Petroleum and natural gas industries - High-speed special-purpose gear units

ISO 13691:2001

This International Standard specifies the minimum requirements for high speed enclosed, precision, single and double helical speed increasers and reducers with parallel shafts. It is limited to design with pinion speeds of 3000 rpm or greater, or pitch line velocities of 25 m/s or greater, for special purpose applications that are critical to the continued operation of specific installations. By agreement, this International Standard may be used for other services.
