مدة التوريد4 - 8 weeks mill indent
The baseline transmission grade. X52 balances weldability against pressure rating, which is why it remains the default for gathering lines, utility piping and plant interconnects where wall thickness rather than yield strength drives the design.
- PSL2 supply with controlled chemistry and impact testing
- Sour service variants to NACE MR0175 / ISO 15156 on request
- Bevelled ends, 3LPE / 3LPP coating and hydrotest reports arranged
- Third-party inspection and EN 10204 3.2 certification available

API 5L X65 / L450
Mill indentAPI 5L X65ISO 3183 L450
The workhorse offshore and high-pressure grade. The higher yield allows a thinner wall at the same design pressure, cutting pipe weight on risers and long tie-backs, and X65 is the grade most often specified with sour service and HIC testing.

API 5L X70 / L485
Mill indentAPI 5L X70ISO 3183 L485
High strength thermomechanically rolled line pipe for long distance, large diameter transmission. X70 is specified where the pipeline economics are driven by wall thickness and steel tonnage over hundreds of kilometres.
