Flexural Strength Testing

Flexural strength testing, also known as the modulus of rupture test or the bending test, is a standard method used to determine the strength and performance of concrete in bending or flexural conditions. It is an important test to evaluate the suitability of concrete...

Weldability of Structural Steels

If weld preparation is excellent and operator-induced defects (e.g., lack of penetration or fusion) are avoided, all the standard structural steels can be successfully welded. However, several steels may require special treatments to achieve a satisfactory...

Prevent Corrosion: Strategies for Dissimilar Metal and Galvanic Corrosion

Corrosion is an enemy to numerous industries like oil and gas, leading to massive financial losses, environmental degradation, and potential safety hazards. One common type of corrosion that warrants particular attention is galvanic or dissimilar metal corrosion. This...

Hydrogen Embrittlement

Hydrogen Embrittlement Hydrogen embrittlement can occur when metals are exposed to hydrogen gas or certain hydrogen-containing compounds. When hydrogen atoms diffuse into metal, they can weaken the metal's atomic bonds and cause it to become more brittle and prone to...

What are failure mechanisms for metals?

There are several failure mechanisms for metals, including: Fatigue Failure: This is the most common failure mechanism for metals. It occurs when a material is subjected to repeated loading and unloading cycles. Over time, cracks...

What is the reliability testing of steel?

Reliability testing of steel is a set of tests and analyses performed to determine the ability of steel to resist failure under specific conditions over some time. These tests ensure that the steel used in structures, machinery, and other applications is dependable...

Hydrogen-Induced Cracking

Hydrogen-induced cracking (HIC) is a form of material degradation and stress corrosion cracking. This can occur in metals and alloys in the presence of hydrogen. The diffusion of atomic hydrogen typically causes HIC into the metal or alloy. It can react with various...

Wet H2S Damage in Oil and Gas Systems

Hydrogen sulfide (H2S) is a highly toxic and corrosive gas that poses significant challenges to the oil and gas industry. When in the presence of moisture, H2S can cause severe damage to equipment and infrastructure, leading to:  Safety hazardsProduction...

Asphalt Inspection

Asphalt inspection involves:  Assessing its conditionIdentifying any damages or issuesDetermining the necessary repairs or maintenance Asphalt Inspection Process Visual Inspection:  Start by visually examining the asphalt surface. Look for signs of cracking,...

API 580

Risk Assessment API 580 is a standard published by the American Petroleum Institute (API) that provides guidelines for risk management in the petroleum industry. It outlines an API 580 risk-based inspection (RBI) methodology for determining the risk-based inspection...

Porosity in Welding

Porosity in welding refers to the presence of voids or gas pockets within a joint. It is a welding defect that can weaken the integrity and strength of the weld. Porosity appears as small holes or cavities within the metal or at the interface between the weld and the...

Metal Properties: Strength and Toughness

Metal properties such as yield strength and toughness are related properties. They refer to different aspects of a material’s behavior under load. Yield strength refers to a metal’s ability to resist deformation and failure under an applied load. Toughness refers to a...

What is API 580 Risk-Based Inspection (RBI)?

API 580 is a certification program developed by the American Petroleum Institute (API) that focuses on Risk-Based Inspection (RBI) for equipment used in the oil and gas industry. RBI is a methodology used to evaluate equipment failure's likelihood and consequences and...
