Product description
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)

FAQ
Q:What is the purpose of steel pipes?
A:Steel pipes protect carrier pipelines from external loads,
corrosion, and physical damage, ensuring their safety and
functionality. |
Q:What materials are used for steel pipes?
A:Common materials include 304,304L,316,316L,310S,duplex stainless
steel,etc. Depending on the application and environmental
conditions. |
Q:How are steel pipes installed?
A:Steel pipes can be installed using methods such as open cut,
horizontal directional drilling (HDD), or jack and bore. |
Q: How is the wall thickness of a steel pipe determined?
A:The wall thickness is calculated based on external pressure, pipe
diameter, allowable stress, and safety factors, using formulas from
industry standards. |
