Home > Seamless Pipe > Oil & Gas Pipeline
Inox Steel India is a trusted supplier of Oil & Gas pipeline materials, providing complete solutions for upstream, midstream, and downstream operations.
We supply both API 5L Line Pipes and ASTM A106 High-Temperature Carbon Steel Pipes, which together form the backbone of modern pipeline networks.
API 5L is used for long-distance transmission of oil, natural gas, and hydrocarbons, while A106 is used for high-temperature refinery & process lines.
Both materials are essential in refineries, petrochemical plants, gas processing units, offshore platforms, compressor stations, and crude oil transportation networks.
Our pipes are manufactured using seamless, ERW, LSAW, and HSAW processes depending on project requirement, and supplied with coating, NDT, hydro test, and full API/ASME documentation.
Oil & Gas pipelines operate under:
Thus the materials must deliver:
Why API 5L + A106 Are Always Used Together:
| Pipe Type | Use Case | Why It’s Used |
|---|---|---|
| API 5L (PSL1/PSL2) | Long-distance oil & gas pipelines | High yield strength, coating compatibility, sour service |
| ASTM A106 | Process piping inside refinery & gas plants | Withstands high temperature & pressure |
Together they complete pipe routing from wellhead → refinery → distribution network.
