Overhauls & Repairs of Turbo Expanders Maintenance Partners has a broad experience in overhauling and repairing turbo expanders: Single stage radial and axial turbo expanders Multi stage axial turbo expanders Single stage axial turbo expander wheels directly connected to axial compressor – can be in combination with an abradable sealing upgrade to the compressor for increasing efficiency These turbo expanders are utilised in the following applications: Chemical and petrochemical industries Fluid Catalytic Cracking (FCC) Residue Fluid Catalytic Cracking (RFCC) Nitric Acid Acetic Acid Terephtalic acid, or PTA Natural gas and oil industry Pipeline pressure reduction LNG, LPG Liquefaction of methane Coal gasification and hydration General industrial power recovery for example blast furnace top gas expansion Turbo Expander Activities Our services on turbo expanders include: Standard minor inspections Full comprehensive overhauls Re-blading Complete new rotor...

With the development of CHARM®, Open Grid Europe is providing an efficient leakage control method for natural gas pipeline networks and thus an alternative to the labour intensive practice of conducting on-site inspections of the pipelines with gas detection devices. CHARM® is a highly accurate infrared laser system integrated in a helicopter that is capable of precisely detecting even very low methane concentrations from the air. Even in the case of very complex pipeline topologies, the course of the pipeline can be detected consistently on a large scale during the flight by an automatic, highly precise scanning beam control system (autotracking), thus ensuring a reliable leak tightness inspection of the natural gas pipeline.

Maintenance and repair work on the natural gas network is generally carried out with the pipeline being gas-free, so the relevant pipe sections are isolated by installing valve assemblies and the gas in the isolated section is vented to atmosphere. By using our mobile compressors – individually or in highly efficient parallel operation – the network operator can transfer the gas from the isolated pipe section to another part of the system so it does not have to be vented to atmosphere. Connection points for the mobile compressors are available e.g. in the area of the main line valves or can generally be retrofitted. It makes economic sense to transfer the gas to another as this guarantees responsible handling of this primary energy source and makes a substantial contribution to protecting the environment. Services offered: Pipeline recompression until lowest residual pressure < 3bar Reduction of methane emissions by up to 95% Responsible handling with primary energy

Repair kit for pipelines with all accessories for mounting the sleeve and repairing the pipe. The sleeve fitting is manufactured of solid-woven reinforced fiberglass, made in a unique way, which gives a number of advantages compared to standard fittings: fire resistance, high pressure, corrosion resistance, from 30 years of operation. Scope of fitting application - pipelines, including non-metallic, underground, ground, aboveground and underwater versions, with a diameter of 50 to 1200 mm with a maximum internal working pressure of up to 20 Mpa (200 Bar) for pumping gas, oil, petroleum products and other gaseous and liquid media, operated at temperatures from minus 60°C to plus 180°C. Fittings are used for permanent (major) repairs of through and part-through flaws of pipelines with a maximum internal pressure of not more than 12 MPa. Fittings are used for sealing through flaws (fistulas), for integral repair of pipelines with a pressure of up to 20 MPa. Major repairs.
