Line routes are determined with GPS-based coordination and topographic analyses. Route, flow direction and ring configuration are optimized according to field conditions
Fire hydrant intervals are generally planned between 50–90 meters according to international standards
Each ring line is designed to work integrated with the main pump station and backup storage connections
HDPE pipes used in line laying are joined with butt welding according to DVS 2207-1 standards
After welding, all joint points are checked with pressure test, tightness control and NDT
The final step before commissioning the system is hydrostatic test and flow-pressure measurement
Depending on ground conditions, lines are surrounded with protective fill materials, and valve chambers are built at connection points. In this way, the external line works safely for many years against possible pressure changes, earthquake effects and thermal expansions
HDPE (PE100) - for underground ring lines
Galvanized / Stainless Steel - for internal installations
Cast Iron Valves and Connection Elements - for high pressure points
