IMR-Hamburg logo

IMR rebranded! We see ourselves as piping specialists in northern Germany. Since for our customers we have long been known as “IMR from Hamburg” and as a now European wide operating company we wanted to strengthen our brand recognition with a name than can more easily be remembered from non German speaking people and still be present for our old customers. Therefore we are now working under the name “IMR HAMBURG GmbH” for you. On the 23rd of June 2011 the new company name was already registered in the commercial register of Hamburg with the number HRB 85504. Of course we are still accessible as usual with the existing telephone numbers, email and postal addresses. Also banking details remain unchanged.

In CW06-2011 the entire personal employed in the new building on CFPP Wilhelmshaven by IMR operational personal and executive staff where trained and tested in accordance with SCC Doc. 18 and 17. As a campaign for safe, healthy and environmentally sound work aims IMR in continuous improvement under this years motto of our BG (work insurance) “Stop Accidents”.

The photos show the training, which was translated in three languages and the training participants in strengthening and one of the Doc. 18/17 test groups separated by language and tasks.

The testing and certification was carried out by representatives of the KIWA and was organized by

Big step towards HP done!

In CW50-2010 efforts to continuous improvement and development of IMR’s welding technology culminated after several processes checks and reference annealing now in the successful and timely completion of the first “P92” weld in manual TIG/E process within the new coal fired power plant Wilhelmshaven for Electrabel Gas de France Suez with the dimensions of outer diameter 570 x wall thickness 75 [mm ]. Figure 1 shows one of our HD-welder at important measuring of the pipes inner misalignment.

After a well deserved Christmas break of our HD pipeline welders was in KW02-2011 now run the second weld of excellent quality. Figure 2 gives an impression of the welding task.

The ultrasound examinations in CW01-2011 of the first and in CW03-2011 of the second weld confirmed the standard conform welding of the welds under the supervision of our customers from Duisburg and of the Notified Body TUEV Rheinland. The UT Inspector our business partner Pockrandt, Oberhausen can be seen in Figure 3 during its audit work.

IP LP piping package Rotterdam ordered

In December, 2009 the order was given to IMR for manufacturing and erection of IP, LP and partial HP piping systems of the project „New building of KW Rotterdam Electrabel EBL2 “. The customer Hitachi Power Europe GmbH (HPE) from Duisburg builds there essential components of the new 800 MW coal power plant for the belgian energy provider Electrabel.

The order contains in the main focus pipes in the machine house with e.g. HP turbine-connections for extraction steam system LBQ, as well as auxiliary system LBG and various media there and in the boiler house as well as in the media wing. Besides classical, low and higher alloyed pipes within the HP part P91 (1.4903) OD 914 x thickness 16, P92 (1.4901) OD 570 x thickness 75 and WB 36 (1.6368) OD 273 x thickness 10 are to be welded as material.
