GB/T 19830 H40 J55 K55 N80 N80 Seamless Steel Tube Steel Pipes Casing For Petroleum And Natural Gas

Material

The GB/T 19830 standard specifies the requirements for seamless steel tubes used as casing in petroleum and natural gas industries. The materials used for these pipes are designed to withstand high pressures and corrosive environments typically found in oil and gas extraction.

Specification

The specifications for the seamless steel tubes under the GB/T 19830 standard include various grades such as H40, J55, K55, N80, and N80Q. Each grade has specific requirements regarding dimensions, tolerances, and mechanical properties.

Specification Overview

Grade Outer Diameter (mm) Wall Thickness (mm) Length (m)
H40 114.3 - 508.0 5.0 - 20.0 6 - 12
J55 114.3 - 508.0 5.0 - 20.0 6 - 12
K55 114.3 - 508.0 5.0 - 20.0 6 - 12
N80 114.3 - 508.0 5.0 - 20.0 6 - 12
N80Q 114.3 - 508.0 5.0 - 20.0 6 - 12

Chemical Composition

The chemical composition of the steel grades is crucial for ensuring the pipes can withstand the harsh conditions of oil and gas extraction. Below is a summary of the typical chemical composition for each grade.

Chemical Composition

Grade C (%) Si (%) Mn (%) P (%) S (%) Cr (%) Ni (%) Mo (%)
H40 ≤0.26 ≤0.55 0.40-0.90 ≤0.030 ≤0.030 ≤0.15 ≤0.15 -
J55 ≤0.26 ≤0.55 0.40-0.90 ≤0.030 ≤0.030 ≤0.15 ≤0.15 -
K55 ≤0.26 ≤0.55 0.40-0.90 ≤0.030 ≤0.030 ≤0.15 ≤0.15 -
N80 ≤0.30 ≤0.55 0.40-0.90 ≤0.030 ≤0.030 ≤0.15 ≤0.15 -
N80Q ≤0.30 ≤0.55 0.40-0.90 ≤0.030 ≤0.030 ≤0.15 ≤0.15 -

Mechanical Properties

The mechanical properties of the seamless steel tubes are essential for ensuring their performance under operational conditions. The following table summarizes the key mechanical properties for each grade.

Mechanical Properties

Grade Yield Strength (MPa) Tensile Strength (MPa) Elongation (%)
H40 ≥ 241 414 - 552 ≥ 20
J55 ≥ 379 517 - 655 ≥ 20
K55 ≥ 379 517 - 655 ≥ 20
N80 ≥ 517 620 - 758 ≥ 18
N80Q ≥ 517 620 - 758 ≥ 18

Application

The seamless steel tubes specified in GB/T 19830 are primarily used in the oil and gas industry for casing applications. These pipes are essential for:

  • Well Construction: Providing structural integrity to oil and gas wells.
  • Pressure Containment: Withstanding high pressures encountered during extraction.
  • Corrosion Resistance: Protecting against corrosive environments found in subsurface conditions.
