TMT Extension Shaft Tool

TMT Extension Shaft Tool

Torque Tool
 
Category: Torque & FLOT
 
The TMT Extension Shaft Tool was originally designed to replace the existing drive shaft on subsea trees. The existing shafts have a triangular drive torque tool interface, but are limited in the amount of torque that can be applied to the valve stem. The tool allows higher torque to be applied to the valve.
 
The Extension Shaft tool is created from all stainless steel materials in order to achieve a maximum torque transmission capacity of 1750Nm. This maximum torque capacity is only achieved when the replacement valve insert is used. Without this insert the maximum torque that can be applied to the valve is limited by the existing valve insert to 1400Nm. 
 
TMT can customise the tool to suit your requirements.
