A ranked overview of our most requested and reliable OCTG, connecting components, and custom fabrication services.
1. Oil Country Tubular Goods (OCTG) – API 5CT Casing
Top Grades & Specifications:
- API 5CT J55/K55: The industry standard for surface and intermediate casing. Renowned for excellent weldability and cost-effectiveness for less corrosive environments.
- Key Features: Seamless manufacturing, precise threading (BTC, LTC, STC), strict adherence to API 5CT dimensional and mechanical property standards.
- Primary Applications: Onshore and offshore oil & gas wells, water wells, geothermal wells.
- Why It Tops Our List: Consistent quality, immediate availability in various sizes (OD, wall thickness), and full certification make this our most trusted and best-selling product.
2. High-Performance OCTG – API 5CRA (Corrosion Resistant Alloy)
Top Grades & Specifications:
- API 5CRA Compliant Alloys (e.g., 13Cr, Super 13Cr, Duplex, Super Duplex): Engineered for severe service involving high concentrations of CO₂, H₂S, and chlorides.
- Key Features: Superior corrosion and pitting resistance, high strength-to-weight ratio, enhanced performance in high-pressure/high-temperature (HPHT) wells.
- Primary Applications: Sour gas fields, deepwater offshore projects, carbon capture (CCS) injection wells, geothermal projects with aggressive fluids.
- Why It’s a Top Product: Delivers unparalleled longevity and safety in the most challenging well conditions, reducing lifetime operational costs and failure risks.
3. Industrial Pipe Flanges
Top Types & Standards:
- Weld Neck (WN), Slip-On (SO), Blind (BL), Socket Weld (SW): Comprehensive range for every system need.
- Standards: ASME/ANSI B16.5, B16.47, API 6A, EN 1092-1. Materials include ASTM A105, A350 LF2, A182 F316/304, and duplex alloys.
- Pressure Ratings: Class 150 to 2500, and API series.
- Primary Applications: Connecting pipes, valves, pumps, and equipment in process plants, refineries, pipelines, and offshore platforms.
- Why It’s a Top Product: Essential for any piping system. We provide full traceability, precise machining, and complete sets (flange, gasket, bolts/nuts) for leak-proof integrity.
4. Pipe Spool Fabrication
Top Services & Capabilities:
- Custom Fabrication: Pre-fabricated pipe sections with welded fittings, flanges, and supports according to isometric drawings
