IMR Hamburg Installation of LP, IP and HP Piping

IMR Hamburg specialises in pipeline construction for power stations and industrial facilities worldwide. We offer services on a long-term basis, starting with planning and the supply of materials and with rational as well as economical production included.

Our performance spectrum includes consultation, planning, piping and spool construction, calculation, delivery and assembly, commissioning and documentation, as well as revisions including quality assurance and project management.

HP, IP and LP piping systems

We have become particularly well-known in the high-pressure field, processing all kinds of materials from high-alloyed ‘P92’ 1.4901 to plastics. The planning of IP and LP piping are CAD / CAE backed with ISOGEN based software solutions from Intergraph PP&M Smart Plant and SIGMA Rohr2 stress analysis according to ASME B31.1, B31.3, B31.4, B31.5, B31,8, Cl.1 Cl.2, Cl.3, EN13480, Stoomwezen D1101, KTA 3201.2, KTA 3211.2, FDBR, AGFW FW401, ISO14692, British Standard 7159, KRV, Wavistrong GFK.

We can process pipelines in all shapes and sizes. Pipe cutting, bevelling and assembling are always supervised from internal quality management. Documentation and pressure testing is implemented. We supply project detail engineering and material management for LP, IP and HP piping, fittings, flanges, bar and valves.

We have WPQR and comprehensive experience for the typical power plant, boiler and pressure vessel, process, pharma, shipping and offshore industry piping material range:
