Hub Cleaning Tool

Nexum Engineering has just finished a project on engineering, fabrication, assembling and testing of a Hub Cleaning tool for Statoil.

Customer: Statoil ASA

Project description: Engineering, fabrication, assembling and testing of a Hub Cleaning tool. The tool can be used on both inboard and outboard ends of a pipeline and is installed by inserting it into a pipe bore and activating the "gripper" mechanism. The hydraulic motor then rotates the brushes to clean the sealing surfaces of the hub.

The Cleaning tool is very light and compact and is only 0,5 meters long. The length of the tool was the main design challange in this project.
