The Company
KaGaWa Rohrleitungs- und Anlagenbau GmbH was founded in Berlin in 2006 and specialises in the planning and execution of pipelines of all kinds – in plant construction as well as in buried pipeline construction, in all dimensions and pressure classes. The service portfolio includes pipeline construction, plant construction, station construction and energy supply with a focus on district heating and cooling. Materials processed include fine-grain structural steels, stainless steels and piping materials made of polyethylene and polypropylene; the joining technology encompasses welding processes and conventional methods. KaGaWa works primarily for heat suppliers and takes on planning, fabrication and installation up to the handover of media at the transfer point. As a recognised training company of the Berlin Chamber of Crafts, the company trains plant mechanics with a focus on welding technology as well as HVAC and plumbing. The company is certified to ISO 9001 and FW 601 (welding certification) and is based in Berlin-Marzahn.
