PROJECT PIPING SOLUTIONS OVERVIEW

High-integrity process and transmission piping packages designed to fulfill the ultra-stringent technical requirements of offshore extraction, refining, and global energy transport.
- SUPPLY SCOPE
Severe-Service Seamless Steel Pipes
- Engineered specifically for high-pressure loops and extreme temperature headers.
- The seamless manufacturing process eliminates longitudinal weld zones, ensuring uniform isotropic mechanical properties and structural resilience.
High-Performance Welded Steel Pipes
- Longitudinal Submerged Arc Welded (LSAW): The premier solution for high-load structural sections and high-pressure mainline transmission systems.
- Spiral Submerged Arc Welded (SSAW/HSAW): Cost-effective, large-diameter piping engineered for long-distance water, gas, and liquid hydrocarbon mainlines.
- Electric Resistance Welded (ERW): Sourced for lower-pressure utility loops, refinery balance-of-plant systems, and small-bore process lines.
Advanced Anti-Corrosion Linings & External Coatings
- External Protective Coatings: Multi-layer anti-corrosion barrier coatings including 3LPE, 3LPP, and Fusion Bonded Epoxy (FBE) to isolate the pipe from soil and marine oxidation.
- Internal Alloy Cladding & Lining: Cost-optimized metallurgical solutions featuring internal CRA weld overlays or mechanical linings to shield the carbon steel host pipe from corrosive, sour fluid flows.

- PROJECT SUPPLY CAPABILITIES & LOGISTICS
Holistic Bulk Material Management
- TATIS possesses the supply chain infrastructure to source, consolidate, and optimize massive bulk piping bills of materials (MTO).
- We ensure consistency across manufacturing tolerances, heat treatment conditions, and quality documentation packages, eliminating scheduling conflicts for EPC contractors.
Quality Controls & Verification Testing
- Every pipe length is backed by EN 10204 3.1 or 3.2 material certificates.
- Inspection includes Non-Destructive Testing (hydrotesting, ultrasonic testing, radiographic testing), mechanical testing (tensile, flattening, bend tests), and chemical analysis.
- All verification is witnessed by independent third-party inspection agencies such as Bureau Veritas, DNV, and Lloyd’s Register.
Strategic AVL Sourcing
- Piping materials are sourced exclusively from globally approved steel manufacturers recognized by major oil & gas operators in Europe, South Korea, and Japan.
Specialist Machine Shop Services
- High-precision end beveling to match welding procedures, cut-to-length services, and export-grade seaworthy packaging to prevent transit damage and corrosion.
