BLJ’s client for this project was a well-known Australian company that operates in the packaging, paper, and recycling industries. Since thier inception in the 1940’s, they have grown to be one of the largest privately-owned packaging and recycling companies in the world.

The client reached out to the team at BLJ to assist them in installing a new pipeline. The new pipeline required work to be conducted while the primary pipeline was still operational.

To allow work to continue at the plant, a team of expert BLJ technicians were engaged to perform a 4″ 150# hot tap into an 8″ Natural Gas line. Our team utilised a range of special equipment to cut the hole into the pipeline and insert a fitting, allowing for the connection of the new pipeline. Our hot-tapping services served as a safe and efficient way of making connections to pressurised systems.

Our meticulous hot-tapping procedure, performed by our highly trained personnel, allowed for the continued operation of the plant and individual pipeline while the modifications were made. This minimised shutdown time at the plant, resulting in increased efficiencies.

A prominent metalwork and fabrication company based in Brisbane encountered an issue during the commissioning phase of one of their projects. The client’s machinery flanges were leaking, jeopardising their equipment’s overall integrity and functionality. This unexpected problem demanded a swift and effective solution to prevent costly delays and potential hazards.

To address the issue, BLJ In-situ Solutions deployed a team of highly skilled technicians to assess and rectify the flange problem. Upon inspection, the technicians identified that the flanges were 7.6mm out of flatness, causing an improper sealing of the flange faces. To remedy this, they employed precision machining techniques to adjust the flange face to the required specifications.

The technicians utilised a portable Mirage flange facing machine (MM1500i) to perform the necessary machining on the flanges. However, this task was not without its challenges. In some instances, bricks had been installed within the flanges, complicating the machining process. In another scenario, the flange was installed upside down, adding an additional layer of complexity.

Following the meticulous machining of the flanges by BLJ technicians, the client experienced a significant improvement in their equipment’s performance. Upon startup, there were no leaks detected, ensuring the machinery’s functionality and safety were restored to optimal levels.

This successful project demonstrates BLJ In-situ Solutions’ expertise in precision machining and our teams ability to resolve complex issues efficiently. The client’s machinery is now operational without any leaks, ensuring their plant’s continued reliability and safety.

A dredging company in South QLD reached out to BLJ In-situ Solutions to repair a damaged shaft on one of their vessels. A team of BLJ technicians were sent on-site to perform routine Journal Turning on a 140mm OD shaft.

Marine dredging vessels are essential in creating and maintaining shipping and boating channels at major ports and so our primary goal with this project was to get them back up and running with minimal downtime and provide quality work that will last.

Our expert BLJ technicians set up our Journal Turning lathe machine on the end of the shaft and machine welded off the shaft. This machine bolts directly to the end of the workpiece and rotates around the shaft allowing our technicians to achieve the required concentricity, surface finish and circularity tolerance as specified by the client.

With our Journal Turning lathe machine, BLJ successfully repaired the damaged shaft onsite with minimal downtime or disruptions to operations. This precision machining tool assists us in performing consistent and accurate machining of cylindrical surfaces for shafts from 4″ to 11.25” in diameter.
