Sour Gas Corrosion Testing in India

In sour service environments where hydrogen sulfide (H₂S) poses a serious threat to material integrity, having the right testing partner is critical. TCR Engineering’s advanced corrosion laboratory in Mumbai is fully equipped to perform specialized sour gas corrosion testing, helping global clients ensure materials meet the toughest oilfield conditions.

Our Mumbai based corrosion lab is approved by PDO Oman and Qatar Energy, and proudly serves a portfolio of leading international energy companies. We have worked extensively with Shell and ONGC as well for their corrosion testing.

Comprehensive Sour Gas Corrosion Testing Capabilities

TCR offers advanced testing solutions in accordance with all major international sour service standards, including:

• NACE MR0175 / ISO 15156-2 – Materials qualification for use in H₂S-containing oilfield environments.

• NACE TM0177 – Sulfide Stress Cracking (SSC) test methods using tensile and four-point bend samples.

• NACE TM0284 – Hydrogen-Induced Cracking (HIC) testing for carbon and low-alloy steels.

• NACE TM0316 – Testing of corrosion-resistant alloys (CRAs) under high-pressure sour gas conditions.

• ASTM G39 – Four-point bend stress corrosion cracking evaluation.

• EFC-16:2009 – Guidelines for lab testing of materials exposed to sour service.

• ISO 7539-2 – Preparation and use of bent-beam specimens for stress corrosion testing.

Specialized Testing Services at TCR Mumbai

• SSC Testing (NACE TM0177, Method A) – Conducted using tensile specimens at ambient and elevated temperatures.

• Four-Point Bend Testing (NACE TM0177 / ASTM G39 / ISO 7539-2) – To evaluate susceptibility to cracking under applied or residual stress.

• HIC Testing (NACE TM0284) – To detect hydrogen-induced damage in steels such as blistering and stepwise cracking.

• CRA Testing (NACE TM0316) – Qualification of corrosion-resistant alloys for sour environments at high temperature and pressure.

Each test is performed under strictly controlled lab conditions using precision-engineered equipment, with expert metallurgists ensuring data integrity and technical accuracy.

Our HIC and SSC testing facility is equipped with:

• Dedicated test chambers designed to meet international testing standards (e.g., NACE TM0284 for HIC and NACE TM0177 for SSC).

• Automatic temperature and pressure control systems to ensure accurate simulation of downhole and refinery conditions.

• Real-time monitoring systems and high-precision instrumentation for critical parameters such as pH, H₂S concentration.

• Specialized sample preparation and post-test evaluation areas, including metallography and microscopy for crack detection and evaluation.

• Experienced metallurgists and technical staff who ensure strict adherence to QA/QC protocols throughout the testing lifecycle.

We take great pride in our robust testing infrastructure, which supports our commitment to delivering accurate, reliable, and standards-compliant test results for our clients across different industries.
