The DuPont™ StreaMax™ XF Coating Systems for Oil and Gas Well Tubulars feature the following:
- Multi-layered system, with each layer having a specific engineered function
- Holiday-free surface throughout the pipe
- Uniform adhesion to metal substrate
- Excellent non-stick and product release properties
- Extremely wide operating temperature range (from -100°C to 260°C to –150°F to 500°F continuous operating temperature)
- Resistant to high pressures (up to 10,000 psi) and rapid decompression
- Excellent chemical resistance from H2S and CO2 gases and all acids and bases, even at high temperature
- Very low friction coefficient
Demonstrated Results with DuPont™ StreaMax™ XF Coating
| Autoclave lab test results |
Unaffected after 29 days of exposure at 1026 psi and 122°C (251°F) gas phase (5% H2S, 5% CO2, 90% methane), organic phase (kerosene, toluene), and brine phase |
| Paraffin cold finger tests |
60% less buildup vs. bare steel and other coatings |
| Paraffin flow loop tests |
60% less deposition with DuPont™ StreaMax™ XF coatings vs. bare steel at turbulent flow |
| Asphaltene flow loop tests |
66% reduction in asphaltene deposits with DuPont™ StreaMax™ XF coatings vs. bare steel |
| Scale tests |
Over 50% deposit reduction with DuPont™ StreaMax™ XF coatings vs. bare steel |
| Live well tests |
In a Western Canada well having a long history of asphaltene problems, using coupons suspended at the reservoir bottom for 21 days, no deposits were found on tubulars lined with DuPont™ StreaMax™ XF coatings. |
| High-pressure flow loop tests |
Tests using entrained sand have confirmed abrasion resistance properties. |
