  • About API
  • New Releases

The American Petroleum Institute (API) has been a cornerstone in establishing and maintaining standards for the worldwide oil and natural gas industry. For more than 85 years, API has led the development of petroleum and petrochemical equipment and operating standards.

 

API standards enhance the safety of industry operations, assure quality, help keep costs down, reduce waste, and minimize confusion. They help speed acceptance, bring products to market quicker, and avoid having to reinvent the wheel every time a product is manufactured.

 

API maintains an inventory of more than 600 standards and recommended practices covering protection against fire standards, exploration standards, environmental protection standards, standards for gears, pipeline components standards, standards for welding brazing and soldering, standards for storage equipment.

 

The two most recent and important publications from API are the 10th edition of Specification 5CT, Casing and Tubing, and the 7th edition of Technical Report 5C3, Calculating Performance Properties of Pipe Used as Casing or Tubing. These new editions provide technical updates that have reached consensus within API’s Subcommittee on Tubular Goods and will now give industry consistent practices in the respective areas of the standards.
