The American Petroleum Institute (API) and International Standards Organization (ISO) are two of the most respected standard associations globally and are especially in force in the North American oil & gas industry.
Our flexible coupling customers rely on these API & ISO organizations technical committees to research and advise on conditions that may affect the high performance requirements of rotating equipment.
End users will either use these API / ISO standards for their equipment or enhance them to ensure they receive quality manufactured equipment that performs to the intended field conditions.
In the oil & gas industries and especially in the refining marketplace compliance to the API610, API671, API676 or ISO 10441 standards is required for a majority of flexible coupling applications. The AGMA 9000 Class 9 is also a base for coupling design and supply under the API standards.
The coupling compliance and approval process requires a review of either the applicable API Standards, the customer Standards or enhanced Standards incorporating both API and Customer requirements.
The approval process involves detailed review of the specific application criteria; examples would be material, tolerances, component design, speed considerations and balance for various flexible coupling rotating equipment installations.
One must understand why the customer has specified either the API/ ISO standards, the API / ISO package in conjunction with client’s specifications or client’s standalone requirements.
By understanding our customer’s position the suppliers will have a positive effect on their submission for the technical and supply approval process.
