API Inspection Services

As a registered Member Company of the American Petroleum Institute (API) we provide inspection services to API's standards.

What is it?

The American Petrolum Institute (API) publishes standards and recommended practices for the oil and natural gas industry worldwide. 

In many cases, end users require manufacturers to use API standards, and many companies are increasingly requiring third-party inspection to get more confidence in their oil and gas supply chains.

What we do.

The API standards we can certify to include:

  • API 6A 
    Which examines mechanical properties of metallic materials used for Spec 6A and Spec 17D wellhead equipment for service above 250ºF.
  • API 16A 
    Which provides requirements for performance, design, materials, testing and inspection, welding, marking, handling, storing and shipping of drill-through equipment used for drilling for oil and gas.
  • API 17D 
    Which provides specifications for subsea wellheads, mudline wellheads, drill-through mudline wellheads and both vertical and horizontal subsea trees.
  • API 53 
    Which involves the testing of blowout prevention equipment systems on land and marine drilling rigs.
  • API 505 
    Which provides guidelines for determining the degree and extent of Class I, Zone 0, Zone 1, and Zone 2 locations at petroleum facilities, for the selection and installation of electrical equipment.
  • API 580 
    Which provides users with the basic elements for developing and implementing a risk-based inspection (RBI) program for fixed equipment and piping in the hydrocarbon and chemical process industries.
  • API 620 
    Which covers large, field-assembled storage tanks of that contain petroleum intermediates and finished products, as well as other liquid products commonly handled and stored by the various branches of the industry.
  • API 650 
    Which establishes minimum requirements for material, design, fabrication, erection, and testing for vertical, cylindrical, above ground, closed and open top wielded carbon or stainless steel storage tanks for internal pressures approximating atmospheric pressure.
  • API 661 
    Which covers air cooled heat exchangers for general refinery service.
