Magnetic Flux Leakage (MFL) is a nondestructive examination technique that uses electromagnetism to inspect for flaws or material degradation in steel structures. In the oil and gas industry, it is often used to search for flaws in piping and pipelines, as well as aboveground storage tank floors. MFL uses magnets to temporarily magnetize the structure. If there are flaws present, the magnetic field created will show distortions, signaling the presence of things like corrosion, pitting, and wall loss.

Refinery, petrochemical, and storage tank operators are responsible for properly cleaning facility tanks on a periodic maintenance basis, typically in 20 to 30 year increments. This article provides a suggested “checklist” of inspection activities to ensure safe and reliable operations after cleaning.

Nondestructive Testing (NDT) makes up the majority of testing performed in our industry. There many different types of nondestructive testing techniques. Each method has its own advantages and disadvantages; each can detect different types of flaws. Some are simple to perform, others are difficult. Some are used on several different types of equipment, others are more restricted.

We talk about heat exchangers quite a bit here on Inspectioneering, most recently in the January/February issue of the Journal. This is because heat exchangers are vital pieces of equipment in nearly every type of plant or facility.
Facilities are facing increasing challenges, including justifying inflated budgets, managing contractor hours, ensuring regulatory compliance and qualifying the work being completed. To help facilities manage evolving inspection requirements, PinnacleART offers Fixed-Price Inspection (FPI), meaning we will develop and execute a comprehensive Risk-Based Inspection plan for one fixed-price. Yes, you read that right – one fixed-price.

The development of advanced NDE techniques/tools is one of the reasons the inspection trade has taken significant steps forward in the last couple decades; and the advancements appear to be accelerating. One of the many ways to keep up with advancing NDE technology is to attend the semi-annual NDE task group meetings at the Spring and Fall API Refining and Equipment Standards Meetings. In fact, that T/G is planning to document many of the advanced NDE...

The pigging industry has developed a tremendous range of techniques and technologies, and it is probably fair to say that there are few pipelines in the world that cannot be cleaned and inspected, although the success of such operations will often depend on the available budget.
