Service · Oil & Gas Pipelines
Oil & Gas Pipeline Project
Cross-country and in-plant oil & gas pipeline construction — mainline welding, lowering, tie-ins, hot tapping and station piping. Our teams have executed live-line hot tapping and CGD mother station works where the line could not stop for the job.
Scope of Work
What this service covers.
Mainline Construction
Stringing, welding, coating repair, lowering and backfill of cross-country pipeline sections.
Hot Tapping
Live-line hot tap connections — fittings, split tees and tapping executed on operating pipelines without shutdown.
CGD & Station Piping
City gas distribution mother stations, terminals and station piping — fabrication, erection and commissioning support.
Tie-ins & Crossings
Section tie-ins, road and utility crossings, and golden-joint welding with 100% NDT.
Testing & Pre-commissioning
Cleaning, gauging, hydro testing, dewatering and drying ahead of commissioning.
Rehabilitation Works
Repair, recoating and modification works on existing pipeline assets.
Execution Method
How we deliver it.
Route & Constructability Review
ROW condition, access, crossings and permit requirements reviewed against the execution plan.
Welding & Laying
Qualified mainline crews with joint-wise NDT; coating integrity verified before lowering.
Tie-ins & Hot Taps
Planned isolation or live-line hot tapping with certified fittings and controlled procedures.
Test, Dry & Hand Over
Hydro test, dewatering, drying and documentation for commissioning teams.
Capability Snapshot
Materials, standards & testing.
HSE & quality, built in.
Every job runs under our HSE policy — hazard identification, EHS-trained crews, permits and stage-wise quality checks with full documentation.
Frequently Asked
Common questions.
Yes — hot tapping is one of our executed capabilities, including the Dokwa hot tapping works. Connections are made on operating lines using certified fittings and controlled tapping procedures, so throughput never stops.
Yes. We have executed CGD mother station works and station piping, and support city gas operators on tie-ins, extensions and station modifications.
