Gas & Oil Pipes Industry
High-performance pipe and tube solutions for upstream drilling, offshore platforms, refineries, and downstream processing — built to withstand extreme pressure, heat, and aggressive media.
High-Performance Pipes for Oil & Gas Applications
Metinox Overseas has been providing high performance pipe and tube solutions to meet the needs of the oil & gas industry for several years. Our pipes deliver corrosion resistance, pressure integrity and metallurgical integrity that these critical energy applications require from upstream drilling and offshore platforms, through refineries, and downstream processing. All of our products are manufactured and tested to international standards, and provide both operators and EPC contractors with the confidence in performance over time under heat, pressure and aggressive media.
Our stainless steel pipe and tube product range includes both seamless and welded pipe using SS 304 and SS 904L grades; our high-temperature service coated alloy steel pipe products include P11. We supply a complete range of specialty alloy pipes such as Inconel 625, Inconel 600, Incoloy 825, Monel 400, Alloy 20, 254 SMO and duplex and super duplex steel for extreme corrosive sour service applications. We also have available carbon steel pipes and copper pipes and tubes for general process, structural and utility applications.
Key Applications & Grade Rationale
| Application | Service Conditions | Recommended Grade | Why This Grade |
|---|---|---|---|
| Upstream Drilling & Wellheads | HPHT H₂S Sour Service | Inconel 625 Super Duplex S32750 | Outstanding resistance to chloride SCC and H₂S at elevated temperatures |
| Offshore Platforms & Topsides | Seawater Corrosion High Pressure | Duplex S31803 / S32205 SS 904L | High PREN (>34) provides superior resistance to pitting and crevice corrosion |
| Subsea Flowlines & Risers | Deep Sea CO₂ / H₂S | Super Duplex S32750 / S32760 Inconel 825 | Exceptional strength-to-weight ratio and corrosion resistance in deepwater environments |
| Onshore & Cross-Country Pipelines | Sweet Service High Flow | API 5L X52 / X65 A106 Gr.B | Cost-effective; high yield strength for long-distance transmission at elevated pressure |
| Refineries & Gas Processing Units | High Temperature Oxidising Media | Alloy Steel P11 / P22 / P91 SS 304 | Chromium-molybdenum alloys retain creep strength and oxidation resistance up to 650 °C |
| Seawater Injection Systems | Chloride Rich High Velocity | Super Duplex S32750 254 SMO | PREN >40 prevents localised corrosion under aggressive seawater at pump pressures |
