Project Overview
Work order for heavy earthwork excavation, laying of massive 3000 mm (3.0 metre) diameter Mild Steel (MS) pipelines, specialized jointing/welding, hydrostatic pressure testing, and precision trench refilling executed as a crucial conduit of the Rajiv Dummagudem Lift Irrigation Scheme.
Executing pipeline works of 3000 mm diameter requires specialized heavy-lift rigging, laser-guided grade alignment, and stringent ultrasonic weld inspection to withstand massive hydrostatic conveyance heads delivering vital irrigation waters.
Key Deliverables & Scope
- Deep earthwork trench excavation across challenging geotechnical strata
- Precision crane rigging and lowering of 3000 mm dia MS pipes
- Full-penetration circumferential butt welding and non-destructive joint inspection
- Internal mortar lining / external anti-corrosive coating protection
- Controlled layer-by-layer compacted trench backfilling and restoration
