Everything to know about Storage tank Inspection Services

Posted on

Big storage tanks like above-ground storage tanks, underground storage tanks or pressure vessels are a crucial component for various industries. Commercial storage tanks are designed for storing a variety of products like chemicals, fuels, vapours, gases, and whatnot. If storage tanks are not checked and maintained properly, it could lead to catastrophic results like leakage, contamination, explosion, and environmental hazards. Most above-ground storage tanks must undergo API 653 tank inspection services. API inspection is conducted by an experienced professional with proper inspection training.

Understanding API-653 Storage tank Inspection

American Petroleum Institute writes and maintains the inspection code for API-653 storage tank. The code has sections with details like inspection intervals, requirements for the API inspection services, and results. The code further delves into vessel repairing and its process. The inspection reports must be documented and maintained throughout the life of the vessel. Storage tank inspection can be categorized into Out-of-service vessel inspection and In-service vessel inspection.

Out of service storage tank inspection

Out-of-service storage tank inspections are also called off-stream assessments, and it is done in 10 years interval. Depending on the condition of the vessel, inspectors could require opening and cleaning of the vessel.

Inspections performed while examining Out-of-service inspection.

  • Visual Inspections:

Visual Inspection is a common type of non-destructive tank testing method. In VT, the inspectors perform a visual inspection of the storage tank’s internal and external parts. Tank inspections are highly specialized processes, and thus, only certified professionals can conduct the assessment. API-150 inspectors undergo inspection training courses similar to the API 653 training course. The inspectors go through a visual checklist to assess the condition of the tank’s foundation, heads, nozzles, ancillary equipment, pressure relief valves, and shell.

  • Ultrasonic Thickness Testing:

Ultrasonic Thickness Testing, or UTT, is another non-destructive tank testing carried out by a certified UT Inspector. Internal and external shells, heads, and nozzles of the pressure tanks are assessed while performing the ultrasonic thickness test.

Inspectors may suggest other inspections like Magnetic Particle based on the results of initial assessments.   

The final report contains the complete results of various tests and recommendations based on them. The report also mentions short and long-term corrosion rates and the remaining lifespan of the tank. The client reviews the documents to determine if the pressure tank is fit to be used further.

In-Service Storage tank Testing

Inspection of storage tanks that are still in service is often called on-stream tank testing. In-service storage tanks are required to be examined every five years.

Certified professionals usually carry out Non-destructive external visual inspection to assess the condition of the tank’s foundation, shell, heads, and nozzles.

Besides this, Ultrasonic Thickness Test is performed to evaluate the condition of the tank’s external shell, heads, and nozzles.

Once the inspection is over, a complete report is prepared that contains the examination and recommendations results.…


The value of a used car!

It’s a safe bet that we have all purchased something and a short time later kicked ourselves for being so blind. We think to ourselves, “How could I have thought this was ok?” or “Why didn’t anyone tell me?” or “How could I have been so clueless?” The pain of regret can be hard to get past. Believe me, I’m still trying to get over feeling like these stemming from the Zubaz pants craze from the 90′s…

That is a primary goal of Integrity Auto Inspections. No, not bringing back the Zubaz. Helping people make informed used vehicle purchases that bring satisfaction and peace of mind. Helping people get a clear understanding of the condition and safety of a vehicle that they are considering purchasing. It can be a large investment for most of us and to be unsure of what we are really buying can be a very scary idea. And with the assurance and convenience of our on-site inspections, we have taken away all the roadblocks to the peace of mind everyone searches for.

Hopefully, most people know that having a car inspected before a purchase is a wise thing. Simple little details that might go unnoticed to an untrained eye can be clear indicators of big trouble to someone who really knows what to look for.  This can put power in the buyer’s hands to confidently negotiate a fair purchase or even to walk away from something that might not be the best vehicle for them.

On the other side of the transaction, sellers can highlight the exceptional way they have maintained their vehicle. A inspection for them can mean small details un-covered that might have incorrectly scared away potential buyers. It can also showcase the good value that this vehicle is compared to the sea of competitors out there. If you had two potential new vehicles in mind, one impartially inspected and the other not, wouldn’t you lean towards the one willing to pay for a full disclosure of it’s true condition? It can make a world of difference.

In short, Benjamin Franklin said, “An ounce of prevention is worth a pound of cure.” With today’s transmission repairs running into several thousand dollars, it sure takes a lot of pounds of cure to balance out that preventative ounce
