22@ urban networks in Poble Nou district

Installation of a network of pre-insulated hot and cold water pipes for the heating and air conditioning of buildings and facilities in the 22@ area of the Barcelona’s Poble Nou district.

From 2005 to date
Type of service:
Cold-hot distribution networks

Work includes: redefinition of networks, expansion studies, technical purchasing of piping, values and instrumentation, digging of trenches, laying and welding of pipes, coating of joints between pipes, chemical cleaning, electrical continuity tests and hydraulic tests and refilling of trenches and replacements.
