    Spiral Drilling Collar

    ‌RockySea Petro Spiral Drill CollarIn directional drilling, due to the large deviated well and the large contact area between the drill collar and the borehole wall, problems like sticking and jamming are more likely to happen. The spiral drill collar reduces the contact area between the drill collar and the borehole wall, so it is widely used. Spiral drill collars are not listed in intl standards, but due to its practical value, many manufacturers have produced them.Description The function of

API C110 Steel Grade

Date:2024-05-15 Popularity:1174

API C110 Steel Grade for Sour Service Applications

The API C110 steel grade is a controlled yield strength grade specifically designed for use in deeper sour condensate wells where the risk of sulfide stress corrosion cracking (SSCC) is high. This steel grade is engineered to provide exceptional resistance to SSCC, making it a preferred choice for applications in the oil and gas industry where sour service conditions prevail.

Mechanical Properties

The mechanical properties of API C110 steel grade are tailored to ensure a balance of strength and ductility, suitable for the challenging conditions encountered in sour service environments:

  • Minimum Yield Strength: 110,000 psi
  • Maximum Yield Strength: 120,000 psi
  • Minimum Tensile Strength: 115,000 psi
  • Maximum Hardness: 30.0 HRC (mean), 32.0 HRC (individual)

SSCC Resistance

One of the critical features of API C110 steel is its resistance to SSCC, which is a significant concern in sour service applications. To ensure the material's reliability, each heat of API C110 steel undergoes SSCC testing to meet a threshold stress of 85% of the specified minimum yield strength.

Applications

API C110 steel is typically used in:

  • Sour condensate wells where the presence of hydrogen sulfide (H2S) creates a corrosive environment.
  • Downhole tubular goods that require high-strength and high-hardness properties to withstand the rigors of deep well drilling and production.
  • Components that are critical to the structural integrity of oil and gas wells, such as casing and tubing.

Standards and Testing

The API C110 steel grade adheres to the API 5CT standard, which specifies the requirements for casing and tubing. This standard ensures that the steel meets the necessary quality and performance criteria for safe and efficient use in petroleum operations.
