Autobahn - Model 20.5 -Master Bushing
Solid Body Pin Drive Master Bushing as per API-7K specification suitable for 20-½".The advantage of using Pin Drive Master Bushings makes it possible to use extended split bowls in the rotary table while the Kelly bushing is in operation. The extended bowls can be used in two sizes as per API for different sizes of tubular from 2.3/8" to 10.3/4".Extended bowls provide better slip back ups & this back up is made to be used for running in heavier tubular strings without string failure due to bottle necking. These Master Bushings are provided with locks to secure the bowls into the bushings.
Split Pin Drive Master Bushing taper design as per API-7K specification suitable for 20-½". Bushing used at shallow to medium depth well. PSP (Pin Drive Split Type) models are having standard taper of Bowl No. 3 as per API to handle tubular size from 2.3/8” to 8.5/8”. This allows the use of extra long SDXL slips required for heavier load. Rise in taper by 2-½”, makes all slips rise by 2-½” which makes slip handling easier. This rise of slips distributes the load uniformly in the bushing resulting in less wear & tear of table bore. Additionally this taper provides 50% more slip support resulting in better load managing capability.
