We serve, but are not limited to the marine, steel, petrochemical and general industry.

Line Boring (up to 2500mm diameter)

We have a various range of line boring machines, of which we have designed and manufactured our largest. Supremely made to ensure absolute precision set-up, using Taylor Hobson optical alignment (through CCTV if required) telescopes. Our team has vast experience on all application as shown below.

On-site Machining Process Analysis

If required, all on-site machining operations are recorded and incorporated onto our comprehensive "Pre/Post Machining Certificates".

Before and after photographs are taken in addition to survey results.

Example of photographs entered onto certificates (on right).

Typical petrochemical on-site machining applications
Flange machining - 1" I/D up to 80" O/D
Limited access flange facing - up to 6" O/D
Heat exchanger / Shell machining
Pipe cutting and weld prepping
Bedplates / Linear milling
Drilling / Tapping / Rota Broaching

 

machining the back face of an exchanger bundle








Machining the back face of an exchanger bundle.

This involves careful setting of the machine that is mounted onto the exchanger face while the cutting arm reaches around the back to machine the gasket face and return it to perfect condition.


machining the slot in an exchanger bundle











Machining the slot in an exchanger bundle.

Our milling machine is attached to the front of the exchanger face after the front gasket face has been machined. Then the slot width and depth is machined to align with the gasket face for a perfect seal.

 

flange facing the dome-end gasket face








Machining the Dome-end gasket face.

This 68-inch diameter dome end to shell had a fatal leak without any visual flaws. Machine was installed and survey showed an accumulative "out of flatness" error of 0.078" to the shell. Machining has returned gasket face - flat!
