A core strength of Cimpina is the ability to fabricate Class 1[1] pipework to British, European and American Standards. For pipelines used in the transfer of solids, liquids, or gases – Cimpina has the complete range of skills and certifications. Operationally the pipework division straddles many market sectors, from Aerospace to Petrochemical. The Oil and Gas market is particularly important as the level of skill and traceability required mirrors our own company ethos.

Our Engineers and Welders are extensively trained and specifically hold Gas Safe Certification and welding certification to ASME IX and EN9606 in TIG, MIG/MAG, Flux Cored, and MMA processes. The range of pipe capabilities extends from small bore up to 1500mm diameter water mains.

[1] Generally pipework operating at ≥17 Bar pressure or operating at ≥200 Deg Celsius(liquids)/ ≥200 Deg Celsius(Gas or Steam)

A complete service covering project management, design, fabrication, installation, commissioning and maintenance is provided. The nature of pipework requires the ability to perform well in both planned and reactive/emergency works. We meet this need (a) with our willing and flexible staff and (b) with our extensive pipe workshop facilities which include equipment for welding, threading, bending, lifting and pressure testing. This is further complimented by an extensive range of fittings, gaskets, and pipes.

Pipework rates are either based on term contracts, unit schedules or complete project cost.

On multi-disciplined projects we have a collaborative network of carefully selected contractors who provide services outside of Cimpina’s expertise i.e. civil, electrical, instrumentation and HVAC.

With all projects a full traceability and quality assurance pack is issued to client, which includes quality plan; work instructions, pipeline weld maps, welding procedure specifications, welders qualifications, material inspection certificates, performance and test certificates.
