Overview
The A106 Gr B NACE PIPE is engineered for use in sour service conditions, where exposure to hydrogen sulfide (H₂S) or other corrosive elements is present. Womic Steel manufactures NACE PIPES that are designed to provide exceptional resistance to sulfide stress cracking (SSC) and hydrogen-induced cracking (HIC) under high-pressure, high-temperature environments. These pipes meet NACE and MR 0175 standards, ensuring they are suited for critical applications in industries like oil & gas, chemical processing, petrochemical, and power generation.

Mechanical Properties
The A106 Gr B NACE PIPE is built for high performance in extreme conditions, providing both tensile strength and elongation under pressure and temperature.
|
Property |
Value |
| Yield Strength (σ₀.₂) | 205 MPa |
| Tensile Strength (σb) | 415-550 MPa |
| Elongation (El) | ≥ 20% |
| Hardness | ≤ 85 HRB |
| Impact Toughness | ≥ 20 J at -20°C |
These mechanical properties ensure that the NACE PIPE is able to resist cracking and stress under harsh conditions such as high-pressure, high-temperature, and sour environments.
Corrosion Resistance (HIC & SSC Testing)
The A106 Gr B NACE PIPE is designed to withstand sour service conditions, and is rigorously tested for Hydrogen Induced Cracking (HIC) and Sulfide Stress Cracking (SSC) in compliance with MR 0175 standards. These tests are critical for evaluating the pipe's ability to perform in environments where hydrogen sulfide or other acidic compounds are present.
HIC (Hydrogen Induced Cracking) Testing
This test evaluates the pipe’s resistance to hydrogen-induced cracks that occur when exposed to sour environments, such as those containing hydrogen sulfide (H₂S).
SSC (Sulfide Stress Cracking) Testing
This test assesses the pipe’s ability to resist cracking under stress when exposed to hydrogen sulfide. It simulates conditions found in sour service environments like oil and gas fields.
Both of these tests ensure that the A106 Gr B NACE PIPE meets the stringent demands of industries working in sour environments, and the steel is resistant to cracking and other forms of corrosion.
Physical Properties
The A106 Gr B NACE PIPE has the following physical properties that ensure it performs reliably under extreme temperatures and pressures:
|
Property |
Value |
| Density | 7.85 g/cm³ |
| Thermal Conductivity | 45.5 W/m·K |
| Elastic Modulus | 200 GPa |
| Coefficient of Thermal Expansion | 11.5 x 10⁻⁶ /°C |
| Electrical Resistivity | 0.00000103 Ω·m |
These properties allow the pipe to maintain structural integrity even in extreme conditions and temperature variations.
