Hello, Dear colleague

My name is Carlos F Molina, an Oil and Gas Mechanical Engineer and owner of APIEXAM.COM. Right now I am working full time as a mechanical inspector for construction projects, besides taking time to write in this website. I graduated with a Mechanical Engineer degree from the Universidad Industrial de Santander. I am an API 653 certified inspector, and I became API 580 certified in February 2, 2015. I have been working in the oil and gas field for eight years now, specially in tank repair and construction.

I have mostly worked in NDE, tank repair and alteration, new construction tanks and pipes and quality system management. I have experience in shielded metal arc welding and coating of metallic substrates. This website is intended to help people pass API certification examinations, so please feel free to ask me any questions.

I havent yet outsourced my email account. I read every email that comes through to me and I get a lot of emails. For this reason I cant always reply right away. Typically I will get back to you within 24 or 48 hours.

I want to receive APIEXAM articles

This site is built for all engineers and technicians involved in statical equipment inspection and certification, for them to be completely prepared to answer any questions about Tanks, Pipes or Pressure Vessels. I mean, there are hundreds of sites out there about oil and gas, but none like this, that will help you advance in your career for life. Use APIEXAM for all of your API related searches and activities. Here at apiexam, you will find the best study guides and information about API certifications. Best of luck to you all! Cheers! -Carlos.

    I created this website 5 years ago, but actually, I really started with it 2 years ago. There I explain the API 650 and API 653 standards more in depth. In these 2 years I have been learning the basics of creating a webpage and some CSS and Html programming. I am now beginning to deal with API 580. Come see www.apiexam.com for interesting API material.
