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...

ASTM E23 Charpy Testing

ASTM E23 is a standard developed by the American Society for Testing and Materials (ASTM) International. It outlines the procedures for performing standardized tests on materials and components to determine their mechanical properties. The standard explicitly covers...

Basic Understanding of Corrosion and Pipeline Inspection

Basic Diagram of Corrosion Process on Steel Corrosion of steel is a process by which the metal deteriorates and deteriorates over time due to exposure to various environmental factors such as moisture, chemicals, and oxygen. It is a common problem for many steel...

History Of Welding Aluminum

The GTAW process is quite often a viable option for welding aluminum.  It was developed in 1944 and is still used to weld aluminum alloys today.  Some of the highest quality welds used in critical applications, such as full penetration pipe welds on cryogenic pressure...

Causes Of Defects In Concrete Structures

Causes Of Defects In Concrete Structures

Concrete is known to be a very versatile and reliable material. Construction errors and negligence can lead to defects in a concrete structure. These defects in concrete structures can be due to:  Poor construction practicesPoor quality controlPoor structural design...

Post Weld Heat Treatment

Things Welding Inspectors Should Know When welding base materials, preheating and/or post-weld heat treatment may be necessary. These thermal treatments are generally required to ensure suitable weld integrity. They will typically prevent or remove undesirable...

Upfront Welding Inspection Considerations

Welding inspection involves much more than checking the accuracy of welds. Inspectors must know codes, standards, materials, and other fabrication processes. Welding inspection is not something to take lightly. Lives can depend on the accuracy of the inspection....

A Welding Inspector’s Tools of the Trade

Weld inspectors, especially those new to the trade, put a lot of emphasis on the equipment needed to do the job. Flashlight Mirror High-low gauge Pit gauge Bridge camera Borescope  However, this isn’t the entire toolkit. A welding inspector must also know the...
