Casing Pipe Fundamentals
Engineered as heavy-duty conduits, casing pipes serve dual critical functions in well construction: structural reinforcement and environmental protection. Manufactured from high-grade steel, these tubes are:
• Cement-bonded into drilled formations to stabilize wellbore integrity
• Designed to prevent wall collapse and groundwater contamination
• Customizable in diameter (4"-36"+) and wall thickness (schedule 40-XXH) for site-specific demands
Austenitic Grades
304/304L • 316/316L • 309S • 310S • 317L • 321H
347H • 904L • 254SMO
Material Advantages
SS pipes excel in applications demanding:
◼ Extreme temperature resilience (-200°C to 1150°C)
◼ Pitting/crevice corrosion resistance (PREN 19-45)
◼ Hygienic surface finish (Ra ≤ 0.8μm achievable)
◼ Aesthetic permanence (non-oxidizing surfaces)
Performance Benchmarking
Compared to carbon steel counterparts, stainless systems demonstrate:
✓ 300% improvement in cyclic corrosion testing (ASTM G85)
✓ 40% higher yield strength at cryogenic temps
✓ Superior work hardening capacity (n-value 0.4-0.6)
✓ Enhanced ductility (60-70% elongation typical)
