P110 is a high-grade seamless steel pipe for petroleum applications under the API 5CT standard, belonging to low-alloy high-strength steel. Its core advantages are:
High strength load-bearing capacity: Yield strength reaches 758-965MPa, tensile strength ≥862MPa, suitable for ultra-deep wells and high-pressure oil and gas reservoirs;
Corrosion resistance: Through optimized chemical composition (such as the ratio of chromium and molybdenum), it can resist the erosion of corrosive media such as H₂S;
Process compatibility: Supports cold drawing, hot rolling, and heat treatment processes to meet different engineering needs.
As a mainstream material for oilfield casing, P110 is widely used in shale gas extraction, coalbed methane development, and geothermal well construction.
Chemical composition analysis of P110 material under API 5CT standard
| Chemical composition | Content Range(%) |
|---|---|
| C | 0.26 - 0.35 |
| Si | 0.17 - 0.37 |
| Mn | 0.40 - 0.70 |
| Cr | 0.80 - 1.10 |
| Mo | 0.15 - 0.25 |
| P | ≤0.020 |
| S | ≤0.010 |
Carbon content directly affects the strength grade of P110; exceeding 0.35% may increase susceptibility to welding cracks.
The synergistic effect of chromium and molybdenum allows it to maintain stability in sulfur-containing environments.
Mechanical properties
| Performance Indicators | Standard Requirements |
|---|---|
| Tensile Strength (MPa) | ≥ 862 |
| Yield Strength (MPa) | 758 - 965 |
| Elongation (%) | ≥ 18 |
| Impact Test | Impact Energy ≥ 27J at -20℃ |
| Hardness | ≤ 241HB (Brinell Hardness) |
The yield strength range design takes into account both the high pressure requirements of deep wells and the feasibility of material processing;
The impact test temperature is set at -20℃, covering most cold-region oil and gas field conditions.
