OVERVIEW
High-reliability spare parts and pipeline sealing components designed to minimize unscheduled plant downtime and safeguard long-term system structural integrity.
- PRODUCT TIMELINES
High-Pressure Sealing Gaskets
- Spiral Wound Gaskets (SWG): Engineered with alternating layers of metallic winding strips and non-metallic fillers, integrated with solid outer and inner retaining rings to prevent gasket blowout under intense thermal pressure cycling.
- Ring Type Joint Gaskets (RTJ): Heavy-duty solid metal gaskets machined to tight tolerances for installation within high-pressure flange grooves, utilizing plastic metal deformation to establish robust joints.
Heavy-Duty Fasteners & Stud Bolts
- Continuous-thread stud bolts and heavy hex nuts engineered to optimize long-term joint tension and resist thread relaxation.
Monolithic Isolation Joints (MIJ)
- Factory-assembled, boltless monolithic isolation joints designed to replace high-maintenance insulation gasket kits. Tightly isolates pipeline segments to maintain cathodic protection currents, mitigate stray currents, and eliminate galvanic corrosion across buried mainlines and subsea tie-ins.
Pipeline Maintenance & Filtration Equipment
- Pipeline Scraper Traps: Complete pigging launcher and receiver vessels configured for chemical scraping and automated pipeline cleaning lines.
- Process Fluid Strainers: High-capacity Y-strainers and T-strainers featuring robust stainless steel mesh elements to intercept solid particulate and protect downstream rotating machinery.

- LOGISTICAL EXPEDITING & TURNAROUND SERVICES
- Fast-Track Turnaround Expediting: To optimize critical maintenance windows during scheduled refinery shutdowns, TATIS utilizes its regional stocking network to fulfill emergency material demands, reducing lead times and mitigating downtime losses.
- Flange Joint Combo Kits: We supply integrated Flange Joint Kits comprising a matching flange pair, custom-vetted gaskets, and the correct quantity of calibrated stud bolts. This eliminates loose material matching sorting, allowing maintenance crews to execute field replacements immediately.
- Fluoropolymer Anti-Galling Coatings: Stud bolts are available coated with specialized high-grade Xylan or PTFE layers. This finish isolates the steel from saltwater atmospheric rusting and prevents thread galling, ensuring low breakout torques during subsequent turnarounds.
- 100% Verified Quality Records: Even for small accessories like sealing components and fasteners, TATIS maintains 100% traceability, delivering complete EN 10204 3.1 material test certificates to ensure compliance for final quality dossier handovers.
